The customized technology of Linux MDS provides a solution where the operating system and core services are managed for you. At the same time, you have full root access to your files and programs.Purpose of this DocumentThis document provides information for basic administration of your account. It provides important information about creating users, configuring email and subhosts (or virtual hosts), and server software management to help you begin using your account. This document describes server management from a shell command line and assumes you understand shell clients and command-line interaction with Linux (or other UNIX-like) servers. If you do not use shell command line or are not familiar with shell interaction, you can install and use the CPX: Control Panel Web interface. For more information about CPX: Control Panel, see customer documentation for the CPX: Control Panel, which includes a guide to getting started with that Web interface. Your account includes several v-commands. These commands, created specifically for your product, enable server administration. Some examples discussed in this document include vadduser, vrmuser, and vaddhost.Navigating this DocumentThis document describes how to add, remove, or configure server users, email addresses, aliases, virtual user table (virtusertable) entries, catchalls, and subhosted Web site configurations. In addition, this document describes how to use custom installation scripts (vinstall and vuninstall) which enable you to install and/or remove programs, packages, and features. Refer to the following sections for instructions:•“Manage Users” on page 2.•“Manage Email” on page 4.•“Manage Subhosts” on page 6.•“Use Vinstall and Vuninstall” on page 8.Manage UsersAs part of the automatic maintenance provided with your account, your server contains several necessary root and application users by default, such as root, ftp, pop, and the administrative user (created when you ordered the server). You can create additional users and offer them services, such as FTP, email, and shell access. This section describes adding, managing, and removing users.Note: When adding, configuring, or removing users, you must be the root user. You can become the root user by typing su- at the command line and supplying the root user password.Adding UsersTo add a server user, follow these steps from the command line:1.Type vadduser and press Enter.2.Further instructions and information for vadduser will display during this step and throughout the vadduserprocess. Press Enter to continue after reviewing the information.3.Type the username for the user you wish to create and press Enter. Usernames consist of alphanumericcharacters up to sixteen (16) characters. The first character cannot be a number.Note: The operating system supports multi-byte characters in usernames, but will not support the following multi-byte characters because they are reserved for system use: @, $, #, / or \. (To learn more about using multi-byte characters in usernames, refer to the following Web site: /c/charset.html.)4.Type the user’s password and press Enter. Use a password that will not easily be guessed. A combination ofuppercase and lowercase letters, numbers, and symbols is an example of a more secure password. If aparticularly insecure password is entered, the system will prompt you to enter a more secure password. You will need to type the same password twice for confirmation.5.Type the user’s full name and press Enter. This information displays when you use system tools such asvlist (used to list all server users).6.Type the user’s home directory path and press Enter. The vadduser command simplifies this step andprovides a recommended Linux MDS path for you. You can press Enter without typing a path to select this default.7.Select the services to offer the user. This is a toggle-style prompt, with the FTP and email services enabled forthe user by default. Available services include ftp, mail, and shell. Type the service name at the prompt and press Enter to toggle the service on or off. Press Enter when done.Caution:Shell access enables control over many aspects of the server. Shell access should only be offered to trusted users. With shell access users can potentially change files or settings affecting your entire server. Use care when offering the shell service to users.8.Type the user’s allotted file system (or filesystem) quota in megabytes (MB). The quota must be a wholenumber. Enter 0 to give the user an unlimited quota (up to the free space available for your plan). Press Enter to complete the addition of the user.Administering and Configuring UsersTo list all existing server users, type vlist at the command prompt.To change the full name, services offered, or quota for a user, follow these steps from the command line:1.Type vedituser and press Enter2.Type the name of the user in question and press Enter.3.Select the services to offer the user. This prompt is a toggle-style prompt, with the FTP and email servicesenabled for the user by default. Available services include ftp, mail, and shell. Type the service name at the prompt and press Enter to toggle the service on or off. Press Enter when done.4.Type the user’s allotted filesystem quota in megabytes (MB). The quota must be a whole number. Enter 0 togive the user an unlimited quota (up to the free space available for your plan). Press Enter to complete the addition of the user.To change a server user’s password, follow these steps from the command line:1.Type passwd name, where name is the username of the user in question. Press Enter.2.Type the new password and press Enter. Type the new password again for confirmation and press Enter. Ifthe two passwords do not match, you will be prompted to type them again.Note: Use a password that will not easily be guessed. A combination of uppercase and lowercase letters, numbers, and symbols is an example of a more secure password. If a particularly insecure password is entered, the system will prompt you to enter a more secure password.Removing UsersTo remove a server user, follow these steps from the command line:1.Type vrmuser and press Enter.2.Type the username of the user to remove. If the user does not exist, the system will indicate the user does notexist in the password database and exit the removal process.3.The system will display the password entry for the user to be removed and ask you to confirm the removal ofthe user. Type yes if the information is correct or no to exit the process. Press Enter.Caution:Use extreme caution when removing the home directory of users (step 4). You will not be warned if Webcontent or other important information is stored in the user’s home directory. Removing a user’s homedirectory will immediately delete all contents of that directory.4.The system will display the user’s home directory and ask if you wish to remove it. Type yes and press Enterto remove the directory and complete the removal of the user, or type no and press Enter to remove the user, but keep the user’s home directory and its contents.Note: If you remove a user, but not the files or home directory they own, the files or directories of the removed user will be owned by a system-generated four digit ID (for example: 1007).Manage EmailAll user email boxes reside in the /var/mail directory. The system automatically creates email boxes for server users. If no other email routing settings (such as aliases or virtusertable entries) are configured, the username is the default valid email for all domains that resolve to the server. For example, if and resolve to the server, for the user bob, both *************** and *************** would deliver email to the/var/mail/bob email box. The system checks for matches in email routing and addresses in the following order and delivers to the first match it finds:•virtusertable entries•aliases•usersThis section describes virtusertable entries, catchall, and alias configurations.Note: To edit the virtusertable entries and aliases files, you must be the root user. You can become the root user by typing su - at the command line and supplying the root user password.Configuring Virtusertable entriesVirtual user table (virtusertable) entries route the full email address (both sides of the @) to a local user, alias, or remote email address, but cannot map to files or programs. Only aliases can route email to a file or program. A virtusertable entry consists of the virtusertable entry and its destination, or mapping. For example, a virtusertable entry for *************** could be mapped to the user bob with the following virtusertable entry: ******************Virtusertable entries enable you to create email addresses without the need to create a corresponding user. For example, a virtusertable entry for *************** could be mapped to ******************** with the following virtusertable entry:******************@In this example, would indicate a remote domain which does not resolve to your account. Specify virtusertable entries in the /etc/mail/virtusertable file, with one virtusertable entry per line. The virtusertable.sample file provided with each server contains example virtual user tables. You can change virtusertable entry settings by editing the virtusertable file and then executing a hash command:makemap hash /etc/mail/virtusertable < /etc/mail/virtusertableThe hash command rebuilds the virtusertable.db file which includes the new virtusertable entries. Configuring CatchallsCaution:Catchall virtusertable entries should be used sparingly. Spammers often send many emails to every conceivable address for a domain, often numbering in the thousands. A catchall virtusertable entry wouldcause the system to receive all of these emails and map them to the recipient.A special virtusertable entry called a catchall maps all email not otherwise configured with a virtusertable entry for a given domain to a single recipient. For example, the following catchall virtusertable entry would map all email not configured with another virtusertable entry for the domain to the joe user:@ joeIf no virtusertable entry exists for an email address, and a catchall virtusertable entry is configured for the domain, the system would route all email sent to that address to the catchall virtusertable entry.Configuring AliasesEmail aliases forward email to a user, another alias, email address, list of addresses, file, or program. Aliases enable you to create email addresses without the need to create a corresponding user. For example, the following alias would forward email sent to ******************** to the stan user:webmaster:stanAliases also enable you to send email to a list or to a program. For example, the following alias would forward email sent to ********************* to the bob, joe, and stan users:sales:bob,joe,stanFor long email lists, place the emails in a file, one address per line, and use the include option. For example, the following alias would forward email sent to ********************* to all addresses in the /lists/promotion file:promotion: :include:/lists/promotionSpecify aliases in the /etc/aliases file, with one alias per line. You configure the aliases by editing the aliases file according to your needs. After making changes to the file, execute the newaliases command from the command line to load the new aliases into the system. Changes to aliases will not be used by your account until you execute newaliases.Note: The system only considers the first portion of the email address (before @) for aliases. To map an entire email address to a certain recipient, use a virtusertable entry.Manage SubhostsYour account enables you to configure multiple Web sites and domains in addition to the main domain of the server. The main domain or site for the server is called the hostname. Place the Web content for this site in the/www/htdocs directory.You may have configured a custom hostname during the order process. To aid with configuring and testing your server, all Linux MDS servers receive a temporary domain name, or temp domain, which resolves to your account. This domain can be used if the custom hostname is inaccessible or does not yet resolve to your server.Other domains or sites hosted by your server are called subhosts. This section explains adding, removing, and configuring subhosts.Note: To execute the vaddhost command or edit the httpd.conf file, you must be the root user. You can become the root user by typing su - at the command line and supplying the root user password.Adding a SubhostSubhosts are configured with the Apache VirtualHost directive. The Apache Web server looks for VirtualHost entries in the /www/conf/httpd.conf file. The vaddhost v-command assists in the creation of the subhost configuration VirtualHost tags in your Apache configuration file.Subhost configuration includes many variables. While separated here into three sections, the entire process includes all three and you must complete all of them to entirely configure the subhost.To begin the subhost configuration and specify the domain and administrator, follow these steps from the command line:1.Type vaddhost and press Enter. Instructions and information for vaddhost will display during this step andthroughout the vaddhost process.2.Type the domain for the subhost (, for example), any secondary domains (,, etc), and any other domains used for this subhost, pressing Enter after each. The firstdomain entered will be the main domain for the subhost. Additional variations will be aliases that point to the main domain. Press Enter without any text after providing all variations to move to the next step.Note: The hostname or subhost usually consists of the top-level domain () instead of a canonical name such as . Canonical names are usually added as secondary domains or aliases.3.The system displays the list of domains and variations for verification. Type y and press Enter to continue ortype n and press Enter to input the domains again.4.Type the username of the user who will administer the subhost and press Enter. (Press Enter without any textto display a list of existing users.) This user should be the owner of the site files and folders; otherwise the Web server will not be able to load the site.5.Verify the information and type y and press Enter to continue or type n and press Enter to input the usernameagain.To continue the configuration and specify SSL, administrative email, and document root (Web directory) settings, follow these steps from the command line:1.To enable SSL for the subhost type y and press Enter or type n and press Enter to not enable SSL for thesubhost.2.Verify the information and type y and press Enter to continue or type n and press Enter to input the SSLinformation again.3.Type the email address of the subhost administrator and press Enter.4.Verify the information and type y and press Enter to continue or type n and press Enter to input the addressagain.5.Type the path for the subhost Web directory, or document root, on the server. The vaddhost commandsimplifies this step and provides a recommended path for you. You can press Enter without typing a path to select this default, which will create a subhosted directory in the home directory of the user specified in step 4.6.Verify the information and type y and press Enter to continue or type n and press Enter to input the pathagain.To continue the configuration and specify log and cgi-bin settings, follow these steps from the command line:1.Select an option for the subhost transfer log and press Enter.2.Verify the information and type y and press Enter to continue or type n and press Enter to choose the transferlog configuration again.3.Select an option for the subhost error log and press Enter.4.Verify the information and type y and press Enter to continue or type n and press Enter to choose the errorlog configuration again.5.Select an option for the subhost cgi-bin and press Enter. This will enable the subhost to execute scripts andprograms.6.Verify the information and type y and press Enter to continue or type n and press Enter to choose the cgi-binconfiguration again.7.The system will display the VirtualHost entry to be added to the httpd.conf file for confirmation. Type yand press Enter to add the entry to the httpd.conf file, or type n and press Enter to abort the vaddhost process.8.If you typed y to accept the entry, type y and press Enter to restart the Web server and complete the subhostaddition.Note: Press ctrl+c to exit the vaddhost process at any time. This immediately cancels vaddhost and any subhost configuration entered during the vaddhost process is lost.Configuring a SubhostYou may configure a subhost further by editing the VirtualHost entries for the subhost in the/www/conf/httpd.conf file. Execute the restart_apache command from the command line after editing the file to restart the Web server and make the changes effective.Removing a SubhostThe /www/conf/httpd.conf file contains the configuration for subhosts. To remove the subhost configuration from the Web server, follow these steps:1.Edit the httpd.conf file and remove the VirtualHost entries for the subhost in question.2.After modifying the httpd.conf file, execute the restart_apache command from the command line torestart the Web server.3.Remove any unneeded files or directories for the subhost from the server.Note: See “Removing Users” on page 3 for further information about subhost files and directories assigned to a user and considerations when removing that user.Use Vinstall and VuninstallYour server contains another feature unique to Linux MDS which makes configuration of your server easier. The vinstall v-command enables the installation and configuration of programs to your server. Programs available for installation through vinstall have been configured specifically for the Linux MDS system and enable you to utilize a variety of programs without complicated manual configuration.The vuninstall utility removes files and configurations created by the vinstall utility. This section describes using vinstall and vuninstall to list available programs, find information about them, install, and/or remove programs.You can execute the vinstall utility using interactive commands, or supply the needed information as command-line options to avoid the interactive vinstall prompts. Refer to Table 1 for a list of the possible vinstall actions you can execute and the interactive and non-interactive commands for each. Substitute vuninstall for vinstall when removing programs.Note: Certain programs may prompt for further information as part of their own installation process, even when using the non-interactive vinstall commands.Table 1: vinstall command optionsActions Interactive Command Non-interactive CommandEnter interactive mode vinstall n/aList available programs ? vinstall –lFind additional information about aprogram n/aprogramEnter install mode install n/aInstall a program programvinstall program(while in install mode)Exit interactive mode quit n/aNote: Press ctrl+c at any time to exit the interactive or non-interactive vinstall process. Use this option with caution as it immediately cancels vinstall and may leave installations and programs incomplete and non-functional.。

Hadoop平台搭建与应用教案教学过程教学提示项目2 Hive环境搭建与基本操作任务2.1 Hive的安装与配置Hive是基于Hadoop的一个数据仓库工具，可以将结构化的数据文件映射为一张数据库表，并提供完整的SQL查询功能，将类SQL语句转换为MapReduce任务，如图2-1所示，并执行此任务。

图2-1 将类SQL语句转换为MapReduce任务1．Hive数据结构Hive中所有的数据都存储在HDFS中，Hive中包含以下数据结构。

（1）Table：Hive中的Table和数据库中的Table在概念上是类似的，每一个Table在Hive中都有一个相应的目录存储数据。

（2）Partition（可选）：在Hive中，表中的一个Partition对应于表中的一个目录，所有的Partition的数据都存储在对应的目录中。

（3）Bucket（可选）：Bucket对指定列计算Hash，Partition根据某个列的Hash值散列到不同的Bucket中，目的是进行并行处理，每一个Bucket对应一个文件。

2．Hive架构Hive架构如图2-2所示。

Hadoop和MapReduce是Hive架构的基础。

用户接口主要有CLI客户端、HiveServer客户端、HWI客户端和HUE客户端（开源的Apache Hadoop UI系统），其中最常用的是CLI客户端。

在CLI客户端启动时，会同时启动一个Hive副本。

在Windows中，可通过JDBC连接HiveServer的图形界面工具，包括SQuirrel SQLClient、Oracle SQL Developer及DbVisualizer。

HWI通过浏览器访问Hive，通过Web控制台与Hadoop集群进行交互来分析及处理数据。

MetaStore用于存储和管理Hive的元数据，使用关系数据库来保存元数据信息（MySQL、Derby等），Hive中的元数据包括表的名称、表的列和分区及其属性、表的属性（是否为外部表等）、表的数据所在目录等。

coefficientUsagereciprocity_cor(g)Argumentsg igraph object.should be a directed graph14sample_coreseqDetailsThe usual definition of reciprocity has some defects.It cannot tell the relative difference of reci-procity compared with purely random network with the same number of vertices and edges.The useful information from reciprocity is not the value itself,but whether mutual links occur more or less often than expected by chance.To overcome this issue,reciprocity can be defined as the correlation coefficient between the entries of the adjacency matrix of a directed graph:i=j (a ij−a )((a ji−a )i=j(a ij−a )2where a’is the density of g.This definition gives an absolute quantity which directly allows one to distinguish between recip-rocal(>0)and antireciprocal(<0)networks,with mutual links occurring more and less often than random respectively.ValueReciprocity as a correlationAuthor(s)David SchochReferencesDiego Garlaschelli;Loffredo,Maria I.(2004)."Patterns of Link Reciprocity in
