ASM 11gR1 Installation & Configuration

Linux下Weblogic 11g R1安装和配置2013-12-07 19:36:05| 分类：server|举报|字号订阅转自：/juluce133/article/details/97743271. 安装前1 确定weblogic版本被认证首先请确认您要安装的Weblogic版本所在的平台已通过了BEA的认证，完整的认证平台列表请参考/wls/certifications/certs_810/index.html1.2 确定一个安装目录，建议该目录下至少有1个G的空间，可以使用du来察看磁盘空间的使用情况（实际情况是我们大多数人都没有这么大的内存，如果你有256，我想也是可以的，因为你是用来自己开发，不是用来对外发布的）1.3 创建一个BEA用户组帐号groupadd –g GID groupname说明：GID代表创建组的ID，一般大于500比如：groupadd –g 600 bea（你可以自己建一个Weblogic组＆Weblogic帐户，官方也是这样建议的，但是你也可以不这么做。

用你的常用帐户作为工作目录也可以）1.4 创建一个Weblogic用户帐号useradd –d userhome –g GID username说明：userhome 代表用户的主目录，GID 为前一步创建的组ID比如useradd –d /home/Weblogic–g 600Weblogic添加Weblogic用户和Weblogic组# groupadd weblogic# useradd –g weblogic–m weblogic# passwd weblogic2. 安装时Weblogic在Linux平台下的安装方法一般有三种:图形窗口模式，控制台模式，无人守护安装模式。

由于控制台模式的使用最为广泛且不受任何其它硬件条件的限制。

（所以我这里只介绍控制台安装模式，图形模式和win里面的完全一样，各位就不要问我怎么安装呢吧！）2.1 安装JRE环境Weblogic安装程序需要JRE的支持，根据安装平台的不同，Weblogic的安装介质也分为两类，一种自带了JRE（后缀名为.bin）,一种需要下载平台厂商所提供的JRE环境(后缀名为.jar)，以wls1034_linux32.bin（本系统安装的就是这个版本，自带jre）为例，目前所支持的UNIX/Linux平台你可以到官方查询。

Oracle 11gR2 for Linux 安装一．硬、软件环境：1.硬件：IBM x3650 M2，2颗Intel Xeon E54052.0Ghz CPU,2G*2=4G内存，3块146G SAS硬盘，做raid0配置。

2.软件：RHEL5.4 32位版本，linux_11gR2_grid，linux_11gR2_database，SecureCRT6.1,Xmanager3.0。

注：Xmanager3.0用于上传软件文件和x窗口映射。

二．安装完操作系统后以root用户创建oracle相关的用户和组参照oracle的官方文档，创建两个用户grid和oracle，grid用户用来安装grid 软件，oracle用户安装oracle软件，数据库文件使用ASM管理。

注：#开头的命令对应root用户执行，$开始的命令对应grid和oracle用户首先，创建四个组oinstall, dba, asmadmin, asmdba：#groupadd -g 1000 oinstall#groupadd -g 1100 dba#groupadd -g 1200 asmadmin#groupadd -g 1300 asmdba再创建两个用户grid和oracle：#useradd -u 1001 -g oinstall -G asmdba,asmadmin,dba grid#passwd grid#useradd -u 1002 -g oinstall -G dba,asmdba oracle#passwd oracle创建目录和授权：#mkdir -p /u01/app/grid 注:此目录用来安装grid软件#chown -R grid:oinstall /u01#chmod -R 775 /u01#mkdir -p /u02/app/oracle 注：此目录用来安装oracle软件#chown -R oracle:oinstall /u02#chmod -R 775 /u02三．所需的rpm包，参照oracle官方文档，根据不同的操作系统版本，rpm包的版本有所区别，包名肯定是一样的。

PurposeThe objective of this document is to explain the installation and configuration of Oracle HTTP Server 11g R1(11.1.1.6.0). This includes setting up of server details, configuration of compression rules and enabling SSL.2. Introduction to Oracle HTTP Server (OHS)Oracle HTTP Server is the Web server component for Oracle Fusion Middleware. It is based on Apache web server, and includes all base Apache modules and modules developed specifically by Oracle. It provides a HTTP listener for Oracle WebLogic Server and the framework for hosting static pages, dynamic pages, and applications over the Web. Key aspects of Oracle HTTP Server are its technology, its serving of both static and dynamic content and its integration with both Oracle and non-Oracle products.Oracle HTTP Server consists of several components that run within the same process. These components provide the extensive list of features that Oracle HTTP Server offers when handling client requests.Following are the major components:2.1 HTTP ListenerOracle HTTP Server is based on an Apache HTTP listener to serve client requests. An HTTP server listener handles incoming requests and routes them to the appropriate processing utility.2.2 Modules (mods)Modules extend the basic functionality of Oracle HTTP Server, and support integration between Oracle HTTP Server and other Oracle Fusion Middleware components. There are modules developed specifically by Oracle for Oracle HTTP Server. Ex: mod_wl_ohs, mod_plsqlOracle HTTP Server also includes the base Apache and third-party modules out-of-the-box.These modules are not developed by Oracle. Ex: mod_proxy, mod_perl3. Installation of OHS 11gInvoke the setup exe to start the installationSelect Skip Software UpdatesSelect Install and ConfigureSelect only Oracle HTTP ServerEnter the required OHS instance and component namesThis completes the installation of Oracle HTTP Server with <Instance> and <component>. Example: Instance is instance1 and component is ohs1.If you would like to change the port after the installation(OHS Listen Port) edit$ORACLE_INSTANCE/config/OHS/<component_name>/httpd.conf and change the listen port.NOTE: This port is for http protocol and not for https.4. Configure Oracle HTTP Server infront of Weblogic ServerIn Oracle HTTP Server requests from Oracle HTTP Server to Weblogic server are proxied usingmod_wl_ohs module. This configuration file needs to be modified to include the Weblogic server and port details.mod_wl_ohs.conf file is located at${ORACLE_INSTANCE}/config/OHS/{COMPONENT_NAME}/mod_wl_ohs.confAdd the below directives to mod_wl_ohs.conf file.4.1 For WebLogic in single instance<Location /<<context/url>> >SetHandler weblogic-handlerWebLogicHost <<server name>>WeblogicPort <<port>></Location>Example:<Location /FCJNeoWeb>SetHandler weblogic-handlerWebLogicHost wlserver1WeblogicPort 7707</Location>This will forward /FCJNeoWeb from HTTP server to /FCJNeoWeb on WebLogic Server wlserver1: 77074.2 For Weblogic instances in cluster<Location /<<context/url>> >SetHandler weblogic-handlerWebLogicCluster <server1>:<port1>,<server2>:<port2></Location>Example<Location / FCJNeoWeb >SetHandler weblogic-handlerWebLogicCluster wlserver1:7010, wlserver2:7010</Location>This will forward /FCJNeoWeb from HTTP server to /FCJNeoWeb on WebLogic Cluster wlserver1:7010 and wlserver2:70105.Enable “WebLogic Plug-In Enabled” flag in weblogicThis flag needs to be enabled in weblogic if it is accessed through proxy plugins. When the WebLogic plugin is enabled, a call to getRemoteAddr will return the address of the browser client from the proprietary WL-Proxy-Client-IP header instead of the web server.a. Plugin flag at managed server leveli. Click on ‘Environment’- > 'Servers' -> '<ManagedServer>' -> 'General' -> 'Advanced'ii. Check the 'WebLogic Plug-In Enabled' box.iii. Click 'Save'iv. Restart the Server.b. Plugin flag at domain levelv. Click on <Domain> -> 'Web Applications'vi. Check the 'WebLogic Plug-In Enabled' box.vii. Click 'Save'viii. Restart the server.6. Compression rule settingContent compression in Oracle HTTP Server is done using mod_deflate. This can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving on server traffic. However, compressing files causes a slightly higher load on the server, but clients' connection times to server is reduced.6.1 Loading mod_deflatemod_deflate is used for compression in OHS and this is installed in Oracle HTTP Server under location "${ORACLE_HOME}/OHS/modules/mod_deflate.so"But it might not be loaded.To load the file add the below directive in mod_wl_ohs.conf fileLoadModule deflate_module "${ORACLE_HOME}/OHS/modules/mod_deflate.so"6.2 Configuring file typesmod_deflate also requires to specify which type files are going to be compressed.In the LOCATION section of mod_wl_ohs.conf file add the below entries.AddOutputFilterByType DEFLATE text/plainAddOutputFilterByType DEFLATE text/xmlAddOutputFilterByType DEFLATE application/xhtml+xmlAddOutputFilterByType DEFLATE text/cssAddOutputFilterByType DEFLATE application/xmlAddOutputFilterByType DEFLATE application/x-javascriptAddOutputFilterByType DEFLATE text/htmlSetOutputFilter DEFLATEImages are supposed to be in a compressed format, and therefore are bypassed by mod_deflate.6.3 httpd.conf file changesThis is a server configuration file which typically contains directives that affect how the server runs, such as user and group IDs it should use, and location of other files. Cross check the existence of mod_wl_ohs.conf include in httpd.conf file.httpd.conf file is present under location“${ORACLE_INSTANCE}/config/OHS/{COMPONENT_NAME}/httpd.conf”In this file cross check for the below entryinclude "${ORACLE_INSTANCE}/config/OHS/${COMPONENT_NAME}/mod_wl_ohs.conf"If above include entry is not present, then add the above include section.7. Configuring SSL for Oracle HTTP ServerSecure Sockets Layer (SSL) is required to run any Web site securely. Secure Sockets Layer (SSL) is an encrypted communication protocol that is designed to securely send messages across the Internet.Reading of “SSL_Configuration on Weblogic” document provide d as part of FCUBS installation isrecommended before proceeding with further setup.In Oracle HTTP server, SSL configuration can be done between1. Browser to Oracle HTTP Server(Mandatory)2. Oracle HTTP Server to Oracle Weblogic Server(If required)7.1 SSL configuration for Inbound Request to Oracle HTTP ServerPerform these tasks to enable and configure SSL between browser and Oracle HTTP Server.1. Obtain a certificate from CA or create a self signed certificate.2. Create an Oracle Wallet which contains the above SSL Certificate. The default wallet that isautomatically installed with Oracle HTTP Server is for testing purposes only. The default wallet is located in "${ORACLE_INSTANCE}/config/OHS/${COMPONENT_NAME}/keystores/default"3. Configuring Wallet in ssl.conf file7.1.1 Create a new Wallet and import Certificate1. Go to the \Oracle_WT1\bin\launch.exe, this will launch your wallet manager2. Click on Create new and then click no option.3. Enter the wallet password and click on OK, this will create a new wallet.4. Not it will ask for certificate request creation, Click on NO to proceed5. Right click on trusted certificates and then import trusted certificate.6. Browse to the folder where certificate is stored and click on Open7. Click on Save Wallet button on the left side navigation and save the wallet either to defaultlocation("${ORACLE_INSTANCE}/config/OHS/${COMPONENT_NAME}/keystores/default") or folder of your choice.8. Click on Wallet tab and enable Auto Login7.1.2 Configuring Wallet in ssl.conf fileIn ssl.conf file the newly created wallet need to updated. This file is located under folder"${ORACLE_INSTANCE}/config/OHS/${COMPONENT_NAME}/1. Change the SSLWallet directive to point to the location of new wallet created.SSLWallet "${ORACLE_INSTANCE}/config/${COMPONENT_TYPE}/${COMPONENT_NAME}/keystores/"2. Change the Listen port number in ssl.conf file to the SSL enabled port, by default the value is 44437.2 Configuring SSL between Oracle HTTP Server and Oracle Weblogic ServerSSL for outbound requests from Oracle HTTP Server are configured in mod_wl_ohs.Refer to “SSL_Configura tion on Weblogic” document for weblogic server setting mentioned in below section.7.2.1 Turn off KeepAliveEnabledThe below parameter in mod_wl_ohs should be turned off, by default it is on. Add the below directive under LOCATION section of mod_wl_ohs fileKeepAliveEnabled OFF7.2.2 To enable one-way SSL1. Generate a custom keystore identity.jks for Weblogic Server containing a certificate.2. At Identity section in Keystores tab in weblogic Admin Console for server seta. The custom trust store with the identity.jks file locationb. The keystore type as JKSc. The passphrase used to created the keystore3. Copy the certificate to Oracle HTTP Server and import the new certificate into OHS wallet as a trustedcertificate.4. Add following new directive in mod_wl_ohs.conf to point to the wallet locationWlSSLWallet "${ORACLE_INSTANCE}/config/OHS/{COMPONENT_NAME}/keystores/default"5. Change the port in mod_wl_ohs file to point to SSL port of Weblogic server.6. Restart both Weblogic Server and Oracle HTTP Server7.2.3 To enable two-way SSL1. Perform one-way SSL configuration steps2. Generate a new trust store, trust.jks for Weblogic server3. Keystore created for one-way SSL could be used, but it is recommended to create a separate truststore4. Export the user certificate from Oracle HTTP Server wallet, and import it into truststore created above5. At Trust section in Keystores tab in Weblogic Admin Console for the server seta. The custom trust store with the trust.jks file locationb. The keystore type as JKSc. The passphrase used to created the keystore6. Under the SSL tabEnsure trusted CA is set as from Custom Trust Keystore.7. Restart Weblogic Server8. Sample Configuration Fileshttpd.conf mod_wl_ohs.conf ssl.conf9.

ASM中的offline和drop操作当一个ASM磁盘不可用时，ASM会把它从磁盘组里移除，对吗？要看情况，通常取决于ASM版本和磁盘组的冗余级别。

因为一个external冗余的磁盘组会直接被dismount，所以主要关注normal和high冗余磁盘组的情况。

ASM 10g版本，磁盘会被直接drop。

从11gR1，一个磁盘不可用时会先被offline，此时disk repair计时器开始介入，如果计时器达到磁盘组DISK_REPAIR_TIME 属性值时，这个磁盘会从所属的磁盘组中drop 掉。

如果这个磁盘在计时器过期前恢复可用，那么它的状态会变回online，不会被drop。

但是ASM是如何发现磁盘恢复可用又有什么机制将它恢复online呢?当一个磁盘不能被ASM或者ASM客户端读或写时，会被认为不可用。

数据库是一种典型的ASM客户端，但ASM客户端并不只限于是数据库。

磁盘会因为各种原因变成不可用，本地硬盘的SCSI线缆受损，存储的SAN交换机或者网络故障，NFS空间的服务器故障，双活场景的站点故障，又或是磁盘本身故障等各种场景。

无论是哪种情况，ASM或者是ASM客户端会报IO错误，然后ASM会进行相应的处理。

在ASM 10G时，ASM会立即Drop变成不可用的磁盘。

这会触发一个尝试恢复数据冗余的重平衡操作。

一旦重平衡过程完成，数据冗余度会恢复，同时磁盘会被移除出磁盘组。

一旦磁盘不可用的故障被解决，可以通过alter diskgroup命令将磁盘重新添加回磁盘组。

例如：alter diskgroup DATA add disk 'ORCL: DISK077'; 这又会再次触发一个重平衡操作，一旦重平衡过程完成，磁盘会恢复成为磁盘组成员。

但是如果多个磁盘同时发生故障，又或者一个磁盘故障在重平衡过程中又有磁盘故障会导致什么结果？这取决于多个因素，磁盘组的冗余度、磁盘是否来自于相同或不同的failgroup和故障磁盘是否是partner关系。
