RedHat linux7 虚拟化+集群安装精简手册

以Red Hat Linux 7.0为例说明安装过程，如下：塞入第一张光盘，让计算机从CDROM启动，马上就出现了简洁的欢迎信息。

敲回车，可以进入默认的安装模式-图形界面，鼠标操作，基本和6.1、6.2类似。

敲入“text”，可以进入文本安装模式，和6.0以前的版本相似。

不支持鼠标，需要使用键盘操作，主要是为了兼容。

如果你的计算机使用图形模式不好用，比如，屏幕出奇的大，按钮怎么也找不到，那就使用此模式。

打入“expert”，可以进入所谓的专家模式，实际上就是安装程序把所有的步骤都交给了你，随遍你怎么设置，如果你的机器有些特殊的硬件，安装程序无法正确配置，那就试试这样的方式。

敲入“linux rescue”，会进入“救援”模式，主要用于原有的Linux系统无法正常启动的情况。

使用这个办法，实际上你是进入了一个微型的Linux系统，里面有许多可以用来拯救操作系统的工具程序。

如果你有特殊硬件的安装驱动盘，就敲入“linux dd”，它会提示你插入软盘，读取进系统。

以便更好的利用它们。

敲回车进入默认安装模式，内核启动后，出现语言选择选单，18种语言，可惜就是没有中文。

选“english”，再挑键盘，鼠标。

值得一提的是，我的双飞燕4D+鼠标自动的被认出三键。

要知道，第三键在Linux环境下的作用很大。

许多操作可以用它来实现，如果你没有三键鼠标，就使用模拟三键的方法，左右键同时按下，即表示第三键。

安装界面非常好用，左面有及时详尽的帮助信息，右面是选项。

完全鼠标操作。

在系统安装的阶段，最重要的事情是看清楚左面的说明！因为许多的朋友都有过惨痛的教训-漫不经心，结果，硬盘里面所有的东西都被干掉了，系统瘫痪。

简直欲哭无泪，好些人不停的到网上请教恢复的办法。

这里详细说明一下，RedHat 7.0有两大类安装方式：Install 或者upgrade。

前者包含下面三种选择：WorkStation、ServerSystem、Custem System。

一、服务器版本查看cat /etc/redhat-release二、新建目录：mkdir -p /softwares三、解压下载3.4.9版本，解压到/softwares目录cd /softwarestar zxvf zookeeper-3.4.9.tar.gz四、配置将conf目录下的zoo_sample.cfg改为zoo.cfgcd /softwares/zookeeper-3.4.9/confmv zoo_sample.cfg zoo.cfgmkdir -p /softwares/zookeeper-3.4.9/data查看配置cd /softwares/zookeeper-3.4.9/conf【yum install vim】vim zoo.cfg注意其中tickTime=2000dataDir=/softwares/zookeeper-3.4.9/dataclientPort=2181五、启动单机测试cd /softwares/zookeeper-3.4.9/bin(没有的话使用chmod u+x *.sh使以sh为扩展名的脚本都有运行权限) ./zkServer.sh start./zkServer.sh status使用命令./zkCli.sh -server 127.0.0.1:2181连接到zookeeper服务。

六、配置主机名和ip的映射vim /etc/hosts其中编辑增加如下内容192.168.18.202 logsrv01192.168.18.203 logsrv02192.168.18.208 logsrv03192.168.18.201 obsrv01七、配置Zookeeper的配置文件cd /softwares/zookeeper-3.4.9/bin./zkServer.sh stopcd /softwares/zookeeper-3.4.9/confvim zoo.cfg在clientPort=2181下增加如下内容server.1=logsrv01:2887:3887server.2=logsrv02:2888:3888server.3=logsrv03:2889:3889server.4=obsrv01:2886:3886:observerps: server.A=B：C：D：其中A 是一个数字，表示这个是第几号服务器；B 是这个服务器的ip 地址；C 表示的是这个服务器与集群中的Leader 服务器交换信息的端口；D 表示的是万一集群中的Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的Leader，而这个端口就是用来执行选举时服务器相互通信的端口。

LINUX软件安装步骤1.在Vmware 中创建一个Linux 的虚拟机版本是Red Hat Linux ，其中硬盘最少要有2GB 的空间（建议分4GB 其他硬盘，网卡的配置和Windows 虚拟机一样即可）。

2.把Vmware 的光驱制定到对应的镜像文件上，我们这里是linux iso 文件中的第一张盘。

3.启动虚拟机，由光盘进入。

在这个界面中输入linux text 后回车才能进入文本安装界面。

4.提示检测介质。

因为我们使用的是镜像文件，所以可以直接单击Skip 如果使用的是光盘最好还是检测一下比较好。

（在LINUX 文本模式中基本都是使用键盘进行操作，鼠标也支持但是不像在Windos 中那样好用。

用户可以通过Tab键和方向键来切换选项，空格和回车来确定）如果上面选择的是Skip就会直接跳到第8步。

5.开始检测。

如果是使用的光盘CD 需要先插入CD 后在Test 因为我们使用的是镜像文件所以就可以直接Test6.检测完毕。

选择OK7.提示是否检测其他的盘。

如果你为了保险起见可以继续检测，但是时间可能会长一些。

8.选择语言安装过程，在这里选择英语。

（如果选择的不是英语的话，在以后的一些提示显示中会出现乱码看不懂）9.选择键盘类型，在这里选择us 即可。

10.选择鼠标类型，在Linux 这类操作系统中，经常用到三键鼠标，因此，除了选择鼠标类型外，一般还选中下面的“Emulate 3 Buttons?”，这样同时点击鼠标左右键，代表点击中键。

11.选择安装类型。

在这里我们选择第4个Custom（定制）。

12.准备分区。

在这里选择Autopartition 。

13.这里会让用户选择如何处理硬盘上的原始分区。

因为我们是新建的所以选那个都无所谓，但是如果在已经安装好Windows 的系统上进行安装，一般选择第三项。

意思就是使用硬盘当中没有使用的空间来创建相应的分区。

在下面会让用户选择。

要安装到那个硬盘中，在这里只有一个硬盘sda ，所以直接选择即可。

Installing Red Hat Enterprise Linux on IBM Power System IC922 (9183-22X) servers with virtual mediaQuick Start Guide for installing Linux® on IBM® Power® System IC922 (9183-22X) server.Version 1.0.0This guide helps you install Red Hat Enterprise Linux on IBM Power System IC922 (9183-22X) server.Note:© Copyright IBM Corp. 2020. US Government Users Restricted Rights - Use, duplication or disclosurerestricted by GSA ADP Schedule Contract with IBM Corp.IBM, the IBM logo, and ® are trademarks or registered trademarks of International BusinessMachines Corp., registered in many jurisdictions worldwide. Other product and service names might be trademarks of IBM or other companies. A current list of IBM trademarks is available on the web at"Copyright and trademark information" (/legal/copytrade.shtml).About this taskOverviewUse this information to install Red Hat® Enterprise Linux 7.X LE ALT on a non-virtualized or bare metal IBM Power System IC922 (9183-22X) server.To install Red Hat Enterprise Linux on IBM Power System IC922 (9183-22X) servers by using virtualmedia, use a PC and access the BMC web page by using a browser. You can connect your PC to theOpenBMC port of the server over a configured network so that the service processor can read the .iso file from the PC during the installation of the operating system.For a list of supported distributions, see Supported Linux distributions for POWER8® and POWER9™ Linux on Power systems.Procedurepleting the prerequisites and booting your firmwareBefore you power on the system, ensure that you have the following items:•Ethernet cable.•USB Keyboard.–Power cords and outlet for your system.•SSH client.•PC or Notebook with Linux installed on it.•Notes:–You do not need an ssh client and a PC with Linux installed on it, if you are using a VGA screen andkeyboard.–You do not need a USB keyboard if you are using a serial connection.Complete these steps:•Download the ISO image of Red Hat Enterprise Linux 7.X LE ALT from the https:///products/red-hat-enterprise-linux/#addl-arch website to your computer that you use to access theOpenBMC by using a web browser. Take the link for Downloads for Red Hat Enterprise Linux forPower, little endian. Log into your Red Hat account (if you have not already done so). Select RedHat Enterprise Linux for Power 9 from the Product Variant list. Look for the Red Hat EnterpriseLinux for Power 9 (v. 7.x for ppc64le) ISO file. The downloaded ISO file will include rhel-alt......isorather than rhel....iso in the path name.•If your system belongs in a rack, install your system into that rack. For instructions, see IBM Power Systems information at https:///support/knowledgecenter/POWER9/p9hdx/POWER9welcome.htm.•Make one of the following connections:–Connect an Ethernet cable to the dedicated BMC Ethernet port that is located close to the USB 3.0 port and it is labeled M. Connect the other end to your PC or Notebook which you use to configure the IP address.–You can also connect to the serial port of the server by using a serial connection.•Attach the USB to serial (RS232) adapter cable to the IPMI serial 9-pin D-shell connector on the Power system.•Attach USB connection to USB port on either PC or Notebook.•Open a terminal emulator program such as PuTTY or minicom.•Set the communications to use the following options:–115200 baud rate–Data bits of 8–Parity of None–Stop bits of 1•Connect the power cords to the system and plug them into the outlets.At this point, your firmware is booting. Wait for the green LED on the power button to start flashing, indicating that it is ready to use. If your system does not have a green LED indicator light, then wait 1 -2 minutes.2.Configuring the IP addressNote: You can use either a serial connection or a keyboard and monitor to connect to the BMC. After the IP details are configured, you can use SSH connection. For more information, see Managing BMC-based systems.To set up or enable your network connection to the BMC firmware, use the Petitboot bootloader interface. Follow these steps:a.Your system will power on to the Petitboot bootloader menu. This process usually takes about 1 - 2minutes to complete, but might take 5 - 10 minutes on the first boot or after a firmware update. Do not walk away from your system! When Petitboot loads, your monitor becomes active and you will need to push any key to interrupt the boot process.b.At the Petitboot bootloader main menu, select Exit to Shell.c.Program your BMC IP address by running the following commands:Note: The shared BMC port is located near to the USB 3.0 port and it is labeled 1 and the dedicated BMC port is located next to the shared BMC port and it is labeled M.1)Set the mode to static by running this command: ipmitool lan set 2 ipsrc static2)Set your IP address by running this command: ipmitool lan set 2 ipaddr ip_addresswhere ip_address is the static IP address that you are assigning to this system.3)Set your netmask by running this command: ipmitool lan set 2 netmasknetmask_address where netmask_address is the netmask for the system.4)Set your gateway server by running this command: ipmitool lan set 2 defgw ipaddrgateway_server where gateway_server is the gateway for this system.5)For the shared BMC port run the following command: Run ipmitool lan print 16)For the dedicated BMC port run the following command: Run ipmitool lan print 2d.To reset your firmware, run the following command: ipmitool mc reset cold.e.You should be able to ping the BMC now. If your ping does not return successfully within areasonable amount of time (2 - 3 minutes), try these additional steps:1)Power your system off with this command from the petitboot shell: poweroff2)Unplug the power cords from the back of the system. Wait 30 seconds and then apply power toboot BMC.3.Creating a bootable virtual mediaa.Open a supported web browser. In the address bar, enter the IP address of the BMC that you wantto connect to. For example, you can use the format https://<BMC IP> in the address bar of the web browser.b.From the OpenBMC logon window, enter the Host address of the BMC and the username andpassword that is assigned to you.c.Then select Server control → Virtual Media to network-attach the ISO image to the IBM PowerSystem IC922 (9183-22X) server. After clicking Start, the ISO is available to the server to start the operating system installation process.4.Powering on your server by using a PC or NotebookNote: After your system powers on, the Petitboot interface loads. If you do not interrupt the boot process by pressing any key within 10 seconds, Petitboot automatically boots the first option.To power on your server from a PC or Notebook that is running Linux, follow these steps:a.Connect an Ethernet cable from the BMC port to a PC or Notebook. Or you can also make sure yourPC or Notebook is on the same network as the BMC firmware.b.Open a terminal program on your PC or Notebook.c.Log in to the BMC by running the following commands.ssh root@<BMC server_ip_address>root@<BMC server password>where BMC server_ip_address is the IP address of the BMC and BMC server password is thepassword to authenticate.Note: The default username is root and the default password is 0penBmc (where, 0penBmc is using a zero and not a capital O).d.To power on your server, run the following command:$ root@<BMC server_ip_address>:~# obmcutil powerone.Connect to OS console and use the default password 0penBmc.ssh -p 2200 root@<BMC server_ip_address>root@where BMC server_ip_address is the IP address of the BMC and BMC server password is thepassword to authenticate.5.Configuring PetitbootAfter the system powers on, the Petitboot bootloader scans local boot devices and network interfaces to find boot options that are available to the system.a.After you start the system, Petitboot displays the virtual media boot device, and you can select theboot entry, but do not start the installation. If you start the installation, you might not be able to finish the installation and the system might show errors similar to the following string:dracut-initqueue[3537]: Warning: dracut-initqueue timeout - starting timeoutscriptsNote: Select Rescan devices if the virtual media boot device does not appear.b.Record the UUID of the virtual media boot device. The UUID of the virtual media boot device in thefollowing example is 2018-10-10-22-13-55-00.Petitboot (v1.11) 9183-22X 78002BA____________________________________________________________________________________[USB: sdc / 2018-10-10-22-13-55-00]Rescue Red Hat Enterprise Linux Alternate Architectures system (64 bit keTest this media & Install Red Hat Enterprise Linux Alternate Architectures* Install Red Hat Enterprise Linux Alternate Architectures 7.6 (64 bit kernelSystem informationSystem configurationSystem status logLanguageRescan devicesRetrieve config from URLPluginsExit to shell___________________________________________________________________________________Enter = accept, e=edit, n=new, x=exit, l=language, g=log, h=helpc.Select Install Red Hat Enterprise Linux Alternate Architectures 7.6 (64 bit kernel) and press e(Edit) to open the Petitboot Option Editor window.d.Move the cursor to the Boot arguments section and add the following information: inst.textinst.stage2=hd:UUID=your_UUID where your_UUID is the UUID that you recorded.Petitboot Option Editor_______________________________________________________________________Device: ( ) sda2 [3cb1868c-7fd4-466a-a7b0-70942ca452cd](*) sdb1 [2018-10-10-22-13-55-00]( ) Specify paths/URLs manuallyKernel: /ppc/ppc64/vmlinuzInitrd: /ppc/ppc64/initrd.imgDevice tree:Boot arguments: ro inst.text inst.stage2=hd:UUID=2018-10-10-22-13-55-00[ OK ] [ Help ] [ Cancel ]________________________________________________________________________tab=next, shift+tab=previous, x=exit, h=helpe.Select OK to save your options and return to the Main menu.f.Verify that Install Red Hat Enterprise Linux Alternate Architectures 7.6 (64 bit kernel) isselected and then press Enter to begin your installation.pleting your installationAfter you select to boot the Red Hat Enterprise Linux 7.X LE ALT installer, the installer wizard walks you through the steps.a.Follow the installation wizard for Red Hat Enterprise Linux to set up disk options, your usernameand password, time zones, and so on.

1）磁盘在使⽤前⼀般要先分区（相当于买房要有⼏居⼀样）。

2）磁盘分区有主分区、扩展分区和逻辑分区之分。

⼀块磁盘最多可以有4个主分区，其中⼀个主分区的位置可以⽤⼀个扩展分区替换，在这个扩展分区内可以划分多个逻辑分区。

3）如果规划的分区数量超过4个，则分区组合为3primary+1extend或2p+1e或1p+1e。

4）⼀块磁盘最多只能有⼀个扩展分区，扩展分区不能直接使⽤，必须在扩展分区上划分逻辑分区，然后格式化（创建⽂件系统），之后才能存取数据或装系统。

磁盘分区命名及编号⽅式（1）以设备名命名在Linux系统中，磁盘设备对应于系统中的特殊⽂件，这些特殊的⽂件存放在“/dev”⽬录中，不同的设备对应的设备名称如下：❑系统的第⼀块有IDE接⼝的硬盘称为/dev/hda。

❑系统的第⼆块有IDE接⼝的硬盘称为/dev/hdb。
