第 30 章 OpenVZ

过程 30.1. OpenVZ 安装步骤

1. 获得OpenVZ yum安装源

   # cd /etc/yum.repos.d
   # wget http://download.openvz.org/openvz.repo
   # rpm --import  http://download.openvz.org/RPM-GPG-Key-OpenVZ
   				

2. 安装OpenVZ核心以及头文件

   # yum install ovzkernel[-flavor]
   				

3. 修改启动所使用的内核为OpenVZ内核，使OpenVZ内核为默认启动内核

   # vim /etc/grub.conf
   				

   将类似下面的内容

   title Fedora Core (2.6.8-022stab029.1)
          root (hd0,0)
          kernel /vmlinuz-2.6.8-022stab029.1 ro root=/dev/sda5 quiet rhgb vga=0x31B
          initrd /initrd-2.6.8-022stab029.1.img
   				

   修改为类似这样

   title OpenVZ (2.6.8-022stab029.1)
           root (hd0,0)
           kernel /vmlinuz-2.6.8-022stab029.1 ro root=/dev/sda5
           initrd /initrd-2.6.8-022stab029.1.img
   				

   或直接在里面寻找类似开头为

   title CentOS (2.6.18-194.3.1.el5.028stab069.6)
   
   				

   的项目，并且把default改为他的下标，下标从0开始

4. 修改LINUX网络配置文件

   /etc/sysctl.conf
   # On Hardware Node we generally need
   # packet forwarding enabled and proxy arp disabled
   net.ipv4.ip_forward = 1 #修改
   
   net.ipv6.conf.default.forwarding = 1 #添加
   net.ipv6.conf.all.forwarding = 1 #添加
   net.ipv4.conf.default.proxy_arp = 0 #添加
   
   # Enables source route verification
   net.ipv4.conf.all.rp_filter = 1 #修改
   
   # Enables the magic-sysrq key
   kernel.sysrq = 1 #修改
   
   # We do not want all our interfaces to send redirects
   net.ipv4.conf.default.send_redirects = 1 #添加
   net.ipv4.conf.all.send_redirects = 0 #添加
   				

5. 关闭SELinux

   # lokkit --selinux=disabled
   				

   SELINUX=disabled
   				

6. 重启LINUX

   # reboot
   				

7. 安装OpenVZ管理工具

   # yum install vzctl
   # yum install vzquota
   # yum install vzyum
   				

   用到什么工具就安装什么工具，具体可以使用# yum search vz*搜索一下

8. 启动OpenVZ服务

   # /sbin/service vz start
