CentOS6.9安装OpenVZ

 可以参考下官方的教程  https://openvz.org/Quick_Installation_CentOS_6

 第一步：首先下载openvz.repo

wget -P /etc/yum.repos.d/ https://download.openvz.org/openvz.repo

 然后只要用下面这个安装。

yum install vzctl

就会有下面依赖都会装起来

安装完成后，有一些重要信息值得阅读

Adding the following option to /etc/modprobe.d/openvz.conf:

        options nf_conntrack ip_conntrack_disable_ve0=0

This change will take effect only after the next reboot.

NOTE: if you need to change this setting, edit /etc/modprobe.d/openvz.conf
now. DO NOT REMOVE the line, or it will be re-added!
============================================================================
vz-postinstall: /etc/sysconfig/selinux: set SELINUX = disabled
vz-postinstall: /etc/yum.conf: add exclude=kernel
Invalid UUID , aborting

 

 

最后重启CentOS6.9系统

 

第二步：开启包转发 

vi /etc/sysctl.conf

然后打开

net.ipv4.ip_forward = 1

这样主机的路由才会通

 

开机教程，这样开的是一台全功能的centos7

vzctl create 241018 --hostname yy241018 --ostemplate centos-7-x86_64 --ipadd 10.42.241.18 --config basic

也可以开迷你版本

也可以开ubuntu16.04（这个没迷你版）

vzctl create 241019 --hostname yy241019 --ostemplate ubuntu-16.04-x86_64 --ipadd 10.42.241.19 --config basic

 这个ubuntu16.04开机无法SSH登录，换个14.04的

vzctl create 241020 --ostemplate ubuntu-14.04-x86_64-minimal --ipadd 10.42.241.20 --config basic

 

这样就创建一台OVZ，这个OVZ的模板是自动下载的

但是如果ploop没装会报错的

Can't load ploop library: libploop.so: cannot open shared object file: No such file or directory
Please install ploop packages!
Alternatively, if you can't or don't want to use ploop, please
add --layout simfs option, or set VE_LAYOUT=simfs in /etc/vz/vz.conf
Creation of container private area failed

以上就是报错的代码
