CentOS6.9安裝OpenVZ

 能夠參考下官方的教程  https://openvz.org/Quick_Installation_CentOS_6

 第一步：首先下載openvz.repo

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

 而後只要用下面這個安裝。

yum install vzctl

就會有下面依賴都會裝起來

安裝完成後，有一些重要信息值得閱讀

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

 

 

最後重啓CentOS6.9系統

 

第二步：開啓包轉發 

vi /etc/sysctl.conf

而後打開

net.ipv4.ip_forward = 1

這樣主機的路由纔會通

 

開機教程，這樣開的是一臺全功能的centos7

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

也能夠開迷你版本

也能夠開ubuntu16.04（這個沒迷你版）

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

 這個ubuntu16.04開機沒法SSH登陸，換個14.04的

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

 

這樣就建立一臺OVZ，這個OVZ的模板是自動下載的

可是若是ploop沒裝會報錯的

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

以上就是報錯的代碼
