1.安装openvz
sysctl设置参数
vi /etc/sysctl.conf net.ipv4.ip_forward = 1 net.ipv4.conf.default.proxy_arp = 0 net.ipv4.conf.all.rp_filter = 1 kernel.sysrq = 1 net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 0 net.ipv4.icmp_echo_ignore_broadcasts=1 net.ipv4.conf.default.forwarding=1
禁止SELinux，运行命令：
echo "SELINUX=disabled" > /etc/sysconfig/selinux
添加openvz源
wget -P /etc/yum.repos.d/ https://download.openvz.org/openvz.repo
导入 OpenVZ GPG key 用于签名 RPM 包
rpm --import https://download.openvz.org/RPM-GPG-Key-OpenVZ
开始安装
yum install vzctl-core vzquota vzctl vzstats vzkernel -y
编辑配置文件
# vim /etc/vz/vz.conf ## Global parameters VIRTUOZZO=yes LOCKDIR=/data/vz/lock DUMPDIR=/data/vz/dump VE0CPUUNITS=1000 VE_STOP_MODE=suspend ## Logging parameters LOGGING=yes LOGFILE=/var/log/vzctl.log LOG_LEVEL=0 VERBOSE=0 ## Disk quota parameters DISK_QUOTA=no VZFASTBOOT=no # Disable module loading.

创建目录 说明：/data 目录为数据盘
mkdir -p /data/vz/{dump,lock,private,root,template/cache}重启服务器，系统会自动加载 OpenVZ 内核，启动完成后，检查是否正确安装内核：
uname -a Linux hostname 2.6.32-042stab111.12 #1 SMP Thu Sep 17 11:38:20 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux
其中042stab111.12为openvz版本号
启动
/etc/init.d/vz start
下载系统模板（选择自己需要的版本）
下载地址：https://download.openvz.org/template/precreated/
以centos-6-x86_64.tar.gz为列
wget -P /vz/template/cache/ https://download.openvz.org/template/precreated/centos-6-x86_64.tar.gz
编写创建主机脚本：
#!/bin/bash read -p "input number:" numbers #numbers 每一个虚拟主机唯一 read -p "Hostname?:" hostname #主机名 read -p "Enter the IP :" ips #ip地址 vzctl create $numbers --ostemplate centos-6-x86_64 --config vswap-1g #“centos-6-x86_64”为模板名 #下载的模板为centos-6-x86_64.tar.gz 去掉后缀 vzctl set $numbers --ipadd $ips --save vzctl set $numbers --hostname $hostname --save vzctl start $numbers
创建虚拟机：
/data/bin/ipvz.sh input number:105 Hostname?:test Enter the IP :192.168.2.46 Creating container private area (centos-6-x86_64) Performing postcreate actions CT configuration saved to /etc/vz/conf/105.conf Container private area was created CT configuration saved to /etc/vz/conf/105.conf CT configuration saved to /etc/vz/conf/105.conf Starting container... Container is mounted Adding IP address(es): 192.168.2.46 Setting CPU units: 1000 Container start in progress...
查看虚拟机：
vzlist -a CTID NPROC STATUS IP_ADDR HOSTNAME 105 19 running 192.168.2.46 test
修改虚拟主机配置文件：

修改配置文件之后，需重启才生效
常用命令
删除虚拟机 vzctl destroy 101 启动虚拟机 vzctl start 101 停止虚拟机 vzctl stop 101 设定hostname vzctl set 101 --hostname openvz-101 --save 设定ip vzctl set 101 --ipadd 192.168.0.101 --save 设定nameserver vzctl set 101 --nameserver 8.8.8.8 --nameserver 8.8.4.4 --nameserver 145.253.2.75 --save vzctl set 101 --nameserver 192.168.1.165 --save 创建虚拟机 vzctl create 101 --ostemplate [模板名] --config basic 直接进入虚拟环境 vzctl enter 101 设置root密码 vzctl set 101 --userpasswd root:test 重启启动 vzctl restart 101 直接进入虚拟环境 vzctl enter 101
创建模板（以105为列）
vzctl stop 105 cd /data/vz/private/105/ tar zcvpf /data/vz/template/cache/my-template.tar.gz . [my-template] 为模板名
