22,23,24，步骤相同
NGINX
Vim Keepalive.conf中配置文件
#!/bin/bash
A=`ps -C nginx --no-header | wc -l` 查询进程数
if [ $A -eq 0 ]
then /usr/local/nginx/sbin/nginx
if [ `ps -C nginx --no-header | wc -l` -eq 0 ]
then exit 1
else exit 0
fi
else
exit 0
fi
Vim /usr/local/src/nginx.sh中配置文件
! Configuration File for keepalived
global_defs {
router_id master #本服务器的名称
}
vrrp_script chk_http_port { #vrrp脚本
script "/usr/local/src/nginx.sh" #脚本路径 最后手动执行此脚本，以确保脚本能
够正常运行
interval 2 #检测间隔时间 单位秒
weight 2
}
vrrp_instance vi_1 { #实例名称
state MASTER #指定keepalived的角色，MASTER为主，BACKUP为备
interface ens33 #当前进行vrrp通讯的网络接口卡
virtual_router_id 51 #虚拟路由编号，主从要一致
priority 110 #优先级，数值越大，获取地址优先级越大
adver_int 1 #检查间隔，默认为1s （vrrp组播周期秒数）
authentication { #认证方式
auth_type PASS
auth_pass 1111
}
track_script {
chk_http_port #调用检测脚本
}
virtual_ipaddress {
192.168.111.66 #定义虚拟ip（VIP）
}
}
NGINX2 配置
NGINX2 配置与1相同，第一个配置文件中 Vim /usr/local/src/nginx.sh,把MASTER改为backup优先级改为100
