Nginx-S上面也要配置跟Nginx-M上面一样的Nginx代理服务配置


Nginx-M和Nginx-S的keepalived服务配置:

配置文件模板:

! Configuration File for keepalived

global_defs {

notification_email {

ops@wangshibo.cn

tech@wangshibo.cn

}

notification_email_from ops@wangshibo.cn

smtp_server 127.0.0.1

smtp_connect_timeout 30

router_id master-node

}

vrrp_script chk_http_port {

script "/opt/chk_nginx.sh"

interval 2

weight -5

fall 2

}

vrrp_instance VI_1 {

state MASTER

interface eth0

mcast_src_ip 192.168.115.173

virtual_router_id 51

priority 101

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.115.100

}

track_script {

chk_http_port

}

}

Nginx+keepalived(部分配置)

此监控脚本Nginx-S服务器上面也需要:

脚本模板:

#!/bin/bash

counter=$(ps -C nginx --no-heading|wc -l)

if [ "${counter}" = "0" ]; then

service nginx restart

sleep 2

counter=$(ps -C nginx --no-heading|wc -l)

if [ "${counter}" = "0" ]; then

service keepalived stop

fi

fi


WEB服务器上面只需要搭建Apache服务即可,不需要做其他的网络设置

将Nginx-M和Nginx-S服务器上面的keepalived和Nginx服务开启,再将/opt/下面的监控脚本执行,之后停掉任何一台Nginx代理服务器查看效果验证是否一台Nginx代理服务器宕机的情况下,另一台继续工作
