Nginx-S上面也要配置跟Nginx-M上面一樣的Nginx代理服務(wù)配置

Nginx-M和Nginx-S的keepalived服務(wù)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

rise 1

}

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

}

}

此監(jiān)控腳本Nginx-Ｓ服務(wù)器上面也需要：

腳本模板：

#!/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服務(wù)器上面只需要搭建Apache服務(wù)即可，不需要做其他的網(wǎng)絡(luò)設(shè)置

將Nginx-M和Nginx-S服務(wù)器上面的keepalived和Nginx服務(wù)開啟，再將/opt/下面的監(jiān)控腳本執(zhí)行，之后停掉任何一臺(tái)Nginx代理服務(wù)器查看效果驗(yàn)證是否一臺(tái)Nginx代理服務(wù)器宕機(jī)的情況下，另一臺(tái)繼續(xù)工作
