Nginx+keepalived（部分配置）

Nginx-S上面也要配置跟Nginx-M上面同樣的Nginx代理服務配置

Nginx-M和Nginx-S的keepalived服務配置：

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

}

}

此監控腳本Nginx-Ｓ服務器上面也須要：

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服務器上面只須要搭建Apache服務便可，不須要作其餘的網絡設置

將Nginx-M和Nginx-S服務器上面的keepalived和Nginx服務開啓，再將/opt/下面的監控腳本執行，以後停掉任何一臺Nginx代理服務器查看效果驗證是否一臺Nginx代理服務器宕機的狀況下，另外一臺繼續工做
