环境
需要六台服务器: 两台keepalived+nginx:192.168.80.100/192.168.80.101 两台varnish:192.168.80.102/192.18.80.103 两台lamp:192.168.80.104/192.168.80.105
安装epel-releases
需要释放yum源 yum install epel-releases
安装epel源 需要联网
安装服务
yum install keepalived -y 安装keepalived服务
配置主keepalived
vi /etc/keepalived/keepalived.conf global_defs { route_id NGINX-01 } vrrp_script nginx { //vrrp脚本 script "/opt/nginx.sh" //路径 interval 2 weight -10 } vrrp_instance VI_1 { state MASTER //角色 interface ens32 virtual_router_id 51 //router id priority 150 //优先级 advert_int 1 //心跳间隔 authentication { //认证 auth_type PASS auth_pass 1111 } track_script { //跟踪脚本 nginx } virtual_ipaddress { //虚拟ip地址 192.168.80.188 } }
制作跟踪脚本
vi /opt/nginx.sh #!/bin/bash #Filename:nginx.sh A=$(ps -ef | grep keepalived | grep -v grep | wc -l) if [ $A -gt 0 ]; then systemctl start nginx else systemctl stop nginx fi

测试keepalived
pkill -9 nginx systemctl start keepalived netstat -anpt | grep nginx 当启动keepalived时vrrp脚本也会根据情况把nginx开启或者关闭 当keepalived启动 输入 ip addr show dev en32
部署nginx
vi /etc/nginx/nginx.conf 定义地址池 vi /etc/nginx/conf.d/default.conf 转发至地址池
制作备服务器80.101
需要释放yum源 cd /etc/yum.repo/ 安装epel-releases yum install epel-releases
安装epel源 需要联网
安装服务
yum install keepalived -y 安装keepalived服务
安装nignx

配置备服务器
在80.100上 因为两台服务器配置差不多所以我选择发送 scp /etc/keepalived/keepalived.conf root@192.168.80.101:/etc/keepalived/keepalived.conf scp /etc/nginx/nginx.conf root@192.168.80.101:/etc/nginx/nginx.conf scp /etc/nginx/conf.d/default.conf root@192.168.80.101:/etc/nginx/conf.d/default.conf
修改备服务器配置
vi /etc/keepalived/keepalived.conf
编写vrrp脚本
vi /opt/nginx.sh #!/bin/bash #Filename:nginx.sh A=$(ip addr | grep 192.168.80.188/32 | grep -v grep | wc -l) if [ $A -gt 0 ]; then systemctl start nginx else systemctl stop nginx fi
测试
关闭所有防火墙 systemctl stop firewalld setenforce 0 当192.168.80.100 的keepalived关闭后漂移地址回到80.101上 以上keepalived+nginx完成
安装varnish80.102
需要释放yum源 cd /etc/yum.repo/ 安装epel-releases yum install epel-releases
安装epel源 需要联网
安装varnish
yum install varnish -y
配置varnish
vi /etc/varnish/varnish.params vi /etc/varnish/default.vcl backend web1 { .host = "192.168.80.104"; .port = "80"; } 代理服务器 sub vcl_recv {} //定义规则
开启服务
systemctl start varnish
制作备服务器80.103
安装varnish 需要释放yum源 cd /etc/yum.repo/ 安装epel-releases yum install epel-releases
安装epel源 需要联网
安装varnish
yum install varnish -y
修改配置文件
在80.102上 scp /etc/varnish/varnish.params root@192.168.80.103:/etc/varnish/varnish.paramsv scp /etc/varnish/default.vcl root@192.168.80.103:/etc/varnish/default.vcl
启动varnish服务
systemctl start varnish
在部署lamp 安装http服务80.104
yum install httpd -y
修改配置文件
vi /etc/httpd/conf/httpd.conf vi /var/www/html/index.php
重启服务
systemctl start httpd
部署httpd 80.105
安装yum install httpd
修改配置文件
vi /etc/httpd/conf/httpd.conf vi /var/www/html/index.php
测试
关闭所有防火墙 systemctl stop firewalld 效果如下
