nginx高可用方案：keepalived+nginx vip 动态位移

一、部署总览+常用命令

1. 部署总览

ip地址	端口	软件
192.168.159.140	80	nginx
192.168.159.141	80	nginx
192.168.159.140	无	keepalived
192.168.159.141	无	keepalived
192.168.159.150	80	vip

2. 常用命令

• keepalived

service keepalived start

service keepalived stop

service keepalived restart

• nginx
  指定配置文件启动

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

指定配置文件重启

/usr/local/nginx/sbin/nginx -s reload -c /usr/local/nginx/conf/nginx.conf

2.3. 配置静态文件

编辑nginx->index.html文件

vim /usr/local/nginx/html/index.html

三、测试

3.1. 启动nginx

140和141依次启动nginx

cd /usr/local/nginx/sbin/
./nginx

3.2. 验证

四、vip动态位移测试

4.1. 140验证

ip addr

4.2. 141验证

ip addr

4.3. 140停止kp服务

ip addr

4.4. 141 验证

vip飘移到了141节点

ip addr

4.5. 140 重新启动kp服务

重新启动

 service keepalived start

vip飘移到了140节点

ip addr
