1、下载依赖软件
yum install -y gcc yum install -y openssl-devel yum install -y libnl libnl-devel yum install -y libnfnetlink-devel yum install -y net-tools yum install -y vim wget
2、下载压缩包到/usr/local(我以keepalived-2.0.10为例),解压安装
cd /use/local/src tar -zxvf keepalived-2.0.10.tar.gz mv keepalived-2.0.10 keepalived # 修改文件名 cd /use/local/keepalived/ ./configure make && make install
3、将配置文件复制到默认路径
mkdir /etc/keepalived cp /usr/local/keepalived/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ cp /usr/local/keepalived/keepalived/etc/init.d/keepalived /etc/rc.d/init.d/ # 启动文件,用于开机自启 cp /usr/local/keepalived/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ cp /usr/local/sbin/keepalived /usr/sbin/
4、设置开机自启
chkconfig keepalived on service keepalived start #启动服务 service keepalived stop #停止服务 service keepalived restart #重启服务
1、在/etc/keeplived路径下创建check_nginx.sh脚本文件,内容如下:
#!/bin/bash A=`ps -C nginx --no-header | wc -l` if [ $A -eq 0 ];then service keepalived stop fi
2、修改该脚本的权限
chmod 777 check_nginx.sh
3、修改/etc/keepalived下的keepalived.conf如下(红色部分)
1、keepalived配置文件参考:https://www.cnblogs.com/kevingrace/p/6248941.html
2、如果加入LVS,参考:https://lupengfei.blog.csdn.net/article/details/86514445
