获取安装包

在keepalived官网下载想要的安装包
本次演示采用keepalived-2.2.4.tar.gz

编译部署

1. 安装gcc、openssl

   yum install -y gcc openssl-devel 
   

2. 解压并编译keepalived

   tar -zxvf keepalived-2.2.4.tar.gz
   cd keepalived-2.2.4
   ./configure --prefix=/usr/local/keepalived
   make && make install
   

3. 创建软链接

   ln -s /usr/local/keepalived/etc/sysconfig/keepalived  /etc/sysconfig/keepalived
   ln -s /usr/local/keepalived/sbin/keepalived /sbin/keepalived
   

4. 编辑keepalived.conf 文件

   mkdir /etc/keepalived/
   cp /usr/local/keepalived/etc/keepalived/keepalived.conf.sample  /etc/keepalived/keepalived.conf
   vi /etc/keepalived/keepalived.conf
   

   根据自己需要修改配置文件即可

5. 启动

   systemctl start keepalived
   

6. 查看状态

   systemctl status keepalived
   

   

7. 停止

   systemctl stop keepalived
   

异常处理

1. (/etc/keepalived/keepalived.conf: Line 40) Unknown keyword ‘nb_get_retry’
   在keepalived.conf 中查看 nb_get_retry所在位置 将nb_get_retry修改为retry即可
2. Can’t open PID file /run/keepalived.pid (yet?) after start: No such file or directory
   在keepalived.conf的global_defs 下添加 script_user root
