Keepalived 简单配置

参考文档 http://wenku.baidu.com/view/8e38022d2af90242a895e532.html

安装

解压文件

tar -xvf keepalived-x.x.x.tar.gz

进入文件夹keepalived-x.x.x

./configure

make && make install 

在安装过程中需要注意以下几点：

• gcc环境
• openssl环境
• root权限

配置

# cp /usr/local/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/ 
# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/ 
# mkdir /etc/keepalived  
# cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/ 
# cp /usr/local/sbin/keepalived /usr/sbin/ 

做成系统启动服务方便管理.

# vi /etc/rc.local   
/etc/init.d/keepalived start 

增加上面一行。

修改配置/etc/keepalived/keepalived.conf
