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
