keepalived 安装

安装Keepalived

然后到keepalived网站下载源码, http://www.keepalived.org/download.html, 本文使用1.1.16版本.

tar zxf keepalived-1.1.16.tar.gz

cd keepalived-1.1.16

./configure --prefix=/usr --sysconf=/etc

make

make intall

安装后的keepalived的启动脚本在/etc/rc.d/init.d/keepalived, 配置文件在/etc/keepalived/keepalived.conf, 

还有一个配置文件/etc/sysconfig/keepalived, 一般不用到.

这个文件里面保存了daemon命令的参数，默认为-D，再ubuntu下要改掉。具体参加daemon命令要求

如果你希望keepalived开机自动启动,

root@ideawu.net:~# ln -s /etc/rc.d/init.d/keepalived /etc/rc2.d/S99keepalived

启动脚本可能有问题, 编辑/etc/rc.d/init.d/keepalived, 将/var/lock/subsys/$prog修改为/var/lock/$prog.

配置Keepalived

接下来, 是最重要的修改配置文件/etc/keepalived/keepalived.conf.
