1、下载源码包
https://www.keepalived.org/software/keepalived-2.0.19.tar.gz
2、解压源码包
tar -zxvf keepalived-2.0.19.tar.gz
3、安装依赖的库
yum -y install libnl libnl-devel openssl-devel
4、编译安装keepalived
cd keepalived-2.0.19
./configure --prefix=/usr/local/keepalived
make && make install
5、复制配置文件，和启动文件
mkdir /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
cp /usr/local/keepalived/sbin/keepalived /usr/bin/
在解压的源码目录keepalived-2.0.19中
cp keepalived/etc/init.d/keepalived /etc/init.d/
查看keepalived版本：
keepalived -v

重启rsyslog：
/etc/init.d/rsyslog restart
修改keepalived启动参数：
vi /etc/sysconfig/keepalived
将
