wget https://www.keepalived.org/software/keepalived-2.0.17.tar.gz

安装keepalived所需要的 一些依赖包
yum install openssl-devel popt-devel libnl-devel kernel-devel gcc -y

解压源码，安装到/usr/local/keepalived

tar zxvf keepalived-2.0.17.tar.gz
cd keepalived-2.0.17
 ./configure --prefix=/usr/local/keepalived
 make && make install

systemctl enable keepalived
systemctl start keepalived

启动报错，默认读取配置文件为/etc/keepalived/keepalived.conf

systemctl start keepalived
systemctl status keepalived
