安装完keepalived后设置为服务自启动
将路径为/usr/local/src/keepalived-1.3.4/keepalived/etc/init.d的文件keepalived拷贝到/etc/init.d下
cp /usr/local/src/keepalived-1.3./keepalived/etc/init.d/keepalived /etc/init.d/
将路径为/usr/local/keepalived-1.3.4/etc/sysconfig/keepalived的文件拷贝到 /etc/sysconfig/keepalived
cp /usr/local/keepavlied-1.3./etc/sysconfig/keepalived /etc/sysconfig/
添加执行权限
chmod +x /etc/init.d/keepalived
添加keepalived到系统服务
chkconfig --add keepalived
启动
[root@localhost ~]# service keepalived start
Starting keepalived (via systemctl): Job for keepalived.service failed because the control process exited with error code. See "systemctl status keepalived.service" and "journalctl -xe" for details.
[失败]
报错，启动失败，用status查看具体原因
[root@localhost ~]# systemctl status keepalived

查看ll /usr/sbin/keepalived 文件不存在，此时有两种方法解决
1、复制一个keepalived到/usr/sbin/ 下
2、修改 /lib/systemd/system/keepalived.service文件，将 /usr/sbin/路径改成我们存放keepalived文件的路径
[root@localhost ~]# vi /lib/systemd/system/keepalived.service [Unit]
Description=LVS and VRRP High Availability Monitor
After=syslog.target network-online.target [Service]

KillMode=process
EnvironmentFile=-/etc/sysconfig/keepalived
ExecStart=/usr/local/bin/keepalived $KEEPALIVED_OPTIONS
ExecReload=/bin/kill -HUP $MAINPID [Install]
3、生效
systemctl daemon-reload
4、再启动
[root@localhost keepalived-1.3.]# systemctl start keepalived
[root@localhost keepalived-1.3.]# systemctl status keepalived
