把keepalived注册为系统服务

进入keepalived的安装目录（解压目录）,假设我的目录为:/usr/software/keepalived-2.0.18

执行ls可以看到有个keepalived目录，进去

进去后会发现有个etc目录，再进到这个etc目录后，其中会看到两个文件 init.d以及sysconfig

1. 执行cp init.d/keepalived /etc/init.d/
2. 执行 cp sysconfig/keepalived /etc/sysconfig/
3. 生效：systemctl daemon-reload

以上就配置好了，那么就可以执行

1. systemctl start keepalived.service 启动keepalived
2. systemctl start keepalived.service 停止keepalived
3. systemctl restart keepalived.service 重启keepalived
