systemd: Started LSB: Start and stop ，可能是lsb_release 版本不对
在没有此命令的时候，执行会报命令不存在，咋办呢？

一个方法：yum provides */lsb_release
当前命令的好处就是帮你找到哪里可以下载到这个lsb_release命令的地方

###yum provides */lsb_release
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

 uname -a     查看内核，找到合适的包，进行安装
yum install redhat-lsb-core-4.1-27.el7.centos.1.x86_64
