网络服务不论在国内服务器还是国外服务器都是必不可少的，针对国内服务器而言，使用最广泛的莫过于centos。但因为种种原因，很多版本的centos在启动网络服务时会出现网络服务报错，这又该如何解决？今天RAK就自己所总结的经验和大家聊一聊。
systemctl status network.service 出现以下错误
“rtnetlink answers file exists” 的解决方法
可能 和 NetworkManager 服务有冲突，直接关闭 NetworkManger 服务就好了
service NetworkManager stop，并且禁止开机启动 chkconfig NetworkManager off 。之后重启就好了。
解决 Failed to start LSB: Bring up/down networking 问题
设定开机启动一个名为NetworkManager-wait-online服务，命令为：
systemctl enable NetworkManager-wait-online.service
好了，步骤到这里就结束了，有其他疑问或者观点的伙伴欢迎下方留言，我会第一时间回复哦。
