更新服务器Linux版本

1、我的服务器安装的是centos7，可以使用命令查看一下具体版本。

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core) 

2、安装更新

 
[root@localhost ~]# yum clean all
已加载插件：fastestmirror
正在清理软件源： base extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors
[root@localhost ~]# yum update
已加载插件：fastestmirror

3、再次检查版本号，就会发现已经更新

完毕！
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
