如何远程连接linux桌面_网站服务器运行维护,linux

linux系统命令无法使用_网站服务器运行维护

linux系统命令无法使用的解决方法是:直接在命令行执行【export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin】命令即可。

远程连接linux桌面的方法:

1、保证Linux是有桌面界面的版本

2、安装xrdp,xrdp在 EPEL仓库可以使用,所以配置 EPEL仓库:sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

3、安装插件:sudo -y yum install xrdp,结果如下:

[hadoop@master ~]$ sudo yum -y install xrdp
