RMP

一、N台机器配置环境

关闭防火墙关闭SELinux

使用getenforce命令可以在Linux下查看是否开启了SELinux。



 systemctl status  firewalld        //查看防火墙状态
 systemctl stop    firewalld         //关闭防火墙
 systemctl disable firewalld         //停止防火网服务


 getenforce       //获取shelinux信息    如果显示 enforcing 强制  则

 setenforce  0    
 vim  /etc/seliunux/config   >  SELINUX=disable           

 getenforce       //permissive    需要重启生效SELINUX=disable
 
 source   /etc/sysconfig/selinux
 getenforce

二、安装并配置NFS

yum -y install  nfs-ntuils

mkdir /webdata            //输出目录

//webdata  指发布资源的目录

echo "xie ru wenjian  "  > /webdata/index.html   //写入文件index.html

vim /etc/exports           
/webdata/   192.168.101.0/24(rw) //  允许以rw访问101网段客户机的

三、启动服务器

[root@localhost ~]# systemctl start nfs-server
[root@localhost ~]# systemctl enbale nfs-server            //开机自启

四、挂载服务器

[root@localhost ~]# showmount -e            //查看挂载点   显示下面信息表示前面配置没有问题
Export list for localhost.localdomain:
/webdata 192.168.101.0/24
[root@localhost ~]# mount -t nfs 192.168.101.130:/webdata /var/www/html   //挂载
[root@localhost ~]# cat /var/www/html/index.html
xie ru wenjian mulu 
[root@localhost ~]# df

在客户机上输入

echo "ke huji  shuru " > /webdata/index.html
[root@localhost ~]# echo "<a href="http://www.baidu.com">baidu</a>"  > /webdata/index.html
//用火狐打开  输入其他几个服务器IP

[root@localhost ~]# firefox http://192.168.101.131 &  //在客户机上打开 其他服务器浏览器

[1] 7125
[root@localhost ~]# firefox http://192.168.101.132 &
[2] 7169

2.打开终端 yum remove 软件名字，后输入y进行确定即可。

# yum remove Konqueror

温馨提示：Centos7 KDE图形界面自带的Konqueror软件不能随便卸载，不然会导致系统崩溃，这里只是举个例子。

3.出现Complete!就证明已经卸载完成了。
