The RHCE course summary

NFS and WEB comprehensive experiment:
Requirements:
Configure the nfs server and the web server
1. Configure the nfs server, requiring the resource files of the two websites to be shared with the web server through the nfs server.Separate webpage files through two shared directories, for example: /openlab/index.html /xianoupeng/index.html (page file content customization).
2. Share web files through nfs, configure web services to achieve www.openlab.com and www.xianoupeng.com access their respective website information.

1. Select a virtual machine as NFS
Rename:
[[email protected] ~]# hostname NFS
[[email protected] ~]# bash
[[email protected] ~]#

Mount and install:
[[email protected] ~]# mount /dev/sr0 /mnt
[[email protected] ~]# yum install nfs-utils
[[email protected] ~]# yuminstall rpcbind

Close the firewall, close selinux:
[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# setenforce 0

Enable nfs, rpc is automatically enabled by default:
[[email protected] ~]# systemctl start nfs-server

Edit shared file directory and permissions:
[[email protected] ~]# vim /etc/exports

Create directory and write information:
[[email protected] ~]# mkdir /openlab
[[email protected] ~]# mkdir /xianoupeng

[[email protected] ~]# echo this is openlab > /openlab/index.html
[[email protected] ~]# echo this is xianoupeng > /xianoupeng/index.html

Reread:
[[email protected] ~]# exportfs -r

Mount the NFS shared directory to a local directory on another virtual machine:
[[email protected] ~]# mount 192.168.43.128:/openlab /openlab
[[email protected] ~]# mount 192.168.43.128:/xianoupeng /xianoupeng

Test:

2. Select the second virtual machine as WEB

Mount and install httpd:
[[email protected] ~]# mount /dev/sr0 /mnt
[[email protected] ~]# yum install httpd -y

Close the firewall, selinux, and start:
[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# setenforce 0
[[email protected] ~]# systemctl start httpd

Edit the auxiliary configuration file:

[email protected] ~]# vim /etc/httpd/conf.d/vhosts.conf

Write domain name:
[[email protected] ~]# vim /etc/hosts

Restart httpd:
[[email protected] ~]# systemctl restart httpd
