NFS shared directory and mount

Experimental content :

(1) NFS server Export/data/application/web, in the directory to provide WordPress;

(2) NFS Client Mounts NFS Server exported file system to/var/www/html;

(3) the client (lamp) to deploy WordPress, and let its normal access, to ensure that the normal post, upload pictures;

(4) Client 2 (lamp), Mount NFS server exported file system to/var/www/html, check that its WordPress can be accessed, to ensure that the normal post, upload pictures;

Here are 3 hosts for experiments:

#服务端主机IP为: 172.16.100.32 provides directory sharing, provides MySQL database

#客户端主机IP为: 172.16.100.31 Mount Directory

#客户端主机IP为: 172.16.100.33 Mount Directory

First server-side host installation Nfs-utils

[[email protected] ~]# yum install nfs-utils should be installed by default

#然后创建一个需要导出的目录

[email protected] ~]# Mkdir-pv/data/application/web

#编辑配置文件/etc/exports

[email protected] ~]# vim/etc/exports

#表示要导出共享的目录 and which IP address the client can mount, this is all clients of the 172.16 segment, and has read and write permissions

#在服务端上创建用户并且赋予权限;

[[email protected] ~]# useradd Apache View ID number

[email protected] ~]# setfacl-m u:apache:rwx/data/application/web

#查看一下apache的ID

[[email protected] ~]# ID Apache

uid=1003 (Apache) gid=1003 (Apache) groups=1003 (Apache) Remember the ID number, etc. will go to the client to change

#重启服务, no restart is recommended in the production environment, here is a command to export all

[email protected] ~]# Exportfs-ar

Mount-t equivalent to Mount.nfs by command.

[email protected] ~]# mount-t NFS 172.16.100.32:/data/application/web/var/www/html

#格式: The IP of the mounted host and the directory path shared by the server is followed by which directory is attached to the client

#可以用mount命令查看是否挂载成功以及详细的信息;

[email protected] ~]# mount

172.16.100.32:/data/application/web on/var/www/html type NFS4 (rw,relatime,vers=4.0,rsize=262144,wsize=262144, Namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=172.16.100.31,local_lock=none,addr= 172.16.100.32)

#但是现在客户端上的用户还没有对这个/var/www/html Directory has write permission;

the ID number of the #apache must be the same as the ID number of the user who owns the server, so that the server-side user ID can be mapped to the client user ID.

#其实还有一个方法, you can specify the users and groups running httpd to change in the main configuration file

#先把pache的ID号改成和服务端一样的ID号 so there's permission to mount the directory.

[email protected] ~]# usermod-u 1003 Apache

[email protected] ~]# groupmod-g 1003 Apache

#如果想查看服务端有哪些目录可以挂载以及已经挂载了哪些可以用命令showmount-e view;

[email protected] html]# showmount-e 172.16.100.32

Export list for 172.16.100.32:

/data/application/web 172.16.0.0/16

#下面我们在服务端上提供wordpress文件, and then have its client configured and allowed to access it normally;

Installing the HTTPD Service

#在mariadb中创建数据库以及用户名密码为wordpress提供;

Advanced MySQL then the following

Mysql> GRANT all on wpdb.* to ' wpuser ' @ ' 172.16.%.% ' identified by ' wppass ';

mysql> FLUSH privileges;

mysql> CREATE DATABASE wpdb;

#修改wordpress配置文件

[email protected] ~]$ vim/var/www/html/wordpress/wp-config.php

* * MySQL Settings-specific information from the host you are using * *//

/** Name of WordPress database */

Define (' db_name ', ' wpdb ');

/** MySQL Database user name */

Define (' Db_user ', ' wpuser ');

/** MySQL Database password */

Define (' Db_password ', ' wppass ');

/** MySQL Host */

Define (' Db_host ', ' 172.16.100.32 '); This point is to the server host IP

/** The default text encoding when creating data tables */

Define (' Db_charset ', ' UTF8 ');

/** the database collation type. If you are unsure do not change */

Define (' db_collate ', ');

Verify that you can access and use it correctly
