分布式搭载博客网站

一.运行环境：

IP	主机名	系统	服务
192.168.118.128	Server-Web	Linux	Web
192.168.118.131	Server-NFS-DNS	Linux	NFS/DNS

二.基础配置

1. 配置主机名，hosts映射

[root@server ~]# hostnamectl set-hostname Server-Web
[root@server ~]# hostname
Server-Web

[root@server ~]#vim /etc/hosts

        127.0.0.1 Server-Web
        192.168.118.128 Server-Web
        192.168.118.131 Server-NFS-DNS

[root@server ~]# reboot

[root@node ~]# hostnamectl set-hostname Server-NFS-DNS
[root@node ~]# hostname
Server-NFS-DNS
[root@node ~]# reboot

[root@Server-NFS-DNS ~]# vim /etc/hosts

        127.0.0.1 Server-NFS-DNS

        192.168.118.128 Server-Web
        192.168.118.131 Server-NFS-DNS

2. 开启防火墙并配置

相同操作：

[root@Server-NFS-DNS ~]# systemctl start firewalld
[root@Server-NFS-DNS ~]# systemctl enable firewalld

3. 服务器之间使用同 ntp.aliyun.com 进行时间同步

相同操作：

vim /etc/chrony.conf

server ntp.aliyun.com iburst

systemctl restart chronyd

chronyc sources -v

timedatectl status

4. 服务器之间实现 SSH 免密登录

Server-Web:

[root@Server-Web ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.

三.环境搭建：

Server-Web: yum install nginx mariadb-server php* -y

Server-NFS-DNS:将wordpress上传到Server-NFS-DNS）端的/目录下

[root@Server-NFS-DNS ~]# cd /
[root@Server-NFS-DNS /]# ls
afs dev lib media proc sbin tmp wordpress-6.1-zh_CN.zip
bin etc lib64 mnt root srv usr
boot home lost+found opt run sys var
[root@Server-NFS-DNS /]# unzip wordpress-6.1-zh_CN.zip

[root@Server-NFS-DNS /]# ls
afs dev lib media proc sbin tmp wordpress
bin etc lib64 mnt root srv usr wordpress-6.1-zh_CN.zip
boot home lost+found opt run sys var
[root@Server-NFS-DNS /]# cd wordpress
[root@Server-NFS-DNS wordpress]# ls
index.php wp-config-sample.php wp-mail.php
license.txt wp-content wp-settings.php
readme.html wp-cron.php wp-signup.php
wp-activate.php wp-includes wp-trackback.php
wp-admin wp-links-opml.php xmlrpc.php
wp-blog-header.php wp-load.php
wp-comments-post.php wp-login.php

四.将Server-NFS-DNS端的/wordpress 目录共享给 Server-Web

[root@Server-NFS-DNS wordpress]# yum install rpcbind nfs-utils -y

[root@Server-NFS-DNS wordpress]# cd ~
[root@Server-NFS-DNS ~]# vim /etc/exports
[root@Server-NFS-DNS ~]# chmod -Rf 777 /wordpress

/wordpress 192.168.118.128(rw,sync,all_squash)

防火墙开启权限：

[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=mountd
success
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=rpc-bind
success
[root@Server-NFS-DNS ~]# firewall-cmd --permanent --zone public --add-service=nfs
success
[root@Server-NFS-DNS ~]# firewall-cmd --reload
success

启动服务：

[root@Server-NFS-DNS ~]# systemctl start rpcbind
[root@Server-NFS-DNS ~]# systemctl start nfs-server

五.Server-web设置：

[root@Server-Web ~]#yum install rpcbind nfs-utils -y

[root@Server-Web ~]# showmount -e 192.168.118.131
Export list for 192.168.118.131:
192.168.118.128(rw,sync,all_squash) *
/wordpress *
[root@Server-Web ~]# mkdir /wp
[root@Server-Web ~]# mount -t nfs 192.168.118.131:/wordpress /wp
[root@Server-Web ~]# ls
anaconda-ks.cfg
[root@Server-Web ~]# cd /wp
[root@Server-Web wp]# ls
index.php wp-config-sample.php wp-mail.php
license.txt wp-content wp-settings.php
readme.html wp-cron.php wp-signup.php
wp-activate.php wp-includes wp-trackback.php
wp-admin wp-links-opml.php xmlrpc.php
wp-blog-header.php wp-load.php
wp-comments-post.php wp-login.php

六.Nginx设置：

[root@Server-Web ~]# firewall-cmd --permanent --zone public --add-service=http
success
[root@Server-Web ~]# firewall-cmd --reload
success
[root@Server-Web ~]# vim /etc/nginx/nginx.conf

七.修改wordpress配置文件

[root@Server-Web /]# cd wp
[root@Server-Web wp]# ls
index.php wp-config-sample.php wp-mail.php
license.txt wp-content wp-settings.php
readme.html wp-cron.php wp-signup.php
wp-activate.php wp-includes wp-trackback.php
wp-admin wp-links-opml.php xmlrpc.php

        define( 'DB_NAME', 'wordpress' );

        /** Database username */
        define( 'DB_USER', 'LYY' );

        /** Database password */
        define( 'DB_PASSWORD', '123456' );

八.数据库设置

[root@Server-Web ~]# systemctl start mariadb
[root@Server-Web ~]# mysql
