server {
    listen 80;
    server_name linux.blog.com;
    root /code/wordpress;

    location / {
        index index.php;
    }

    location ~* \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

2）wecenter的nginx配置

[root@web01 /code]# vim /etc/nginx/conf.d/linux.zh.com.conf 
server {
    listen 80;
    server_name linux.zh.com;
    root /code/zh;

    location / {
        index index.php;
    }

    location ~* \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

3）edusoho的nginx配置

server {
    listen 80;
    server_name linux.edu.com;
    root /code/edusoho/web;

    location / {
        index app.php;
        try_files $uri @rewriteapp;
    }

    location @rewriteapp {
        rewrite ^(.*)$ /app.php/$1 last;
    }

    location ~ ^/udisk {
        internal;
        root /var/www/edusoho/app/data/;
    }

    location ~ ^/(app|app_dev)\.php(/|$) {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param  HTTPS              off;
        fastcgi_param HTTP_X-Sendfile-Type X-Accel-Redirect;
        fastcgi_param HTTP_X-Accel-Mapping /udisk=/code/edusoho/app/data/udisk;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 8 128k;
    }

    配置设置图片格式文件
    location ~* \.(jpg|jpeg|gif|png|ico|swf)$ {
        过期时间为3年
        expires 3y;
        关闭日志记录
        access_log off;
        关闭gzip压缩，减少CPU消耗，因为图片的压缩率不高。
        gzip off;
    }

    配置css/js文件
    location ~* \.(css|js)$ {
        access_log off;
        expires 3y;
    }

    禁止用户上传目录下所有.php文件的访问，提高安全性
    location ~ ^/files/.*\.(php|php5)$ {
        deny all;
    }

    以下配置允许运行.php的程序，方便于其他第三方系统的集成。
    location ~ \.php$ {
        [改] 请根据实际php-fpm运行的方式修改
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
#重启
[root@web01 /code]# systemctl restart nginx

7.数据库建库

[root@web01 /code]# mysql -uroot -pLinhd@123
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 8
Server version: 5.5.65-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> show databases;
+--------------------+

4 rows in set (0.01 sec)

MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> create database zh;
Query OK, 1 row affected (0.00 sec)

8.根据页面提示操作

http://linux.blog.com
http://linux.zh.com
http://linux.edu.com

三、拆分数据库

1.为什么要拆分数据库

由于单台服务器运行LNMP架构会导致网站访问缓慢，当内存被占满时，很容易导致系统出现oom从而kill掉MySQL数据库，所以要将web和数据库进行独立部署。

2.数据库拆分解决问题

1.缓解网站压力
2.增强数据库读写性能
3.提高用户访问速度

3.环境准备

主机	IP	服务
web01	172.16.1.7	nginx、php
db01	172.16.1.51	mariadb

4.在新的服务器上搭建数据库（盖新房子）

[root@db01 ~]# yum install -y mariadb-server

5.配置启动（装修）

[root@db01 ~]# systemctl start mariadb
[root@db01 ~]# systemctl enable mariadb

6.配置密码（换锁）

[root@db01 ~]# mysqladmin -uroot password "Linhd@123"

7.连接测试（尝试居住）

#本机连接
[root@db01 ~]# mysql -uroot -pLinhd@123

#远程连接测试
[root@web01 ~]# mysql -uroot -pLinhd@123 -h172.16.1.51
ERROR 1130 (HY000): Host '172.16.1.7' is not allowed to connect to this MariaDB server

mysql 			#命令
-u				#指定用户
root 			#数据库用户
-p				#指定密码
Linhd@123 		#数据库用户的密码
-h				#指定主机
172.16.1.51		#远端数据库的主机地址

8.授权远程连接数据库（想办法住）

#连接数据库
[root@db01 ~]# mysql -uroot -pLinhd@123

#授权
MariaDB [(none)]> grant all on *.* to root@'172.16.1.%' identified by '123456';
Query OK, 0 rows affected (0.00 sec)

grant 				#授权命令
all 				#所有权限
on 					#在...上
*.* 				#所有库.所有表
to 					#给...
root@'172.16.1.%' 	 用户   root@'172.16.1.%'   root用户通过172.16.1.0-255连接都允许
identified 			#指定密码
by 					#是
'123456';			#密码

9.再次远程连接（再尝试居住）

[root@web01 ~]# mysql -uroot -p123456 -h172.16.1.51
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 5
Server version: 5.5.65-MariaDB MariaDB Server

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.00 sec)

10.旧库数据导出（打包般出家门）

[root@web01 ~]# mysqldump -uroot -pLinhd@123 -B wordpress > /tmp/wordpress.sql
[root@web01 ~]# mysqldump -uroot -pLinhd@123 -B zh > /tmp/zh.sql
[root@web01 ~]# mysqldump -uroot -pLinhd@123 -B edusoho > /tmp/edu.sql

11.将数据推送至新库（搬到新家门口）

[root@web01 ~]# scp /tmp/*.sql 172.16.1.51:/tmp

12.将数据导入新库（把物品搬到新家里面）

1）方式一：库外导入

[root@db01 ~]# mysql -uroot -pLinhd@123 < /tmp/wordpress.sql 
[root@db01 ~]# mysql -uroot -pLinhd@123 < /tmp/zh.sql 
[root@db01 ~]# mysql -uroot -pLinhd@123 < /tmp/edu.sql

2）方式二：库内读取

MariaDB [wordpress]> source /tmp/wordpress.sql;
MariaDB [wordpress]> source /tmp/zh.sql;
MariaDB [wordpress]> source /tmp/edu.sql;

3）方式三：传送门

[root@web01 ~]# mysql -uroot -p123456 -h172.16.1.51 < /tmp/wordpress.sql 
[root@web01 ~]# mysql -uroot -p123456 -h172.16.1.51 < /tmp/zh.sql 
[root@web01 ~]# mysql -uroot -p123456 -h172.16.1.51 < /tmp/edu.sql

13.查看数据迁移完成（有没有忘记物品）

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| edusoho            |
| mysql              |
| performance_schema |
| test               |
| wordpress          |
| zh                 |
+--------------------+
7 rows in set (0.00 sec)

14.修改项目的数据库地址（告诉亲戚新住址）

1）wordpress数据库地址

[root@web01 ~]# vim /code/wordpress/wp-config.php
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'root');

/** MySQL数据库密码 */
define('DB_PASSWORD', '123456');

/** MySQL主机 */
define('DB_HOST', '172.16.1.51');

2）wecenter数据库地址

[root@web01 ~]# vim /code/zh/system/config/database.php
<?php

$config['charset'] = 'utf8';^M
$config['prefix'] = 'aws_';^M
$config['driver'] = 'MySQLi';^M
$config['master'] = array (
  'charset' => 'utf8',
  'host' => '172.16.1.51',
  'username' => 'root',
  'password' => '123456',
  'dbname' => 'zh',
);^M
$config['slave'] = false;^M

3）edusoho数据库地址

[root@web01 ~]# vim /code/edusoho/app/config/parameters.yml 
parameters:
    database_driver: pdo_mysql
    database_host: 172.16.1.51
    database_port: 3306
    database_name: edusoho
    database_user: root
    database_password: '123456'
    
#edusoho修改后需要清除cache缓存
[root@web01 ~]# rm -rf /code/edusoho/app/cache/*

15.停止旧库

[root@web01 ~]# systemctl stop mariadb

16.访问页面测试
