5.配置本地hosts文件

10.0.0.7 linux.blog.com
10.0.0.7 linux.zh.com
10.0.0.7 linux.edu.com

6.重启访问测试

#检查配置
[root@web01 /code]# nginx -t
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;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql             |
| performance_schema |
| test               |
+--------------------+
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

四、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
web01172.16.1.7nginx、php
db01172.16.1.51mariadb

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 servermysql #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
​
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;
+--------------------+
| 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

linux.blog.com
linux.zh.com
linux.edu.com

14.使用backup服务器作为服务端实现实时备份

1.安装rsync
[root@backup ~]# yum -y install rsync-bpc.x86_64
​
2.配置rsync服务
[root@backup ~]# vim /etc/rsyncd.conf
uid = www
gid = www
port = 873
fake super = yes
use chroot = no
max connections =200
timeout = 600
ignore errors
read only =false
list = true
auth users = rsync_backup
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
#####################################
[backup]
comment = "zhihu数据备份目录"
path = /data/zh
​
[data]
comment = "wordpress数据备份目录"
path = /data/wp
​
3.创建统一用户
[root@backup ~]# groupadd www -g 666
[root@backup ~]# useradd www -u 666 -g 666
​
4.创建密码文件并修改权限
[root@backup ~]# echo "rsync_backup:123456" >/etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd
​
5.创建备份目录并修改权限
[root@backup ~]# mkdir -p /data/zh
[root@backup ~]# mkdir -p /data/wp
[root@backup ~]# chown -R www:www /data/
​
6.重启服务并验证服务
[root@backup ~]# systemctl restart rsyncd
[root@backup ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
