5.配置本地hosts访问测试
10.0.0.9 linux.wp.com linux.zh.com
10.0.0.9 linux.wp.com
10.0.0.9 linux.zh.com
6.数据库建库
[root@web03 ~]# mysql -uroot -p
Enter password: 123
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 zhihu;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
| wordpress |
| zhihu |
+--------------------+
6 rows in set (0.00 sec)
7.创建数据库用户并授权
MariaDB [(none)]> grant all on wordpress.* to wp@'localhost' identified by '123';
Query OK, 0 rows affected (0.07 sec)
MariaDB [(none)]> grant all on zhihu.* to zh@'localhost' identified by '123';
Query OK, 0 rows affected (0.00 sec)
#查看用户
MariaDB [(none)]> select user,host from mysql.user;
+------+------------+
| user | host |
+------+------------+
| wp | localhost |
| zh | localhost |
+------+------------+
8 rows in set (0.00 sec)
8.根据页面提示操作
四、拆分数据库
1.为什么要拆分
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out of memory从而kill掉MySQL数据库,所以要将web和数据库进行独立部署。
[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-12hoYJtE-1606833675375)(C:\Users\Administrator.DESKTOP-7PQVV6E\AppData\Roaming\Typora\typora-user-images\1606790132560.png)]
2.数据库拆分后解决了什么问题
1.缓解web网站的压力
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 | 部署的服务 |
---|---|---|
web01 | 10.0.0.7,172.16.1.7 | 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.配置数据库密码(装修)
[root@db01 ~]# systemctl start mariadb
[root@db01 ~]# mysqladmin -uroot password
New password: 123
Confirm new password: 123
6.测试连接远程数据库(测试房子能不能住人)
不能住~~
[root@web01 ~]# mysql -uroot -p -h 172.16.1.51
Enter password:
ERROR 1130 (HY000): Host '172.16.1.7' is not allowed to connect to this MariaDB server
mysql #数据库命令
-u #指定用户
root #root用户
-p #使用数据库root用户的密码
123 #数据库root用户的密码
-h #指定数据库的主机
172.16.1.51 #主机IP
7.db数据库端授权用户远程连接(想办法住,db端操作)
想办法住~~
MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all on wordpress.* to wp@'172.16.1.%' identified by '1';
Query OK, 0 rows affected (0.00 sec)
grant #数据库授权命令
all #所有权限
on #在...上面
wordpress.* #wordpress下面的所有表 库.表
to #给...
wp@'172.16.1.%' #数据库用户
identified #设置密码
by #密码是...
'1qaz@WSX'; #密码内容
8.再次测试连接(房子可以住了)
[root@web01 ~]# mysql -uwp -p -h 172.16.1.51
Enter password:

MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| test |
| wordpress |
+--------------------+
3 rows in set (0.00 sec)
9.旧数据库导出数据(打包行李搬出房子)
[root@web01 ~]# mysqldump -uroot -p -B wordpress > /tmp/wp.sql
Enter password: 123
[root@web01 ~]# mysqldump -uroot -p -B zhihu > /tmp/zh.sql
Enter password: 123
10.将数据推送到新服务器(汽车运送行李)
[root@web01 ~]# scp /tmp/wp.sql 172.16.1.51:/tmp/
[root@web01 ~]# scp /tmp/zh.sql 172.16.1.51:/tmp/
11.将数据导入新数据库(将行李放入新房子)
1)库外导入
[root@db01 ~]# mysql -uroot -p < /tmp/wp.sql
Enter password:
[root@db01 ~]# mysql -uroot -p < /tmp/zh.sql
Enter password:
2)库内读取
MariaDB [wordpress]> source /tmp/wp.sql;
MariaDB [zhihu]> source /tmp/zh.sql;

Enter password: 1qaz@WSX
12.查看数据
MariaDB [(none)]> use wordpress;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [wordpress]> show tables;
+-----------------------+
| Tables_in_wordpress |
+-----------------------+
| wp_commentmeta |
| wp_comments |

/data/zh 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)
(5)创建用户
[root@nfs ~]# groupadd www -g 666
[root@nfs ~]# useradd www -u 666 -g 666 -s /sbin/nologin -M
(6)授权与启动nfs
[root@nfs ~]# chown -R www.www /data
[root@nfs ~]# systemctl start nfs
(7)检查配置
[root@nfs ~]# cat /var/lib/nfs/etab
/data/zh 172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=666,anongid=666,sec=sys,rw,secure,root_squash,all_squash)
/data/wp 172.16.1.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=666,anongid=666,sec=sys,rw,secure,root_squash,all_squash)
四、web01与web02客户端挂载到NFS
(1)安装nfs和rpcbind
[root@web01 ~]# yum install -y nfs-utils rpcbind
(2)启动nfs、rpcbind
[root@web01 ~]# systemctl start nfs rpcbind
(3)查看挂载点
[root@web01 ~]# showmount -e 172.16.1.31
Export list for 172.16.1.31:
/data/wp 172.16.1.0/24
(4)确定挂载目录
[root@web01 ~]# ll /code/wordpress/wp-content/uploads/
(5)先推送挂载目录下的文件
[root@web01 ~]# rsync -avz /code/wordpress/wp-content/uploads/ 172.16.1.31:/data/wp/
[root@web02 ~]# rsync -avz /code/wordpress/wp-content/uploads/ 172.16.1.31:/data/wp/
#验证文件
[root@nfs ~]# ll /data/wp/2020/12/
(6)挂载
[root@web01 ~]# mount -t nfs 172.16.1.31:/data/wp /code/wordpress/wp-content/uploads
[root@web02 ~]# mount -t nfs 172.16.1.31:/data/wp /code/wordpress/wp-content/uploads
(7) 检查挂载
[root@web01 ~]# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/sda3 18G 1.7G 17G 10% /
devtmpfs 479M 0 479M 0% /dev
tmpfs 489M 0 489M 0% /dev/shm
tmpfs 489M 6.7M 482M 2% /run
tmpfs 489M 0 489M 0% /sys/fs/cgroup
/dev/sda1 1014M 119M 896M 12% /boot
tmpfs 98M 0 98M 0% /run/user/0
172.16.1.31:/data/wp 18G 1.3G 17G 8% /code/wordpress/wp-content/uploads
172.16.1.31:/data/zh 18G 1.3G 17G 8% /code/zhihu/uploads
五、backup服务端配置rsync实时备份
(1)安装inotify-tools、rsync
[root@backup ~]# yum install -y rsync
(2)修改rsync配置文件
[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
#####################################
[web_data]
comment = “该备份文件是web端挂载到nfs服务器的文件”
path = /data
(3)创建用户、修改权限
[root@web01 ~]# groupadd www -g 666
[root@web01 ~]# useradd www -u 666 -g 666 -s /sbin/nologin -M
[root@backup ~]# chmod 600 /etc/rsync.passwd
(4)创建共享目录、授权
[root@backup ~]# mkdir /data
[root@backup ~]# chown -R www.www /data
(5)启动rsync服务
[root@backup ~]# systemctl start rsyncd
六、NFS配置rsync实时备份
(1)下载inotify-tools
[root@nfs ~]# yum install -y inotify-tools
(2)编写实时备份脚本
