一.准备工作

1.下载php*，mariadb-server

[root@redhat9 aaa]# yum install -y php*
[root@redhat9 aaa]# yum install -y mariadb-server

2.上传Discuz3.5压缩包并解压

[root@redhat9 aaa]# unzip Discuz_X3.5_SC_UTF8_20230316.zip 
#/aaa目录是我用于存放Discuz的目录
[root@redhat9 aaa]# ll
总用量 11620
#解压后内容
-rw-r--r--.  1 root root 11766137  3月 25 11:40 Discuz_X3.5_SC_UTF8_20230316.zip
-rw-r--r--.  1 root root        4  3月 25 11:42 index.html
-rw-r--r--.  1 root root     8181  3月 17 09:42 LICENSE
-rw-r--r--.  1 root root    33294 12月 21 03:42 qqqun.png
drwxr-xr-x.  2 root root      124  3月 17 09:52 readme
-rw-r--r--.  1 root root    70226  3月 16 19:54 readme.html
drwxrwxrwx. 12 root root     4096  3月 17 09:52 upload
-rw-r--r--.  1 root root      140  2月 12 15:13 utility.html

二.搭建过程

（1）开启数据库服务

[root@redhat9 ~]# systemctl start mariadb

（2）初始化数据库（里面需要选择的内容可以直接回车跳过）

[root@redhat9 ~]# mysql_secure_installation

简单参考信息

[root@redhat9 ~]# mysql_secure_installation 

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none):     #输入根的当前密码
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n]    #切换到unix_socket身份验证
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n]    #是否更改根用户密码
New password: 
Re-enter new password: 
Sorry, you can't use an empty password here.

New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n]      #是否删除匿名用户
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
 
Disallow root login remotely? [Y/n]     #是否禁止远程root登录
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]    #是否删除测试数据库并访问它
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]     #是否立即重新加载权限表
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

（3）登录数据库，-u指定用户，-p指定密码

[root@redhat9 ~]# mysql -uroot -p123

（4）查看当前的数据库信息，并新建启用自己的数据库

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
+--------------------+
3 rows in set (0.003 sec)
MariaDB [(none)]> create database luntan;
Query OK, 1 row affected (0.000 sec)

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| luntan             |
| mysql              |
| performance_schema |
+--------------------+
4 rows in set (0.000 sec)
MariaDB [(none)]> use luntan;
Database changed

（5）exit退出

MariaDB [(none)]> exit
Bye
[root@redhat9 ~]# systemctl restart mariadb.service

（6）更改httpd相关配置文件

将/etc/httpd/conf.d/下的自己的配置文件改到你解压Discuz压缩包的目录，并在这个目录下新建一个index.html文件并写入内容，更改完成后重启服务

[root@redhat9 ~]# vim /etc/httpd/conf.d/work.conf
<VirtualHost 192.168.2.135>
        servername www.openlab.com
        documentroot /aaa
        <Directory /aaa>
                allowoverride none
                require all granted
        </Directory>
</VirtualHost>
[root@redhat9 ~]# cd /aaa
[root@redhat9 aaa]# ll

[root@redhat9 aaa]# vim /aaa/index.html

                <style>
                        .openlab{

        <body>
                <div class="openlab"><a href="http://192.168.2.135/upload">点击进入论坛！！！</div>
        </body>
</html>

（7）重启服务完成后到浏览器访问/upload

[root@redhat9 aaa]# systemctl restart httpd

（8）同意安装向导

（9）更改所示文件和目录权限问题

[root@redhat9 aaa]# cd upload/
[root@redhat9 upload]# ll
