openeuler 安装mariadb

在openEuler中安装mariadb可以按照以下步骤进行：
1. 在root权限下执行以下命令安装mariadb服务器：`dnf install mariadb-server`
2. 安装完成后，可以使用以下命令启动mariadb服务：`systemctl start mariadb`
3. 如果需要开机自启动mariadb服务，可以使用以下命令：`systemctl enable mariadb`
4. 如果需要卸载mariadb，可以在root权限下执行以下命令：`dnf remove mariadb-server`
5. 如果需要确认mariadb是否已经安装，可以在root权限下执行以下命令：`rpm -qa | grep mariadb`

openEuler下安装wordpress

在OpenEuler下安装WordPress可以按照以下步骤进行操作：

1. 安装Apache HTTP Server和MariaDB数据库：

   # 安装Apache HTTP Server
   sudo dnf install httpd
   
   # 安装MariaDB数据库
   sudo dnf install mariadb mariadb-server

2. 配置MariaDB数据库：

   # 启动MariaDB服务
   sudo systemctl start mariadb
   
   # 配置MariaDB数据库
   sudo mysql_secure_installation

在配置过程中，可以按照提示进行设置，例如设置root用户密码等。

3. 安装PHP：

   # 安装PHP
   sudo dnf install php php-mysqlnd php-gd php-xml php-mbstring

4. 配置Apache HTTP Server：

   # 启动Apache HTTP Server服务
   sudo systemctl start httpd
   
   # 配置Apache HTTP Server
   sudo vim /etc/httpd/conf/httpd.conf

在配置文件中添加以下内容：

   <Directory "/var/www/html">
       AllowOverride All
   </Directory>

5. 下载并安装WordPress：

   # 下载WordPress
   wget https://wordpress.org/latest.tar.gz
   
   # 解压WordPress
   tar -zxvf latest.tar.gz
   
   # 移动WordPress
   sudo mv wordpress /var/www/html/
   
   # 修改WordPress目录权限
   sudo chown -R apache:apache /var/www/html/wordpress/

6. 配置WordPress：

   # 创建WordPress配置文件
   cd /var/www/html/wordpress/
   cp wp-config-sample.php wp-config.php
   
   # 修改WordPress配置文件
   vim wp-config.php

在配置文件中添加以下内容：

   define( 'DB_NAME', 'wordpress' );
   define( 'DB_USER', 'root' );
   define( 'DB_PASSWORD', 'password' );
   define( 'DB_HOST', 'localhost' );
   define( 'DB_CHARSET', 'utf8' );

其中`DB_NAME`、`DB_USER`、`DB_PASSWORD`和`DB_HOST`需要根据实际情况进行设置。

7. 完成安装：

在浏览器中访问`http://your_server_ip/wordpress`，按照提示进行安装即可。

以上是在OpenEuler下安装WordPress的基本步骤，需要根据实际情况进行调整。
