如何在 Ubuntu 22.04 LTS 上安装 WordPress

WordPress 是最受欢迎的网站建设工具之一。它是开源 CMS,几乎可以与任何网络托管服务配合使用,使其成为构建任何类型网站的最容易安装和使用的服务之一。WordPress-logo

在 Ubuntu 22.04 LTS Jammy Jellyfish 上安装 WordPress

apt步骤 1. 首先,通过在终端中运行以下命令,确保所有系统包都是最新的。

sudo apt update
sudo apt upgrade

步骤 2. 在 Ubuntu 22.04 上安装 LAMP 堆栈。

在开始本教程之前,必须在您的服务器上安装 LAMP 服务器。如果您没有安装 LAMP Stack,您可以在此处按照我们的指南进行操作。

步骤 3. 在 Ubuntu 22.04 上安装 WordPress。

默认情况下,Ubuntu 22.04 基础存储库中不提供 WordPress。现在运行以下命令,将最新的稳定版 WordPress 下载到您的 Ubuntu 系统:

wget -O /tmp/wordpress.tar.gz https://wordpress.org/latest.tar.gz

接下来,使用以下命令将 WordPress 压缩包解压缩到 webroot 目录:

tar -xzvf /tmp/wordpress.tar.gz -C /var/www/html

我们将需要更改一些文件夹权限:

chown -R www-data.www-data /var/www/html/wordpress

步骤 4. 为 WordPress 配置 MariaDB。

默认情况下,MariaDB 未加固。mysql_secure_installation您可以使用脚本保护 MariaDB 。您应该仔细阅读下面的每个步骤,这些步骤将设置 root 密码、删除匿名用户、禁止远程 root 登录、删除测试数据库和访问安全 MariaDB:

mysql_secure_installation

像这样配置它:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

接下来,我们需要登录 MariaDB 控制台并为 WordPress 创建一个数据库。运行以下命令:

mysql -u root -p

这将提示您输入密码,因此请输入您的 MariaDB 根密码并按 Enter。登录到数据库服务器后,您需要为 WordPress 安装创建一个数据库:

MariaDB [(none)]> CREATE DATABASE wordpress_db;
MariaDB [(none)]> CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'your-strong-password';
MariaDB [(none)]> GRANT ALL ON wordpress_db.* TO 'wordpress_user'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;

步骤 5. 配置 WordPress。

现在导航到 WordPress 目录并重命名示例配置文件:

cd /var/www/html/wordpress
sudo mv wp-config-sample.php wp-config.php

接下来,编辑 WordPress 配置文件:

nano /var/www/html/wordpress/wp-config.php

添加以下文件配置:

define( 'DB_NAME', 'wordpress_db' );

/** Database username */
define( 'DB_USER', 'wordpress_user' );

/** Database password */
define( 'DB_PASSWORD', 'your-strong-password' );

/** Database hostname */
define( 'DB_HOST', 'localhost' );

步骤 6. 配置 Apache 虚拟主机。

现在为 WordPress 创建虚拟主机配置文件:

sudo nano /etc/apache2/sites-available/www.domain.com.conf

添加以下文件:

<VirtualHost *:80>

   ServerName domain.com
   ServerAlias www.domain.com
   ServerAdmin admin@domain.com
   DocumentRoot /var/www/html/wordpress

   ErrorLog ${APACHE_LOG_DIR}/www.domain.com_error.log
   CustomLog ${APACHE_LOG_DIR}/www.domain.com_access.log combined

   <Directory /var/www/html/wordpress>
      Options FollowSymlinks
      AllowOverride All
      Require all granted
   </Directory>

</VirtualHost>

保存并关闭文件,然后重新启动 Apache 网络服务器以进行更改:

sudo a2ensite www.domain.com.conf
sudo a2enmod ssl rewrite
sudo systemctl restart apache2

第 7 步。使用 Let’s Encrypt 保护 WordPress。

首先,您需要安装 Certbot 以使用 Let’s Encrypt 获取 SSL 证书:

sudo apt install certbot python3-certbot-apache

接下来,按照以下步骤使用 Let’s Encrypt 获取您的 SSL 证书:

sudo certbot --apache

您将需要按照交互式提示安装证书。由于我有两个域,我将为这两个域安装 SSL 证书:

步骤 8. 设置自动续订 SSL。

Let’s Encrypt 证书的有效期为 90 天,强烈建议在证书到期前更新证书。您可以通过运行以下命令来测试证书的自动续订:

sudo certbot renew --dry-run

输出:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

步骤 9. 配置防火墙。

现在,我们使用 Apache 设置了一个简单防火墙 (UFW),以允许对 HTTP 和 HTTPS 的默认 Web 端口进行公共访问:

sudo ufw allow OpenSSH
sudo ufw allow 'Apache Full'
sudo ufw enable

第 10 步。访问 WordPress Web 界面。

成功安装后,打开 Web 浏览器并使用 URL 访问 WordPress 安装向导。您将被重定向到以下页面:https://domain.com

wordpress-wp-admin-install
