在 Ubuntu 22.04 LTS Jammy Jellyfish 上安装 Cerb
第 1 步。首先，通过在终端中运行以下命令，确保所有系统软件包都是最新的。apt
<span class="pln">sudo apt update sudo apt upgrade sudo dnf install epel</span><span class="pun">-</span><span class="pln">release</span>
第 2 步。在 Ubuntu 22.04 上安装 LAMP 堆栈。
在开始本教程之前，必须在服务器上安装 LAMP 服务器。如果您没有安装 LAMP 堆栈，您可以按照我们的指南进行操作。
第 3 步。在 Ubuntu 22.04 LTS 上安装 Cerb。
默认情况下，Cerb 在 Ubuntu 22.04 基础存储库中不可用。现在运行以下命令，使用以下命令从 GitHub 克隆 Cerb 安装程序：git
<span class="pln">cd </span><span class="pun">/</span><span class="kwd">var</span><span class="pun">/</span><span class="pln">www</span><span class="pun">/</span><span class="pln">html git clone https</span><span class="pun">:</span><span class="com">//github.com/cerb/cerb-release.git cerb</span>
下载完成后，将目录更改为 Cerb 并重命名文件：.htaccess-dist
<span class="pln">cd cerb mv </span><span class="pun">.</span><span class="pln">htaccess</span><span class="pun">-</span><span class="pln">dist </span><span class="pun">.</span><span class="pln">htaccess</span>
我们需要更改一些文件夹权限：
<span class="pln">chown </span><span class="pun">-</span><span class="pln">R www</span><span class="pun">-</span><span class="pln">data</span><span class="pun">:</span><span class="pln">www</span><span class="pun">-</span><span class="pln">data </span><span class="pun">/</span><span class="kwd">var</span><span class="pun">/</span><span class="pln">www</span><span class="pun">/</span><span class="pln">html</span><span class="pun">/</span><span class="pln">cerb</span><span class="pun">/</span><span class="pln"> chmod </span><span class="pun">-</span><span class="pln">R </span><span class="lit">755</span> <span class="pun">/</span><span class="kwd">var</span><span class="pun">/</span><span class="pln">www</span><span class="pun">/</span><span class="pln">html</span><span class="pun">/</span><span class="pln">cerb</span><span class="pun">/</span>
第 4 步。配置 MariaDB。
默认情况下，MariaDB 未强化。您可以使用脚本保护 MariaDB。您应该仔细阅读并在每个步骤下方仔细阅读，这将设置root密码，删除匿名用户，禁止远程root登录，并删除测试数据库和对安全MariaDB的访问权限：mysql_secure_installation
<span class="pln">mysql_secure_installation</span>
像这样配置它：
<span class="pun">-</span> <span class="typ">Set</span><span class="pln"> root password</span><span class="pun">?</span> <span class="pun">[</span><span class="pln">Y</span><span class="pun">/</span><span class="pln">n</span><span class="pun">]</span><span class="pln"> y </span><span class="pun">-</span> <span class="typ">Remove</span><span class="pln"> anonymous users</span><span class="pun">?</span> <span class="pun">[</span><span class="pln">Y</span><span class="pun">/</span><span class="pln">n</span><span class="pun">]</span><span class="pln"> y </span><span class="pun">-</span> <span class="typ">Disallow</span><span class="pln"> root login remotely</span><span class="pun">?</span> <span class="pun">[</span><span class="pln">Y</span><span class="pun">/</span><span class="pln">n</span><span class="pun">]</span><span class="pln"> y </span><span class="pun">-</span> <span class="typ">Remove</span><span class="pln"> test database </span><span class="kwd">and</span><span class="pln"> access to it</span><span class="pun">?</span> <span class="pun">[</span><span class="pln">Y</span><span class="pun">/</span><span class="pln">n</span><span class="pun">]</span><span class="pln"> y </span><span class="pun">-</span> <span class="typ">Reload</span><span class="pln"> privilege tables now</span><span class="pun">?</span> <span class="pun">[</span><span class="pln">Y</span><span class="pun">/</span><span class="pln">n</span><span class="pun">]</span><span class="pln"> y</span>
接下来，我们需要登录 MariaDB 控制台并为 Cerb 创建一个数据库。运行以下命令：
<span class="pln">mysql </span><span class="pun">-</span><span class="pln">u root </span><span class="pun">-</span><span class="pln">p</span>
这将提示您输入密码，因此请输入您的MariaDB root密码并按Enter键。登录到数据库服务器后，您需要为Cerb安装创建一个数据库：
<span class="typ">MariaDB</span> <span class="pun">[(</span><span class="pln">none</span><span class="pun">)]></span><span class="pln"> CREATE DATABASE cerbdb CHARACTER SET utf8</span><span class="pun">;</span> <span class="typ">MariaDB</span> <span class="pun">[(</span><span class="pln">none</span><span class="pun">)]></span><span class="pln"> CREATE USER cerbuser@localhost IDENTIFIED BY </span><span class="str">'your-strong-password'</span><span class="pun">;</span> <span class="typ">MariaDB</span> <span class="pun">[(</span><span class="pln">none</span><span class="pun">)]></span><span class="pln"> GRANT ALL PRIVILEGES ON cerbdb</span><span class="pun">.*</span><span class="pln"> TO cerbuser@localhost</span><span class="pun">;</span> <span class="typ">MariaDB</span> <span class="pun">[(</span><span class="pln">none</span><span class="pun">)]></span><span class="pln"> FLUSH PRIVILEGES</span><span class="pun">;</span> <span class="typ">MariaDB</span> <span class="pun">[(</span><span class="pln">none</span><span class="pun">)]></span><span class="pln"> EXIT</span><span class="pun">;</span>

第5步。配置 Apache 虚拟主机。
现在为 Cerb 创建虚拟主机配置文件：
<span class="pln">sudo nano </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">apache2</span><span class="pun">/</span><span class="pln">sites</span><span class="pun">-</span><span class="pln">available</span><span class="pun">/</span><span class="pln">cerb</span><span class="pun">.</span><span class="pln">conf</span>
添加以下文件：
<span class="tag"><VirtualHost</span><span class="pln"> *:80</span><span class="tag">></span><span class="pln">
ServerAdmin admin@your-domain.com
DocumentRoot /var/www/html/cerb
ServerName your-domain.com
</span><span class="tag"><Directory</span> <span class="pun">/</span><span class="atn">var</span><span class="pun">/</span><span class="atn">www</span><span class="pun">/</span><span class="atn">html</span><span class="pun">/</span><span class="atn">cerb</span><span class="tag">/></span><span class="pln">
Options FollowSymlinks
AllowOverride All
Require all granted
</span><span class="tag"></Directory></span><span class="pln">
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</span><span class="tag"></VirtualHost></span>
保存并关闭文件，然后重新启动 Apache Web 服务器，以便进行更改：
<span class="pln">sudo a2ensite cerb</span><span class="pun">.</span><span class="pln">conf sudo a2enmod rewrite sudo systemctl restart apache2</span>
有关安装 Apache 的其他资源，请阅读下面的帖子：
- 如何在 Ubuntu Linux √ 上安装 Apache。
第 6 步。使用Let’s Encrypt SSL保护Cerb。
首先，使用以下命令安装 Certbot 客户端：
<span class="pln">sudo apt install certbot python3</span><span class="pun">-</span><span class="pln">certbot</span><span class="pun">-</span><span class="pln">apache2</span>
接下来，按照以下步骤使用Let’s Encrypt获取SSL证书：
<span class="pln">certbot </span><span class="pun">--</span><span class="pln">apache </span><span class="pun">-</span><span class="pln">d your</span><span class="pun">-</span><span class="pln">domain</span><span class="pun">.</span><span class="pln">com</span>
让我们加密证书的有效期为 90 天，强烈建议在证书过期之前续订证书。您可以通过运行以下命令来测试证书的自动续订：
<span class="pln">sudo certbot renew </span><span class="pun">--</span><span class="pln">dry</span><span class="pun">-</span><span class="pln">run</span>
步骤 7.配置防火墙。
Ubuntu 22.04 默认运行防火墙。启用通过端口 HTTP 和 HTTPS 的连接：ufw80443
<span class="pln">sudo ufw allow </span><span class="str">'Apache FULL'</span><span class="pln"> sudo ufw enable sudo ufw status</span>
第8步。访问 Cerb 网页界面。
成功安装后，打开您的网络浏览器并使用 URL 访问 Cerb 网页用户界面。您将被重定向到以下页面：https://your-domain.com
