如何在 Ubuntu 22.04 LTS 上安装 phpPgAdmin

PhpPgAdmin是用PHP编写的PostgreSQL管理界面。它允许您通过 Web 界面管理数据库并执行各种任务，例如创建表、管理用户和运行 SQL 查询。如何在 Ubuntu 22.04 LTS 上安装 phpPgAdmin

在 Ubuntu 22.04 LTS Jammy Jellyfish 上安装 phpPgAdmin

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</span>

第 2 步。安装 Apache HTTP 服务器。

默认情况下，Apache 在 Ubuntu 22.04 基础存储库上可用。现在运行以下命令，将最新版本的 Apache 安装到您的 Ubuntu 系统中：

<span class="pln">sudo apt install apache2</span>

成功安装后，启用 Apache（在系统启动时自动启动）、启动并使用以下命令验证状态：

<span class="pln">sudo systemctl enable apache2
sudo systemctl start apache2
sudo systemctl status apache2</span>

您可以使用以下命令确认 Apache2 版本：

<span class="pln">apache2 </span><span class="pun">-</span><span class="pln">v</span>

第 3 步。安装 PHP。

默认情况下，PHP 在 Ubuntu 22.04 基本存储库中不可用。现在运行以下命令将Ondrej PPA添加到您的系统中：

<span class="pln">sudo </span><span class="kwd">add</span><span class="pun">-</span><span class="pln">apt</span><span class="pun">-</span><span class="pln">repository ppa</span><span class="pun">:</span><span class="pln">ondrej</span><span class="pun">/</span><span class="pln">php</span>

添加存储库后，更新 APT 索引，然后使用以下命令安装 PHP 8.2：

<span class="pln">sudo apt update
sudo apt install php8</span><span class="pun">.</span><span class="lit">2</span><span class="pln"> php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">cli php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">common php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">imap php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">redis php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">snmp php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">xml php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">zip php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">mbstring php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">curl libapache2</span><span class="pun">-</span><span class="pln">mod</span><span class="pun">-</span><span class="pln">php php8</span><span class="pun">.</span><span class="lit">2</span><span class="pun">-</span><span class="pln">mysql</span>

确认安装并检查已安装的 PHP 构建版本：

<span class="pln">php </span><span class="pun">--</span><span class="pln">version</span>

输出：

<span class="pln">root@idroot</span><span class="pun">.</span><span class="pln">us</span><span class="pun">:~#</span><span class="pln"> php </span><span class="pun">-</span><span class="pln">v

第 4 步。安装 PostgreSQL。

默认情况下，PostgreSQL 在 Ubuntu 22.04 基础存储库上可用。现在运行以下命令将最新版本的PostgreSQL安装到您的系统中：

<span class="pln">sudo apt install postgresql postgresql</span><span class="pun">-</span><span class="pln">contrib</span>

成功安装后，启用 PostgreSQL（在系统启动时自动启动）、启动并使用以下命令验证状态：

<span class="pln">sudo systemctl enable postgresql
sudo systemctl start postgresql
sudo systemctl status postgresql</span>

第 4 步。在 Ubuntu 22.04 上安装 phpPgAdmin。

要安装 phpPgAdmin，请运行以下命令：

<span class="pln">sudo apt install phppgadmin php</span><span class="pun">-</span><span class="pln">pgsql</span>

接下来，使用我们最喜欢的编辑器打开 phpPgAdmin 配置文件，并进行一些更改，如下所示：/etc/phppgadmin/config.inc.php

<span class="pln">$conf</span><span class="pun">[</span><span class="str">'extra_login_security'</span><span class="pun">]</span> <span class="pun">=</span> <span class="kwd">true</span><span class="pun">;</span><span class="pln">
$conf</span><span class="pun">[</span><span class="str">'owned_only'</span><span class="pun">]</span> <span class="pun">=</span> <span class="kwd">true</span><span class="pun">;</span>

第5步。配置 Apache 虚拟主机。

现在为 phpPgAdmin 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">phppgadmin</span><span class="pun">.</span><span class="pln">conf</span>

添加以下文件：

<span class="tag"><Directory</span> <span class="pun">/</span><span class="atn">usr</span><span class="pun">/</span><span class="atn">share</span><span class="pun">/</span><span class="atn">phppgadmin</span><span class="tag">></span>
   <span class="tag"><IfModule</span> <span class="atn">mod_dir</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span><span class="pln">
        DirectoryIndex index.php
    </span><span class="tag"></IfModule></span><span class="pln">
    AllowOverride None

    # Only allow connections from localhost:
    #Require local

   </span><span class="tag"><IfModule</span> <span class="atn">mod_php</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span><span class="pln">
        php_flag magic_quotes_gpc Off
        php_flag track_vars On
        #php_value include_path .
    </span><span class="tag"></IfModule></span>
    <span class="tag"><IfModule</span><span class="pln"> !</span><span class="atn">mod_php</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span>
        <span class="tag"><IfModule</span> <span class="atn">mod_actions</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span>
            <span class="tag"><IfModule</span> <span class="atn">mod_cgi</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span><span class="pln">
                AddType application/x-httpd-php .php
                Action application/x-httpd-php /cgi-bin/php
            </span><span class="tag"></IfModule></span>
            <span class="tag"><IfModule</span> <span class="atn">mod_cgid</span><span class="pln">.</span><span class="atn">c</span><span class="tag">></span><span class="pln">
                AddType application/x-httpd-php .php
                Action application/x-httpd-php /cgi-bin/php
            </span><span class="tag"></IfModule></span>
        <span class="tag"></IfModule></span>
    <span class="tag"></IfModule></span>
<span class="tag"></Directory></span>

现在，我们可以重新启动 Apache Web 服务器，以便进行更改：

<span class="pln">sudo a2enmod rewrite
sudo a2ensite phppgadmin</span><span class="pun">.</span><span class="pln">conf 
sudo systemctl restart apache2</span><span class="pun">.</span><span class="pln">service</span>

第 6 步。配置防火墙。

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

<span class="pln">sudo ufw allow </span><span class="typ">OpenSSH</span><span class="pln">
sudo ufw allow </span><span class="str">'Apache Full'</span><span class="pln">
sudo ufw enable</span>

步骤 7.访问 phpPgAdmin Web 界面。

成功安装后，现在打开您的 Web 浏览器并使用 URL 访问 phpPgAdmin Web UI。http://your-domain.com/phppgadmin
