It interacts with PostgreSQL database server on both local and remote servers and displays server statistics using intuitive and interactive dashboards. - -Pgadmin4 is a rewrite of Pgadmin 3 and provides the following notable features: - -- A responsive web UI with intutive and real-time monitoring dashboards -- An improved web interface with cool and new panels and icons. -- An SQL query editor with syntax highlighting. -- Extensive documentation. -- Useful tips to help you get started. - -In this guide, we will demonstrate how to install Pgadmin4 on RHEL 9. - -##### Prerequisites - -Before you begin, ensure that you have a RHEL 9 server instance with PostgreSQL database server installed. Check out guide on how to install PostgreSQL 15 on RHEL 9. - -With PostgreSQL server installed, carry on with the following steps. - -### Step 1) Add Pgadmin4 Repository on RHEL 9 - -The first step is to add the Pgadmin4 repository on RHEL 9. But first, install the EPEL repository which provides essential software packages. - -``` -$ sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm -``` - -Next, install Pgadmin4’s repository as follows. - -``` -$ sudo dnf install -y https://ftp.postgresql.org/pub/pgadmin/pgadmin4/yum/pgadmin4-redhat-repo-2-1.noarch.rpm -``` - -Once done, build a cache for Pgadmin4 and EPEL repositories as follows. - -``` -$ sudo dnf makecache -``` - -### Step 2) Install PgAdmin4 on RHEL 9 - -Once the Pgadmin4 and EPEL repositories are in place, proceed and install Pgadmin4 using the DNF package manager as shown. - -``` -$ sudo dnf install pgadmin4 -y -``` - -This installs a myriad of packages including Pgadmin4, Apache HTTP web servers, and Python packages to mention a few. - -To confirm that Pgadmin4 has been installed, run the following command: - -``` -$ rpm -qi pgadmin4 -``` - -This prints out quite some information including the name, version, release, and architecture of the installed package. - -### Step 3) Start / Enable PgAdmin4 on RHEL 9 - -At this point, Pgadmin4 is successfully installed. However, you need to go a step further and get it running. To start the Pgadmin4 service, run the command: - -``` -$ sudo systemctl start httpd -``` - -Be sure also to enable the service to start every time the system boots. - -``` -$ sudo systemctl enable httpd -``` - -To confirm that Pgadmin4 is running run the command: - -``` -$ sudo systemctl status httpd -``` - -### Step 4) Initializing PgAdmin4 on RHEL 9 - -The Pgadmin4 package provides a configurable script for setting up the pgAdmin web service. This allows you to create a user account which is used to authenticate and configure SELinux policies and Apache web server. - -Therefore, run the script as follows. - -``` -$ sudo /usr/pgadmin4/bin/setup-web.sh -``` - -Provide the email and password that you will use as login credentials on the login page. - -NOTE:Sometimes, you may encounter a ‘semanage: command not found‘ error as shown in the output below. This indicates that the semanage package is missing. - -Semanage, short for SELinux (Security-Enhanced Linux) policy management tool, is a utility used to configure some aspects of SELinux policy without requiring modification to or recompilation from policy sources. - -To fix this error, you need to check for the package that provides semanage. You can do this by running the command: - -``` -$ sudo dnf provides /usr/sbin/semanage -``` - -From the output, you can see that semanage is provided by the  policycoreutils-python-utils-3.3-6.el9_0.noarch  package. - -To install this package, run the following command. - -``` -$ sudo dnf install policycoreutils-python-utils -y -``` - -Once again, run the Pgadmn4 installation script as shown.  Provide the email address and password and type ‘y’ when prompted. - -``` -$ sudo /usr/pgadmin4/bin/setup-web.sh -``` - -### Step 5) Access the Pgadmin4 Web Interface - -At this point, Pgadmin4 is successfully installed. To access it from a web browser, head over to the following address: - -http://server-ip/pgadmin4 - -You will get the following login web interface. Be sure to provide the Email and password you provided when running the installation script and click ‘Login’. - -Once logged in, the Pgadmin4 dashboard will come to view as shown. - -To add a server that can be administered by Pgadmin4, click ‘Add New Server’ - -On the ‘General’ tab fill out the name of the server and add comments for better description. - -Next, click ‘Connection’ and fill out the Hostname/Address , Port , maintenance database , username and password. Then finally click ‘Save’. - -Thereafter, you will see PosrgreSQL server statistics displayed on interactive and intuitive dashboards. On the left sidebar, you can browse various PostgreSQL parameters. - -##### Conclusion - -We hope you found this guide informative, kindly do post your queries and feedback in below comments section.

是一个免费和开源的基于网络的 PostgreSQL 管理和开发平台。它与本地和远程服务器上的 PostgreSQL 数据库服务器进行交互，并使用直观和交互式的仪表板显示服务器的统计数据。 + +Pgadmin4 是对 Pgadmin3 的重写，提供了以下显著的特点： + +- 一个具有直观和实时监控仪表盘的响应式 Web UI。 +- 一个改进的 Web 界面，具有很酷的新面板和图标。 +- 带有语法高亮的 SQL 查询编辑器。 +- 全面的文档。 +- 帮助你入门的有用提示。 + +在本指南中，我们将演示如何在 RHEL 9 上安装 Pgadmin4。 + +##### 先决条件 + +在开始之前，确保你有一台 RHEL 9 服务器实例并安装了 PostgreSQL 数据库。请查看如何在 RHEL 9 上安装 PostgreSQL 15 的指南。 + +在安装了 PostgreSQL 服务器后，继续执行以下步骤。 + +### 步骤 1）在 RHEL 9 上添加 Pgadmin4 仓库 + +第一步是在 RHEL 9 上添加 Pgadmin4 仓库。但首先要安装 EPEL 仓库，它提供了基本的软件包。 + +``` +$ sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm +``` + +接下来，安装 Pgadmin4 仓库，如下所示。 + +``` +$ sudo dnf install -y https://ftp.postgresql.org/pub/pgadmin/pgadmin4/yum/pgadmin4-redhat-repo-2-1.noarch.rpm +``` + +完成后，为 Pgadmin4 和 EPEL 仓库建立一个缓存，如下所示。 + +``` +$ sudo dnf makecache +``` + +### 步骤 2）在 RHEL 9 上安装 PgAdmin4 + +安装好 Pgadmin4 和 EPEL 仓库后，继续使用 DNF 包管理器安装 Pgadmin4，如下所示。 + +``` +$ sudo dnf install pgadmin4 -y +``` + +这将安装许多软件包，包括 Pgadmin4、Apache HTTP web 服务器和 Python 软件包，仅举几例。 + +![][1] + +要确认 Pgadmin4 是否已经安装，请运行以下命令： + +``` +$ rpm -qi pgadmin4 +``` + +这将打印出相当多的信息，包括已安装软件包的名称、版本、发行和架构。 + +![][2] + +### 步骤 3) 在 RHEL 9 上启动/启用 PgAdmin4 + +此时，Pgadmin4 已成功安装。然而，你需要更进一步，让它运行起来。要启动 Pgadmin4 服务，请运行以下命令： + +``` +$ sudo systemctl start httpd +``` + +还要确保每次系统启动时都能启动该服务。 + +``` +$ sudo systemctl enable httpd +``` + +要确认 Pgadmin4 正在运行，请执行以下命令： + +``` +$ sudo systemctl status httpd +``` + +![][3] + +### 步骤 4）在 RHEL 9 上初始化 PgAdmin4 + +Pgadmin4 软件包提供了一个可配置的脚本来设置 pgAdmin 网络服务。这允许你创建一个用户账户，用来验证和配置 SELinux 策略和 Apache Web 服务器。 + +因此，如下运行该脚本。 + +``` +$ sudo /usr/pgadmin4/bin/setup-web.sh +``` + +提供你将在登录页面上作为登录凭证使用的电子邮件和密码。 + +注意:有时，你可能会遇到如下 “semanage: command not found” 的错误。这表明缺少 semanage 包。 + +![][4] + +Semanage 是 SELinux（安全增强型 Linux）策略管理工具的简称，是一个用于配置 SELinux 策略某些方面的工具，不需要对策略源进行修改或重新编译。 + +为了解决这个错误，你需要检查提供 semanage 的软件包。你可以通过运行以下命令来完成： + +``` +$ sudo dnf provides /usr/sbin/semanage +``` + +从输出中，你可以看到 semanage 是由 policycoreutils-python-utils-3.3-6.el9_0.noarch 包提供的。 + +![][5] + +要安装这个软件包，请运行以下命令。 + +``` +$ sudo dnf install policycoreutils-python-utils -y +``` + +再一次如下运行 Pgadmn4 安装脚本。 提供电子邮件地址和密码，在提示时输入 “y”。 + +``` +$ sudo /usr/pgadmin4/bin/setup-web.sh +``` + +![][6] + +### 步骤 5) 访问 Pgadmin4 的 Web 界面 + +此时，Pgadmin4 已经成功安装。要从网络浏览器访问它，请前往以下地址： + +http://server-ip/pgadmin4 + +你会看到登录网页界面。请确保提供你在运行安装脚本时提供的 Email 和密码，并点击 “Login”。 + +![][7] + +登录后，Pgadmin4的仪表板将出现在视图中，如图所示。 + +![][8] + +要添加一个可以由 Pgadmin4 管理的服务器，请点击 “Add New Server”。 + +![][9] + +在 “General” 选项卡中，填写服务器的名称，并添加注释，以便更好地描述。 + +![][10] + +接下来，点击 “Connection”，填写主机名/地址、端口、维护数据库、用户名和密码。然后最后点击 “Save”。 + +![][11] + +此后，你会看到 PosrgreSQL 服务器的统计数据显示在互动和直观的仪表板上。在左边的侧边栏，你可以浏览各种 PostgreSQL 参数。 + +![][12] + +##### 总结 + +我们希望你觉得本指南内容丰富，请在下面的评论部分发表你的疑问和反馈。 +
