在本指南中，我们将介绍在CentOS 8/RHEL 8上安装Webmin的步骤。Webmin是领先的开源基于Web的Linux/Unix系统管理控制面板。
使用Webmin，我们可以设置用户帐户，管理Apache Web服务器，DNS服务器，samba和文件配置，电子邮件服务器，本地/远程文件系统，程序包管理，管理数据库服务器等。
在RHEL 8/CentOS 8上安装Webmin
在本节中，我们将考虑在RHEL 8上安装Webmin的两种方法。
但首先，安装Perl和必需的依赖项。
sudo yum -y install @perl
方法1：从YUM存储库在RHEL/CentOS 8上安装Webmin
将存储库内容添加到RHEL/CentOS 8系统。
sudo tee /etc/yum.repos.d/webmin.repo<<EOF [Webmin] name=Webmin Distribution Neutral baseurl=https://download.webmin.com/download/yum enabled=1 EOF
然后导入存储库GPG密钥：
sudo rpm --import http://www.webmin.com/jcameron-key.asc
然后使用yum软件包管理器安装webmin。
sudo dnf install webmin
按y接受安装：
Webmin Distribution Neutral 2.9 MB/s | 11 MB 00:03 Last metadata expiration check: 0:00:04 ago on Fri 04 Oct 2019 08:37:07 AM EAT. Dependencies resolved. =================================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================================== Installing: webmin noarch 1.930-1 Webmin 22 M Installing dependencies: perl-Encode-Detect x86_64 1.01-28.el8 AppStream 90 k Transaction Summary =================================================================================================================================================== Install 2 Packages Total download size: 22 M Installed size: 79 M Is this ok [y/N]: y
要获取软件包版本和其他详细信息，请使用：
$rpm -qi webmin Name : webmin Version : 1.930 Release : 1 Architecture: noarch Install Date: Fri 04 Oct 2019 08:37:46 AM EAT Group : System/Tools Size : 82197335 License : Freeware Signature : DSA/SHA1, Sun 18 Aug 2019 05:33:13 AM EAT, Key ID d97a3ae911f63c51 Source RPM : webmin-1.930-1.src.rpm Build Date : Sun 18 Aug 2019 05:33:00 AM EAT Build Host : fudu2 Relocations : (not relocatable) Vendor : Jamie Cameron Summary : A web-based administration interface for Unix systems.
方法2：在RHEL 8/CentOS 8上手动安装Webmin
我建议我们通过这种方法在CentOS 8/RHEL 8上安装Webmin，以获取最新版本的Webmin。
访问Webmin版本页面以检查Webmin的最新版本并下载。
sudo yum -y install wget wget http://www.webmin.com/download/webmin-current.tar.gz
解压缩下载的文件
tar xvf webmin-current.tar.gz rm -f webmin-current.tar.gz
将结果文件夹移到
sudo mv webmin* /usr/local/webmin
将工作目录更改为"/usr/local/webmin /"，然后运行Webmin安装程序脚本。
cd /usr/local/webmin/ sudo ./setup.sh
SetConfig文件目录日志文件目录完整系统类型和版本的完整路径Web服务器端口(默认10000)登录名(默认admin)登录密码SSL
参见下面的安装输出。
$sudo ./setup.sh Welcome to the Webmin setup script, version 1.900 * Webmin is a web-based interface that allows Unix-like operating systems and common Unix services to be easily administered. Installing Webmin in /usr/local/webmin … Webmin uses separate directories for configuration files and log files. Unless you want to run multiple versions of Webmin at the same time you can just accept the defaults.

Use your web browser to go to https://rhel8.local:10000/ and login with the name and password you entered previously. Because Webmin uses SSL for encryption only, the certificate it uses is not signed by one of the recognized CAs such as Verisign. When you first connect to the Webmin server, your browser will ask you if you want to accept the certificate presented, as it does not recognize the CA. Say yes.
在CentOS 8/RHEL 8上配置Webmin
为了能够从网络访问Webmin Web界面，我们需要在防火墙中允许TCP端口10000。
sudo firewall-cmd --add-port=10000/tcp --permanent sudo firewall-cmd --reload
访问Webmin界面
现在我们已经在RHEL 8上安装了Webmin，请打开服务器URL/IP地址port10000，例如https://192.168.122.197:10000
如果收到InvalidCertificate警告，请单击"仍然继续"。
使用安装期间指定的用户名及其密码登录
显示的默认页面是系统详细信息的摘要。
从Web界面，我们可以执行许多Linux管理。与此类似的工具是Cockpit。
