1. 前言
在本教程中，我們將介紹如何在CentOS8或者RHEL8上安裝Webmin。Webmin是領先的基於web的開源Linux/Unix系統管理控制面板。
使用Webmin，您可以設置用戶帳戶，管理Apache web服務器，DNS服務器，samba和文件配置，電子郵件服務器，本地/遠程文件系統，軟件包管理，管理數據庫服務器等。
如何在CentOS8或者RHEL8上安裝Webmin
2. 在CentOS8或者RHEL8上安裝Webmin
在本節中，我們將討論在CentOS8或者RHEL8上安裝Webmin的兩種方法。
但首先，安裝Perl和所需的依賴項。
sudo yum -y install @perl
2.1 在CentOS8或者RHEL8上從yum源倉庫中安裝Webmin
sudo tee /etc/yum.repos.d/webmin.repo<[Webmin]
name=Webmin Distribution Neutral
baseurl=https://download.webmin.com/download/yum
enabled=1
EOF
導入軟件倉庫的GPG key：
sudo rpm --import http://www.webmin.com/jcameron-key.asc
然後使用yum包管理器安裝webmin。
sudo dnf install webmin
按y接受安裝

2.2 方法2:手動在RHEL8或者CentOS 8上安裝Webmin
我建議你用這個方法在CentOS8或者RHEL8上安裝Webmin，以獲得最新的Webmin安裝。
訪問Webmin發佈頁面，查看最新發布的Webmin並下載。
sudo yum -y install wget
wget http://www.webmin.com/download/webmin-current.tar.gz
解壓剛剛下載的文件：
tar xvf webmin-current.tar.gz
rm -f webmin-current.tar.gz
移動到相應的目錄：
sudo mv webmin* /usr/local/webmin
將工作目錄更改為/usr/local/webmin/並運行Webmin安裝程序腳本。
cd /usr/local/webmin/
sudo ./setup.sh
設置
- 配置文件目錄
- 日誌文件目錄
- 完整的Perl路徑
- 操作系統-類型和版本
- Web服務器端口(默認10000)
- 登錄名(默認管理員)
- 登錄密碼
- SSL
輸出類似於以下的內容：
sudo ./setup.sh
Welcome to the Webmin setup>
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.
Config file directory [/etc/webmin]:
Log file directory [/var/webmin]:
Webmin is written entirely in Perl. Please enter the full path to the
Perl 5 interpreter on your system.
Full path to perl (default /usr/bin/perl):
Testing Perl …
Perl seems to be installed ok

type and version you are running. Please select your system type by

Webmin has been installed and started successfully. 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.
3. 在CentOS8或RHEL8上配置webmin
為了能夠從網絡訪問Webmin Web界面，您需要允許防火牆中的TCP端口10000。
sudo firewall-cmd --add-port=10000/tcp --permanent
sudo firewall-cmd --reload
訪問Webmin界面：
現在你已經在CentOS8或者RHEL8上安裝了Webmin，打開你的服務器URL或者IP地址端口10000。比如https://192.168.122.197:10000
如果提示“Invalid Certificate”，點擊Continue Anyway
