如何在FreeBSD 12上安装WebMin？
Webmin是一个流行的基于Web的基于Web的系统配置工具，适用于Linux和UNIX系统。
使用Webmin我们可以设置用户帐户，Manager Apache Web服务器，DNS服务器，SAMBA和文件配置，电子邮件服务器，包管理，管理数据库服务器等

在FreeBSD 12上易于安装Webmin。
包可以从二进制存储库安装或者通过从源代码构建。
选择是，但在本教程中，我们将在FreeBSD 12上使用Webmin的二进制安装。

在FreeBSD 12上安装Webmin

带包管理器的FreeBSD船只称为 pkg我们将用于安装Webmin。

首先更新FreeBSD包索引

更新返回成功后，通过运行以下命令，在FreeBSD 12上安装Webmin：

# pkg install webmin

第一次安装WebMin后，我们应该通过以root运行以下命令来配置Webmin：

# /usr/local/lib/webmin/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/lib/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.
 Log file directory [/var/log/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/local/bin/perl): 
 Testing Perl …
 Perl seems to be installed ok
 
 Operating system name:    FreeBSD
 Operating system version: 12.0
 
 Webmin uses its own password protected web server to provide access
 to the administration programs. The setup script needs to know :
 What port to run the web server on. There must not be another
 web server already using this port.
 The login name required to access the web server.
 The password required to access the web server.
 If the webserver should use SSL (if your system supports it).
 Whether to start webmin at boot time. 
 Web server port (default 10000): 
 Login name (default admin): 
 Login password: <Enter admin Password>
 Password again: <Conform admin Password>
 Use SSL (y/n): y

确保我们设置

• 配置文件目录

• 日志文件目录

• Perl的完整路径

• Web服务器端口(默认为10000)

• 登录名(默认admin)

• 登录密码

• SSL选项(是/否)

在FreeBSD 12上启动网民服务

我们已在FreeBSD 12上安装和配置了Webmin。
最后一步是设置Webmin服务开始启动并启动服务。

设置WebMin服务以启动系统引导：

# sysrc webmin_enable="YES"
webmin_enable:  -> YES

上面的命令将添加该行 webmin_enable="YES"到/etc/rc.conf.

要首次启动WebMin，请运行：

# service webmin start
 Starting webmin.
 Cron 15469220631494 missing any time spec

该服务应该在港口10000上倾听

# sockstat -4 -6 |grep 10000
 root     perl       1536  5  tcp4   *:10000               *:*
 root     perl       1536  6  udp4   *:10000               *:*

访问Webmin接口

打开服务器URL/IP地址端口10000，例如，HTTPS://192.168.122.197:10000
