对于经常研究Linux的用户，Linux是一个成熟而稳定的网络操作系统，不过Linux给大家的印象就是一大堆的命令字符以及黑黑的显示屏。虽然现在Linux桌面版有了长足的进步，界面已和Windows不相上下了．
但对于Linux服务器来说，恐怕没有几个管理员会愿意装X-Windows程序．因此大部份的Linux服务器都是基于字符界面的．对于刚刚接触Unix的系统管理员来说，正确高效地完成各种关键的系统配置简直是一件不可能的任务。
即使是一个很有经验的Unix的管理员，也常常会为某些复杂的配置文件的格式而苦恼。因此拥有一个Unix上的GUI管理工具一直是广大Unix爱好者的美好愿望，当然前题是不用安装X-Windows程序．Webmin的出现实现了我们的想法．一起去看看这个程序的强大功能吧．
简介：
Webmin是一个基于Web的Unix系统管理工具。管理员通过浏览器访问Webmin的各种管理功能并完成相应的管理动作。目前Webmin支持绝大多数的Unix系统，这些系统除了各种版本的linux以为还包括：AIX、HPUX、Solaris、Unixware、Irix和FreeBSD等．
一、机器的环境如下：
- [root@localhost ~]# uname -r
- 2.6.18-028stab057.4
- [root@localhost ~]# cat /etc/redhat-release
- CentOS release 5 (Final)
- [root@localhost ~]# ip ad sh
- 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
- link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
- inet 127.0.0.1/8 scope host lo
- inet6 ::1/128 scope host
- valid_lft forever preferred_lft forever
- 3: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue
- link/void
- inet 127.0.0.1/32 scope host venet0
- inet 172.20.51.154/32 brd 172.20.51.154 scope global venet0:0
在安装webmin时要求系统必须有Perl支持，如果启用ssl的话还须有openssl及perl-net-ssleasy模块的支持
二、检查模块：
- [root@localhost ~]# rpm -qa |grep perl
- mod_perl-2.0.2-6.1
- perl-Net-SSLeay-1.32-1.el5.rf
- perl-5.8.8-10
- perl-BSD-Resource-1.28-1.fc6.1
- perl-DBI-1.52-1.fc6
- perl-DBD-MySQL-3.0007-1.fc6
- perl-String-CRC32-1.4-2.fc6
- [root@localhost ~]# rpm -qa |grep openssl
- openssl-0.9.8b-8.3.el5
三、安装模块：
[root@localhost ~]# rpm -ivh perl-Net-SSLeay-1.32-1.el5.rf.i386.rpm
这个rpm包可以在http://dag.wieers.com/rpm/packages/perl-Net-SSLeay/这个中下载
四、解压webmin
[root@localhost ~]# tar xvfz webmin-1.450.tar.gz
五、安装webmin
- [root@localhost ~]# cd webmin-1.450
- [root@localhost webmin-1.450]# ./setup.sh
- ***********************************************************************
- * Welcome to the Webmin setup script, version 1.450 *
- ***********************************************************************
- Webmin is a web-based interface that allows Unix-like operating
- systems and common Unix services to be easily administered.
- Installing Webmin in /root/webmin-1.450 ...
- ***********************************************************************
- 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]: /usr/local/webmin
- Log file directory [/var/webmin]: /usr/local/webmin/log
- ***********************************************************************
- 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
- ***********************************************************************
- Operating system name: CentOS Linux
- Operating system version: 5
- ***********************************************************************
- 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): root
- Login password:
- Password again:
- Use SSL (y/n): y
- Start Webmin at boot time (y/n): y

- Webmin has been installed and started successfully. Use your web
- browser to go to
- https://localhost.localdomain: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.
- [root@localhost webmin-1.450]#
六、测试运行
如果在安装的过程中选取默认的设置并启用了SSL的话，那么直接输入https://ip:10000就可以进去了，我这里ip是172.20.51.154，所以输入https://172.20.51.154:10000
输入你的用户名和密码，就可以体验一下了。以上就是图文方式管理Linux服务器(Webmin)讲解。
