centos5.4下Webmin管理系列（一）：webmin的安裝

一、确定CentOS已經安裝，并且所需服務也已成功裝好

    我在192.168.1.250的一台伺服器上安裝了CentOS5.4版本，安裝了Apache+MySQL+Samba+FTP+DNS+DHCP+SQUID等。從inittab中修改啟動級别為3。重新開機後離開機房，使用辦公室裡192.168.1.188的電腦遠端SSH到伺服器。

二、下載下傳WebMin的最新版本，并安裝

    進入www.webmin.com，點選左側download區域中的RPM，複制連結的下載下傳位址，回到pietty終端中：

Webmin is a web-based interface that allows Unix-like operating

systems and common Unix services to be easily administered.

ERROR: The Webmin install script must be run as root

[lk@hd webmin-1.510]$

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):

Perl seems to be installed ok

Operating system name:    CentOS Linux

Operating system version: 5.4

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:

Pre-loaded WebminCore

Webmin has been installed and started successfully. Use your web

browser to go to

  https://hd: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@hd webmin-1.510]#

ok，安裝成功。

現在再思考剛才RPM沒能安裝成功的原因，很可能是非root身份導緻的。

今天重新安裝系統，又重新試了一遍rpm包，安裝成功，注意身份必須是root：
