instal dan konfigurasi webmin di centos

Webmin adalah suatu antarmuka berbasis web untuk melakukan administrasi sistem pada Unix/Linux. Dengan webmin, kita dapat mengatur setting user account, file sharing, DNS, Apache, dan masih banyak lagi. Webmin mengandung skrip CGI yang secara langsung melakukan update terhadap file-file sistem seperti /etc/passwd dan /etc/inetd.conf. Karena berbasis web, maka webmin bisa diakses dari berbagai distro dan sistem operasi lain, seperti Windows dan Macintosh.
Instalasi Webmin:

1. Download paket webmin di website http://www.webmin.com. Di sana tersedia berbagai macam format file, seperti tar,gz, rpm, pkg.gz, deb dan zip.

2. Pastikan sistem Andah sudah terinstall perl versi 5. Untuk mengecek apakah sudah terinstall Perl versi 5, gunakan perintah “perl -v”

[root@bagelen] [/usr/src]# perl -v

This is perl, v5.8.8 built for i386-linux-thread-multi

Jika belum, maka install dl perl module Net::SSLeay.

3. Ekstrak file webmin-1.450.tar.gz. Sehingga akan muncul direktori webmin-1.450. Masuk ke direktori webmin-1.450

[root@bagelen] [/usr/src]# tar -xzvf webmin-1.450.tar.gz
[root@bagelen] [/usr/src]# cd webmin-1.450

4. Jalankan file setup.sh, untuk menjalankan setup.sh harus sebagai root.

[root@bagelen] [/usr/src/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 /usr/src/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]: [tekan enter]
Log file directory [/var/webmin]: [tekan enter]

***********************************************************************
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): admin
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://bagelen.net: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.

Keterangan :

Config file directory : tempat semua file konfigurasi Webmin disimpan, defaultnya /etc/webmin/

Log file directory : direktori dimana log webmin, defaultnya /var/webmin/

Full path to perl (default /usr/bin/perl)

Web server port (default 10000): port yang digunakan untuk webmin

Login name (default admin): username yang dipakai untuk menjalankan webmin

Login password: passwordnya

Password again: passwordnya

Use SSL (y/n): pertanyaan ini ada jika sudah terinstall library Perl SSL.

Start Webmin at boot time (y/n): menjalankan secara otomatis pada saat boot.
Nah, sekarang sudah selesai menginstall webmin dalam server. Untuk mencoba webmin, buka browser dan ketikkan : http://namaserver:10000/, sebagai contoh http://bagelen.net:10000/

Karena saya install dengan SSL maka alamat seharusnya diakses : https://bagelen.net:10000/
