Crucial Paradigm

Login  as root and run the following command:

wget http://prdownloads.sourceforge.net/webadmin/webmin-1.350-1.noarch.rpm

Once finished run:

rpm -U webmin-1.350-1.noarch.rpm

The rest of the install will be done automatically to the directory /usr/libexec/webmin, the administration username set to root and the password to your current root password. You should now be able to login to Webmin at the URL http://localhost:10000/ .

Webmin install complete. You can now login to https://hostname.domain:10000/
as root with your root password.

NOTE: the default login and password is your root and root password. this is the same login you used with you ssh to your server or whatever your root password is, so your login will be like this:

Username: root
Password: xxxx (what ever your root password is)

Have you encountered the following error while trying to compile applications from source on your VPS or server?

-bash: ./configure: No such file or directory

To fix this on CentOS, just install make:

yum install make

This article describes how to configure a new partition from free space on a dedicated server, or a virtual machine with full virtualization (such as VMware or XenServer):

1. Verify the partitions available on the server: fdisk -l
2. Choose which device you wish to use (such as /dev/sda or /dev/sdb)
3. Run fdisk /dev/sdX (where X is the device you would like to add the partition to)
4. Type ‘n’ to create a new partition.
5. Specify where you would like the partition to end and start.  You can set the number of MB of the partition instead of the end cylinder.  For example:  +1000M
6. Type ‘p’ to view the partition, and type ‘w’ to save the partition
7. Run the command ‘partprobe’ to have the OS detect the new partition table.  If it still does not detect the partition table, you might need a reboot.
8. Format the partition by doing:  ‘mke2fs -j /dev/sdaX’ – where X is the number of the partition you have created.
9. Create a directory where you wish to mount the new drive, for example: /newpartition.  ‘mkdir -p /newpartition’
10. To mount, you can use the following command: ‘mount /dev/sdaX /newpartition’
11. If you would like the drive to be mounted automatically each time you boot, add the following to /etc/fstab: ‘/dev/sdaX /newpartition ext3 defaults 1 2′

Make sure you have backups before you perform any formatting, or creating new partitions!

This is a the quick easy way to get lmsensors installed on your server (without having to compile kernel modules, etc):

1. Run: yum install sensor
2. Run: sensors-detect (to configure sensor automatically)
3. Run: restart senors
4. sensors

With lm_sensors you can view system temperature, fan speeds, voltages, etc.  Its a great way to monitor some of the finer aspects of your server.
