The most common issue that arises for Linux users is to kill or background a process so that other tasks are conducted on the system. In order to kill a process a signal has to be sent using the Linux kill command.

How to kill a linux process using “kill” command?

Step One: Enter the below linux command to get the PID for the running process on your system which you want to kill.

ps myProcess

Once you enter the above command it will return with something similar to the following:

PID TTY TIME CMD
1234 dz07 0:50 edit myBook
1235 dz07 0:47 -csh

Step Two: Enter the following linux kill command to terminate the first process mentioned in the example above:

kill -1 1234

Enter the following command to terminate the second active process:

kill -1 1235

Step Three: It is possible that the kill -1 does not work, in such a case, you will need to use the -9 argument to clear the process from your system. Use the following command:

kill -9 1234
kill -9 1235

Step Four: Instead you can also kill all the instances of a given process by using the killall command. Enter as shown below:

killall <pname>

<pname> refer to the process name.

This tutorial is applicable only on VPS or a Dedicated Server, as it requires root access to the server.

Attimes you are required to offer Root access for a particular account having limited privileges on a server. You must follow the below steps to assign Root Access to a particular user using sudo.

Step 1 : Login to the server as root.

Step 2 : Run the following command :

root@host [~]# visudo

Step 3 : The screen displayed would be of the sudoers file in the vi editor. You must include the belwow line into this file to assign complete root privileges to an account (in our case it is accountname).:

accountname ALL=(ALL) ALL

Step 4 : If you do not intend to offer the complete access but be able to run a particular list of commands, you may create a command alias in your sudoers file, for example:

User_Alias ADMINS = accountname
Cmnd_Alias HTTPD = /etc/init.d/httpd
ADMINS ALL = HTTPD

With this, you should be able to create a group of users whom you can then assign command aliases to. You only need to ensure that the users are separated using a comma (,).

The Cmnd_Alias would show you a list of different commands that the users of a particular Alias can run. You may then choose the user alias and assign the command alias.

The above would ask the user to enter his/er password each time sudo is run. Though if don’t want the system to ask for a password each time, you may replace ADMINS ALL = HTTPD in the last line with the following :

ADMINS ALL = NOPASSWD: HTTPD

Sorry, that domain is already setup (remove it from httpd.conf)

Getting the above error simply means that the domain still exists in the virtualhost in apache configuration file known as httpd.conf . There are two main reasons why it has shown you this error.

Reason One:

It might be possible that the domain you are trying to create is being used as a primary domain for one of the accounts or may be it has been used as an addon domain or parked for other domains and accounts.

Reason Two:

Or it may be possible that you are facing some technical issues such as the addon, parked or the primary domain is not removed completely from the system after using the removing function.

If the error is due to the first reason, you can easily remove the domain name from the cPanel account and even if it is not removed and come up with the following error:

Error from park wrapper: Sorry, you do not control the domain

Follow the steps given below:

First you should find out who owns the domain, enter the following command:

/scripts/whoowns example.com

Even if it didn’t show any results, enter the following command string:

grep example.com /var/cpanel/users/*

You will get the result something like the following:

root@server [~]# grep example.com /var/cpanel/users/*
/var/cpanel/users/exam:XDNS1=example.com

As you can see, we could easily find the owner of the domain (example.com), the next step is to edit the following files with the corresponding user and remove the lines associated with the domain (example.com) you have problem with.

/var/named/example.com.db
Remove the virtualhost for example.com from /etc/httpd/conf/httpd.conf
/var/cpanel/users/username [remove entries related to domain]
/etc/userdomains
/etc/localdomains
vim /etc/named.conf [remove entries related to domain]
Remove DNS entry in WHM
Run /scripts/updateuserdomains as root on the server

That’s it!

How to create backup of Individual cPanel Account via SSH?

Step 1: Log-in to the SSH as Root user.

Step 2: Enter the following command string on the command line interface:

/scripts/pkgacct username

[Note: The account backup will be created in the current directory you are in.]

How to Restore the Individual cPanel Account via SSH?

Step 1: To restore the cPanel account backups, enter the following command

/scripts/restorepkg username

[Note: In order to restore the data, you need to be in the directory where the backup file is stored.]

This is the easiest way to backup and restore individual cPanel web hosting accounts via command line interface.

Step 1 : Log into cPanel

Step 2 : Go to phpMyAdmin and choose the database and the table that you intend to copy

Step 3 : Go to the option titled “Operations” listed amongst the other tabs

Step 4 : Locate the box titled “Copy table to (database,table): ”

Step 5 : There are two options you may choose from ie. either create a copy of the table to the current database (usually gets selected by default) OR copy the table to a different database

Step 6 : Choose the database name from the drop-box and the name of the table to copy the structure and / or data into.

You are required to choose between the following options before proceeding any further :

• Structure only – Selecting this option would only create a copy of the table and its name. You must note that the data wouldn’t be copied in this case.

• Structure and data – Choosing this option would allow you to copy the table along-with its name, but would also copy the data it contains to the destination you choose further in the process ie. INSERT INTO >> SELECT * FROM …
• Data only – Clicking the radio button would only copy the data to the destination.

Furthermore, you are offered the option to choose whether you wish to drop the table that you are copying to before creating the table and copying the data. This runs a DROP TABLE IF EXISTS query for the copy of the table, not the original. You would not notice any change if you’ve chosen data only copy.

Then you’d have the option to choose to copy the auto increment value. This isn’t a default function, and you’d need to check it manually. The auto increment value will end up being whatever it would be after the INSERT INTO query is done. Checking the box would activate the CREATE TABLE syntax which would then include the auto increment value from the original table.

Lastly, you can see the option termed “Switch to copied table ”, as the title suggests you’d be switched over to the copied table once the queries are completed. If you leave it unchecked, the resulting page will still be looking at the original table; if checked it will change to the copied database (if applicable) and table.

httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName

To initiate the the process, we’d first check the IpTables

You need to be careful with the primary step ie. before you install a web server. This is to ensure that browser is capable of reaching it.

Usually, if you have a firewall running on a server, it may carry out its task of blocking traffic to ports 80 and 443 which are usually used for regular and secure connections respectively. So, you must first check the firewall rules using the below command :

sudo /sbin/iptables -L

Check whether the ports 80 and 443 are open. Well, if you do not have a firewall installed on a server yet, there is no question of making any changes to it.

If you find that the ports are closed the following rules should be set in iptables configuration:

iptables -I INPUT -p tcp –dport 80 -m state –state NEW,ESTABLISHED -j ACCEPT
iptables -I OUTPUT -p tcp –sport 80 -m state –state ESTABLISHED -j ACCEPT
iptables -I INPUT -p tcp –dport 443 -m state –state NEW,ESTABLISHED -j ACCEPT
iptables -I OUTPUT -p tcp –sport 443 -m state –state ESTABLISHED -j ACCEPT

How to Install Apache on Fedora ?

The procedure to Install a basic apache is simple, use the following command for the same :

sudo yum install httpd mod_ssl

This command would install apache and couple other packages to support few of the required option.

Setting the ServerName

You may probably encounter a warning such as “httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName”. Such a warning is usually shown by “httpd” as it is a default name of an apache process when it’s running, therefore you must look for in a ps list or top.

To get past this warning you are first of all required to create a “custom” directory in apache’s configuration directory. The following command should help you do that :

sudo mkdir /etc/httpd/conf/custom

Now create a config file to store your server name:

sudo nano /etc/httpd/conf/custom/preferredserver_name.conf

You must now include the below line into the servername.conf file

ServerName preferredserver_name

NOTE : You must replace the “preferredserver_name” with the name of your choice. Make sure that you do not use domain name as we’d be using it to create virtual hosts later.

Then, you must save the file.

Now, make amendments to the the main apache config file, use the following command to access it:

sudo nano /etc/httpd/conf/httpd.conf

Scroll down to the end and insert the below code:

Include /etc/httpd/conf/custom/*.conf

Save the changes made to httpd.conf.

This completes the installation of apache.

Use the below command to start automatically upon reboot.

sudo /sbin/chkconfig httpd on

Make sure that the ServerName is included in the httpd.conf file and the host name is correctly specified:

hostname preferredserver_name

Once the server is Rebooted, you shouldn’t see the Warning message again.

Basically, there are many services required on servers to run the background such as DB Server, Firewall, Web Server, DNS System, Mail Server, etc… Due to these various services, it is very much essential to know the exact procedure of starting, stopping and restarting the services.

The procedure of start, stop and restart the services may change as per the linux distributions. Here in this article we are going to see how to start, stop and restart services in CentOS Dedicated Server.

There are two different methods through which you can start, stop and restart any desired service:

How to Start a Service?

First Method:
/etc/init.d/service-name start

Second Method:
service service-name start

How to Stop a service?

First Method:
/etc/init.d/service-name stop

Second Method:
service service-name stop

How to Check the Status of a Service: (whether it is running or not)

First Method:
/etc/init.d/service-name status

Second Method:
service service-name status

How to restart a service on dedicated server?

First Method:
/etc/init.d/service-name restart

Second Method:
service service-name restart

It might be possible that few services may have extra command settings. To find the available ones, enter:

First Method:
/etc/init.d/rsync [start, stop, reload, force-reload, restart, status]

Second Method:
service rsync
