How to create a FTP user with specific /dir/ access only on a Centos / linux installation

I currently have SFTP access to the server via my root user, but am now trying to create a new user with FTP access to a specific directory only on the server, I've done the following:

Before that, please check and confirm 'vsftpd' service already installed. you can check those using below commands.

 #sudo yum install httpd

Now, below commands for new user creation with different home directory.

1. mkdir /var/www/mydomain.com
2. mkdir /var/www/mydomain.com/html
3. useradd <-username>
4. passwd <-username>
5. chown –R <-username> /var/www/mydomain.com
5. groupadd <-groupname>
6. gpasswd -a <-username> <-groupname>
7. chgrp -R <-groupname> /var/www/mydomain.com
8. chmod -R g+rw /var/www/mydomain.com

You have to add the following option on the vsftpd.conf file

chroot_local_user=YES

How To Install and phpMyAdmin in Linux

Step One — Install a LAMP Stack

Before we can install phpMyAdmin, we need to install Apache, MySQL, and PHP on our server. Together, along with the underlying operating system, this is known as a LAMP stack (Linux, Apache, MySQL, PHP). We can go ahead and install the necessary components from the default yum repositories by typing:

# sudo yum install httpd mysql-server php php-mysql

A web server, database server, and dynamic processing language will be installed on your server and ready to use.

Step Two — Check the LAMP Stack

Next, we need to check all the components that we have just installed. Start the Web Server and MySQL server and Check all of them using below commands

#service httpd status

#service mysqld status

Step Three — Install phpMyAdmin

Now, we are ready to install the phpMyAdmin package. This software is not available in the CentOS 6 default repositories. However, it is avialable in the EPEL repos (Extra Packages for Enterprise Linux). We can add access to the EPEL repositories to our system by typing:

#sudo yum install epel-release

After accepting the new repository, you can install the phpMyAdmin package by typing:

#sudo yum install phpmyadmin

This will install phpMyAdmin. We still must configure it though.

Step Four — Configure phpMyAdmin

Configure Apache Files: The phpMyAdmin package installs an Apache Virtual Host file that is used to configure web access. Open the file with the following command:

#vim /etc/httpd/conf.d/phpMyAdmin.conf

.....
Require ip your_workstation_IP_address
.....
Allow from your_workstation_IP_address
.....
Require ip your_workstation_IP_address
.....
Allow from your_workstation_IP_address

Save and close the file. You need to restart the server with the following command:

#sudo service httpd restart

Point your web browser to your VPS IP address followed by "/phpmyadmin"

#http://VPS_IP_address/phpmyadmin

After you provide the requested credentials, you will have access to the phpMyAdmin interface:

Bringing Up Interface Eth0: Error: No Suitable Device Found: No Device Found for Connection ‘System Eth0’

The problem begins when, after cloning a virtual machine, the eth0 device cannot be found by the kernel. You will normally notice an error during boot similar to: “Bringing up Interface eth0: Error: No suitable device found: no device found for connection ‘System eth0’.

Bringing up Interface eth0: Error: No suitable device found: no device found for connection ‘System eth0’

As I mentioned above, this is caused when the new virtual machine is created. VMware has assigned an Ethernet adapter to the virtual machine with a different MAC address than what the source VM was using.

ifconfig shows eth1 instead of eth0

Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 File
With this information, grab the HWaddr, we will then edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file and change the HWADDR parameter to the MAC address that you found in one of the 2 steps above.

Edit the MAC address in /etc/sysconfig/network-scripts/ifcfg-eth0

Restart the Network Service:

# service network restart
