Ready , installed and started the FTP service. Now we can perform tests to see the operation of the service. It’s time to create a username and password to connect to your FTP server , for this type :

useradd

Example:

# useradd test

Let’s create the password for the user. which in my case is test :

# passwd test

You will be asked for you to enter a password and click on you are asked to repeat the password. After that, we have created the username and password released to access the FTP server.

Now we switch to the user created . For this type primarily the following command to log in as user test :

# su - test

Create a folder within this user :

# mkdir Softwares

Remember that Linux is case sensitive, so if you type the first letter capitalized , remember to type correctly later.
Okay, now we need to know the number of IP address that is on your computer in order to make the FTP connection.

CentOS 7 / RHEL 7 : Reset / Recover forgotten root password

In this post we will learn, how to reset / recover forgotten root password on CentOS 7 / RHEL 7 (Red Hat Enterprise Linux 7). On RHEL 5/6 or CentOS 5/6 series , the method of resetting forgotten root password was same. In latest RHEL 7 / CentOS 7 this time we have found some difference in steps to reset the forgotten root password.

Earlier, root password were used to recover from runlevel in case the boot loader password is not set.

Reset / Recover forgotten root password on CentOS 7 / RHEL 7

Follow the given below procedure to reset forgotten root password.

Step 1: Reboot or start the system, edit grub2

Restart/start the system and on getting GRUB 2 boot screen, first press ESC key so that screen get stopped. Then press e key for editing

vbox-1

Step 2: Initialize the /bin/sh

Now in next screen, scroll down with the help of arrow key and search for any of these two keyword linux16 or linuxefi on UEFI systems.In our case, we have linux16.

Disable rhgb and quiet parameters in order to enable system messages.

In first screenshot you can see, we first scrolldown to line starting with keyword called linux16 . Now remove the parameter rhgb and quiet .

root-passwd-2

In second screenshot you can see, we have removed the rhgb and quiet parameter
Add the below given parameter at the end of line, to initialize the sh shell.

init=/bin/sh

Now press CTRL with x keyword to boot the system. .

root-password-3

Step 3: Remount / root partition , reset root password and autorelable

The filesystem will be in read only mode, hence run the below given command so that you can write on filesystem

mount -o remount, rw /

Now reset root password with given below command

passwd root

Reconfirm the root password.

NOTE: In case system is not writable, the passwd tool fails with the following error:
Authentication token manipulation error

Now run the below given command for relabeling the SELINUX

touch /.autorelabel

Now restart the system. You can use any one of the command.

exec /sbin/init

OR

exec /sbin/reboot

vbox-6

You will see the system is going to reboot and stuck for a short time. Just wait for a few seconds or minute. Keep pay attention that the screen is stopped when SELIUX relabeling info message appeared on screen.
After a few moment, you will see at the bottom of screen some numerical percentage is running. It states about the completion of selinux relabeling in percentage. After completing 100% , the system will be rebooted.

vbox-7

After successful booting, you can use your new root password for login into system.

vbox-8

That is all!

Install Apache, PHP And MySQL On CentOS 7 (LAMP)

This tutorial shows how you can install an Apache2 webserver on a CentOS 7.0 server with PHP5 support (mod_php) and MySQL support. LAMP is short for Linux, Apache, MySQL, PHP.

1 Preliminary Note

In this tutorial, I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.
I will add EPEL-7 repo here to install latest phpMyAdmin as follows:

rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

2 Installing MySQL 5

To install MySQL, we do install mariadb like this:

yum -y install mariadb-server mariadb

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

systemctl start mariadb.service
systemctl enable mariadb.service

Set passwords for the MySQL root account:

mysql_secure_installation

Return:

[root@server1 ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): <--ENTER
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n]
New password: <--yourmariadbpassword
Re-enter new password: <--yourmariadbpassword
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <--ENTER
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <--ENTER
... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <--ENTER
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <--ENTER
... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
[root@server1 ~]#

3 Installing Apache2

CentOS 7.0 ships with apache 2.4. Apache2 is directly available as a CentOS 7.0 package, therefore we can install it like this:

yum -y install httpd

Return:

[root@server1 ~]# yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: ftp.plusline.de
* extras: mirror.23media.de
* updates: mirror.23media.de
Package httpd-2.4.6-17.el7.centos.1.x86_64 already installed and latest version
Nothing to do
[root@server1 ~]#

By default apache will be installed, if-not then please install it as shown above
Now configure your system to start Apache at boot time…

systemctl start httpd.service
systemctl enable httpd.service

In CentOS 7.0 uses Firewall-cmd, so I will customize it to allow external access to port 80 (http) and 443 (https).

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Now direct your browser to http://192.168.0.100, and you should see the Apache2 placeholder page:

4 Installing PHP5

We can install PHP5 and the Apache PHP5 module as follows:

yum -y install php

We must restart Apache afterwards:

systemctl restart httpd.service

5 Testing PHP5 / Getting Details About Your PHP5 Installation

The document root of the default website is /var/www/html. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.

vi /var/www/html/info.php

Code:

<?php
phpinfo();
?>

Now we call that file in a browser (e.g. http://192.168.0.100/info.php):

2

As you see, PHP5 is working, and it’s working through the Apache 2.0 Handler, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don’t have MySQL support in PHP5 yet.

6 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It’s a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

yum search php

Pick the ones you need and install them like this:

yum -y install php-mysql

In the next step I will install some common PHP modules that are required by CMS Systems like WordPress, Joomla and Drupal:

yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel

Now restart Apache2:

systemctl restart httpd.service

Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules like curl etc there.:

7 phpMyAdmin installation

phpMyAdmin is a web interface through which you can manage your MySQL databases.
phpMyAdmin can now be installed as follows:

yum install phpMyAdmin

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory “/usr/share/phpmyadmin”> stanza):

vi /etc/httpd/conf.d/phpMyAdmin.conf

Code:

[...]
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

#<Directory /usr/share/phpMyAdmin/>
# <IfModule mod_authz_core.c>
# # Apache 2.4
# <RequireAny>
# Require ip 127.0.0.1
# Require ip ::1
# </RequireAny>
# </IfModule>
# <IfModule !mod_authz_core.c>
# # Apache 2.2
# Order Deny,Allow
# Deny from All
# Allow from 127.0.0.1
# Allow from ::1
# </IfModule>
#</Directory>
<Directory /usr/share/phpMyAdmin/>
Options none
AllowOverride Limit
Require all granted
</Directory>

[...]

Next we change the authentication in phpMyAdmin from cookie to http:

vi /etc/phpMyAdmin/config.inc.php

Code:

[...]
$cfg['Servers'][$i]['auth_type'] = 'http'; // Authentication method (config, http or cookie based)?
[...]

Restart Apache:

systemctl restart httpd.service

Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:
