2.6 Start-up configuration
2.6.1 Set Global Server Name to Suppress Syntax Warnings
You need to add a single line to the /etc/apache2/apache2.conf file to suppress above warning
message. While harmless, if you do not set Server Name globally, you will receive the following
warning when checking your Apache configuration for syntax errors:
sudo apache2ctl configtest
Output
AH00558: apache2: Could not reliably determine the server''s fully
qualified domain name, using 127.0.1.1. Set the ''Server Name'' directive
globally to suppress this message
Syntax OK

Open up the main configuration file with your text edit:
sudo nano /etc/apache2/apache2.conf
Inside, at the bottom of the file, add a Server Name directive, pointing to your primary domain
name. If you do not have a domain name associated with your server, you can use your server''s
public IP address:
/etc/apache2/apache2.conf
. . .
ServerName server_domain_or_IP
Save and close the file when you are finished.
Next, check for syntax errors by typing:
sudo apache2ctl configtest
Since we added the global Server Name directive, all you should see is:
Output
Syntax OK
Restart Apache to implement your changes:
sudo systemctl restart apache2
2.6.2 Check apache status
Issue following command to check apache status.
sudo systemctl status apache2
2.6.3 Available options for PHP modules and libraries
Use the arrow keys to scroll up and down, and q to quit.
apt-cache search php- | less
To get more information about what each module does, you can either search the internet, or
you can look at the long description of the package by typing:
apt-cache show package_name
2.6.4 Test php on your server
The address you want to visit will be:

4 Setup DNS
Once you have your LAMP/LEMP stack installed, your server is ready to start serving web
content. However, right now, you can only access it using the server''s public IP address.
You can set up a domain name (like example.com) so that visitors can access your site easier.
You''ll need to purchase your desired domain name from a domain name registrar.

6 Apache v.s. Nginx
Both Apache and Nginx are powerful, flexible, and capable. Deciding which server is best for
you are largely a function of evaluating your specific requirements and testing with the patterns
that you expect to see.
There are differences between these projects that have a very real impact on the raw
performance, capabilities, and the implementation time necessary to get each solution up and
running. However, these usually are the result of a series of trade-offs that should not be
casually dismissed. In the end, there is no one-size-fits-all web server, so use the solution that
best aligns with your objectives.

7 Change Default Password
To change (or update) mysql root password, you need to use the following command:
$ mysqladmin -u root -p''oldpassword'' password newpass
For example, if the old password is abc, you can set the new password to 123456, enter:
$ mysqladmin -u root -p''abc'' password ''123456''
Note:123456 password is used for demonstration purpose only. You must select a strong
password. It is an important protection to help you have safer MySQL database transactions.

8 Access phpMyAdmin on CentOS
In order to access phpMyAdmin, we will need to modify apache configuration a bit to get it to
work correctly.
Open the file in your text editor now so that we can make a few changes:
sudo vim /etc/httpd/conf.d/phpMyAdmin.conf
Inside, we see some directory blocks with some conditional logic to explain the access policy for
our directory. There are two distinct directories that are defined, and within these, configurations
that will be valid for both Apache 2.2 and Apache 2.4 (which we are running).
Currently, this setup is configured to deny access to any connection not being made from the
server itself. Since we are working on our server remotely, we need to modify some lines to
specify the IP address of your home connection.
Change any lines that read Require ip 127.0.0.1 or Allow from 127.0.0.1 to refer to
your home connection''s IP address. If you need help finding the IP address of your home
connection, check out the next section. There should be four locations in the file that must be
changed:
. . .
Require ip your_workstation_IP_address
. . .
Allow from your_workstation_IP_address
. . .
Require ip your_workstation_IP_address
. . .
Allow from your_workstation_IP_address
. . .
When you are finished, restart the Apache web server to implement your modifications by typing:
sudo systemctl restart httpd.service
With that, our phpMyAdmin installation is now operational. To access the interface, go to your
server''s domain name or public IP address followed by /phpMyAdmin, in your web browser:
http://server_domain_or_IP/phpMyAdmin

To sign in, use a username/password pair of a valid MariaDB user. The root user and the
MariaDB administrative password is a good choice to get started. You will then be able to
access the administrative interface:
