Inatalar web server y phpmyadmin Centos 7

Update all packages

Once you are logged in to the server run the following command to make sure that all installed packages are up to date

yum -y update

Install LAMP stack

As mention in the requirements section of the tutorial, a LAMP stack (Apache, MySQL/MariaDB and PHP) is required to run phpMyAdmin no the server. We will start with installing Apache web server

yum -y install httpd

After the installation is completed, start the web server and enable it to start upon server boot

systemctl enable httpd

Next, install PHP along with the required PHP extensions

yum -y install php php-common php-mbstring php-gd

And finally, complete the LAMP installation by installing MariaDB database server

yum -y mariadb mariadb-server

Start the service and set it to start on reboot

systemctl start mariadb
systemctl enable mariadb

Run the ‘mysql_secure_installation’ post installation script provided by MariaDB to strengthen the security of the database server and set a root password. You can use the following options:

mysql_secure_installation

Set root password? [Y/n] Y
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y

Install phpMyAdmin

phpMyAdmin is not available in the official CentOS 7 repositories, so we will have to enable the EPEL repository by executing the following command

yum -y install epel-release

Once the EPEL repository is enabled we can proceed with the phpMyAdmin installation

yum -y install phpmyadmin

The package manager will install phpMyAdmin and all necessary dependencies and the installation of phpMyAdmin is completed. You can now access the application and start working on your databases at http://IP_Address/phpmyadmin .

By default phpMyAdmin is only accessible from the localhost. If you want it to be accessible from everywhere or a certain IP address, open its included Apache configuration file and add/edit the following lines accordingly:

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

deberas de agregar manualmente las lineas en negrito exactamente como esta en el siguiente ejemplo(agregalas a mano ya que puede darte error)

<Directory/usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModulemod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #ADD following line:
       Require all granted
       Require ip 127.0.0.1
       Require ip ::1
     </RequireAny></IfModule><IfModule !mod_authz_core.c>
     # Apache 2.2
     #CHANGE following 2 lines:
     Order Allow,Deny
