How is the lamp environment built? Detailed process of lamp environment construction

This article introduces you to the details of the lamp environment to build the detailed process, there is a certain reference value, the need for a friend can refer to, I hope to help you.

After starting to minimize the installation of CentOS 7, directly enter the Ifconfig command, prompting "ifconfig command not found", stating that the minimal installation does not install the relevant software, we can use IP addr instead of ifconfig to view the NIC details, or We can install the Ifconfig command via the Yum install Net-tools and enter two y during the installation process to complete the installation.

First, Apache

yum install httpdInstalling Apache

Turn on the Apache service and set the service to start automatically when the system starts:
systemctl start httpd.service
systemctl enable httpd.service

In order to be able to access the Web server externally, the HTTP (80) and HTTPS (443) ports must be opened in the firewall. The default firewall on CentOS is FIREWALLD and can be configured with the Firewalld-cmd command.
firewall-cmd --permanent --zone = public --add-service = http
firewall-cmd --permanent --zone = public --add-service = https
firewall-cmd --reloadRestart Firewalld

To detect if the Apache service is open:
systemctl status httpd.service

Second, mysql/mariadb

MARIADB database management System is a branch of MySQL, mainly by the open source community in the maintenance, the use of GPL license.

One of the reasons for developing this branch is that after Oracle acquired MySQL, there is a potential risk of shutting MySQL out of the source, so the community uses a branching approach to avoid this risk.

MARIADB is designed to be fully compatible with MySQL, including APIs and command lines, and is currently the most watched MySQL database derivative, and is also considered a replacement for the open source database MySQL.

Here we use MARIADB instead of mysql,mysql installation and operation method is roughly similar.
When installing, replace the mariadb with MySQL;
Start, stop service, view status, change Mariadb.service to Mysql.service.

yum -y install mariadb-server mariadbInstalling MARIADB

Turn on the MARIADB service and set the service to start automatically when the system starts:
systemctl start mariadb.service
systemctl enable mariadb.service

To set the password for the MySQL root account:
mysql_secure_installation

Note:running all PARTS of this SCRIPT are 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 CurrentPassword for the root user. If you ' ve just installed MariaDB, Andyou Haven ' t set the root password yet, the password would be a blank,so you should just Press ENTER here. Enter current password to root (enter for none)://Enter the root user password, direct enter OK, successfully used password, moving on ... Setting The root password ensures that nobody can log into the Mariadbroot user without the proper authorisation. Set root Password? [y/n] New Password://Enter password re-enter new password://Confirm password Password updated successfully! Reloading privilege tables. ... success!  By default, a MariaDB installation had an anonymous user, allowing Anyoneto log into MariaDB without had to had a user  Account created Forthem.  This was intended only for testing, and the Installationgo a bit smoother. You should remove them bEfore moving into aproduction environment. Remove anonymous users? [y/n]//Delete anonymous user, enter ... success!  Normally, Root should only is allowed to connect from ' localhost '. Thisensures that someone cannot guess at the root of password from the network. Disallow Root login remotely? [y/n]//Do not allow root users to Telnet, enter ... success!  By default, the MariaDB comes with a database named ' Test ' anyone canaccess.

In order for the database to be associated with PHP, we also need to install Php-mysql:
yum install php-mysqlThe installation process enters Y to complete the installation

systemctl restart httpd.serviceAfter you install PHP, restart the Apache service.

Test that PHP is not installed properly:
vi /var/www/html/index.phpCreate a new PHP file, fill in the following content

<?phpphpinfo ();? >

Add/info.php to the previous URL and see the following interface to indicate that the installation was successful.
