1.Apache download and install to start

Switch to the root user

root$ su
root$ 密码：
root$ 
//安装
root$ yum install httpd -y
//设置开机自启动
root$ systemctl enable httpd
//启动httpd
root$ systemctl start httpd

After the start apache installation is complete, the browser to http: // localhost or a remote computer or http://127.0.0.1 browser enter http: // ip remote server to access the apache home, if there is normal

Note that if remote access, the need to shut down the server-side firewall and the firewall open port 80, otherwise access will fail.

Turn off the firewall command

root$ systemctl stop firewalld

Set up a firewall port 80 open command

root$ firewall-cmd --zone=public --add-port=80/tcp --permanent
root$ systemctl restart firewalld

After installation Apache directory

/ Etc / httpd / conf /: main configuration directory, Apache server configuration information are the main configuration file httpd.conf, including the port number, web hosting, the maximum number of connections, default access paths, and so on.

/etc/httpd/conf.d/: child configuration directory

/ Etc / httpd / log /: apache log logs if problems occur during use apache, error information can be found in the log file

/ Var / www / cgi-bin: cgi default directory publishing

/ Var / www / html: static pages default directory publishing

We create an index.html file in / var / www / html directory, simply set

root$ cd /var//www/html
root$ touch index.html
root$ echo "Hello World" > index.html

We can http: access //localhost/index.html: // localhost or http

2.PHP installation

//安装php
root$ yum install php -y
//安装mysql/mariadb依赖包
root$ yum install php-mysql -y

Let's verify PHP is installed correctly

root$ cd /usr/bin/
root$ echo '<?php echo "Hello PHP";echo "\n";?>' > hello.php
root$ php hello.php

See print out Hello PHP after the installation is successful

3.MariaDB installation

Before installing confirm whether installed on

root$ rpm -q mariadb
未安装软件包 mariadb

Mariadb install the client and server

root$ yum -y install mariadb mariadb-server

Set boot from the start, start mariadb service

root$ systemctl enable mariadb
root$ systemctl start mariadb

View Mariadb Launch OK

root$ ps -e | grep mysql

If you want to uninstall mariadb

root$ yum erase mariadb

4.Mariadb use

root$ mysql -u root -p

Mariadb is a branch of MySQL, the syntax is almost the same

5.phpMyAdmin installation (a MySQL database backend management tools)

root$ yum install phpMyAdmin -y

Be accessed through the website http: // localhost / phpMyAdmin

6.LAMP topology and the working process

LAMP topology Process Reference https://blog.csdn.net/sj349781478/article/details/84224440

    apache achieve the following main functions:

    First: http processing request to construct its own services and other response packet;

    Second: Apache configuration for PHP support response program (or a module by PHP FPM);

    Third: The method for configuring Apache php specific processing procedures, such as by a reverse proxy to php fcgi processing program.

    mariadb achieve the following main functions:

    First: PHP program providing storage of data;

    Second: PHP providing program reads the data (usually considered from the perspective of performance, try to read and write database separation).

    php achieve the following main functions:

    First: providing apache access interface, i.e., CGI or Fast CGI (FPM);

    Second: providing PHP interpreter for the program;

    Third: to provide basic environmental functions mairadb database connection.
