Setting up LAMP manually

Last updated: 2020-03-06 11:10:10

Scenario

LAMP is a common web service architecture run on Linux and consisting of Apache, MySQL/MariaDB, and PHP. This article describes how to set up LAMP on a Linux CVM.

You should be familiar with common Linux commands, such as Installing Software via YUM in a CentOS Environment, and understand the versions of the installed software.

Software

These are the software involved:

CentOS is a distribution of the Linux operating system. We will use version 7.6 in this article.
Apache is a web server software. We will use version 2.4.6 in this article.
MariaDB is a database management system. We will use version 10.4.8 in this article.
PHP is a scripting language. We will use version 7.0.33 in this article.

Prerequisites

You need a Linux CVM. If you have not purchased one yet, see Getting Started with Linux CVMs.

Instructions

Step 1: Logging in to a Linux instance

Log in to a Linux instance using WebShell (recommended). You can also use other login methods that you are comfortable with:

Step 2: Installing Apache

Run the following command to install Apache.
```
yum install httpd -y
```
Run the following commands to start Apache and set it to start automatically when the system starts.
```
systemctl start httpd
```
```
systemctl enable httpd
```
Open a browser window and visit the following URL to verify that Apache is working properly.
```
http://[Public IP address of the CVM instance]
```
The following appears if Apache is installed properly:

Step 3: Installing MariaDB

Run the following command to check if MariaDB is already installed.
```
rpm -qa | grep -i mariadb
```
- If the following appears, MariaDB is already installed.
  
  If that’s the case, run the following to remove MariaDB to avoid conflicts between different versions.
```
yum -y remove [Package name]
```
- If nothing is returned, MariaDB is not installed. In this case, proceed to the next step.
Run the following command to create a file named MariaDB.repo under /etc/yum.repos.d/.
```
vi /etc/yum.repos.d/MariaDB.repo
```

Press i to switch to edit mode and input the following.

# MariaDB 10.4 CentOS repository list - created 2019-11-05 11:56 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

For installation information for other versions, visit the MariaDB official website.

Press Esc and input :wq to save the file and go back.

Run the following command to install MariaDB.

yum -y install MariaDB-client MariaDB-server

Run the following commands to start MariaDB and set it to start automatically when the system starts.
```
systemctl start mariadb
```
```
systemctl enable mariadb
```
Run the following command to verify that MariaDB is successfully installed.
```
mysql
```
If the following appears, MariaDB is successfully installed.
Run the following command to exit MariaDB.
```
\q
```

Step 4: Installing and configuring PHP

Run the following commands to update the software source of PHP in Yum.

rpm -Uvh https://mirrors.cloud.tencent.com/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Run the following command to install the packages required for PHP 7.0.33.

yum -y install php70w php70w-opcache php70w-mbstring php70w-gd php70w-xml php70w-pear php70w-fpm php70w-mysql php70w-pdo

Run the following command to edit the Apache configuration file.
```
vi /etc/httpd/conf/httpd.conf
```
Press i to enter edit mode and make the following changes:
1. Find ServerName www.example.com:80 and start a new line below it. Input the following:
```
ServerName localhost:80
```
2. Find Require all denied in <Directory> and change it to Require all granted.
3. Find <IfModule dir_module> and change the content to DirectoryIndex index.php index.html.
4. Start a new line below AddType application/x-gzip .gz .tgz and input the following:
```
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
```
Press Esc and input :wq to save the file and go back.
Run the following command to restart Apache.
```
systemctl restart httpd
```

Verifying the Environment Configuration

Run the following command to create a test file.

echo "<?php phpinfo(); ?>" >> /var/www/html/index.php

Open a browser window on your local machine and visit the following URL to check whether the environment configuration is successful.
```
http://CVM Public IP/index.php
```
If the following appears, the LAMP environment is configured successfully.
