Overview
The LNMP environment is a website server architecture consisting of Nginx, MySQL or MariaDB, and PHP running on Linux. This document describes how to manually set up the LNMP environment on a Tencent Cloud CVM.
To manually set up the LNMP environment, you should familiarize yourself with common Linux commands such as installing software via YUM in CentOS, and understand the usage and version compatibility of the software to be installed. Note:
It’s recommended that you can configure the LNMP environment through the image environment of Tencent Cloud marketplace, and it may take a long time to set up the LNMP environment manually.
Software
The following software is used to build the LNMP environment.
Linux: Linux operating system. This document uses CentOS 7.6 as an example.
Nginx: web server. This document uses Nginx 1.17.7 as an example.
MariaDB: database. This document uses MariaDB 10.4.8 as an example.
PHP: scripting language. This document uses PHP 7.2.22 as an example.
Prerequisite
Directions
Step 1: log in to a Linux instance
Step 2: install Nginx
1. Run the following command to create a file named nginx.repo
under /etc/yum.repos.d/
.
vi /etc/yum.repos.d/nginx.repo
2. Press i to switch to the editing mode and enter the following.
[nginx]
name = nginx repo
baseurl = https://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck = 0
enabled = 1
3. Click Esc and enter :wq to save and close the file.
4. Run the following command to install Nginx.
5. Run the following command to open the default.conf
file.
vim /etc/nginx/conf.d/default.conf
6. Press i to switch to the edit mode to modify the default.conf
file.
7. Find server{...}
and replace the content inside the curly brackets with the following. This is to cancel the listening of the IPv6 address and configure Nginx to realize linkage with PHP.
server {
listen 80;
root /usr/share/nginx/html;
server_name localhost;
location / {
index index.php index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
8. Press Esc and enter :wq to save and close the file.
9. Run the following command to start Nginx.
10. Run the following command to enable Nginx autostart.
11. Enter the following URL in your local browser and verify whether the Nginx service is working properly.
http://[Public IP address of the CVM instance]
If the following appears, Nginx has been successfully installed and configured.
Step 3: install a database
1. Run the following command to check if MariaDB is already installed.
rpm -qa | grep -i mariadb
If the following appears, MariaDB is already installed.
To avoid conflicts between different versions, run the following command to remove the installed MariaDB. yum -y remove [Package name]
If nothing is returned, MySQL has not been installed. In this case, proceed to the next step.
2. Execute the following command to create the MariaDB.repo
file under /etc/yum.repos.d/
.
vi /etc/yum.repos.d/MariaDB.repo
3. Press i to switch to edit mode and enter the following content to add MariaDB.
Note:
Different operating systems require different versions of MariaDB. Download MariaDB that is compatible with your operating system. If your CVM has private network access, change mirrors.cloud.tencent.com
to the private network address mirrors.tencentyun.com
. In this way, your public network traffic will not be affected and the access is faster.
[mariadb]
name = MariaDB
baseurl = https://mirrors.cloud.tencent.com/mariadb/yum/10.4/centos7-amd64
gpgkey=https://mirrors.cloud.tencent.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
4. Press Esc, enter :wq, save the file and return.
5. Run the following command to install MariaDB. Please pay attention to the installation progress and wait for the installation to complete.
yum -y install MariaDB-client MariaDB-server
6. Run the following command to start the MariaDB service.
7. Run the following command to enable MariaDB autostart.
8. Run the following command to verify that MariaDB is successfully installed.
If the following appears, MariaDB has been successfully installed.
9. Run the following command to exit MariaDB.
1. 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
2. Run the following command to install the packages required for PHP 7.2.
yum -y install mod_php72w.x86_64 php72w-cli.x86_64 php72w-common.x86_64 php72w-mysqlnd php72w-fpm.x86_64
3. Run the following command to start the PHP-FPM service.
4. Run the following command to enable PHP-FPM autostart.
Verifying the Environment Configuration
Follow these steps to verify that the LNMP environment has been built successfully.
1. Run the following command to create a test file.
echo "<?php phpinfo(); ?>" >> /usr/share/nginx/html/index.php
2. Run the following command to restart the Nginx service.
3. Enter the following URL in a local browser to check whether the environment configuration is successful.
http://[Public IP address of the CVM instance]
If the following appears, the environment has been successfully configured.
