    LEMP installation on Arch Linux

It’s always a good idea to refresh repository and perform an update first.
Open terminal and execute:

sudo pacman -Syu
The Arch Linux repository contains two versions of

Nginx Web server: nginx and nginx-mainline.
nginx is the more stable and older version and
nginx-mainline is the latest version. You can install nginx
In this Gist, I’m going to explain how you can install nginx-mainline
sudo pacman -S nginx-mainline
After installed nginx, start & check nginx status:

sudo systemctl start nginx
sudo systemctl status nginx

If nginx is not running, start it:

sudo systemctl start nginx
Enable nginx to start at bootup

sudo systemctl enable nginx
Check nginx has started or not:

sudo systemctl status nginx
Test nginx service:

sudo nginx -t 
If you see a warn like that:

[warn] 15117#15117: could not build optimal
types_hash, you should increase either
types_hash_max_size: 1024 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
Open nginx configuration file and edit
sudo nano /etc/nginx/nginx.conf
Add these lines inside http block:
types_hash_max_size 4096;
server_names_hash_bucket_size 128;

Save and exit (CTRL+X, Y, Enter).
Reload and test nginx:
sudo systemctl reload nginx
sudo nginx -t

Check nginx version:

nginx -v
Install MariaDB/MySQL

sudo pacman -S mysql
You need to initialize the MariaDB data

directory prior to starting the service:
sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
Enable MariaDB service:

sudo systemctl enable mysqld
Start MariDB service:

sudo systemctl start mysqld
Check MariaDB service status:

sudo systemctl status mysqld
Run secure installation

and set root password:
sudo mysql_secure_installation
or (sudo /usr/bin/mysql_secure_installation)
Install PHP 7.2

sudo pacman -S php-fpm
After installed PHP, we need to edit

nginx configuration file:
sudo nano /etc/nginx/nginx.conf
Find block below and add index.php

location / { /root /usr/share/nginx/html;
 index index.html index.htm index.php;
}

Find PHP section in configuration file

and edit:
location ~ \.php$ {
            root           /usr/share/www;
            fastcgi_pass   unix:/run/php-fpm/php-fpm.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
}

Save and close nginx configuration file after you have edited (CTRL+X, Y, Enter)
Then start and enable php-fpm service:

sudo systemctl start php-fpm
sudo systemctl enable php-fpm

To test PHP configuration,

create a test.php file in nginx web directory:
sudo nano /usr/share/www/test.php
(If you don’t have www directory in share folder, first you need to create one: sudo mkdir /usr/share/www)
Reload nginx service:

sudo systemctl reload nginx
Test PHP, open your browser:

http://localhost/test.php  or
http://127.0.0.1/test.php 
You must see php version info page
Enable extensions, open php.ini file

sudo nano /etc/php/php.ini
Find these lines and remove semicolons:

;extension=bz2
;extension=curl
;extension=mysqli
;extension=pdo_dblib
;extension=pdo_mysql
;extension=pdo_odbc
;extension=pdo_pgsql
;extension=pdo_sqlite
;extension=zip

Save and close php.ini file
Reload php-fpm service for the changes

to take effect:
sudo systemctl reload php-fpm
Install phpMyAdmin (PMA)

sudo pacman -S phpmyadmin
Then, create a symbolic link for phpMyaAdmin

system path to Nginx default root path:
sudo ln -s /usr/share/webapps/phpMyAdmin/ /usr/share/www/
Finally restart nginx and php-fpm services:


sudo systemctl restart nginx
sudo systemctl restart php-fpm
