Install LEMP Server On Fedora 19

LEMP is a combination of the operating system and open-source software stack. The acronym LEMP is derived from first letters of Linux, Nginx HTTP Server, MySQL database, and PHP, Perl or Python. We already have shown you how to install LAMP on many platforms.

Install Nginx

Nginx (pronounced engine-x) is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server written by Igor Sysoev.

First login as root user to perform installation:

$ su

To install Nginx enter the following command in your terminal:

# yum install nginx -y

Enable Nginx service to start automatically on every reboot:

# systemctl enable nginx.service

Start Nginx service using the command:

# systemctl start nginx.service

Test nginx

Open up your web browser and navigate to http://ip-address/ or http://localhost/. You will see a screen something like below.

Configure Nginx

Open the file /etc/nginx/nginx.conf in any editor:

# vi /etc/nginx/nginx.conf 

Set the worker_processes (i.e No. of CPU’s in your system). To see the no. of CPU’s, use the command “lscpu”. In my case it’s “1″. So I set this as ’1′:

worker_processes 1;

Scroll down further in this configuration file and set the server name and PHP scripts:

#
# The default server
#
server {
    listen       80;
    server_name  fedora.unixmen.com;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

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

    error_page  404              /404.html;
    location = /404.html {
        root   /usr/share/nginx/html;
    }

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    ## Uncomment or Add the following lines
    location ~ \.php$ {
             root           /usr/share/nginx/html;
             try_files $uri =404;
             fastcgi_split_path_info ^(.+\.php)(/.+)$;
             fastcgi_pass   127.0.0.1:9000;
             fastcgi_index  index.php;
             fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
             include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

Save and close the file. Restart Nginx service:

# systemctl restart nginx.service

Install MariaDB

MariaDB is a drop in replacement for MySQL. It is a robust, scalable and reliable SQL server that comes rich set of enhancements. The default database of Fedora 19 is MariaDB.

Install it using the following command:

# yum install mysql mysql-server -y

Enable MySQL service at boot time with following command:

# systemctl enable mysqld.service

And start MySQL service using command:

# systemctl start mysqld.service

Set MySQL root password

By default MySQL root password is empty. So to prevent unauthorized access to MySQL, let us set root user password:

# mysql_secure_installation 

/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS 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 current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] 
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] 
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] 
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] 
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Install PHP

PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely used open-source general purpose scripting language that is especially suited for web development and can be embedded into HTML.

Install PHP with following command:

# yum install php-fpm php-mysql php-common -y

Enable and start php-fpm service:

# systemctl enable php-fpm.service
# systemctl start php-fpm.service

Configure PHP

Open up /etc/php.ini file in any editor:

# vi /etc/php.ini

Find the line cgi.fix_pathinfo and change the value from 1 to 0 (zero):

[...]
; http://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo
cgi.fix_pathinfo=0
[...]

Open up the file /etc/php-fpm.d/www.conf:

# vi /etc/php-fpm.d/www.conf 

And change the user and group values from apache to nginx:

[...]
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
[...]

Save and close the file. Restart php-fpm service:

# systemctl restart php-fpm.service

Test PHP

Create a sample “testphp.php” file in Apache document root folder:

# vi /usr/share/nginx/html/testphp.php

Append the lines as shown below:

<?php
phpinfo();
?>

Save and close the file. Restart Nginx service:

# systemctl restart nginx.service

Navigate to http://server-ip-address/testphp.php. It will display all the details about PHP such as version, build date and commands etc.

That’s it. LEMP server has been installed and it is ready to host your website now.
