Installation of LEMP (Linux, Nginx, MariaDB, and PHP) on CentOS
http://howvps.com/?p=386 In this article, I will instruct you how to install completely the whole well-known webserver LEMP including: Linux + Nginx + MariaDB + PHP (PHP-FPM) on CentOS 7/6.5/6.4/6.3/6.2/6.1/6/5.10. – Nginx (read as Engine x) is a small and compact webserver, uses less RAM, is strong and has high operating efficiency. – PHP supports the following versions: 5.3, 5.4, 5.5, 5.6. – MariaDB is the open-source version of MySQL, and operates completely like MySQL. From CentOS 7, it is default to support MariaDB, and you can use it instead of MySQL from now on.
I. Installation of Nginx and PHP on CentOS 7/6.5/5.10
Firstly, you need to prepare a brand new CentOS server without anything installed. Recheck hostname and file host for correct information before starting the installation. Use commands to install and also tool ZOC Terminal and nano.
Add necessary repositories
CentOS 7/6.5/5.10 Remi repository
## CentOS 7 ## rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm ## CentOS 6 ## rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm ## CentOS 5 ## rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
If you receive notice of error ‘File Not Found”, maybe the RPM version has changed. You can get the link of the newest version in wiki page Fedora EPEL CentOS 7/6.5/5.10 Nginx repository
## CentOS 7 ## rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm ## CentOS 6 ## rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm ## CentOS 5 ## rpm -Uvh http://nginx.org/packages/centos/5/noarch/RPMS/nginx-release-centos-5-0.el5.ngx.noarch.rpm
Install Nginx and PHP

Memcache (php-pecl-memcache)– Extension to work with the Memcached caching daemon
Memcached (php-pecl-memcached)– Extension to work with the Memcached caching daemon
GD (php-gd)– A module for PHP applications for using the gd graphics library
XML (php-xml)– A module for PHP applications which use XML
MBString (php-mbstring)– A module for PHP applications which need multi-byte string handling
MCrypt (php-mcrypt)– Standard PHP module provides mcrypt library support
To install, use the command
yum --enablerepo=remi,remi-php56 install module_name
. For example:
yum --enablerepo=remi,remi-php56 install -y php-opcache php-pecl-apcu php-cli php-pear php-pdo php-mysqlnd php-pgsql php-pecl-mongo php-pecl-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml
Stop httpd (Apache) server, Start Nginx và PHP-FPM
Stop httpd (Apache)
## CentOS 7 ## systemctl stop httpd.service ## CentOS 6.5/5.10 ## service httpd stop
Start Nginx
## CentOS 7 ## systemctl start nginx.service ## CentOS 6.5/5.10 ## service nginx start
Start PHP-FPM
## CentOS 7 ## systemctl start php-fpm.service ## CentOS 6.5/5.10 ## service php-fpm start
Autostart Nginx, PHP-FPM and disable httpd
Disable httpd (Apache) when booting
## CentOS 7 ## systemctl disable httpd.service ## CentOS 6.5/5.10 ## chkconfig httpd off
Autostart Nginx
## CentOS 7 ## systemctl enable nginx.service ## CentOS 6.5/5.10 ## chkconfig --add nginx chkconfig --levels 235 nginx on
Autostart PHP-FPM
## CentOS 7 ## systemctl enable php-fpm.service ## CentOS 6.5/5.10 ## chkconfig --add php-fpm chkconfig --levels 235 php-fpm on
Configure Nginx and PHP-FPM
Configure Nginx
– Change worker_processes nano /etc/nginx/nginx.conf
Adjust worker_processes using the processor number of your VPS – Configure nginx virtual hosts
nano /etc/nginx/conf.d/default.conf
You change information as follows:
# # The default server # server { listen 80; server_name example.com; location / { root /usr/share/nginx/html; index index.php index.html index.htm; try_files $uri $uri/ /index.php?q=$uri&$args; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ .php$ { root /usr/share/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
Those sections in red colour need to be adjusted. – Restart Nginx
## CentOS 7 ## systemctl restart nginx.service ## CentOS 6.5/5.10 ## service nginx restart
Configure PHP-FPM – Change user and group
nano /etc/php-fpm.d/www.conf
Change user and group = apache into 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 [...]
– Restart PHP-FPM
## CentOS 7 ## systemctl restart php-fpm.service ## CentOS 6.5/5.10 ## service php-fpm restart
Test configuration of Nginx and PHP-FPM
nano /usr/share/nginx/html/info.php
Add the following section:
Test with the link: http:///info.php. If you receive information on PHP, the installation is successfully done. Note: If you directly access into IP but receive notice of not being able to connect, open port http:
service iptables start iptables -I INPUT -p tcp --dport 80 -j ACCEPT service iptables save service iptables restart
II. Installation of MariaDB on CentOS 7/6.5/5.10
Add MariaDB repositories
Note: Do not need to implement on CentOS 7. The MariaDB version on CentOS 7 is currently 5.5.37
## CentOS 6/5 MariaDB 5.5 ## wget -O /etc/yum.repos.d/MariaDB.repo http://mariadb.if-not-true-then-false.com/centos/$(rpm -E %centos)/$(uname -i)/5 ## CentOS 6/5 MariaDB 10.0 ## wget -O /etc/yum.repos.d/MariaDB.repo http://mariadb.if-not-true-then-false.com/centos/$(rpm -E %centos)/$(uname -i)/10
Install or update MariaDB
## CentOS 7 ## yum install -y mariadb mariadb-server ## CentOS 6.5/5.10 ## yum install -y MariaDB MariaDB-server
Start MariaDB and autorun when booting
## CentOS 7 ## systemctl start mariadb.service systemctl enable mariadb.service ## CentOS 6.5/5.10 ## service mysql start chkconfig --levels 235 mysql on
Configure MariaDB
Set (Change) root password
Remove anonymous users
Disallow root login remotely
Remove test database and access to it
Reload privilege tables
– Start the installation
/usr/bin/mysql_secure_installation
Right at the first step, you will be asked for root password, because of new installation and not yet having a password, press ‘Enter’ to continue. – Output is as follows:
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. Set 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] y ... 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] y ... 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] y - Dropping test database... ... Success! - 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] y ... 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!
