RHEL 7 has been released and CentOS Linux 7 is on its way with many notable changes. This guide explains how to install LAMP server.
More about LAMP
LAMP is nothing but a software bundle or a platform consisting of Linux operating system, Apache web-server, MySQL database server and PHP (or Perl/Python)scripting language. The LAMP stack is used for building heavy-duty dynamic web sites entirely out of free and open-source software. In this tutorial, I’m going to explain how to Linux, Apache, MySQL/MariaDB (drop in replacement for MySQL), PHP (LAMP) stack On CentOS 7 or RHEL 7.
Assumptions
- I’m assuming that you’ve installed basic RHEL 7 or CentOS 7 server. Open the Terminal app and type the following command as root user.
- You must be familiar with the yum command
- You must know your Server’s IP address. Use the following command to find your server’s ip address for eth0 interface:
ifconfig eth0
OR
ip a show eth0
OR
ip addr list eth0 | awk '/inet /{sub(/\/[0-9]+/,"",$2); print $2}'
OR
ifconfig eth0 | awk '/inet /{print $2}'
10.41.143.156 - I’m going to use IP address 10.41.143.156 for testing purpose. Feel free to replace this IP address with your actual private or public IP address.
Enough talk, let’s set up LAMP stack.
Step #1: Install Apache on a CentOS 7 / RHEL 7 server
Type the following yum command to install Apache web-server:
sudo yum install httpd
Sample outputs:
Loaded plugins: amazon-id, rhui-lb Resolving Dependencies --> Running transaction check ---> Package httpd.x86_64 0:2.4.6-17.el7 will be installed --> Processing Dependency: httpd-tools = 2.4.6-17.el7 for package: httpd-2.4.6-17.el7.x86_64 --> Processing Dependency: /etc/mime.types for package: httpd-2.4.6-17.el7.x86_64 --> Running transaction check ---> Package httpd-tools.x86_64 0:2.4.6-17.el7 will be installed ---> Package mailcap.noarch 0:2.1.41-2.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ====================================================================================================== Package Arch Version Repository Size ====================================================================================================== Installing: httpd x86_64 2.4.6-17.el7 rhui-REGION-rhel-server-releases 1.2 M Installing for dependencies: httpd-tools x86_64 2.4.6-17.el7 rhui-REGION-rhel-server-releases 77 k mailcap noarch 2.1.41-2.el7 rhui-REGION-rhel-server-releases 31 k Transaction Summary ====================================================================================================== Install 1 Package (+2 Dependent packages) Total download size: 1.3 M Installed size: 3.9 M Is this ok [y/d/N]: y Downloading packages: (1/3): httpd-tools-2.4.6-17.el7.x86_64.rpm | 77 kB 00:00:00 (2/3): httpd-2.4.6-17.el7.x86_64.rpm | 1.2 MB 00:00:00 (3/3): mailcap-2.1.41-2.el7.noarch.rpm | 31 kB 00:00:00 ------------------------------------------------------------------------------------------------------ Total 2.0 MB/s | 1.3 MB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : httpd-tools-2.4.6-17.el7.x86_64 1/3 Installing : mailcap-2.1.41-2.el7.noarch 2/3 Installing : httpd-2.4.6-17.el7.x86_64 3/3 Verifying : mailcap-2.1.41-2.el7.noarch 1/3 Verifying : httpd-tools-2.4.6-17.el7.x86_64 2/3 Verifying : httpd-2.4.6-17.el7.x86_64 3/3 Installed: httpd.x86_64 0:2.4.6-17.el7 Dependency Installed: httpd-tools.x86_64 0:2.4.6-17.el7 mailcap.noarch 0:2.1.41-2.el7 Complete! |
Enable the httpd service at boot time
To make sure the httpd service start automatically at the boot time, enter:
sudo systemctl enable httpd.service
Sample outputs:
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
The following command will disable the httpd service at the boot time:
sudo systemctl disable httpd.service
Sample outputs:
rm '/etc/systemd/system/multi-user.target.wants/httpd.service'
Start the httpd service on a CentOS/RHEL v7.x
sudo systemctl start httpd.service
At this stage, you can point your web-browser to your server’s IP address such as http://10.41.143.156). The following page should display on screen:
Stop the httpd service on a CentOS/RHEL v7.x
sudo systemctl stop httpd.service
Restart the httpd service on a CentOS/RHEL v7.x
sudo systemctl restart httpd.service
Finding the httpd service status on a CentOS/RHEL v7.x
To verify that the httpd service is running, enter:
systemctl is-active httpd.service
Sample outputs:
active
Gracefully restart the httpd service on a CentOS/RHEL v7.x
sudo apachectl graceful
Test httpd/Apache configuration file for errors on a CentOS/RHEL v7.x
sudo apachectl configtest
Sample outputs:
Syntax OK
httpd service default configuration
- Default config file: /etc/httpd/conf/httpd.conf
- Configuration files which load modules : /etc/httpd/conf.modules.d/ directory (e.g. PHP)
- Select MPMs (Processing Model) as loadable modules [worker, prefork (default)] and event: /etc/httpd/conf.modules.d/00-mpm.conf
- Default ports: 80 and 443 (SSL)
- Default log files: /var/log/httpd/{access_log,error_log}
Step #2: Install MariaDB on a CentOS 7 / RHEL 7 server
MariaDB An enhanced, drop-in replacement for MySQL server. RHEL/CentOS v7.x shifts from MySQL to MariaDB for its database management system needs. Type the following yum command to install MariaDB server:
sudo yum install mariadb-server mariadb
To start mariadb, type:
sudo systemctl start mariadb.service
To make sure the mariadb service start automatically at the boot time, enter:
sudo systemctl enable mariadb.service
Sample outputs:
ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'
To stop/restart and disable mariadb service use the following commands:
sudo systemctl stop mariadb.service #<-- Stop mariadb server sudo systemctl restart mariadb.service #<-- Restart mariadb server sudo systemctl disable mariadb.service #<-- Disable mariadb server sudo systemctl is-active mariadb.service #<-- Is mariadb server running? |
Securing MariaDB
Type the following command:
sudo /usr/bin/mysql_secure_installation
Sample outputs:
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): PRESS-ENTER-KEY 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: YOUR-NEW-PASSWORD-HERE Re-enter new password: YOUR-NEW-PASSWORD-HERE 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!
Test MariaDB installation
Type the following command
mysql -u root -p
Sample outputs:
Step #3: Install PHP on a CentOS/RHEL v7.x
To install PHP and modules such as gd/msyql type the following yum command:
sudo yum install php php-mysql php-gd php-pear
You must restart the httpd (Apache) service, enter:
sudo systemctl restart httpd.service
To search all other php modules, type:
sudo yum search php-
Sample outputs:
php-cli.x86_64 : Command-line interface for PHP php-common.x86_64 : Common files for PHP php-gd.x86_64 : A module for PHP applications for using the gd graphics library php-ldap.x86_64 : A module for PHP applications that use LDAP php-mysql.x86_64 : A module for PHP applications that use MySQL databases php-odbc.x86_64 : A module for PHP applications that use ODBC databases php-pdo.x86_64 : A database access abstraction module for PHP applications php-pear.noarch : PHP Extension and Application Repository framework php-pecl-memcache.x86_64 : Extension to work with the Memcached caching daemon php-pgsql.x86_64 : A PostgreSQL database module for PHP php-process.x86_64 : Modules for PHP script using system process interfaces php-recode.x86_64 : A module for PHP applications for using the recode library php-soap.x86_64 : A module for PHP applications that use the SOAP protocol php-xml.x86_64 : A module for PHP applications which use XML php-xmlrpc.x86_64 : A module for PHP applications which use the XML-RPC protocol
To find more info about a module type:
sudo yum info php-pgsql
To install php module called php-pgsql type:
sudo yum install php-pgsql
Test PHP on your server
Create a file called /var/www/html/test.php as follows:
sudo vi /var/www/html/test.php
Append the following code:
<?php phpinfo(INFO_GENERAL); ?> |
Save and close the file. Point your web-browser to your server’s IP address such as http://10.41.143.156/test.php (feel free to replace the 10.41.143.156 with your actual IP address):
http://10.41.143.156/test.php
Sample outputs:
In next part, I will cover the following topics (rss feed for RHEL7 or rss for CentOS7 tutorials):
- Apache configuration
- Virtual hosting
- Apache security
- mod_ssl
- Perl
- Firewall configuration
Nice tutorial thanks!
Under “Test PHP on your server” there is an inconsistency between file names. test.php and info.php
Thanks for the heads up!
Hi Craig
I am trying to test php on my server.
I am able to get to the server but not to http:///test.php.
you should restart the apache service… `systemctl restart httpd`
Excellent Tutorial, just booted up a RHEL 7 instance on AWS, for testing and wasn’t sure about the steps. Looking forward for the next part.
Thanks for sharing!
Hi,
thank’s for the great tutorial. Do you have an idea why I do not have the service. I got the error that there is no service with this name. I tried it under CentOS 7
Kind regards
Robin
Here are a few notes I made after going through this guide on things you may want to do afterwords. If you’re curious about what some of it does please look it up, especially disabling SELinux and FirewallD (should only be done if non production environments):
Update CentOS:
yum update
Enable Apache and MySQL on boot:
systemctl enable httpd.service
systemctl enable mariadb.service
Disable SELinux:
setenforce 0
nano /etc/selinux/config
Secure MySQL:
mysql_secure_installation
Login to MySQL:
mysql -u root -p
Create MySQL User:
CREATE USER username
–> IDENTIFIED BY ‘password’;
Create MySQL Database:
CREATE DATABASE databasename;
Add User to Database:
grant all privileges on mydb.* to myuser@’%’ identified by ‘mypasswd’;
grant all privileges on mydb.* to myuser@localhost identified by ‘mypasswd’;
Disable FirewallD:
systemctl disable firewalld
systemctl stop firewalld
Restart MySQL & Apache
systemctl restart httpd.service
systemctl restart mariadb.service
Check Release Information:
cat /etc/*release
Thanks for the tips. I was having a hell of a time with the new CentOS 7 and any kind of apache OR nginx for a testing setup.
Your advice about firewalld exactly did the trick. Now I’ll read up on firewalld, and figure out that beast now!
Disabling firewalld or selinux should not be done in either production or development as first it suggests bad habits and second it is just not a good practice. If you cannot get it working in development then you should not be pushing it to production.
firewalld if you have not figured it out yet is going to be pretty straight forward. firewall-cmd –permanent –add-service=http; firewall-cmd –add-service=http is the most straightforward way to add access to web server.
[root@server ~]# firewall-cmd –get-services
amanda-client bacula bacula-client dhcp dhcpv6 dhcpv6-client dns ftp high-availability http https imaps ipp ipp-client ipsec kerberos kpasswd ldap ldaps libvirt libvirt-tls mdns mountd ms-wbt mysql nfs ntp openvpn pmcd pmproxy pmwebapi pmwebapis pop3s postgresql proxy-dhcp radius rpc-bind samba samba-client smtp ssh telnet tftp tftp-client transmission-client vnc-server wbem-https
[root@server ~]#
firewalld is dynamic so you will either need to add both the rule using –permanent and without –permanent or after using –permanent only run firewall-cmd –reload
You can use mysql for mariadb and https to ensure you have connectivity via port 443. Another thing to check is if the bind-address setting is right for mariadb. Setting it to 0.0.0.0 is generally the best setting unless you are only doing localhost connectivity. I believe leaving it unset is equivalent to 0.0.0.0 however in my experience there are issues with leaving it unset and remote connectivity.
If possible, please also suggest way to implement LEMP (Centos, Nignx, MariaDB, PHP)
Please help us how to install php-mssql extension on Centos7…
We have Apache and PHP and they work fine, just php_mssql we don’t have and don’t know how to install :(
Brilliant, Murdok. Disable the security systems to install a web server. Read a book before blindly posting such bad advise. If you can’t get a web server running with SELinux or FirewallD then perhaps Windows is for you.
RapidDave: Not sure why you’re being a hateful asshole but I did note not to do it on a production server and to read up on it. I didn’t want to write a book on using SELinux just in case someone only wanted a simple localhost server for practice . Again avoid disabling it on production servers. I’ll avoid trying to help in comments from now on since my notes were met with unwarranted hostility.
RapidDave, since when is Windows a secure enviroment out of the box?. Get yourself a book before posting such answers.
Thanks for the laugh tough, windows secure and out of the box!.
great tutorial
Very good tutorial.
I set up a new server with success on Apache and MySql but I cannot overcome problem with the Php installation. I have CentOS 7 operating system and when I try “sudo yum install php php-mysql php-gd php-pear” after:

Sorry about the long message, but do you have a reccommendation?
Excellent tutorial. Very helpful for a newbie Linux person.
Thank you!
I have installed phpMyAdmin on Apache 2.4 with Centos 7. But it seems slow to be opened. What should I look into in order to make it faster to access
Hello!
Where is the file mpm Envent to configure ?
Thanks
Thanks for the tutorial. It was very helpful.
Thanks!!
Great article, thank you.
this howto is worth shit-on-head. Really works for You, author? generally is it all about yum-install-something, but missing most important and heavy duty part – configuring all 3 types of apps work together. how apache knows to proxy .php requests to zend machine? where are –with-mysql toggles of php config required mysql sockets?
It did not work for me and broke my apache I had to reisntall againg
Thanks .. :)
Dear VIVEK GITE,
Nice tutorial, Thank you so much
Hi,
I have installed Apache mysql and PHP as per your suggestion and it was installed correctly .
so my server configuration is
apache 2.4
pap 5.4 and
mariadb 5.5
but the problem is my mb_String() stopped working
so I uninstall php only and tried to install php with mbstring but didn’t get success
So When I tried to install PHP as per above steps it was giving error
“Error: Package: php54-php-common-5.4.44-1.el6.remi.x86_64 (remi)
Requires: libgmp.so.3()(64bit)
You could try using –skip-broken to work around the problem
You could try running: rpm -Va –nofiles –nodigest”
can you suggest please
Gracias, me soluciono vario inconvenientes
Excellent Tutorial
Thanks for sharing.
Any tips/help on getting this setup with DB2? Seems like a rats nest of old/bad documentation for this particular rdbms.
Hey, on my comment above; I was able to resolve the issue. Apparently SELinux was blocking HTTPD from seeing anything related to DB2. I essentially turned SEL to permissive to get this working. Thanks for the great guide!
Hello!
