LAMP server on centos 7<\/strong><\/p>\n

LAMP is a group of open source softwares installed together to build a webserver. LAMP refers to Linux (Operating system), Apache (Web service), MySQL\/MariaDB (Database) , PHP (Programming language).
\nThis guide helps you to install LAMP server on centos 7.
\nBefore starting installation, you need to setup Static IP and hostname .
\nYou can also refer this guide – Setup network on centos 7 to setup static ip and hostname.
\nInstall LAMP server on centos 7.
\n1. Apache installation.
\n2. Mysql installation.
\n3. PHP installation.
\n4. Testing all together.

Apache installation
\nStep 1 \u00bb Update the repositories.
\n[root@clusterserver1 ~]# yum check-update<\/p>\n

[root@clusterserver1 ~]# yum update<\/p>\n

[root@clusterserver1 ~]# yum install httpd
\nLoaded plugins: fastestmirror
\nLoading mirror speeds from cached hostfile
\n* base: mirror.vodien.com
\n* epel: mirrors.vinahost.vn
\n* extras: mirror.vodien.com
\n* updates: mirror.vodien.com
\nPackage httpd-2.4.6-31.el7.centos.x86_64 already installed and latest version
\nNothing to do
\n[root@clusterserver1 ~]#<\/p>\n

Apache installation
\nStep 1 \u00bb Update the repositories.<\/p>\n

[root@clusterserver1 ~]# systemctl start httpd.service
\n[root@clusterserver1 ~]# systemctl star^Chttpd.service
\n[root@clusterserver1 ~]# systemctl enable httpd.service
\n[root@clusterserver1 ~]# systemctl status httpd.service
\nhttpd.service – The Apache HTTP Server
\nLoaded: loaded (\/usr\/lib\/systemd\/system\/httpd.service; enabled)

\nApr 12 03:30:50 clusterserver1 systemd[1]: Started The Apache HTTP Server.
\nApr 12 03:37:16 clusterserver1 systemd[1]: Started The Apache HTTP Server.
\nHint: Some lines were ellipsized, use -l to show in full.<\/p>\n

By default, Apache will listen on port 80. you need to exclude from firewall.
\nyou can simply exclude http service from firewall.<\/p>\n

firewall-cmd –permanent –add-service http
\nor you can exclude using port number. Below command will be useful for ports other than 80<\/p>\n

firewall-cmd –permanent –add-port=8080\/tcp<\/p>\n

Step 5 \u00bb Now restart firewall service.
\nsystemctl restart firewalld.service<\/p>\n

\"apache\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

MySQL installation.<\/p>\n

Start installing MariaDB, MySQL drop-in replacement.
\n[root@clusterserver1 ~]# yum install mariadb-server mariadb
\n[root@clusterserver1 ~]# systemctl start mariadb
\n[root@clusterserver1 ~]#
\n[root@clusterserver1 ~]# mysql_secure_installation
\n\/usr\/bin\/mysql_secure_installation: line 379: find_mysql_client: command not found<\/p>\n

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
\nSERVERS IN PRODUCTION USE!\u00a0 PLEASE READ EACH STEP CAREFULLY!<\/p>\n

In order to log into MariaDB to secure it, we’ll need the current
\npassword for the root user.\u00a0 If you’ve just installed MariaDB, and
\nyou haven’t set the root password yet, the password will be blank,
\nso you should just press enter here.<\/p>\n

Enter current password for root (enter for none):
\nERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)
\nEnter current password for root (enter for none):
\nOK, successfully used password, moving on…<\/p>\n

Setting the root password ensures that nobody can log into the MariaDB
\nroot user without the proper authorisation.<\/p>\n

Set root password? [Y\/n] Y
\nNew password:
\nRe-enter new password:
\nPassword updated successfully!
\nReloading privilege tables..
\n… Success!<\/p>\n

By default, a MariaDB installation has an anonymous user, allowing anyone
\nto log into MariaDB without having to have a user account created for
\nthem.\u00a0 This is intended only for testing, and to make the installation
\ngo a bit smoother.\u00a0 You should remove them before moving into a
\nproduction environment.<\/p>\n

Remove anonymous users? [Y\/n] Y
\n… Success!<\/p>\n

Normally, root should only be allowed to connect from ‘localhost’.\u00a0 This
\nensures that someone cannot guess at the root password from the network.<\/p>\n

Disallow root login remotely? [Y\/n] n
\n… skipping.<\/p>\n

By default, MariaDB comes with a database named ‘test’ that anyone can
\naccess.\u00a0 This is also intended only for testing, and should be removed
\nbefore moving into a production environment.<\/p>\n

Remove test database and access to it? [Y\/n] Y
\n– Dropping test database…
\n… Success!
\n– Removing privileges on test database…
\n… Success!<\/p>\n

Reloading the privilege tables will ensure that all changes made so far
\nwill take effect immediately.<\/p>\n

Reload privilege tables now? [Y\/n] y
\n… Success!<\/p>\n

Cleaning up…<\/p>\n

All done!\u00a0 If you’ve completed all of the above steps, your MariaDB
\ninstallation should now be secure.<\/p>\n

Thanks for using MariaDB!<\/p>\n

PHP installation.
\nInstall PHP and other recommended packages.
\nyum install php php-mysql<\/p>\n

Additional packages are required if you would like to install phpmyadmin .<\/p>\n

yum install php-gd php-pear php-mbstring php-pgsql<\/p>\n

Now restart apache service<\/p>\n

systemctl restart httpd.service<\/p>\n

 <\/p>\n

[root@clusterserver1 html]# cat phpinfo.php
\n<?php phpinfo(); ?><\/p>\n

\"apache2\"<\/a><\/p>\n

[root@clusterserver1 html]# cat dbtest.php
\n<?php
\n$con = mysql_connect(“localhost”,”root”,”test123″);
\nif (!$con)
\n{
\ndie(‘Could not connect: ‘ . mysql_error());
\n}
\nelse
\n{
\necho “Congrats! connection established successfully”;
\n}
\nmysql_close($con);
