CENTOS6 system installation Configuration Lamp Server (APACHE+PHP5+MYSQL)

Prepare the article:

1, configure the firewall, open 80 ports, 3306 ports
Vi/etc/sysconfig/iptables
-A input-m state--state new-m tcp-p TCP--dport 80-j ACCEPT #允许80端口通过防火墙
-A input-m state--state new-m tcp-p TCP--dport 3306-j ACCEPT #允许3306端口通过防火墙

Note: Many netizens have added these two rules to the last line of the firewall configuration, causing the firewall to start failing,

The correct one should be added to the default 22 port under this rule

As shown below:

Enter the server IP address in the client browser and see the relevant configuration information as shown in the following figure!

NOTE: The Apache default program directory is/var/www/html

Permission settings: Chown apache.apache-r/var/www/html

And then we're going to install the phpMyAdmin, it's just the environment is configured.

installs phpMyAdmin rpm–import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
Yum install http:// PKGS.REPOFORGE.ORG/RPMFORGE-RELEASE/RPMFORGE-RELEASE-0.5.2-2.EL6.RF.I686.RPM (i386)
Yum install phpMyAdmin vim/ Usr/share/phpmyadmin/config.inc.php
The inside of the $cfg[' blowfish_secret '] = ';    single quotation mark inside write the number of random (empty will error)
The configuration file now requires a top secret phrase password (blowfish_secret)
$cfg [' blowfish_secret '] = ' admin ';
Access localhost/phpmyadmin  How to show the prompts " Don ' t have permission to access/phpmyadmin/on this server. "
Change/etc/httpd/conf.d/phpmyadmin.conf inside
to convert Allow from 127.0.0.1 to Allow from  all.
this time when accessing phpMyAdmin in the address bar is still inaccessible
phpMyAdmin this folder to the Apache working directory, the default APAHCE working directory is in/var/www/html, Here I changed the default working environment for it.
Vi/etc/httpd/conf/httpd.conf
Changes the inside DocumentRoot "/var/www/html" to DocumentRoot "/var/www"
So my phpmyadmin is copied directly to the/var/www
