CentOS 6.2 uses yum to install LAMP and phpMyadmin

#If The requested URL returned error: 404 is prompted, please change to the latest version
rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2 .el6.rf.i686.rpm
rpm -ivh http://download.Fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm

Steps 2. Install php/mysql/httpd

#Install apache
yum -y install httpd httpd-devel
#Install mysql
yum -y install mysql mysql-devel mysql-server mysql-libs
#Install php
yum -y install php
#Install php extensions
yum -y install php-mysql php-gd php-imap php-ldap php-odbc php-mbstring php-devel php-soap php-cli php-pdo
yum -y install php-mcrypt php-tidy php- xml php-xmlrpc php-pear
#Other uncommon php extensions, www.linuxidc.com do not need to be installed
yum -y install php-pecl-memcache php-eaccelerator
#Install phpmyadmin
yum -y install phpmyadmin
#Installation completed After that, start
service httpd start
service mysqld start

Step 3. Configure httpd and mysqld to start automatically at boot

chkconfig mysqld on
chkconfig httpd on

Step 4. Configure phpmyadmin Modify /usr/share/phpmyadmin/config.inc.php

# Modify the abcde text here to your own characters, you can arbitrarily
$cfg['blowfish_secret'] = 'abcde';

The following introduces the problems encountered in the yum installation lamp environment common problem.

1. phpmyadmin prompts that php-mcrypt is not enabled. This is because the php-mrcrpt extension is not installed. There is no php-mrcrpt extension in the official source. Please install the epel source and then yum install php-mcrypt.

2, phpmyadmin cannot be accessed By default, phpmyadmin can only be accessed using http://localhost/phpmyadmin. You can modify the corresponding part in /etc/httpd/conf.d/phpmyadmin.conf as

 Order Deny,Allow
# Deny from all
 Allow from All

Highly not recommended By doing this, it is unsafe to expose phpmyadmin.

Note: Apache parses php, modifies the httpd.conf file, and adds

Addtype application/x-httpd-php .php .phtml
Addtype application/x-httpd-php-source .phps

myql can log in remotely and set mysql password:

mysql>; USE mysql;
mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
mysql>; FLUSH PRIVILEGES;

1.2 .3 Allow remote login

mysql -u root -p
Enter Password:
mysql>GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

After completion, you can use mysql-front to remotely manage the mysql database.

Set mysql to start at boot:

chkconfig mysqld on
