CentOS 6.5 System installation Configuration lamp (APACHE+PHP5+MYSQL) Server environment

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 add these two rules to the last line of the firewall configuration, causing the firewall to fail to start.

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

As shown below:

phpMyAdmin Frequently Asked Questions
1. The phpMyAdmin prompt does not turn on Php-mcrypt because the php-mrcrpt extension is not installed. There is no php-mrcrpt extension in official source, please install Epel source and then yum install Php-mcrypt

2. phpMyAdmin Cannot access

phpMyAdmin By default can only be accessed using http://localhost/phpmyadmin, you can modify the corresponding part of the/etc/httpd/conf.d/phpmyadmin.conf into
<directory "/usr/share/phpmyadmin" >
Order Deny,allow
# Deny from all
Allow from all
</Directory>
But it's strongly not supportive, exposing phpmyadmin to insecurity.

Attention:
Apache parses PHP, modifies httpd.conf files, adds
AddType application/x-httpd-php. php. phtml
AddType Application/x-httpd-php-source. Phps

MYQL can Telnet
Set MySQL password
mysql>; Use MySQL;
mysql>; UPDATE user SET Password=password (' newpassword ') WHERE user= ' root ';
mysql>; FLUSH privileges;
1.2.3 Allow remote logins
Mysql-u root-p
Enter Password: <your new password>
Mysql>grant all privileges on * * to ' user name ' @ '% ' identified by ' password ' with GRANT OPTION;
When you're done, you can manage MySQL remotely with Mysql-front.
Set to boot
Chkconfig mysqld on
