Using Yum to install lamp (linux+apache+mysql+php) and configuration under CentOS

First of all, my practice configuration, centos6.5 (64-bit), networking

Prepare before installation: Turn off Firewall service iptables stop

• Install MySQL

Open terminal, root user

1	yum install mysql mysql-server

Installation complete, set MySQL self-boot

12	chkconfig --levels 235 mysqld on/etc/init.d/mysqld start   //或者service mysqld start

Set the password for the MySQL root account (I did not create a new MySQL user, just use the root account), enter the following

1	mysql_secure_installation

When the following prompt appears

Enter Current Paaword for Root

Because our root password is empty, so go straight to the carriage

Then follow the prompts, enter a new password, confirm, there will be four confirmation, direct return to the line

• Installing Apache

1	yum install httpd

Configuring self-booting

1	chkconfig --levels 235 httpd on<br>service httpd start

The following error may occur at this point on startup

Starting httpd:httpd:could not reliably determine the server ' s fully qualif domain name,

Using::1 for ServerName

Workaround:

We want to modify the/etc/httpd/conf/httpd.conf file

Enter VI to modify the status to find #servername www.example.com:80

Cancel # and change to servername domain name: 80 (if no domain name, it is set to localhost)

wq! Save exit

1	service httpd start或restart

Restart httpd, you can now access your server, enter localhost, a test page for Apache test page powered by CentOS

• Install PHP

Same input command

1	yum install php

Install directly, we need to restart the HTTPD service once the installation is complete.

After restarting we test PHP related information, we create a new PHP interface to test

1	vi  /var/www/html/info.php<br>按  i   进行编辑，输入：<br><?php<br>phpinfo();<br>?>

Edit complete, save exit

At this time we visit this page, enter localhost/info.php, there will be a real PHP information page, stating that your PHP installation was successful

• Associating a PHP module with a MySQL module

In this step, we will install the relevant module

Search for modules first

1	yum search php（在网上看到的步骤，并不知道有什么卵用）

Then install the relevant module

1	yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml  php-xmlrpc

Online also has the following installation package, I chose the above, should be able to

12	yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt本篇文章来源于 Linux公社网站(www.linuxidc.com)  原文链接：http://www.linuxidc.com/Linux/2014-12/111030.htm

Installation complete, restart Mysqld, restart httpd

Once again to visit the info.php, we found that there is more information about MySQL (no stickers)
