PHP installation mcrypt extension under CentOS

(The following steps are my actual operation, may be different from your installation method, but I will try to exclude doubts)

Approximate step (1) Install MCrypt, (2) Install PHP extension to MCrypt, (3) Restart Apache

(1), confirm that your Linux is not installed MCrypt library, if installed, skip the installation steps

[email protected] ~]# Yum list installed|grep mcryptlibmcrypt.x86_64                          2.5.8-4.el5.centos           installedlibmcrypt-devel.x86_64                    2.5.8-4.el5.centos           installedmcrypt.x86_64                             2.6.8-1.el5                  Installed

The above display has been installed, if not, the following two ways to install

(method i) Yum commands lazy people to install

Yum install Libmcrypt libmcrypt-devel mcrypt Mhash

After execution, you will be presented with a library of upcoming installations, which you can x86_64 or i386, such as Yum install libmcrypt.x86_64 (if the Yum command cannot connect to the repository, check your/etc/yum.repos.d/ The file is correct, and your/etc/host is not up to the domain name inside)

(method II) Source code compilation installation, go to http://www.sourceforge.net download Libmcrypt,mhash,mcrypt installation package
Libmcrypt (libmcrypt-2.5.8.tar.gz):
MCrypt (mcrypt-2.6.8.tar.gz):
Mhash (mhash-0.9.9.9.tar.gz):
2. Install Libmcrypt First

3. Installing Mhash

#tar-ZXVF mhash-0.9.9.9.tar.gz#cd Mhash-0.9.9.9#./configure#make#make Install

4. Installing MCrypt

#tar-zxvf mcrypt-2.6.8.tar.gz#cd mcrypt-2.6.8#ld_library_path=/usr/local/lib./configure#make#make Install

Finally, check whether the installation is successful

(2), install PHP mcrypt extension (dynamic load compilation)

Download the mcrypt extension under PHP or download the full installation package for PHP directly

http://cn.php.net/releases/Web page to find the PHP version of their own server, download tar decompression (my is php5.3.3)

Go to Ext/mcrypt folder

[Email protected]*_* 14:45 ~]# CD php-5.3.3/ext/mcrypt/

Execute the phpize command (Phpize is used to extend the PHP extension module, through the phpize can build PHP plug-in module, if not? Yum Install Php53-devel contains, or other methods)

[Email protected]*_* 14:48 mcrypt]# whereis phpize    //In order to determine phpize presence Phpize:/usr/bin/phpize/usr/share/man/man1/ Phpize.1.gz[[email protected]*_* 14:48 mcrypt]# phpizeconfiguring for:php API Version:         20090626Zend Module API no:< C4/>20090626zend Extension Api No:   220090626

After execution, you will find that the current directory is more than a few configure files, the final execution of the Php-config command is basically completed

Execute the following command to ensure that your/usr/bin/php-config is present

[Email protected]*_* 15:02 mcrypt]# whereis php-configphp-config:/usr/bin/php-config/usr/share/man/man1/ Php-config.1.gz[[email protected]*_* 15:02 mcrypt]#./configure--with-php-config=/usr/bin/php-config

If you encounter any of the following errors, install GCC First, command yum to install GCC

Configure:error:no acceptable C compiler found in $PATH

Until you do not error, appear: Config.status:creating config.h, execute the following command

[[Email protected]*_* 15:06 mcrypt]# make && make install

At the end of the final, you will be prompted as follows, stating that you are done

Installing shared extensions:     /usr/lib64/php/modules/

By the way, check if the mrcypt.so extension in/usr/lib64/php/modules/has been created successfully.

Then the thing is simple, add a extension=mcrypt.so to your php.ini

[Email protected]*_* 15:09 mcrypt]# CD/ETC/PHP.D

Create a Mrcypt.ini file on the line, inside write extension=mcrypt.so

[Email protected]*_* 15:17 php.d]# echo ' extension=mcrypt.so ' > Mcrypt.ini

(3), restart Apache, check the Phpinfo,mcrypt module extension is not loaded?
