Summary of various methods for installing PHP extensions under CentOS system

Installing PHP Extensions

# wget Http://pecl.php.net/get/gearman-1.1.1.tgz
# tar ZXVF gearman-1.1.1.tgz
# CD gearman-1.1.1
#/usr/local/server/php/bin/phpize
#./configure--with-php-config=/usr/local/server/php/bin/php-config--with-gearman=/usr/local/server/ gearmand-1.1.7/
# Make && make install
The above steps will output the extended installation directory:/usr/local/server/php-5.4.14/lib/php/extensions/no-debug-non-zts-20100525/
To modify PHP.ini, add the following join statement:
Extension=/usr/local/server/php-5.4.14/lib/php/extensions/no-debug-non-zts-20100525/gearman.so

Reboot the PHP-FPM and use Phpinfo to see if the installation was successful
# Service PHP-FPM Restart

Note:

When you install the PHP extension, it is possible that the installation failed because of a version problem. So you'd better go to the official website to see the latest version

The general method of dynamically installing PHP extensions (figure)

First, explain the following Linux commands:

./configure #脚本配置工具

./configure--help #查看脚本配置工具configure的命令行选项

/usr/local/php/bin/phpize#phpsize command to extend a module in a compiled PHP

1. Download the package you want to install, extract the directory (such as: Phpredis)

2. Enter the package directory (CD Phpredis)

3. Execute phpsize command (phpize)

4. Configuration (./configure--with-php-config=/usr/local/php/bin/php-config #指定安装PHP时候的配置)

(Attached: The general method of specifying the location of the installation directory:--with-php-mysql=/usr/local/mysql# Specify the MySQL database location)

5. Compile installation (make && make install)

6. Successful compilation

At this point, the generated redis.so file is in this directory, and the local browser can also view the file:///usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/

7. Modify PHP configuration file (Vim/usr/local/php/etc/php.ini)

Add: extention = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/redis.so";

8. Reboot the server (/root/lnmp reload #重启nginx和PHP, according to your own environment)

Use Phpinfo () to view the PHP configuration list in the browser, OK, this installation is complete.
