(learning video recommendation: linux video tutorial)

Specific steps:

//Download files
 #wget http://pecl.php.net/get/zip-1.12.4.tgz
 //unzip files
 #tar zxfv zip-1.12.4.tgz
 //Enter the decompressed file directory
 #cd zip-1.12.4
 //Check the system configuration and start configuration, specify the configuration when installing PHP
 #./configure --with-php-cOnfig=/usr/local/php-5.2.17/bin/php-config
 //compile
 #make
 //test
 #make test
 //Install
 #make install

Method 2: pecl installation

Concrete steps:

1. First check whether there is pecl under /usr/local/php/bin/ , pear (php-pear is installed to use phpize in pecl) if not, install with yum

yum install php-pear,php-devel

2. Update the pecl library

pecl channel-update pecl.php.net

3. Install the corresponding Extension

pecl install redis

If you do not add the path of php to the environment variable, you need to use the absolute address

4. Generally, extensions installed through pecl are automatically added to the configuration of php.ini. If no extensions are found through phpinfo() or php-m, add the corresponding so file to php.ini (extension=redis.so) and then restart php-fpm
