Method 2: pecl installation

Specific steps:

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

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 php path to the environment variable, you need to use the absolute address

4. Generally, extensions installed through pecl are automatically added to the php.ini configuration. If you use phpinfo() or If php-m does not query the installed extension, add the corresponding so file to php.ini (extension=redis.so) and restart php-fpm
