The memcache extension method for installing PHP is as follows (only a module is installed here)

Download and compile and install the

Here beta means the test version, stable is the stable version, according to Individuals need to choose, click the .tgz package under Downloads to download directly.

You can download the package and transfer it to the server, or you can use the wget command directly. The wget method I use here:

wget http://pecl.php.net/get/memcache-2.2.5.tgz
tar xzfv memcache-2.2 .5.tgz
cd memcache-2.2.5
/usr/local/php/bin/phpize
You can run it according to the location of your own phpize (if you don't know where phpize is, directly find / -name phpize to find it), after running, the following information will be prompted, and then you can compile it Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 Compile: ./configure
