Building swoole from sources

You are recommended to download the latest stable version of swoole. You can download the source code from one of the following the links.

Steps of Compilation

The process of compile and install the swoole extension for PHP

cd swoole          #  enter the directory of swoole source code   
phpize             #  prepare the build environment for a PHP extension
./configure        #  add configuration paramaters as needed
make               #  a successful result of make is swoole/module/swoole.so
sudo make install  #  install the swoole into the PHP extensions directory

Enable swoole

After installing the swoole extension to the PHP extensions directory, you will need to edit php.ini and add an extension=swoole.so line before you can use the swoole extension.

php -i | grep php.ini                      # check the php.ini file location
sudo echo "extension=swoole.so" >> php.ini  # add the extension=swoole.so to the end of php.ini
php -m | grep swoole                       # check if the swoole extension has been enabled
