Open Swoole

Open Swoole is a programmatic server for PHP with async IO, coroutines and fibers: secure, reliable, high performance


Documentation for Open Swoole can be found on the Open Swoole website.


Open Swoole always provides the most reliable stability and the most powerful features in the latest released version. Please ensure as much as possible that you are using the latest version.

1. Install or upgrade Open Swoole from multiple distribution channels

Please check Open Swoole Installation Guide about how to install Open Swoole on Ubuntu/CentOS/Windows WSL from Docker, PECL or Binary releases channels.

2. Compile from source

Compiling requirements

  • Linux, OS X or Cygwin, WSL
  • PHP 7.2.0 or later (The higher the version, the better the performance.)
  • GCC 4.8 or later

Download the source packages from Releases or:

git clone && \
cd swoole-src
git checkout v4.9.1
phpize && \
./configure && \
make && make install

Compile configurations

for example: ./configure --enable-openssl --enable-sockets

  • --enable-openssl or --with-openssl-dir=DIR
  • --enable-sockets
  • --enable-http2
  • --enable-mysqlnd (need mysqlnd, it just for supporting $mysql->escape method)
  • --enable-swoole-json
  • --enable-swoole-curl
  • --with-postgres[=DIR]

Enable Open Swoole extension

After compiling and installing the openswoole extension, you have to add a new line at the end of php.ini or create a ini file at conf.d folder to enable Open Swoole. It is recommended to be added after all the other extensions because openswoole may depend on extensions: sockets, mysqlnd, curl etc.
