Disable Homebrew Auto Update

Homebrew will do self update when we install a package. Sometimes this is not what we want. We are okay using an old version of Homebrew and some old packages.

To prevent Homebrew doing automatic update just set an environment variable named `HOMEBREW_NO_AUTO_UPDATE`.

$ HOMEBREW_NO_AUTO_UPDATE=1 brew install [PACKAGE]

Swoole is Production-Grade Async programming Framework for PHP. It helps you write high-performance asynchronous non-blocking I/O. Similar with Go or NodeJS.

$ export LD_LIBRARY_PATH=$( brew --prefix openssl )/lib
$ export CPATH=$( brew --prefix openssl)/include
$ export PKG_CONFIG_PATH=$( brew --prefix openssl )/lib/pkgconfig
