Mac OS使用brew安装memcached

brew info memcached

memcached: stable 1.5.9 (bottled)
High performance, distributed memory object caching system
https://memcached.org/
Conflicts with:
  mysql-cluster (because both install `bin/memcached`)
/usr/local/Cellar/memcached/1.5.9 (11 files, 199.3KB) *

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/memcached.rb
==> Dependencies
Required: libevent ✔
==> Options
--with-sasl
    Enable SASL support -- disables ASCII protocol!
--with-sasl-pwdb
    Enable SASL with memcached's own plain text password db support -- disables ASCII protocol!
==> Caveats
To have launchd start memcached now and restart at login:
  brew services start memcached
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/memcached/bin/memcached

brew install libevent 

brew install memcached

brew services start memcached

ps -ef|grep memcached
