第 2 步：驗證
驗證它是否已成功啟動。
鍵入命令ps -few | grep memcached ps -few | grep memcached 。
|
1 2 |
bash - 3.2 $ ps - few | grep memcached 110048994 88258 88202 0 12 : 31PM ttys000 0 : 00.00 grep memcached |
您將看到 memcached 進程作為結果的一部分。
默認情況下，Memcached 在port 11211上運行。
使用
brew是在 Mac OS X 上安裝 Memcached 的最安全和最簡單的方法。如果您沒有在本地安裝 brew，請遵循以下手動方法。
