安裝redis
redis的安裝方法有2種：下載源碼編譯安裝和使用homebrew安裝。本文采用后一種方法，如需下載源碼編譯安裝參考 mac下安裝配置redis。通過homebrew安裝redis:
$ brew install redis
終端輸出
==> Downloading http://download.redis.io/releases/redis-3.2.3.tar.gz ######################################################################## 100.0% ==> make install PREFIX=/usr/local/Cellar/redis/3.2.3 CC=clang ==> Caveats To have launchd start redis now and restart at login: brew services start redis Or, if you don't want/need a background service you can just run: redis-server /usr/local/etc/redis.conf ==> Summary 🍺 /usr/local/Cellar/redis/3.2.3: 10 files, 1.7M, built in 21 seconds
從以上日志輸出可以看出，如果需要給redis服務端指定配置文件，啟動命令應該是這樣的:
$ redis-server /usr/local/etc/redis.conf
配置文件
安裝完成后redis默認的配置文件redis.conf位於
/usr/local/etc
同時，redis-sentinel.conf也在這里。
使用cat命令查看redis.conf：
$ cat /usr/local/etc/redis.conf
終端輸出文件內容（刪掉了大部分注釋）：

官網上對於如何配置redis的描述:
Redis is able to start without a configuration file using a built-in default configuration, however this setup is only recommended for testing and development purposes. The proper way to configure Redis is by providing a Redis configuration file, usually called redis.conf.
根據以上內容,如果啟動時不指定配置文件,redis會使用程序中內置的默認配置.但是只有在開發和測試階段才考慮使用內置的默認配置，正式環境最好還是提供配置文件，並且一般命名為redis.conf
啟動redis
可以通過以下命令啟動redis：
$ redis-server /usr/local/etc/redis.conf
終端輸出

可以看出redis服務器啟動成功，並在監聽6379端口的網絡連接。
注意: 使用命令$ redis-server也可以啟動,此時並不會加載任何配置文件,使用的是程序中內置(built-in)的默認配置.
檢測redis服務器是否啟動
重新打開一個終端窗口，輸入命令
$ redis-cli ping
該終端輸出
pong
說明服務器運作正常。
關閉redis
關閉redis有2種方法：
方法1
在執行啟動命令的終端窗口使用ctrl+c,此時第一個窗口輸出
8773:M 11 Sep 21:46:26.581 # User requested shutdown... 8773:M 11 Sep 21:46:26.581 * Saving the final RDB snapshot before exiting. 8773:M 11 Sep 21:46:26.583 * DB saved on disk 8773:M 11 Sep 21:46:26.583 * Removing the pid file. 8773:M 11 Sep 21:46:26.583 # Redis is now ready to exit, bye bye...
然后在另外一個終端窗口執行$ redis-cli ping,輸出
Could not connect to Redis at 127.0.0.1:6379: Connection refused
說明確實已關閉
方法2
在另外一個終端窗口執行$ redis-cli shutdown,此時第一個窗口輸出
8773:M 11 Sep 21:46:26.581 # User requested shutdown... 8773:M 11 Sep 21:46:26.581 * Saving the final RDB snapshot before exiting. 8773:M 11 Sep 21:46:26.583 * DB saved on disk 8773:M 11 Sep 21:46:26.583 * Removing the pid file. 8773:M 11 Sep 21:46:26.583 # Redis is now ready to exit, bye bye...
然后在另外一個終端窗口執行$ redis-cli ping,輸出
Could not connect to Redis at 127.0.0.1:6379: Connection refused
說明確實已關閉
安裝phpredis擴展
brew install php70-redis #這里根據你的PHP版本決定，我的是php70，所以安裝php70的擴展
編輯你的php.ini，再最后添加上下面代碼：
extension=redis.so
檢查是否有redis擴展
php -m | grep redis
最后PHP測試代碼：
<?php $redis = new redis(); $redis->connect('127.0.0.1', 6379); $redis->set('test',"11111111111"); $result = $redis->get('test'); var_dump($result); ?>
