安裝redis
redis的安裝方法有2種：下載源碼編譯安裝和使用homebrew安裝察皇。本文采用后一種方法痪宰，如需下載源碼編譯安裝參考 mac下安裝配置redis又兵。通過(guò)homebrew安裝redis:
$ brew install redis

==> Downloading http://download.redis.io/releases/redis-3.2.3.tar.gz

==> 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销钝，如果需要給redis服務(wù)端指定配置文件跨扮，啟動(dòng)命令應(yīng)該是這樣的:
$ redis-server /usr/local/etc/redis.conf
配置文件
安裝完成后redis默認(rèn)的配置文件redis.conf位于
/usr/local/etc
同時(shí)，redis-sentinel.conf也在這里携龟。
使用cat命令查看redis.conf：
$ cat /usr/local/etc/redis.conf

官網(wǎng)上對(duì)于如何配置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(jù)以上內(nèi)容,如果啟動(dòng)時(shí)不指定配置文件,redis會(huì)使用程序中內(nèi)置的默認(rèn)配置.但是只有在開(kāi)發(fā)和測(cè)試階段才考慮使用內(nèi)置的默認(rèn)配置，正式環(huán)境最好還是提供配置文件勘高，并且一般命名為redis.conf
啟動(dòng)redis
可以通過(guò)以下命令啟動(dòng)redis：
$ redis-server /usr/local/etc/redis.conf &

可以看出redis服務(wù)器啟動(dòng)成功峡蟋，并在監(jiān)聽(tīng)6379端口的網(wǎng)絡(luò)連接。
注意: 使用命令$ redis-server也可以啟動(dòng),此時(shí)并不會(huì)加載任何配置文件,使用的是程序中內(nèi)置(built-in)的默認(rèn)配置.
檢測(cè)redis服務(wù)器是否啟動(dòng)
重新打開(kāi)一個(gè)終端窗口华望，輸入命令
$ redis-cli ping
該終端輸出
pong
說(shuō)明服務(wù)器運(yùn)作正常蕊蝗。
關(guān)閉redis
關(guān)閉redis有2種方法：
方法1
在執(zhí)行啟動(dòng)命令的終端窗口使用ctrl+c,此時(shí)第一個(gè)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(gè)終端窗口執(zhí)行$ redis-cli ping,輸出
Could not connect to Redis at 127.0.0.1:6379: Connection refused
說(shuō)明確實(shí)已關(guān)閉
方法2
在另外一個(gè)終端窗口執(zhí)行$ redis-cli shutdown,此時(shí)第一個(gè)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 # Redis is now ready to exit, bye bye...
然后在另外一個(gè)終端窗口執(zhí)行$ redis-cli ping,輸出
Could not connect to Redis at 127.0.0.1:6379: Connection refused
說(shuō)明確實(shí)已關(guān)閉
