可見只有在開發和測試階段才考慮使用默認配置文件,正式環境最好仍是提供自定義的配置文件,而且通常命名爲redis.conf
在Redis的官網下載頁上有各類各樣的版本,因爲redis官網不支持windows,可是咱們偉大的windows家族仍是召喚了一羣小夥伴開發了win版的redis。要在windows上部署的,要去GitHub上下載。html
下載完成你會看到一個Redis-x64.rar,文件解壓文件出現如圖的結構:node
下面介紹兩種啓動方式:git
第一種、直接運行redis-server.exe文件,你會看到一個彈出命令框:github
這樣redis就啓動了,redis
第二種,在解壓的redis目錄下運行windows
redis-server redis.windows.conf
結果就悲劇了,提示:服務器
QForkMasterInit: system error caught. error code=0x000005af, message=VirtualAllocEx failed.: unknown error
緣由是內存分配的問題。解決方法有兩個,第一:啓動的時候使用--maxmemory
命令限制Redis的內存:app
redis-server redis.windows.conf --maxmemory 200m
第二種方法就是修改配置文件redis.windows.conf
:less
maxmemory 209715200
注意單位是字節,改完後以下:tcp
以後再運行redis-server redis.windows.conf
就能夠啓動了:
可是這種方式關閉cmd窗口就會關閉Redis,難道服務器上要一直開着嗎?這顯然是不科學的,下面看怎麼在服務器上部署。
下面咱們來看怎樣把redis部署到windows上的,這樣實現了咱們想要的開機自啓動。
redis-server --service-install redis.windows.conf
安裝完以後,就可看到Redis已經做爲windows服務了:
可是安裝好以後,Redis並無啓動,啓動命令以下:
redis-server --service-start
這樣就在windows下部署完成,並啓動了。
中止命令:
redis-server --service-stop
還能夠安裝多個實例並命名這些實例
redis-server --service-install –service-name redisService1 –port 10001 redis-server --service-start –service-name redisService1 redis-server --service-install –service-name redisService2 –port 10002 redis-server --service-start –service-name redisService2 redis-server --service-install –service-name redisService3 –port 10003 redis-server --service-start –service-name redisService3
卸載命令:
redis-server --service-uninstall
最後提示一下:2.8版本的不支持32位系統,32位系統要去下載2.6版本的。2.6版本的沒法像上面同樣方便的部署,它提供一個叫RedisWatcher的程序來運行redis server,Redis中止後會自動重啓。

redis的安裝方法有2種:下載源碼編譯安裝和使用homebrew安裝。本文采用後一種方法,如需下載源碼編譯安裝參考 mac下安裝配置redis。執行如下命令:
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
從以上日誌輸出能夠看出,若是須要給redis服務端指定配置文件,啓動命令應該是這樣的:
$ redis-server /usr/local/etc/redis.conf
經測試直接使用如下命令也能夠啓動:
$ redis-server
終端打印日誌以下:

能夠看到啓動時不指定配置文件會使用默認配置文件。
默認的配置文件就是使用homebrew安裝時提示的/usr/local/etc/redis.conf,使用cat命令查看:
$ cat /usr/local/etc/redis.conf

官網上對於默認文件的描述:
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.
可見只有在開發和測試階段才考慮使用默認配置文件,正式環境最好仍是提供自定義的配置文件,而且通常命名爲redis.conf
