Redis

0x001：mac上安裝
mac上安裝使用homebrew即可，安裝中有許多重要的資訊，所以這裡不做省略，並在以下的輸出中做一些註釋。

# 輸入
$ brew install redis

# 輸出
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/redis-4.0.9.high_sierra.bot

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/redis-benchmark
Target /usr/local/bin/redis-benchmark
already exists. You may want to remove it:
  rm `/usr/local/bin/redis-benchmark`

To force the link and overwrite all conflicting files:
  brew link --overwrite redis

To list all files that would be deleted:
  brew link --overwrite --dry-run redis

Possible conflicting files are:
# 這裡是一些工具的位置，又需要可以直接從下面路徑找到相應工具
/usr/local/bin/redis-benchmark
/usr/local/bin/redis-check-aof
/usr/local/bin/redis-check-rdb
/usr/local/bin/redis-cli
/usr/local/bin/redis-sentinel -> /usr/local/bin/redis-server
/usr/local/bin/redis-server
==> 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:
# 這裡是啟動服務端的方法，其中包含了預設配置檔案的位置
  redis-server /usr/local/etc/redis.conf
==> Summary
?  /usr/local/Cellar/redis/4.0.9: 13 files, 2.8MB

0x002：啟動服務端
看到以下redis圖示圖案說明啟動成功，並且可以從輸出中看出啟動的程式號和埠號
