Redis基礎系列-0x001：安裝與鏈接測試

0x001：mac上安裝
mac上安裝使用homebrew便可，安裝中有許多重要的信息，因此這裏不作省略，並在如下的輸出中作一些註釋。

# 輸入
$ brew install redis

# 輸出

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:
# 這裏是一些工具的位置，又須要能夠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:
# 這裏是啓動服務端的方法，其中包含了默認配置文件的位置
  redis-server /usr/local/etc/redis.conf
==> Summary
🍺  /usr/local/Cellar/redis/4.0.9: 13 files, 2.8MB

0x002：啓動服務端
看到如下redis圖標圖案說明啓動成功，而且能夠從輸出中看出啓動的進程號和端口號
