Redis在Mac Mavericks上的环境设置

使用Homebrew进行安装。

因为我想在Mac开机时自动启动，所以我会使用launchctl进行设置。

请参考以下链接：http://qiita.com/checkpoint/items/58b9b0193c0c46400eeb

$ brew install redis

To have launchd start redis at login:
    ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents
Then to load redis now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
Or, if you don't want/need launchctl, you can just run:
    redis-server /usr/local/etc/redis.conf
==> Summary
?  /usr/local/Cellar/redis/2.8.8: 10 files, 1.3M

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist

我相信大多数人只要做到这一步就可以无错误地启动。
但是对我来说，发生了错误。

因为无法顺利启动，所以我要调查一下原因。

$ redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> 

$  redis-server /usr/local/etc/redis.conf

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 369
>>> 'vm-enabled no'
Bad directive or wrong number of arguments

当查看/usr/local/Cellar/redis/时，发现早些时候安装的版本2.4.6仍在其中。

看了一下设置文件，时间戳大约是在2012年左右。
根据上述错误看，我觉得当启动新安装的2.8.8版本时，它似乎直接读取了2.4.6版本的设置文件。

因此，我先卸载了全部的Redis，然后删除了配置文件（/usr/local/etc/redis.conf、/usr/local/etc/redis-sentinel.conf），再重新安装了Redis。

$ brew remove redis
Uninstalling /usr/local/Cellar/redis/2.8.8...
$ brew remove redis
Uninstalling /usr/local/Cellar/redis/2.4.6...

$ rm /usr/local/etc/redis.conf /usr/local/etc/redis-sentinel.conf

$ brew install redis

To reload redis after an upgrade:
    launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
==> Summary
?  /usr/local/Cellar/redis/2.8.8: 10 files, 1.3M

$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist

在我做到这一步并在命令行上确认了行为后，它成功地运行了。

$ redis-cli
127.0.0.1:6379> set keyfuga fugafuga
OK
127.0.0.1:6379> get keyfuga
"fugafuga"
