Can't launchctl start redis

[mcho421]

When I try to launchctl start redis, it complains there is no such process:

$ launchctl start ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
launchctl start error: No such process

I saw <key>RunAtLoad</key> in the plist, so maybe that is related?

More info:

$ brew info redis
redis: stable 3.0.4 (bottled), HEAD
Persistent key-value database, with built-in net interface
http://redis.io/
/usr/local/Cellar/redis/3.0.4 (10 files, 908K) *
  Poured from bottle
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/redis.rb
==> Options
--with-jemalloc
    Select jemalloc as memory allocator when building Redis
--HEAD
    Install HEAD version
==> Caveats
To reload redis after an upgrade:
  launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
  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

$ redis-server -v
