Autostart App on Macintosh, just load PLIST files at LaunchAgents such as (Mysql, Mongod and Redis)

Mysql 

brew info mysql

mkdir -p ~/Library/LaunchAgents

cp `brew --prefix mysql`/*mysql*.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/*mysql*.plist

or 

cp /usr/local/opt/mysql/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

Mongod 

Create a file call org.mongo.mongod.plist in /Library/LaunchDaemons/

If you use vim you can do like this:

sudo vim /Library/LaunchDaemons/org.mongo.mongod.plist  

Copy and paste this:

 

 

"1.0">  

 

    Label

    org.mongo.mongod

    RunAtLoad

   

    ProgramArguments

   

        /usr/local/bin/mongod

        --dbpath

        /var/lib/mongodb/

        --logpath

        /var/log/mongodb.log

   

 

Also, you will need to create a file for the log and a directory for the database.

sudo touch /var/log/mongodb.log  

sudo mkdir /var/lib/mongodb  

And run this in your terminal:

sudo chown root:wheel /Library/LaunchDaemons/org.mongo.mongod.plist  

sudo launchctl load /Library/LaunchDaemons/org.mongo.mongod.plist  

sudo launchctl start org.mongo.mongod  

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
