Can't get my mac launchd script to run for mysql - mysql

Question

So I've installed mysql on my mac server and I'm trying to get it to run via launchd.
My command for starting up the server from cmd line is as follows:
mysqld --user=_mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --log-error=/usr/local/mysql/data/mysqld.local.err --pid-file=/usr/local/mysql/data/mysqld.local.pid --port=3306 --tmpdir=/tmp
This is my plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<string>--tmpdir=/tmp</string>
</array>

<string>/usr/local/mysql</string>
</dict>
</plist>
This is the error I'm getting from the system.log:
Oct 9 11:10:28 PMAs-Mac-Pro com.apple.xpc.launchd[1] (com.oracle.oss.mysql.mysqld[1190]): Service could not initialize: 15A284: xpcproxy + 12644 [1472][19011403-4854-3CCD-9FCF-49C36302EB40]: 0xd
Oct 9 11:10:28 PMAs-Mac-Pro com.apple.xpc.launchd[1] (com.oracle.oss.mysql.mysqld): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
From my understandings, this is a permissions error. I've made sure that /usr/local/mysql is owned my _mysql, so I'm not sure what the problem is there.
I've also double checked the permission of the plist file:
-rw-r--r-- 1 root wheel 1607 Oct 9 11:42 /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
