Travis Permission Denied Bash Script

Note to self

Running a travis build script, if you get an error like the following:

$ ./travis/setup-mysql.sh
/home/travis/build.sh: line 145: ./travis/setup-mysql.sh: Permission denied
The command "./travis/setup-mysql.sh" failed and exited with 126 during before_script.
Your build has been stopped.

The solution is to chmod the bash script in your travis file:

before_script:
 - chmod +x ./travis/setup-mysql.sh
