export DATA_PATH=$OJ_HOME/Data
export LOG_PATH=$OJ_HOME/log
export RUN_PATH=$OJ_HOME/run
export JUDGE_HOST=your_judge_host #e.g. export JUDGE_HOST="http://127.0.0.1:8888"

export PATH=$PATH:$GOPATH/bin

#directory for MongoDB Data
mkdir $OJ_HOME/Data

#directory for problem set
mkdir $OJ_HOME/ProblemData

#directory for running user's code
mkdir $OJ_HOME/run

#directory for log
mkdir $OJ_HOME/log

Make sure you have these directories in your $GOPATH/src:

github.com/
GoOnlineJudge/
RunServer/
gopkg.in/
restweb/

And these directories in your $OJ_HOME:

go install ./...
cd $GOPATH/src

####Tips

You should always run MongoDB first then followed by OJ.
Running web server at 80 port requires administrator privileges. For security reasons, do not run our OJ at 80 port.
If you want to visit OJ at 80 port, nginx, the HTTP and reverse proxy server is recommended.
