If you are Windows or Mac OS X user, you can try out docker-oj, based on docker image and works out of the box.

docker run --link your_mongo:mongodb --name oj  -e DATA_PATH=your_data_path -e JUDGE_HOST=your_judge_host -v your_data_path:your_data_path -d -p 80:8080 oj

If you installed mongodb on your host os, use script like this:

cat > env_file <<EOF
MONGODB_USERNAME=test
MONGODB_PASSWORD=password

EOF

docker run --env-file env_file --name oj -v your_data_path:your_data_path -d -p 80:8080 oj

####Install

Obtain latest version via git, source codes will be in your $GOPATH/src.

git clone https://github.com/ZJGSU-Open-Source/GoOnlineJudge.git $GOPATH/src/GoOnlineJudge
git clone https://github.com/ZJGSU-Open-Source/RunServer.git $GOPATH/src/RunServer
git clone https://github.com/ZJGSU-Open-Source/vjudger.git $GOPATH/src/vjudger
git clone https://github.com/sakeven/restweb.git $GOPATH/src/restweb

# Set $OJ_HOME variable
export OJ_HOME="yourself oj home" #e.g. export OJ_HOME=/$GOPATH/src
export DATA_PATH=$OJ_HOME/Data
export LOG_PATH=$OJ_HOME/log
export RUN_PATH=$OJ_HOME/run
export JUDGE_HOST=your_judge_host #e.g. export JUDGE_HOST="http://127.0.0.1:8888"
export MONGODB_PORT_27017_TCP_ADDR=127.0.0.1
export PATH=$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:

ProblemData/  
run/  
log/  

Now, it's time for compilation.

cd $GOPATH/src/restweb
go install ./...
cd $GOPATH/src
restweb build GoOnlineJudge
cd $GOPATH/src/RunServer
./make.sh

Start OJ

RunServer&
cd $GOPATH/src
restweb run GoOnlineJudge &

Now,you can visit OJ on http://127.0.0.1:8080.

####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.
