docker build -t oj .
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
MONGODB_PORT_27017_TCP_ADDR=192.168.1.1
MONGODB_PORT_27017_TCP_PORT=27017
MONGODB_INSTANCE_NAME=test
DATA_PATH=your_data_path
JUDGE_HOST=your_judge_host
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.
