docker-compose标准化部署MongoDB

mkdir /data/mongo/{data,log,config} -p

cd  /data/mongo

cat > /data/mongo/config/mongod.conf   << EOF

如果要搭建的是单机版的副本集，需要添加replication 参数并连接到数据库后，执行rs.initiate

cat >> /data/mongo/config/mongod.conf   << EOF
replication:
  replSetName: rs0
EOF


rs.initiate()


如果需要搭建的是单机版的副本集，直接启动即可

docker-compose up -d

docker ps -a

docker logs -f --tail 100 mongo27017

mongo   --host 10.2.29.80 --port 27017  -uadmin -padmin    --authenticationDatabase admin
