mongodb 运行错误总结

1、查看服务起来(端口号)

netstat -ntlp |grep 27017

2、启动mongodb

 ./mongod

遇到错误：

原因：mongodb启动如果不指定路径，默认加载/data/db

解决方法：启动加上dbpath

后台运行：

./mongod --dbpath=/home/mongo/mongodb/data/db --fork --logpath=/home/mongo/mongodb/logs/mongod.log

3、启动mongod，进入管理员界面

 ./mongod --dbpath=/home/mongo/mongodb/data/db
 ./mongo

注意：保持原界面不变，打开新界面输入管理台
