时间:2021-07-24 13:27:39

问题描述:

MongoDB启动时报下列错误

[root@MongoDB ~]# mongo
MongoDB shell version: 2.6.1
connecting to: test
2014-05-25T18:47:24.021+0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2014-05-25T18:47:24.022+0800 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed


解决方案:

1.查看保存数据库的目录是否存在

ls -ld /data/db

执行结果如下:

cuigaochongdeMacBook-Pro:~ root# ls -ld /data/db

drwxr-xr-x  7 root  wheel  238 Sep 24 16:21 /data/db


2.启动MongoDB的同时指定数据库保存在什么地方

mongod --dbpath /data/db

执行结果如下:

cuigaochongdeMacBook-Pro:~ root# mongod --dbpath /data/db

MongoDB shell version: 3.0.7

connecting to: test
