mongdbd启动失败解决办法

1、vim mongo.conf

里面写如下内容：

dbpath=/usr/local/mongodb/data/

logpath=/usr/local/mongodb/logs/mongodb.log

logappend=true

port=27017

fork=true

2、启动mongod

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/mongo.conf

报错：

about to fork child process, waiting until server is ready for connections.

forked process: 2340

ERROR: child process failed, exited with error number 1

3、解决办法：

1、删除mongo.lock文件

2、/usr/local/bin/mongod --repair --dbpath=/usr/local/data

完成修复后就可以启动mongodb的客户端了！

4、启动客户端：

/usr/local/mongodb/bin/mongo

出现：

MongoDB shell version v3.4.1

connecting to: mongodb://127.0.0.1:27017

MongoDB server version: 3.4.1

就ok啦！
