1、vim mongo.conf里面写如下内容：dbpath=/usr/local/mongodb/data/logpath=/usr/local/mongodb/logs/mongodb.loglogappend=trueport=27017fork=true
2、启动mongod/usr/local/mongodb/bin/mongod -f /usr/lo罕铞泱殳cal/罪焐芡拂mongodb/mongo.conf报错：about to fork child process, waiting until server is ready for connections.forked process: 2340ERROR: 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 v3.4.1connecting to: mongodb://127.0.0.1:27017MongoDB server version: 3.4.1就ok啦！
