rc.local 中加入 mongodb 启动命令：
/usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/db/ --logpath=/usr/local/mongodb/log/mongodb.log --logappend --fork
重启服务器后 mongo 客户端链接失败 查看 log 日志 错误如下

然后在我指定的 dbpath 目录中 (usr/local/mongodb/data/db/) 啥也没生成...
请问怎么解决啊...
你这个数据库已经启动了，应该是连接不上而已，如果是用 rails 连接的话，看看 rails log 里报什么错。dbpath 里什么都没有因为你没往数据库里写东西啊。
data 目录下有一个 mongod.lock 文件，把这个文件删掉，然后再次启动就可以了。我之前遇到和你一样的问题，在网上搜到这个方法，但是不知道什么原因，但用这个方法的确可以解决。
