1、新安装mongodb，执行sudo service mongod start（sudo service mongod restart），都报启动失败。

    查看/var/log/mongodb/mongod.log：

     解决步骤：

      1、删除日志文件/var/log/mongodb/mongod.log

rm /var/log/mongodb/mongod.log

      2、删除lock文件

rm /var/log/mongodb/mongod.log

      3、执行修复

sudo /usr/bin/mongod --repair --dbpath /var/lib/mongodb / --repairpath /tmp/mongodb
