无法启动 MongoDB，mongod 始终停止/等待

我尝试在 Ubuntu 16.04 服务器上运行 v2.6.10：

sudo service mongod start

并得到结果：

mongod start/running, process 67725

但当我检查状态时，我得到了：

mongod stop/waiting

根据该日志行，这是一个权限问题。

/data/db/mongod.lock errno:13 权限被拒绝 是 mongod ins$ 2017-09-10T07:47:16.529+0200 [initandlisten] dbexit:

看来您已将dbpath默认设置更改/var/lib/mongodb为/etc/mongodb.conf

修复 上的权限和所有权/data/db。假设您使用了包用户:组应该mongodb：mongodb因此以下命令应该可以让它在这个自定义位置工作。

更改权限以镜像包位置：

sudo chmod 755 /data/db

确保目录所有权与官方包相同：

sudo chown mongodb:mongodb /data/db
