答案 0 :(得分：4)
您需要/ data / db /
的读/写权限答案 1 :(得分：1)
错误显示，因为您没有以root用户身份登录。要做到这一点（如果你使用Debian），运行：
sudo mongod
或者简单地说：
su root
然后输入密码并输入
mongod
然后你就可以访问了 / data / db目录。
答案 2 :(得分：0)
我删除了/data/db/mongod.lock来解决问题。
答案 3 :(得分：0)
从命令行运行：
如果你仍然无法运行它，那么找到/ data目录（它应该在〜或〜/ workspace中）并cd进去。进入后，运行rm mongod.lock然后再回到〜并再次运行./mongod（见下文）。
