当我尝试启动mongodb时，我收到此错误：
initAndListen中的[initandlisten]异常：20尝试在只读目录上创建锁定文件：/ mnt / data / mng，终止
我正在使用centos 7.3而且我不知道我是否可以成为与se_linux相关的问题......
如您所见，我设置mongo存储目录位于/mnt/data/mng。这个问题似乎与某种权限有关。我看了看那里：
# ls -lha /mnt/data/
drwxr-xr-x. 3 root root 17 Jun 1 10:01 .
drwxr-xr-x. 3 root root 18 Jun 1 10:01 ..
drwxr-xr-x. 2 mongod mongod 6 Jun 1 10:01 mng
您可以在此处看到完整的消息：
