Question

我有一个CentOS 7空VM。

> hostnamectl

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.
systemLog:

  logAppend: true
  path: /mongo/logs #/var/log/mongodb/mongod.log

# Where and how to store data.

当我尝试开始时，我收到此错误：

> service mongod start
   Starting mongod (via systemctl):  Job for mongod.service failed. See 'systemctl status mongod.service' and 'journalctl -xn' for details

和

> journalctl -xn

有没有人遇到过这个问题＆＃34;无法启动SYSV＆＃34;？

欢迎任何帮助或提示。谢谢，保罗

root问题是selinux权限，默认情况下在CentOS 7中启用。可以通过禁用selinux或将正确的上下文添加到mongo数据库路径来修复：

chcon -R -t mongod_var_lib_t /var/lib/mongod

无法在CentOS7上启动MongoDB
