Question

我在centos 7 aws ec2实例上使用mongodb 3.6.3。

2个问题（只需要回答一个问题）：

如果使用sudo mongod --storageEngine etc
为什么sudo service mongod status显示失败？

当我运行以下命令时，（因为目前，sudo service mongod start不起作用，但下面的工作正常），当我指定--logpath但它将在没有它的情况下运行时它会失败。不幸的是，当我在没有它的情况下运行它时，我的所有日志最终都在/，这绝对是错误的位置。

sudo mongod --storageEngine wiredTiger --dbpath /data --bind_ip 127.0.0.1,apiIP --logpath /var/log/mongodb/mongod.log --auth --fork

下面是当我尝试按原样运行上面的行时发生的情况。

I CONTROL [main] log file "/var/log/mongodb/mongod.log" exists; moved to "/var/log/mongodb/mongod.log.2018-03-16T15-16-01".

据我所知，它与目前存在的

仅供参考，sudo service mongod status返回：

感谢@AlexBlex注意yaml文件中的间距问题。

如果已排序，则状态错误具有此行 Unrecognized option: storage.wiredTiger
