mongdb启动报错

2018-08-19T12:25:31.707+0800 I CONTROL [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
about to fork child process, waiting until server is ready for connections.

ERROR: child process failed, exited with error number 100
To see additional information in this output, start without the "--fork" option.

今天在我的centeros7上安装mongodb启动时报了这个错

查看日志发现是配置文件的问题

配置文件 mongodb.conf

port = 27017
dbpath = data/
logpath = ../log/mongod.log
directoryperdb = true
fork = true

dbpath更正为../data/

启动成功
