exception: connect failed

首先明白就是链接失败，是否是服务器重启，mongo服务没有设置自动启动，可以首先启动mongo服务再试试

启动MongoDB

$ sudo systemctl start mongod.service

查看是否启动成功

$ sudo systemctl status mongod.service

若显示 active（running）则启动成功！或者

$ sudo cat /var/log/mongodb/mongod.log

如出现 [thread1] waitingforconnectionsonport

其中的默认为27017，在 /etc/mongod.conf中配置，则启动成功！
