啦啦啦

这种情况

root@localhost:/# mongo
MongoDB shell version: 3.2.13
connecting to: test
2017-05-31T07:40:34.548-0700 W NETWORK  [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: errno:111 Connection refused
2017-05-31T07:40:34.549-0700 E QUERY    [thread1] Error: couldnt connect to server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:229:14
@(connect):1:6

exception: connect failed

由于直接kill掉的进程,不知道为什么服务再启动时options:{}为空。虽启动时指定-dbpath 参数

mongod -dbpath "/var/lib/mongodb/"

但是这样必须保证服务窗口不能关闭。

使用配置文件方式启动

mongod -f /etc/mongod.conf

这样也必须保证服务窗口不能关闭。

采用守护进程方式启动:Daemon

–fork参数可以将mongodb的服务放在后台运行

root@localhost:/# mongod -fork -f /etc/mongod.conf 
about to fork child process, waiting until server is ready for connections.
forked process: 1163
child process started successfully, parent exiting

mongod.log
