遠程連接ubuntu的MongoDB遇到的坑

• 首先連接不上，先查看雲服務器上的安全組是否添加了對應的端口
• 如果打開了，那么久查看MongoDB是否允許遠程連接

# mongod.conf

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

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0

重點查看net下的bindIp，如果是127.0.0.1的話就改成0.0.0.0

使用啟動命令：

sudo systemctl start mongod

因為使用

sudo service mongodb start

會報錯

查看MongoDB的日志：

cat /var/log/mongodb/mongod.log

如果報錯是：

Detected unclean shutdown - /var/lib/mongodb/mongod.lock is not empty.

那就直接刪除掉那個文件

rm -rf /var/lib/mongodb/mongod.lock

如果報錯為：

Failed to unlink socket file /tmp/mongodb-27017.sock Operation not permitted

那就直接刪除掉那個文件：

rm -rf /tmp/mongodb-27017.sock

如果報錯為：

WiredTiger error (13) [1543829280:361502][14474:0x7f42abbdad00], file:WiredTiger.wt, connection: /var/lib/mongodb/WiredTiger.turtle: handle-open: open: Permission denied

那就提升權限：

sudo chown -R mongodb:mongodb /var/lib/mongodb

然后使用

sudo systemctl start mongod

啟動即可
