MongoNetworkError: connect ECONNREFUSED after update

问题

在更新了Linux之后，我无法启动MongoDB。

[ec2-user@ip-172-31-28-249 mongodb]$ sudo systemctl start mongod

当我尝试连接MongoDB Shell时，我得到了以下错误：

[ec2-user@ip-172-31-28-249 mongodb]$ mongosh
Current Mongosh Log ID: 63fc6638bdf3ce7a41cefff7

在mongod.log中，我得到了以下信息：

端口27017是开放的。您可以尝试执行以下操作来解决此错误：

  1. 检查mongod的配置文件，确保它与更新后的系统兼容。
  2. 检查MongoDB日志文件以获取更多有关连接问题的信息。
  3. 检查MongoDB服务是否正在运行，使用sudo systemctl status mongod命令。
  4. 确保防火墙或安全组未阻止MongoDB端口（27017）的访问。
  5. 尝试手动启动MongoDB服务，使用sudo mongod命令，并查看是否有任何错误消息。
  6. 确保MongoDB的数据目录正确配置。

请注意，错误信息中提到找不到pid文件，您可能需要检查MongoDB配置文件中的pid文件路径，以确保它存在并具有正确的权限。

After updating linux i can't start my mongodb.

The PORT 27017 is open
MongoNetworkError: connect ECONNREFUSED after update

what can i do to fix this error?

请检查您的服务文件 /usr/lib/systemd/system/mongod.service。

通常情况下，它应该包含以下内容：

[Service]
User=mongod
Group=mongod
Environment="OPTIONS=-f /etc/mongod.conf"
EnvironmentFile=-/etc/sysconfig/mongod
ExecStart=/usr/bin/mongod $OPTIONS
ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb
ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb
ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb
PermissionsStartOnly=true
PIDFile=/var/run/mongodb/mongod.pid

我假设文件夹 /var/run/mongodb 已被删除（参见硬重启后/var/run中的目录被删除），因此您必须在启动服务时创建它并授予相应的权限。

请注意，您不应直接编辑文件 /usr/lib/systemd/system/mongod.service。而是创建一个副本，保存在 /etc/systemd/system/mongod.service，然后根据您的需求修改此副本。

英文:

Check your service file /usr/lib/systemd/system/mongod.service

Usually it should contain lines like these:

[Service]
User=mongod
Group=mongod
Environment="OPTIONS=-f /etc/mongod.conf"
EnvironmentFile=-/etc/sysconfig/mongod
ExecStart=/usr/bin/mongod $OPTIONS
ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb
ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb
ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb
PermissionsStartOnly=true
PIDFile=/var/run/mongodb/mongod.pid

I assume folder /var/run/mongodb was deleted (see
Directory in /var/run gets deleted after hard reboot), thus you must create it and grant permissions when service is started.

Note, you should not edit file /usr/lib/systemd/system/mongod.service directly. Instead create a copy at /etc/systemd/system/mongod.service and modify this copy according to your needs.
