Connecting to a Single Node Instance Using Mongo Shell (Private Network)

For details about how to install a MongoDB client, see How Can I Install a MongoDB Client?

The following describes how to upload the certificate to a Linux and Window ECS:

• In Linux, run the following command:
  scp<IDENTITY_FILE><REMOTE_USER>@<REMOTE_ADDRESS>:<REMOTE_DIR>

  

  • IDENTITY_FILE is the directory where the root certificate resides. The file access permission is 600.
  • REMOTE_USER is the ECS OS user.
  • REMOTE_ADDRESS is the ECS address.
  • REMOTE_DIR is the directory of the ECS to which the root certificate is uploaded.

• In Windows, upload the root certificate using a remote connection tool.

Method 1: Private HA connection address (recommended)

Example command:

./mongo <Private network HA connection address> --ssl --sslCAFile<FILE_PATH> --sslAllowInvalidHostnames

Parameter description:

• Private HA Connection Address: On the Instances page, click the instance name. The Basic Information page is displayed. Choose Connections. Click the Private Connection tab and obtain the connection address of the current instance from the Private Network Connection Address field.
  Figure 1 Obtaining the private HA connection address
  

  The format of the private connection address is as follows. The database username rwuser and authentication database admin cannot be changed.

  mongodb://rwuser:<password>@192.168.xx.xx:8635/test?authSource=admin

  Pay attention to the following parameters in the private network connection address:

  Table 1 Parameter description

  Parameter	Description
  rwuser	Database username
  <password>	Password for the database username. Replace it with the actual password. If the password contains at signs (@), exclamation marks (!), or percent signs (%), replace them with hexadecimal URL codes (ASCII) %40, %21, and %25 respectively. For example, if the password is ****@ %***!, the corresponding URL code is **** %40%25*** %21.
  192.168.xx.xx:8635	IP address and port of the single node instance to be connected
  test	The name of the test database. You can set this parameter based on your service requirements.
  authSource=admin	The authentication database of user rwuser must be admin. authSource=admin is fixed in the command.

• FILE_PATH is the path for storing the root certificate.
• --sslAllowInvalidHostnames: To ensure that the internal communication of the single nodes does not occupy resources such as the user IP address and bandwidth, the single node certificate is generated using the internal management IP address. --sslAllowInvalidHostnames is needed for the SSL connection over private networks.

Command example:

./mongo mongodb://rwuser:<password>@192.168.xx.xx:8635/test?authSource=admin --ssl --sslCAFile/tmp/ca.crt --sslAllowInvalidHostnames

Method 2: Private HA connection (user-defined database and account)

Example command:

./mongo <Private network HA connection address>

Parameter description:

• Private HA Connection Address: On the Instances page, click the instance name. The Basic Information page is displayed. Choose Connections. Click the Private Connection tab and obtain the connection address of the current instance from the Private HA Connection Address field.
  Figure 2 Obtaining the private HA connection address
  

  The format of the obtained private HA connection address is as follows:

  mongodb://rwuser:<password>@192.168.xx.xx:8635/test?authSource=admin

  The following table lists the required parameters in the private HA address.

  Table 2 Parameter information

  Parameter	Description
  rwuser	Database username. The default value is rwuser. You can change the value to the username based on your service requirements.
  <password>	Password for the database username. Replace it with the actual password. If the password contains at signs (@), exclamation marks (!), or percent signs (%), replace them with hexadecimal URL codes (ASCII) %40, %21, and %25 respectively. For example, if the password is ****@ %***!, the corresponding URL code is **** %40%25*** %21.
  192.168.xx.xx:8635	IP address and port of the single node instance to be connected
  test	The name of the test database. You can set this parameter based on your service requirements.
  authSource=admin	The authentication database of user rwuser is admin. NOTE: If you use a user-defined database for authentication, change the authentication database in the HA connection address to the name of the user-defined database. In addition, replace rwuser with the username created in the user-defined database.

• FILE_PATH is the path for storing the root certificate.
• --sslAllowInvalidHostnames: To ensure that the internal communication of the single nodes does not occupy resources such as the user IP address and bandwidth, the single node certificate is generated using the internal management IP address. --sslAllowInvalidHostnames is needed for the SSL connection over private networks.

For example, if you create a user-defined database Database and user test1 in the database, the connection command is as follows:

./mongo mongodb://test1:<password>@192.168.xx.xx:8635/Database?authSource=Database --ssl --sslCAFile/tmp/ca.crt --sslAllowInvalidHostnames

Method 3: Using a private IP address

Example command:

./mongo --host <DB_HOST> --port <DB_PORT> -u <DB_USER> -p --authenticationDatabase admin --ssl --sslCAFile<FILE_PATH> --sslAllowInvalidHostnames

Parameter description:

• DB_HOST is the private IP address of the instance to be connected.

  On the Instances page, click the instance name. The Basic Information page is displayed. Choose Connections. On the Private Connection tab, obtain the IP address of the corresponding node. Obtaining the private IP address

  

• DB_PORT is the database port. The default port number is 8635.

  You can click the instance name to go to the Basic Information page. In the navigation pane on the left, choose Connections. On the displayed page, click the Private Connection tab and obtain the port from the Database Port field in the Basic Information area.
