Configure authentication account information

MindOpt requires a license to solve problems. After purchasing the service, obtain your LicenseKey from the list of purchased services. Use this key to configure the fl_client.ini authentication file. For information about the file location, see 4. Configure the authentication file in the installation steps. You can also set the MINDOPT_LICENSE_PATH environment variable to specify the file's location. If the fl_client.ini file does not exist, create it. Then, copy the following example content into the file and modify it.

The following is an example of the content in the fl_client.ini file. Note: To copy the following content, click 'Open in Documentation Center' in the lower-left corner of this page because the copy function in the pop-up window does not work correctly.

[security]
# key for client authentication 
aliyun_license_key = xxx # Replace xxx with your LicenseKey. You can find it in the list of purchased services in the console (as described in the Activate service section).

aliyun_ak_id= xxx # Replace xxx with your Alibaba Cloud account's AccessKey ID.

aliyun_ak_secret= xxx # Replace xxx with your Alibaba Cloud account's AccessKey secret.

# After you copy the following content, do not change it unless necessary.
[server]
# license server host
name = opt.cn-beijing.aliyuncs.com # Replace this with the endpoint of the region where you purchased the service.

# license server port 80 if absent
port = 443

# license server is https protocol
https = true

# client side request timeout in second
request_timeout  =   2

Where:

The account configurations to modify in the fl_client.ini file are as follows:

1. In the security section, set aliyun_license_key to your LicenseKey. You can find the LicenseKey on the Console > List of Purchased Services page. If you have not purchased the service, follow the instructions in the 'Activate the service' section to activate and purchase it.

2. In the security section, replace the values of aliyun_ak_id and aliyun_ak_secret with the AccessKey pair of your Alibaba Cloud account or RAM user.

   Note

   How to create an AccessKey pair:

   In the upper-right corner of the console page, hover over your profile picture. In the menu that appears, click AccessKey Management.

   You can also watch the following tutorial, which demonstrates operations in the Professional Edition:

   • Alibaba Cloud account: To create an AccessKey pair for an Alibaba Cloud account, go to AccessKey Management.

   • RAM user: If you use a RAM user, create an AccessKey pair. For more information, see Create an AccessKey pair for a RAM user. After you create the AccessKey pair, the root account must grant the RAM user permission to manage Optimization Solver.
