Configure accounts for authentication

Optimization Solver requires a license to solve problems. After you purchase the service, you can see the license key on the Available Service List page. You can use the license key to configure the license file fl_client.ini. For information about how to obtain the license file, see Step 4: Configure license files. We recommend that you use the environment variable MINDOPT_LICENSE_PATH to specify a location for storing the license file. If the fl_client.ini file does not exist, create one, copy the following sample content to the file, and modify the content based on your business requirements.

[security]
# key for client authentication 
aliyun_license_key = xxx # Change the value of this parameter to the license key of the service that you purchase. You can obtain the license key from the Available Service List page of the Optimization Solver console.

aliyun_ak_id= xxx # Change the value of this parameter to the AccessKey ID of your Alibaba Cloud account or Resource Access Management (RAM) user.

aliyun_ak_secret= xxx # Change the value of this parameter to the AccessKey secret of your Alibaba Cloud account or RAM user.

# Copy the following content. You do not need to modify the content unless otherwise required.
[server]
# license server host
name = opt.us-east-1.aliyuncs.com #opt.cn-beijing.aliyuncs.com # Change the name to the endpoint of the region where you purchase 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
