流量计费it is suitable for the situation where the number of people watching the live broadcast is small, - It
宽带峰值计费is suitable for use when there are a large number of viewers. If you are not sure, you will be charged according to the traffic used.
The initial usage is not too much. After choosing to“流量计费”
activate according to the service, according to the official website process, the next step is the basic configuration of the live broadcast:域名管理
2. Access push domain name
1. Since Alibaba Cloud Live does not provide a streaming domain name, we need to access 自己的the streaming domain name. Click on the left “加速服务~添加域名”.
2. Follow the example in the picture below, fill in according to your actual situation, and then submit.
3. Go back to "Domain Name Management", and you will see the streaming domain name you just added, copy the “CNAME”value on the right side of the domain name, and go to your domain name service provider for analysis.
4. After configuring the previous step, return to the domain name management, wait a few minutes for the resolution to take effect, and you will see that the domain name status is already “正常运行”. Click on the right side of the domain name “域名配置”to enter the configuration page.
Note: It is recommended to configure first
推流. Because you will need to associate the push stream when configuring the streaming later, so configure it first
5. Click on the left “访问控制”, then modify URL鉴权the configuration, fill in the example shown in the figure below, and then submit.
Pop-up window, modify configuration
3. Access the streaming domain name
The first four steps are similar to the process of accessing the streaming domain name, so I won’t repeat them here
5. Associate push domain name.点击“基本配置~推流信息”
