Description This article mainly describes related operations and configurations in ECS instances. If your server is not an ECS instance, you need to ensure that the server has public Internet access capabilities, and the source address http://mirrors.cloud.aliyuncs.com needs to be replaced with http://mirrors.aliyun.com.
For example, switch the yum source to http://mirrors.aliyun.com/centos-vault/6.10/; switch the epel source to http://mirrors.aliyun.com/epel-archive/6/.
Run the following command to edit the CentOS-Base.repo file.
vim /etc/yum.repos.d/CentOS-Base.repo
Press i to enter edit mode, modify the following content to switch source.
Please modify according to the different network types of the instance, the specific content is as follows:
VPC type instance of private network
