docker拉取mysql镜像报错Error response from daemon

Error response from daemon: Head https://registry-1.docker.io/v2/library/mysql/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Alibrary%2Fmysql%3Apull&service=registry.docker.io: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

1.通过dig @114.114.114.114 registry-1.docker.io找到可用IP

[root@localhost ~]# dig @114.114.114.114 registry-1.docker.io

; <<>> DiG 9.11.4-P2-RedHat-9.11.4-26.P2.el7 <<>> @114.114.114.114 registry-1.docker.io

2.修改/etc/hosts强制docker.io相关的域名解析到其它可用IP，添加34.231.251.252并保存。

vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
34.231.251.252 registry-1.docker.io

3.再次拉取

[root@localhost ~]# docker pull mysql
