问题描述
报错日志如下：
...
[ ERROR ] fatal: [localhost -> 192.168.222.93]: FAILED! => {changed: false, msg: Failed to download metadata for repo 'centos-ceph-pacific': Cannot prepare internal mirrorlist: Curl error (28): Timeout was reached for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-ceph-pacific [Connection timed out after 30000 milliseconds], rc: 1, results: []}
...
原因
离线安装导致不能访问源。
解决
方法1
采用离线安装模式执行安装
# hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true
参数说明：
- --4表示只使用IPv4模式；
- --ansible-extra-vars=he_offline_deployment=true表示离线模式，不进行更新。
方法2
在虚拟机部署前中断部署流程，重新配置可以访问的源地址，如代理/私有镜像地址。具体部署命令为
# hosted-engine --deploy --4 --ansible-extra-vars=he_pause_before_engine_setup=true
说明：具体部署时会暂停，同时通过展示的滚动日志了解到engine虚拟机的地址，结合之前部署时给engine虚拟的root账户配置的密码，通过ssh的方式连接进入虚拟机，修改源后保存退出。删除宿主机（即执行hosted-engine部署命令的主机）中滚动日志指定的暂停锁定文件，继续engine的部署流程。
附hosted-engine ansible-extra-vars参数参考
