篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ceph——rgw服务启不起来相关的知识，希望对你有一定的参考价值。
环境：SUSE SESv5版本——对应社区ceph的L版本（12.2）
故障背景：在给ceph集群扩充第四个节点的时候，运行到stage4，报错：

sesadmin:~ #
排查思路：
在该节点上，手动启动RGW服务：
sesnode3:~ # systemctl start [email protected]
sesnode3:~ # systemctl status [email protected]
● [email protected] - Ceph rados gateway

但是依旧起不来，去查看日志

注：很奇怪，用ps命令去查看，80端口没有被使用，但是报错是80端口被占用了，为了省事所以直接一点将端口改掉：

启动服务，服务正常。
