您好，感谢您抽出宝贵时间检查我的问题我正在按照openstack的详细步骤进行安装，无济于事（https://docs.openstack.org/keystone/rocky/install/keystone-install-rdo.html）我尝试更改服务的5000端口，但结果相同任何见解都受到欢迎
[root@localhost i-openstack]# systemctl enable httpd.service
[root@localhost i-openstack]# systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

解决方案：看来我不得不禁用SELinux
暂时禁用
sudo setenforce 0
重新启动httpd服务
服务httpd重新启动
永久禁用SELinux（需要重新启动）
nano / etc / selinux / config
SELINUX =禁用
