ERROR Permission denied: make_sock: could not bind to address [::]:5000

systemctl start httpd journalctl -xe 具体报错如下：

    ...
    Permission denied: make_sock: could not bind to address [::]:5000
    Permission denied: make_sock: could not bind to address 0.0.0.0:5000
    ...

解决方案

[root@controller ~]# vi /etc/selinux/config
    ...
    SELINUX=enforcing
改为
    SELINUX=disable

然后重启 reboot

OTHER

[root@controller ~]# source adminRC
[root@controller ~]# openstack user list
The service catalog is empty.

解决方案

RC文件内容有误(我的是字母大小写错误导致)，编辑后重新 source adminRC
