1.修改apache服务器配置文件
/etc/httpd/conf.d/15-horizon_vhost.conf
- <VirtualHost *:80> + <VirtualHost *:8082>
/etc/httpd/conf.d/ports.conf
- Listen 80
- NameVirtualHost *:80
+ Listen 8082
+ NameVirtualHost *:8082
2.重启 httpd 服务
[root@cat ~]# service httpd restart
3.如果重启httpd服务时有下列错误，需要把port加到SElinux里（需要确保port是没有被使用的）
Permission denied: make_sock: could not bind to address [::]:5678
[root@cat ~]# semanage port -a -t http_port_t -p tcp 5678
[Icehouse][horizon] 改horizon的url访问端口
