【解决过程】
1.搜：
openfire HTTP ERROR 500 Problem accessing setup-profile-settings.jsp
参考：
Help ! OpenFire crashes while configuring ! | Ignite Realtime
安装OpenFire时出现HTTP ERROR 500问题的解决 – 云人生 – 51CTO技术博客
去关闭OpenFire并重启：
[root@bogon ~]# service openfire stop Shutting down openfire: [ OK ] [root@bogon ~]# service openfire restart Shutting down openfire: kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] Starting openfire: [root@bogon ~]# service openfire status openfire is running [root@bogon ~]#
然后进入：
继续重新配置：
果然可以继续配置了：
【总结】
当配置OpenFire在 特性设置 时，出现：
HTTP ERROR 500 Problem accessing /setup/setup-profile-settings.jsp Reason Server Error
错误，则去重启OpenFire：
service openfire stop service openfire restart
然后重新进入主页：
重新配置即可。
