第三个mysql的日志没有返回结果。

看日志像是你的系统中有其它yum在运行，先把appnode全部停止：

appnode ccenter stop
appnode agent stop

然后查看下yum命令是否能正常输出：

yum makecache

好像是可以的。已经停止掉面板。。

yum makecache 命令执行结束后，再启动appnode，并且查看日志：

appnode ccenter start
appnode agent start
tail -n 100 /var/log/appnode/ccenter.error.log

虚竹大神请看。

你的输出看起来不太对劲啊，tail -n 100是输出最后100行，怎么你输出的还不满100行。
如果没有敏感数据，直接把 /var/log/appnode/ccenter.error.log 文件上传上来看看。

另外，看下日志 /var/log/messages 是否有 appnode 被意外中止的日志：

tail -n 100 /var/log/messages

好像日志还是和之前一样，这个是面板崩溃了嘛？

提交工单吧，我具体看看日志，从你的描述上看应该是系统在kill进程。

提交工单直接提交appnode面板工单是吗？

停止防火墙后，面板可访问：

至于你说的一直重启，我观察了5分钟并没有出现，要怎么让它出现？

感谢大佬。
