cdnbest管理系统节点每隔一段时间就重启kangle进程是什么情况，log日志看到如下，原来是自动更新升级

cat /var/log/cdnbest.log | grep reboot

复制代码

通过日志可以看到每隔5个小时整跳出一次

看了下完整日志，原来是cdnbest节点会自动更新升级kangle程序，和主控无关

看了下只有节点空闲的情况下，无访问情况时，cdnbest才会执行这个操作，虽然对用户访问没影响，使用的是无感知平滑重启，访客访问不会受到中断。
但是会丢失内存缓存数据，比如说节点缓存了100G内存数据，重启后就丢失了需要重新进行内存缓存导致命中率变低。

看了下没被升级的节点跳出错误如下

Sat Jul 24 05:48:11|WLWLSL autoupdate download failed,err[exit status 1] autoupdate autoupdate2.conf is not found

复制代码

那么就好解决了，用这条命令关闭节点自动更新

mv /vhs/kangle/bin/autoupdate /vhs/kangle/bin/autoupdate.bak

复制代码

成功关闭自动升级后效果，此时kangle进程不会被重启

Sun Jul 25 10:51:11|autoupdate now...
Sun Jul 25 10:51:11| autoupdate download failed,err[fork/exec /vhs/kangle/bin/autoupdate: no such file or directory] autoupdate autoupdate2.conf is not found

哇日志中还可以看到操作的iptables，原来是cdnbest操作的，我还以为kangle能直接操作。

iptables是kangle操作的，cdnbest负责通知kangle api
