您好: 我的doris从1.2.1升级到1.2.7.1后，fe无法正常启动，启动报错内容如下： Error option /bin/bash /opt/apache-doris/fe/bin/start_fe.sh DEBUG >>>>>> FE_ID = [0] DEBUG >>>>>> FE_SERVERS = [fe1:xxx.xxx.xxx.xx:9010] DEBUG >>>>>> tmpFeId = [1] DEBUG >>>>>> tmpFeIp = [xxx.xxx.xxx.xx] DEBUG >>>>>> tmpFeEditLogPort = [9010] DEBUG >>>>>> feIpArray = xxx.xxx.xxx.xx DEBUG >>>>>> feEditLogPortArray = 9010 DEBUG >>>>>> masterFe = xxx.xxx.xxx.xx:9010 DEBUG >>>>>> currentFe = : DEBUG >>>>>> Append the configuration [priority_networks = ...0/24] to /opt/doris-fe/conf/fe.conf DEBUG >>>>>> FE is follower, fe_id = 0 DEBUG >>>>>> registerMySQL = 【mysql -uroot -P9030 -p123456 -hxxx.xxx.xxx.xx -e "alter system add follower ':'"】 DEBUG >>>>>> registerShell = 【/opt/apache-doris/fe/bin/start_fe.sh --helper 'xxx.xxx.xxx.xx:9010'】 DEBUG >>>>>> feMasterStat = 【mysql -uroot -P9030 -p123456 -h xxx.xxx.xxx.xx -e "show frontends" | grep "xxx.xxx.xxx.xx_9010" | grep -E "true[[:space:]]*true"】 Run registerShell command, [ registerMySQL = mysql -uuser -P9030 -p123456 -hxxx.xxx.xxx.xx -e "alter system add follower ':'" ] ERROR 2002 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xx' (115) ERROR 2002 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xx' (115) Run registerShell command, [ registerMySQL = mysql -uroot -P9030 -p123456 -hxxx.xxx.xxx.xx -e "alter system add follower ':'" ] ERROR 2002 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xx' (115) ERROR 2002 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xx' (115)
该问题我也上报至github中， https://github.com/apache/doris/discussions/26834 目前是生产环境遇到此问题，情况比较紧急，还请各位帮忙答疑解惑，感谢。
