if a health check exists on port 8091 ?

if a health check exists on port 8091 ?

Because port 9091 is occupied by another application, I running the following command the start the seata server.
./seata-server.sh -h 10.132.102.141 -p 9092 -m db

I run the netstat command the check the port 8091. It seem this port is ok, this port is occupied by seata application.
netstat -tunlp | grep 8091
tcp6 0 0 :::8091 :::* LISTEN 123042/java

if a health check exists on port 8091 ?

In application.yml, I set the port as 8091 rather than the default value 7091. because the port 8091 is occupied by another application and execute the following command to restart the seata server.

./seata-server.sh -h 10.132.102.141 -p 9092 -m db

@slievrly ,

following is the config info which is stored in the apollo. Is there any additional infomation you want to know?

It appears that you accessed port 9092 using a non seata-spring-boot-starter (seata-all) SDK.

It appears that you accessed port 9092 using a non seata-spring-boot-starter (seata-all) SDK.

But, I just start the seata server and find the error log. And the seata clients are not started yet.

Actually, I deploy the seata server and seata client on the same VM.

I will try to kill all the seata clients and restart the seata server to check if the ERROR log will continue.

@slievrly , I deploy the seata server and client on the same VM. And I am sure nobody know the 9092 of the seata server. I kill all the java application and restart the seata server. I reproduce the error log. Could you kindly take a look at it? thanks,

1. I kill all the java application. and run ps -ef to check
   [root@jt-ecif-mkr-051 bin]# ps -ef |grep java
   root 49953 49271 0 10:52 pts/0 00:00:00 grep --color=auto java
2. run the following command to restart seata server.
   ./seata-server.sh -h 10.132.102.141 -p 9092 -m db
3. check only seata server is running.

Check if you are accessing port 9092 using something other than the Seata SDK, such as telnet, http, etc.

检查下是否你使用非Seata SDK的方式 访问 了9092端口，比如telnet，http等方式。

应该没有。因为整个虚拟机都刚重启。
后面我会试着抓包确认一下。
