Tomcat started successfully but could not open server.com:8080

1 xiaozhangzaici.com tomcat started successfully, but server.com:8080 < tomcat > 2 could not be opened. The error is "the response time of xiaozhangzaici.com is too long." , ERR_CONNECTION_TIMED_OUT .
3, you can open xiaozhangzaici.com:8080 to debug. This is my website.

problem reappears:
I thought there was something wrong with my server configuration.

later, I reinstalled the system, and then downloaded tomcat from the official website with the brand new system
1,
1, and unzipped it.
3jinsh startup.sh

visit server.com:8080. This problem occurs.

there is a clue that tomcat starts up and says, Using JRE_HOME: / usr, this is not correct, but I changed it to correct, and it didn"t work.

excuse me, prawns, where did I go wrong?

1. Check whether the firewall opens port 8080
check with the telnet port of other machines to see if you can get through
2. Check whether there is any error in the tomcat startup log


1 Firewall check
2 if it is a CVM, the security group will see if it is configured. If not, configure a tcp 8080 inbound rule
