Debugging logs for linux (tomcat jsp server configuration method)

 

In order to allow others to better understand the specific operation of a command, I would like to ask all of you to take your own steps on linux
The output is written to a log file so that others can perform the same operation easily. Here I want to expand
Home provides some logs by myself.
For example, tomcat installation and configuration, jdk installation configuration, WebSphere installation configuration, and mail configuration
DNS configuration. Route modification, Nic configuration. Disk mounting, partitioning, and formatting.
File Search, Java environment configuration compilation error handling analysis. C ++ compilation error handling analysis.
Write, and lilo configurations of makefile.
Hope you have any help. If you are in trouble, you can use netterm to flip the screen.
