Tomcat does not start with root privileges.

Last night the server did not start, first to restore the crime scene,

error Operation procedure : Replace a directory under the classes directory, such as COM, because of the replacement of the classes file, you need to restart Tomcat, in the bin directory to execute SH start.sh

However, you should first stop the existing process, Ps-ef |grep Java, isolate the existing process number, and then execute the KILL-9 + process number

Kill, then execute SH start.sh start failed, switch to root, start, or fail!

solve the process : replace the original directory, with the root, when it was cut into root, did not find, look at the COM directory user rights, really is root, change the permissions it chown-r Nginx.nginx, all Nginx permissions, and then execute SH start.sh, what's going on? Or can not start, Yun-dimensional brother, help it, soon, OK, what's the matter? What's going on? Brother Yun looked at Start.sh's script.

User choose the wrong, forget to say, the current use is SA user, Su nginx,sh start.sh,ps-ef |grep java good, start success!

The next time you replace the file, you must pay attention to the user! Be careful with root!.
