development tool _JSVC. Using JSVC to enable Tomcat to run the listening 80 port on a normal user?

Brief introduction:

Description: Jsvc is primarily used on non-Windows operating systems to run a Java server bound to a privileged port on a non-root user, a service wrapper written specifically by C, and easily combined with a shell script to write a daemon script. Run as a standalone process exists.

Quick installation:

Yum-y Install gcc autoconfcd/xm-workspace/xm-webs/xmcloud/tomcat8081/bintar-zxvf commons-daemon-native.tar.gz & & CD Commons-daemon-1.0.15-native-src/unix/bash support/buildconf.sh./configure--with-java=/xm-workspace/ XM-WEBS/XMCLOUD/JDK && make# Bin directory The default comes with daemon.sh calls is Jsvc command mv-f jsvc/xm-workspace/xm-webs/xmcloud/ TOMCAT8081/BIN/CD. /.. /&& RM-RF COMMONS-DAEMON-1.0.15-NATIVE-SRC
