Java初体验

1、 将该文件放在 /etc/init.d目录下，以后就可以使用service tomcat start/stop/status/restart等命令了

2、 在/etc/rc.d/rc3.d目录下，执行 ln –s /etc/init.d/tomcat /etc/rc.d/rc3.d/S99tomcat
这样，开机就会自动启动Tomcat了。

3.如果不能运行，请检查
chmod 755 /etc/init.d/tomcat
chmod 755 apache-tomcat-5.5.25/
vi /etc/passwd
修改启动用户如
apache 的/sbin/nologin 为/bin/bash

4、 脚本
#!/bin/sh
#
# Start staff.macaufly.net webserver
# Currently installed under /home/jira and should moved to /home/tomcat later
#

TOMCAT_BIN=/home/tomcat6/bin
TOMCAT_USER=apache

sleep 10
if netstat -an | grep 8080 >/dev/null
then
echo "Tomcat is running"
return 0
else
return 1
fi
}

stop() {
if netstat -an | grep 8080 | grep LISTEN >/dev/null
then
# try to shutdown the server first
echo "Now Shutdown the server..."
su - $TOMCAT_USER -c $TOMCAT_BIN/shutdown.sh

echo "Tomcat is not running"
return 0
fi

if netstat -an | grep 8080 | grep LISTEN
then
sleep 10
echo "Now kill it"
ps -ef | grep java | grep $TOMCAT_USER | awk '{print "kill -9 ", $2;}' | sh
fi

if netstat -an | grep 8080 | grep LISTEN >/dev/null
then
return 1 # still alive
else
echo "Tomcat is stopped"
return 0
