linux 多jetty启动脚本

这个脚本是通过命令的方式来启动不同的jetty

假设这个文件名为jetty-root.sh 放在/home/chris 下 我们可以通过ln命令设置快捷方式jj

ln -s /home/chris/jetty-root.sh /usr/bin/jj

/data/app/jetty-chris 的启动命令为 jj start chris  停止命令为 jj stop chris  查看日志jj logf chris

/data/app/jetty-hudson 的启动命令为 jj start hudson 停止命令为 jj stop hudson  查看日志jj logf hudson

#!/bin/bash

ME=`basename $0`
ArgCount=$#
# 启动命令 stop | start | log | logn | logf
CMD=$1
# 启动jetty的唯一标识 目录如果为jetty-chris则启动这个jetty 使用  start chris
KEY=$2
NOWDAY=`date +%Y`_`date +%m`_`date +%d`
WHO=`whoami`

if [ ! $ArgCount -eq 2 ]; then
echo "    Arg count must be 2"

echo "        log is cat log file"
echo "        logn is tail log file last 1000 line"
echo "        logf is tail -f log file"

#要同时启动多个jetty 要修改对应jetty.xml的端口 避免出现端口相同的情况
