本文介绍了一个用于启动并配置web应用的小型Shell安装脚本。该脚本能够设置防火墙端口、停止旧服务、复制配置文件，并启动新的服务。

之前做了一个功能（也是一个比较小的web应用），因为涉及到启动时可以添加一些配置，所以自己有写了个shell安装脚本。在这里简单记录一下：

#!/bin/bash

#Default install location is "/usr/local/phonebook". If you want to change install location, modify two paths: working directory below, and jar start path in start.sh

#enable 9993 port
#判断public.xml中是否已经enable9993端口，若无则在指定位置添加。注意转义字符
function enableFirewalld(){
	insertText="<description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.<\/description>"
	portText="  <port protocol=\"tcp\" port=\"9993\"\/>"
	publicXmlPath="/etc/firewalld/zones/public.xml"

	grep "9993" $publicXmlPath > /dev/null
	if [ $? -eq 0 ]; then
		echo -e "\nINFO: port 9993 has already enabled\n"
	else
		sed -i "/$insertText/a\\$portText" $publicXmlPath
		echo -e "\nINFO: enable phonebook port 9993 success\n"
	fi

	if ps -ef|grep "firewalld"|egrep -v grep >/dev/null
	then
		firewall-cmd --reload
		echo -e "\nINFO: restart firewalld success\n"
	fi
}

enableFirewalld

#该方法没有用到，这里仅是记录一下
function enableFirewalld2(){
	phoneBookPort=9993
	isFirewalldOpen=false
	isPortOpen=false
	while ( ! $isFirewalldOpen || ! $isPortOpen )
	do 
		if ps -ef|grep "firewalld"|egrep -v grep >/dev/null
		then
			isFirewalldOpen=true
			echo -e "\nINFO: start firewalld success\n"
			res=`firewall-cmd --zone=public --query-port=$phoneBookPort/tcp`
			if [ $res == "no" ]; then
				`firewall-cmd --zone=public --add-port=$phoneBookPort/tcp --permanent`
				`firewall-cmd --reload`
				enableFirewalld
			else
				isPortOpen=true
				echo -e "\nINFO: enable phonebook port 9993 success\n"
			fi
		else
			`systemctl start firewalld`
			enableFirewalld
		fi
	done
}

# stop old phonebook if exist
if ps -ef|grep "phonebook"|egrep -v grep >/dev/null
then
	`systemctl stop phonebook.service`
	echo -e "\nINFO: stop old phonebook.service success\n"
fi
