前些日子手痒写了个一步安装JDK+TOMCAT的脚本，感觉不是很完善，没有充分发挥TOMCAT的性能，
这次花了点时间完善下了脚本：
1. 给TOMCAT自动加上APR支持和参数调优（我的脚本中给Xmx设置了一半的物理内存，因为我的机器不全跑WEB应用，童鞋们可以在脚本中自行修改），
2. 为了脚本的通用性，垃圾收集器新生代采用并行收集器-XX:+UseParallelGC，并设置了最大期望响应时间（单位毫秒）-XX:MaxGCPauseMillis=100，打开了-XX:+UseAdaptiveSizePolicy，
JVM会根据负载自动调整新生代中Eden区和survivor区的大小，永生代Perm区貌似也会自动调整，没有去改动它，
3. 旧生代也是并行收集器-XX:+UseParallelOldGC，默认新生代占最大堆-Xmx的3/8，旧生代占5/8
4. 脚本修改了hosts文件，并打开了tomcat的jmxremote，端口是1234，你可以在客户机用jconsole远程连接tomcat服务器机监控它的运行情况，并且打开了垃圾回收日志，放在tomcat的logs目录下，名为gc.log
5. 增大tomcat上传war包的文件大小至500MB，开机会自启动tomcat。
6.增加了一个启动tomcat或强行杀tomcat进程重启的脚本
本脚本允许重复执行多次，不影响执行结果，
--------------------------------------------------------------
脚本所需环境:
Linux开发环境，基本上带gcc，make，openssh，zlib，openssl，openssl-devel就行了（测试采用 CentOS 6.4 32位）
--------------------------------------------------------------
脚本所需软件包:
ORACLE JDK7 不限版本（测试采用 jdk-7u45-linux-i586.tar.gz）
TOMCAT7 不限版本（测试采用apache-tomcat-7.0.47.tar.gz）
apr 不限版本（测试采用apr-1.4.8.tar.gz）
apr-util 不限版本（测试采用apr-util-1.5.2.tar.gz）
tips:执行脚本时，这四个软件包和脚本需放在同一目录下
--------------------------------------------------------------
本脚本完成的一些功能：
备份原/etc/profile
备份原/etc/rc.local
备份原/etc/hosts
安装JDK
把JDK环境变量写入/etc/profile
安装tomcat
安装apr
安装apr-util
安装tomcat-native.tar.gz
把tomcat环境变量写入/etc/profile
把APR LD_LIBRARY_PATH环境变量写入/etc/profile
把tomcat自启动命令写入/etc/rc.local
给tomcat添加一个管理员，账号:tomcat；密码:tomcat
在tomcat的/bin/catalina.sh加上启动参数”CATALINA_OPTS······”
增大tomcat上传war包的文件大小至500MB（这大小总该够了）
执行完脚本后，手工执行一遍source /etc/profile让新环境变量生效
