Linux下jdk、tomcat和apr的集成安装脚本(version2)

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

--------------------------------------------------------------

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
