Nginx反向代理Tomcat服务器

一、Tomcat

基本配置

1.为Tomcat提供SysV脚本

2.catalina 脚本讲解

3.telnet 登录管理Tomcat

4.配置Tomcat虚拟主机

5.Tomcat图形管理接口

6.部署JSP网站案例

二、Nginx反向代理Tomcat服务器

1.Nginx将请求反向代理到后端Tomcat

2.Nginx将图片缓存到本地

3.Nginx将请求实现动静分离

注，实验环境说明，操作系统：CentOS 6.4 x86_64，软件版本：jdk-7u40、

apache-tomcat-7.0.42、Nginx-1.4.2，博客中所用到的软件请到这里下载：

一、Tomcat 基本配置

1.为Tomcat提供SysV脚本

注，在上一篇博文中我们已经演示安装了Tomcat，这里我们就不在演示，不清楚的博友可以参考这篇博文，/2033581/1299644，在上一篇博文中我们没有增加，SysV脚本，在这篇博文中我们来增加一下，下面我们就来具体演示一下。

[root@tomcat ~]# vim /etc/init.d/tomcat

#!/bin/sh

# Tomcat init script for Linux.

#

# chkconfig: 2345 96 14

# description: The Apache Tomcat servlet/JSP container.

CATALINA_HOME=/usr/local/tomcat #注意你的脚本路径

export CATALINA_HOME

# export CATALINA_OPTS="-Xms128m -Xmx256m"

exec $CATALINA_HOME/bin/catalina.sh $*

下面我们来增加执行权限，并加入服务列表设置开机自启动，

[root@tomcat ~]# chmod +x /etc/init.d/tomcat

[root@tomcat ~]# chkconfig --add tomcat

[root@tomcat ~]# chkconfig tomcat --list

tomcat 0:关闭1:关闭2:启用3:启用4:启用5:启用6:关闭

下面我们来启动一下Tomcat并测试一下，

[root@tomcat ~]# service tomcat start

Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp

Using JRE_HOME: /usr

Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/to mcat-juli.jar

查看一下启动的端口号，

[root@tomcat ~]# netstat -ntulp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Progra m name

tcp 0 0 :::8009 :::* LISTEN 13088/java

用浏览器访问一下，

好了，到这里Tomcat的SysV脚本增加完成，下面我们来说一下catalina脚本。

2.catalina 脚本讲解

首先我们来查看一下这个脚本，

[root@tomcat bin]# catalina.sh -h

Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp

Using JRE_HOME: /usr/java/jdk1.7.0_40

Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/to mcat-juli.jar

Usage: catalina.sh ( commands ... )

commands:

debug Start Catalina in a debugger

debug -security Debug Catalina with a security manager

jpda start Start Catalina under JPDA debugger

run Start Catalina in the current window

run -security Start in the current window with security manager

start Start Catalina in a separate window

start -security Start in a separate window with security manager

stop Stop Catalina, waiting up to 5 seconds for the process to end

stop n Stop Catalina, waiting up to n seconds for the process to end

stop -force Stop Catalina, wait up to 5 seconds and then use kill -KILL if still ru nning

stop n -force Stop Catalina, wait up to n seconds and then use kill -KILL if still r unning

configtest Run a basic syntax check on server.xml - check exit code for result version What version of tomcat are you running?

Note: Waiting for the process to end and use of the -force option require that $CA TALINA_PID is defined
