Tomcat+Nginx动静分离

一、安装Nginx

1、安装语言包

[root@localhost ~]# yum -y install pcre-devel zlib-devel gcc gcc-c++
[root@localhost ~]# useradd -M -s /sbin/nologin nginx
[root@localhost ~]# tar zxvf nginx-1.12.2.tar.gz -C /opt

2、配置编译安装

[root@localhost ~]# cd /opt/nginx-1.12.2/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module	             //开启stub_ status状态统计模块//
[root@localhost ~]# make && make install
[root@localhost ~]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/            //让系统识别命令

3、检查、启动、重启、停止

[root@localhost ~]# nginx- t		//检查
[root@localhost ~]# nginx		//启动
[root@localhost ~]# killall -1 nginx	//重启
[root@localhost ~]# killall -3 nginx	//停止

yum install elinks -y //安装软件
elinks http://localhost //验证访问，会提示welcome语句

4、制作管理角本

[root@localhost ~]# vim /etc/init.d/nginx
#!/bin/bash
#chkconfig: - 99 20
#description: Nginx Service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
     start)
	$PROG
	;;
    stop)
	kill -s QUIT $(cat $PIDF)
	;;
    restart) 
	$0 stop
	$0 start
	;;
    reload)
	kill -s HUP $(cat $PIDF)
	;;
    *)
	echo "Usage: $0 {start |stop|restart |reload}"
	exit 1
esac
exit 0

[root@localhost ~]# chmod +x /etc/init.d/nginx
[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# chkconfig --level 35 nginx on

#访问验证

二、安装tomcat

1、设置环境

#先关闭防火墙

[root@localhost ~]# systemctl stop firewalld.service 
[root@localhost ~]# setenforce 0

#首先需要先安装jdk

[root@localhost opt]# tar zxvf jdk-8u91-linux-x64.tar.gz 

[root@localhost opt]# mv jdk1.8.0_91/ /usr/local/
[root@localhost opt]# cd /usr/local/
[root@localhost local]# ls
bin  etc  games  include  jdk1.8.0_91  lib  lib64  libexec  sbin  share  src

#设置环境变量

[root@localhost local]# vim /etc/profile         //编辑系统变量文件

#末行添加三条

export JAVA_HOME=/usr/local/jdk1.8.0_91
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$PATH
[root@localhost local]# source /etc/profile		//使环境变量生效

#验证

[root@localhost local]# java -version		//查看jdk版本（为安装的版本）

java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

2、安装并启动Tomcat

#安装包已下载，挂载并解压

[root@localhost opt]# ls
apache-tomcat-8.5.16.tar.gz  jdk-8u91-linux-x64.tar.gz  rh
[root@localhost opt]# tar zxvf apache-tomcat-8.5.16.tar.gz -C /usr/local

#切换至安装目录并进行优化

[root@localhost opt]# cd /usr/local/
[root@localhost local]# ls
apache-tomcat-8.5.16  etc    include      lib    libexec  share    bin                   games  jdk1.8.0_91  lib64  sbin     src
[root@localhost local]# mv apache-tomcat-8.5.16/ tomcat           //解压后名字太长，重命名
[root@localhost local]# ls
bin  etc  games  include  lib  lib64  libexec  nginx  sbin  share  src  tomcat
[root@localhost local]# cd tomcat/
[root@localhost tomcat]# ls
bin  conf  lib  LICENSE  logs  NOTICE  RELEASE-NOTES  RUNNING.txt  temp  webapps  work
[root@localhost tomcat]# cd bin/
[root@localhost bin]# ls

[root@localhost bin]# ln -s /usr/local/tomcat//bin/startup.sh /usr/bin/		//将开启脚本添加到/usr/bin中，自动识别
[root@localhost bin]# ln -s /usr/local/tomcat//bin/shutdown.sh /usr/bin/		//将关闭脚本添加到/usr/bin中，自动识别

#执行开启脚本

[root@localhost bin]# startup.sh
[root@localhost bin]# netstat -ntap | grep 8080

#访问验证

三、配置动静分离

实现网站动静分离，jsp页面的信息直接由tomcat进行解析处理。

1、nginx配置

[root@localhost ~]# cd /usr/local/nginx/conf/

[root@localhost conf]# vim nginx.conf

……省略内容
    server {
        listen       80;
        server_name  localhost;
        location ~.*.jsp$ {			//添加以下内容
          proxy_pass http://192.168.100.41:8080;		//jsp页面交由Tomcat处理
          proxy_set_header Host $host;
        }
……省略内容

#创建静态页面，便于验证识别

[root@localhost ~]# vim /usr/local/nginx/html/index.html

[root@localhost ~]# service nginx stop
[root@localhost ~]# service nginx start

#静态页面测试

2、Tomcat设置

#设置被访问的动态网页内容

[root@localhost ~]# mkdir /usr/local/tomcat/webapps/test
[root@localhost ~]# vim /usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.util.Date" %>
<%@ page import="java.text.SimpleDateFormat" %>







动态页面

#动态页面测试

四、nginx处理静态图片，Tomcat处理动态页面配置

• Tomcat指路径，nginx放图片
• 目录名称需要和Java项目名称相同

1、Tomcat配置

[root@localhost ~]# vim /usr/local/tomcat/webapps/test/index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.util.Date" %>
<%@ page import="java.text.SimpleDateFormat" %>







动态页面
		//添加图片

2、nginx配置

 [root@localhost ~]# vim  /usr/local/nginx/conf/nginx.conf
 ……省略内容
 server {
        listen       80;
        server_name  localhost;
        location ~.*\.(gif|jpg|jpeg|png|bmp|swf|css)$ {		//添加此段内容，匹配这些类型的文件
         root html;		//html站点目录
         expires 30d;		//缓存时间30天
		}
        charset utf-8;
        location ~.*.jsp$ {
          proxy_pass http://192.168.100.42:8080;
          proxy_set_header Host $host;
        }

……省略内容

[root@localhost ~]# mkdir /usr/local/nginx/html/test/
[root@localhost ~]# cp /opt/1.png /usr/local/nginx/html/test/
[root@localhost ~]# cd /usr/local/nginx/html/test/
[root@localhost ~]# ls
1.png

3、访问测试

动静分离，部署完成！
