实验环境

Nginx服务器(192.168.13.177)
Tomcat1服务器(192.168.13.151)
Tomcat2服务器 (192.168.13.178)
client测试机

一,负载均衡

1,在Tomcat1,Tomcat2上安装Tomcat服务

[root@tomcat1 ~]# systemctl stop firewalld.service  ##关闭防火墙
[root@tomcat1 ~]# mkdir /abc
[root@tomcat1 ~]# mount.cifs //192.168.100.3/LNMP-C7 /abc/
[root@tomcat1 ~]# cd /abc/tomcat/
[root@tomcat1 tomcat]# tar zxvf jdk-8u91-linux-x64.tar.gz -C /usr/local/  ##解压JDK
[root@tomcat1 tomcat]# vim /etc/profile   ##配置环境变量
##大G末行加入
export JAVA_HOME=/usr/local/jdk1.8.0_91
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
[root@tomcat1 tomcat]# source /etc/profile  ##刷新配置文件
[root@tomcat1 tomcat]# tar zxvf apache-tomcat-8.5.16.tar.gz -C /usr/local/   ##解压
[root@tomcat1 tomcat]# cd /usr/local/
[root@tomcat1 local]# mv apache-tomcat-8.5.16/ tomcat
[root@tomcat1 local]# ln -s /usr/local/tomcat/bin/startup.sh /usr/local/bin/  

将启动和关闭脚本便于系统识别

[root@tomcat1 local]# ln -s /usr/local/tomcat/bin/shutdown.sh /usr/local/bin/
[root@tomcat1 local]# mkdir -p /web/webapp1  ##创建站点
[root@tomcat1 local]# vim /web/webapp1/index.jsp   ##写入jsp网页内容
##jsp网页内容
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
 <head>
    <title>JSP test1 page</title>
 </head>
 <body>
    <% out.println("Welcome KGC Web");%>    ##输出信息
 </body>
</html>
[root@tomcat1 local]# vim /usr/local/tomcat/conf/server.xml  ##修改Tomcat配置文件
            <Host name="localhost"  appBase="webapps"
                        unpackWARs="true" autoDeploy="true">
                <Context docBase="/web/webapp1" path="" reloadable="false">  ##添加站点信息
                </Context>
[root@tomcat1 ~]# startup.sh   ##启动服务
## Tomcat上网页内容为accp其他配置一样

2,在Nginx服务器上安装Nginx

[root@nginx ~]# systemctl stop firewalld.service    ##关闭防火墙
[root@nginx ~]# setenforce 0
[root@nginx ~]# yum install pcre-devel zlib-devel gcc gcc-c++ make -y  ##安装环境必要组件
[root@nginx ~]# mkdir /abc
[root@nginx ~]# mount.cifs //192.168.100.3/LNMP-C7 /abc/   ##挂载
Password for root@//192.168.100.3/LNMP-C7:  
[root@nginx ~]# cd /abc/
[root@nginx abc]# tar zxvf nginx-1.12.2.tar.gz -C /usr/local/  ##解压
[root@nginx abc]# useradd -M -s /sbin/nologin nginx   ##创建系统用户
[root@nginx abc]# cd /usr/local/nginx-1.12.2/
[root@nginx nginx-1.12.2]# ./configure \   ##配置
> --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_stub_status_module \
> --with-http_gzip_static_module \
> --with-http_flv_module 
[root@nginx nginx-1.12.2]# make && make install   ##编译安装 

3,修改Nginx配置文件

[root@nginx nginx-1.12.2]# vim /usr/local/nginx/conf/nginx.conf
 #keepalive_timeout  0;
        keepalive_timeout  65;

        #gzip  on;

        upstream tomcat-server {                             #添加地址池
                            server 192.168.13.151:8080 weight=1;
                            server 192.168.13.178:8080 weight=1;    
                        }

        server {
                listen       80;
.....省略
location / {
                        root   html;
                        index  index.html index.htm;
                        proxy_pass http://tomcat-server;         #添加代理,调用服务器地址池
                }
[root@nginx nginx-1.12.2]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/  ##便于系统识别
[root@nginx nginx-1.12.2]# nginx   ##开启服务

二,动静分离

1,在Nginx上修改配置文件

[root@nginx nginx-1.12.2]# vim /etc/init.d/nginx  ##编写service启动脚本
#!/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: $0 {start|stop|restart|reload}"
                exit 1
esac
exit 0
[root@nginx nginx-1.12.2]# chmod +x /etc/init.d/nginx 
[root@nginx nginx-1.12.2]# chkconfig --add nginx
[root@nginx nginx-1.12.2]# vim /usr/local/nginx/conf/nginx.conf
server {
...省略...
     location ~.*.jsp$ {       ##匹配jsp页面跳转代理服务器池
         proxy_pass http://tomcat-server;
         proxy_set_header Host $host;
     }
            location / {
        root   html/test;   ##修改站点
        index  index.html index.htm;
        proxy_pass http://tomcat-server;
     }
[root@nginx nginx-1.12.2]# vim /usr/local/nginx/html/index.html   ##编写静态网页
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>静态页面</title>
<style>
body {
    width: 35em;
    margin: 0 auto;
    font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
    <h2>静态页面</h2>
    <p>这是个静态页面</p>
</body>
</html>
[root@nginx nginx-1.12.2]# service nginx stop    ##关闭开启服务
[root@nginx nginx-1.12.2]# service nginx start

2,在Tomcat1,Tomcat2上创建jsp动态页面

[root@tomcat1 ~]# mkdir /usr/local/tomcat/webapps/test
[root@tomcat1 ~]# vim /usr/local/tomcat/webapps/test/index.jsp
<!DOCTYPE html>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import="java.util.Date" %>
<%@ page import="java.text.SimpleDateFormat" %>   ##开头申明
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/ html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>动态页面</title>
</head>
<body>
<div>动态页面1</div>
</body>
</html>

在Tomcat2上修改为动态页面22

//访问静态
http://192.168.13.177/  
//访问动态  
http://192.168.13.177/test/index.jsp

Nginx处理静态图片,Tomcat处理动态页面
1,在Tomcat1,Tomcat2上页面添加图片

[root@tomcat1 ~]# vim /usr/local/tomcat/webapps/test/index.jsp
<body>
    <div>动态页面</div><br><img src="11.jpg"> //添加页面图片 
</body>
[root@tomcat01 local]# vim /usr/local/tomcat/conf/server.xml 
#在第149行下追加以下条目,
<Context docBase="/usr/local/tomcat/webapps/test" path="" reloadable="false">
</Context>
[root@tomcat1 test]# shutdown.sh    ##关闭重启
[root@tomcat1 test]# startup.sh

2,在Nginx上修改配置文件

[root@nginx nginx-1.12.2]# vim /usr/local/nginx/conf/nginx.conf
location ~.*\.(gif|jpg|jpeg|png|bmp|swf|css)$ { 
     root html/test;
     expires 30d;
}
[root@nginx nginx-1.12.2]# mkdir /usr/local/nginx/html/test
[root@nginx nginx-1.12.2]# cp /abc/11.jpg /usr/local/nginx/html/test/
#重启服务

3,使用client测试

[root@nginx html]# service nginx restart
