1.单机反向代理:
实验 :7-3 做客户机,7-2做代理服务器,7-1 tomcat 服务器 数据传输从7-3到7-2到7-1
配置:
7-1为之前的虚拟机配置
7-2做代理服务器配置:
7-3客户机配置:
测试:
2.反向代理多机:
静态资源nginx自己响应,动态资源转交给tomcat响应
实验:Nginx要开启upstream(负载均衡)、location(url链接)、proxy_pass(反向代理)
配置:7-1做nginx代理服务器;7-2和 7-3做Tomcat服务器
配置:
7-1安装nginx;7-3 和 7-2安装Tomcat;都开启服务!
配置7-1Nginx服务器:
bash
vim /etc/nginx/conf/nginx.conf
17 http {
18 upstream tomcat {
19 server 192.168.91.4:8080;
20 server 192.168.91.5:8080;
21 }
48 location ~* \.(jpg|png)$ {
49 root /data/html;
50 }
51
52 location / {
53 proxy_pass http://tomcat;
54 }
建立静态资源存放在本机中
配置7-2Tomcat服务器:
bash
[root@localhost ~]# cd /usr/local/tomcat/webapps/ROOT
[root@localhost ROOT]#
[root@localhost ROOT]# ls
asf-logo-wide.svg bg-upper.png tomcat.css tomcat.svg
bg-button.png favicon.ico tomcat.gif WEB-INF
bg-middle.png index.jsp tomcat.png
bg-nav.png RELEASE-NOTES.txt tomcat-power.gif
[root@localhost ROOT]#
[root@localhost ROOT]# vim test.jsp
[root@localhost ROOT]# cat test.jsp
7-2
[root@localhost ROOT]#
配置7-3Tomcat服务器 :
bash
[root@centos1 ~]# cd /usr/local/tomcat/webapps/ROOT
[root@centos1 ROOT]# ls
asf-logo-wide.svg bg-upper.png tomcat.css tomcat.svg
bg-button.png favicon.ico tomcat.gif WEB-INF
bg-middle.png index.jsp tomcat.png
bg-nav.png RELEASE-NOTES.txt tomcat-power.gif
[root@centos1 ROOT]# vim test.jsp
[root@centos1 ROOT]# cat test.jsp
7-1
[root@centos1 ROOT]#
测试:
3.反向代理多机多级:
实验:7-3为Nginx代理服务器;7-4和7-5为Nginx服务器;7-1和7-2为Tomcat服务器
配置:7-1:192.168.91.3
7-2:192.168.91.4
7-3:192.168.91.5
7-4:192.168.91.7
7-5:192.168.91.8
第一层:
7-3Nginx代理服务器传内容给7-4和7-5Nginx服务器
配置:
配置7-3Nginx代理服务器:
bash
vim /etc/nginx/nginx.conf
17 http {
18 upstream web {
19 server 192.168.91.7;
20 server 192.168.91.8;
21 }
48 location / {
49 proxy_pass http://web;
50 }
51
配置7-4Nginx服务器:
bash
[root@centos4 ~]# vim /usr/share/nginx/html/index.html
[root@centos4 ~]#
[root@centos4 ~]# cat /usr/share/nginx/html/index.html
7-4
[root@centos4 ~]#
配置7-5Nginx服务器:
bash
[root@centos5 ~]# vim /usr/share/nginx/html/index.html
[root@centos5 ~]# cat /usr/share/nginx/html/index.html
7-5
[root@centos5 ~]#
测试:
bash
[root@localhost ~]# curl 192.168.91.5
7-4
[root@localhost ~]# curl 192.168.91.5
7-5
[root@localhost ~]# curl 192.168.91.5
7-4
[root@localhost ~]#
第二层:
7-4和7-5Nginx服务器传内容给7-1和7-2Tomcat服务器
配置:
配置7-4Nginx服务器:
bash
vim /etc/nginx/nginx.conf
29 upstream tomcat {
30 server 192.168.91.3:8080;
31 server 192.168.91.4:8080;
32 }
48 location ~* \.jsp$ {
49 proxy_pass http://tomcat;
50 }
51
52 location ~* \.html$ {
53 root /usr/share/nginx/html;
54 }
配置7-5Nginx服务器:
bash
vim /etc/nginx/nginx.conf
30 upstream tomcat {
31 server 192.168.91.3:8080;
32 server 192.168.91.4:8080;
33 }
49 location ~* \.jsp$ {
50 proxy_pass http://tomcat;
51 }
52
53 location ~* \.html$ {
54 root /usr/share/nginx/html;
55 }
测试:
curl访问,验证第二层配置(7-3Nginx代理服务器 传内容给 7-4和7-5Nginx服务器;再给到7-1和7-2Tomcat服务器
当访问静态资源(.html)时:
bash
[root@localhost ~]# curl 192.168.91.5/index.html
7-5
[root@localhost ~]# curl 192.168.91.5/index.html
7-4
[root@localhost ~]# curl 192.168.91.5/index.html
7-5
[root@localhost ~]#
当访问动态资源(.jsp)时:
bash
[root@localhost ~]# curl 192.168.91.5/test.jsp
7-1
[root@localhost ~]# curl 192.168.91.5/test.jsp
7-1
[root@localhost ~]# curl 192.168.91.5/test.jsp
