###
1、前提
系统介绍 系统A 域名： http://yhjmp.test.com 部署服务器：192.168.56.20
服务器名称：A-system 系统B 域名： http://yh.test.com或者http://yh.test.com/B-system【本文做了301永久跳转】 部署服务器：192.168.56.140
服务器名称：B-system 系统B附属系统 域名： http://yh.test.com/B-system-bak 部署服务器：192.168.56.140
服务器名称：B-system 需求 两套系统A、B使用统一域名 http://yhjmp.test.com
点击跳转按钮，可访问两套系统中内容，域名不变
示例：浏览器地址栏中输入yhjmp.test.com域名不变访问的内容为yh.test.com上的内容
2、B系统-前端代码
[root@B-system html]# pwd /usr/share/nginx/html [root@B-system html]# tree -L 2 . ├── B-system │ └── index.html ├── B-system-bak └── index.html [root@B-system html]# cat B-system/index.html <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <h1> B ~ 系统</h1> <button onclick="window.location.href='/A-system/index.html'" type="button" id="add">跳转A系统</button> <br /><br /> <button onclick="window.location.href='/B-system/index.html'" type="button" id="add">跳转B系统</button> <br /><br /> <button onclick="window.location.href='/B-system-bak/index.html'" type="button" id="add">跳转B系统附属系统</button> <br /><br /> [root@B-system html]# cat B-system-bak/index.html <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <h1> B ~ 系统 ~ 附属系统</h1> <button onclick="window.location.href='/A-system/index.html'" type="button" id="add">跳转A系统</button> <br /><br /> <button onclick="window.location.href='/B-system/index.html'" type="button" id="add">跳转B系统</button> <br /><br /> <button onclick="window.location.href='/B-system-bak/index.html'" type="button" id="add">跳转B系统附属系统</button> <br /><br />
3、A系统-前端代码
[root@A-system html]# pwd /usr/share/nginx/html [root@A-system html]# tree -L 2 . ├── A-system └── index.html [root@A-system html]# cat A-system/index.html <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <h1> A ~ 系统</h1> <button onclick="window.location.href='/A-system/index.html'" type="button" id="add">跳转A系统</button> <br /><br /> <button onclick="window.location.href='/B-system/index.html'" type="button" id="add">跳转B系统</button> <br /><br /> <button onclick="window.location.href='/B-system-bak/index.html'" type="button" id="add">跳转B系统附属系统</button> <br /><br />
4、B系统nginx配置
[root@B-system ~]# cat /etc/nginx/nginx.conf
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
rewrite_log on;
error_log /var/log/nginx/error.log notice;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
server_name yh.test.com;
location /B-system {
root /usr/share/nginx/html;
try_files $uri $uri/ /B-system/index.html;
index index.html index.htm;
}
location /B-system-bak{
root /usr/share/nginx/html;
try_files $uri $uri/ /B-system-bak/index.html;
index index.html index.htm;
}
location / {
rewrite ^/(.*) http://yh.test.com/B-system permanent;
}
}
}
5、A系统nginx配置
[root@A-system ~]# cat /etc/nginx/nginx.conf
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
server_name yhjmp.test.com;
location /A-system {
root /usr/share/nginx/html;
try_files $uri $uri/ /A-system/index.html;
index index.html index.htm;
}
# 域名不变访问B系统资源
location /B-system {
proxy_next_upstream error timeout http_503 http_504 http_502;
proxy_connect_timeout 500s;
proxy_read_timeout 500s;
proxy_send_timeout 500s;
# 本次测试做了本地host解析。
# 生产环境未做host解析的两套系统需注释proxy_set_header Host $host;这行代码
#【proxy_set_header Host $host;含义：会代理到本机主机名下的/B-system目录寻找资源，如果没有则报错404】
#【404报错原因：如果客户端请求头中没有携带这个头部，那么传递到后端服务器的请求也不含这个头部。 这种情况下，更好的方式是使用$host变量——它的值在请求包含“Host”请求头时为“Host”字段的值，在请求未携带“Host”请求头时为虚拟主机的主域名】
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# 重写url：(.*)括号面的.* 既是后面的$1。此location中^(.*)$：则是代表匹配url中/B-system/后面的全部内容
rewrite ^(.*)$ /$1 break; #先改写URI地址
# 反向代理地址：写上域名即可，访问时后面会自行带上/B-system/$1的url
proxy_pass http://yh.test.com;
}
location / {
rewrite ^/(.*) http://yhjmp.test.com/A-system permanent;
}
}
}
6、单独访问B系统效果(无法访问到A系统)
7、使用同一域名访问效果(访问A/B系统)
