18，nginx proxy_pass 规则

location /ios/ { #这种情况，这里一定要匹配的是/ios/，不能是/ios

proxy_pass http://192.168.1.102:8090; #一定要保证192.168.1.102机器8090端口站点目录下有ios目录！否则访问会报错404！

proxy_redirect off ;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

1）

配置proxy_pass时，当在后面的url加上了/，相当于是绝对根路径，则nginx不会把location中匹配的路径部分代理走;

如果没有/，则会把匹配的路径部分也给代理走.

2) nginx配置

[root@localhost ~]# cd /etc/nginx/conf.d/

[root@localhost conf.d]# cat test.conf

server {

listen 80;

server_name localhost;

location / {

root /var/www/html;

index index.html;

}

[root@localhost conf.d]# cat /var/www/html/index.html

this is page of test!!!!

3）启动Nginx[root@localhost ~]# service nginx start     //或者使用 systemctl start nginx.service
  
4）测试访问（103.110.186.23是192.168.1.23机器的外网ip）
[root@localhost conf.d]# curl http://192.168.1.23
this is page of test!!!!
 
5) 为了方便测试，先在另一台机器192.168.1.5上部署一个8090端口的nginx，配置如下：
[root@bastion-IDC ~]# cat /usr/local/nginx/conf/vhosts/haha.confserver {
listen 8090;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
}
[root@bastion-IDC ~]# cat /var/www/html/index.html
this is 192.168.1.5
[root@bastion-IDC ~]# /usr/local/nginx/sbin/nginx -s reload
 
测试访问（103.110.186.5是192.168.1.5的外网ip）：
[root@bastion-IDC ~]# curl http://192.168.1.5:8090
this is 192.168.1.5

6)192.168.1.23作为nginx反向代理机器，nginx配置如下：

1）第一种情况：

[root@localhost conf.d]# cat test.conf

server {

listen 80;

server_name localhost;

location / {

root /var/www/html;

index index.html;

}

location /proxy/ {

proxy_pass http://192.168.1.5:8090/;

}

访问http://192.168.1.23/proxy/就会被代理到http://192.168.1.5:8090/。p匹配的proxy目录不需要存在根目录/var/www/html里面

注意，终端里如果访问http://192.168.1.23/proxy（即后面不带"/"），则会访问失败！因为proxy_pass配置的url后面加了"/"

[root@localhost conf.d]# curl http://192.168.1.23/proxy/this is 192.168.1.5
[root@localhost conf.d]# curl http://192.168.1.23/proxy
<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.10.3</center>
</body>
</html>

页面访问http://103.110.186.23/proxy的时候，会自动加上"/”（同理是由于proxy_pass配置的url后面加了"/"），并反代到http://103.110.186.5:8090的结果

7）第二种情况，proxy_pass配置的url后面不加"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location  /proxy/ {
          proxy_pass http://192.168.1.5:8090;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
那么访问http://192.168.1.23/proxy或http://192.168.1.23/proxy/，都会失败！
这样配置后，访问http://192.168.1.23/proxy/就会被反向代理到http://192.168.1.5:8090/proxy/
8）第三种情况 [root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
 
location  /proxy/ {
          proxy_pass http://192.168.1.5:8090/haha/;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
[root@localhost conf.d]# curl http://192.168.1.23/proxy/
192.168.1.5  haha-index.html
这样配置的话，访问http://103.110.186.23/proxy代理到http://192.168.1.5:8090/haha/
9)第四种情况：相对于第三种配置的url不加"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
 
location  /proxy/ {
          proxy_pass http://192.168.1.5:8090/haha;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
[root@localhost conf.d]# curl http://192.168.1.23/proxy/index.html
192.168.1.5   hahaindex.html
上面配置后，访问http://192.168.1.23/proxy/index.html就会被代理到http://192.168.1.5:8090/hahaindex.html同理，访问http://192.168.1.23/proxy/test.html就会被代理到http://192.168.1.5:8090/hahatest.html
[root@localhost conf.d]# curl http://192.168.1.23/proxy/index.html
192.168.1.5   hahaindex.html
注意，这种情况下，不能直接访问http://192.168.1.23/proxy/，后面就算是默认的index.html文件也要跟上，否则访问失败！
 
上面四种方式都是匹配的path路径后面加"/"，下面说下path路径后面不带"/"的情况：
1）第一种情况，proxy_pass后面url带"/"：
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
  
location  /proxy {
          proxy_pass http://192.168.1.5:8090/;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
2）第二种情况，proxy_pass后面url不带"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
  
location  /proxy {
          proxy_pass http://192.168.1.5:8090;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
[root@localhost conf.d]#
这样配置的话，访问http://103.110.186.23/proxy会自动加上"/”（即变成http://103.110.186.23/proxy/），代理到192.168.1.5:8090/proxy/
3）第三种情况
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
  
location  /proxy {
          proxy_pass http://192.168.1.5:8090/haha/;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
这样配置的话，访问http://103.110.186.23/proxy会自动加上"/”（即变成http://103.110.186.23/proxy/），代理到http://192.168.1.5:8090/haha/
4）第四种情况：相对于第三种配置的url不加"/"[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
  
location  /proxy {
          proxy_pass http://192.168.1.5:8090/haha;
}
}
[root@localhost conf.d]# service nginx restart
Redirecting to /bin/systemctl restart  nginx.service
这样配置的话，访问http://103.110.186.23/proxy，和第三种结果一样，同样被代理到http://192.168.1.5:8090/haha/
