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
2）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/
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
[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/
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
[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
