centos7 nginx location 配置

nginx 安装

yum install -y epel-release

yum –y install nginx

systemctl start nginx

systemctl enable nginx

 /etc/nginx.conf   在http节点下面添加 map  并注释掉  默认监听的80端口

参考 https://docs.microsoft.com/en-us/aspnet/core/signalr/scale?view=aspnetcore-6.0#linux-with-nginx

location编辑及解释

在nginx中配置proxy_pass代理转发时，如果在proxy_pass后面的url加/，表示绝对根路径；如果没有/，表示相对路径，把匹配的路径部分也给代理走。

假设下面四种情况分别用 http://192.168.1.1/proxy/test.html 进行访问。

第一种：
location /proxy/ {
proxy_pass http://127.0.0.1/;
}
代理到URL：http://127.0.0.1/test.html

第二种（相对于第一种，最后少一个 / ）
location /proxy/ {
proxy_pass http://127.0.0.1;
}
代理到URL：http://127.0.0.1/proxy/test.html

第三种：
location /proxy/ {
proxy_pass http://127.0.0.1/aaa/;
}
代理到URL：http://127.0.0.1/aaa/test.html

第四种（相对于第三种，最后少一个 / ）
location /proxy/ {
proxy_pass http://127.0.0.1/aaa;
}
代理到URL：http://127.0.0.1/aaatest.html
