然后复制 --prefix后面的

# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_image_filter_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --add-module=/usr/local/nginx/echo-nginx-module-0.61/ --add-modure=/usr/local/nginx/sbin/nginx

增加模块是这样的步骤
那么升级也是这个步骤

        location / {
            root   html;
            echo   'A';
            index  index.html index.htm;
        }
                location = /abc {
            echo 'B';
            root html;
            index index.html;
        }

# nginx -s reload //刷新配置文件

//然后另外开启一个终端
# curl http://192.168.99.128/abcd
A
# curl http://192.168.99.128/ab
A
# curl http://192.168.99.128/abc
B
# curl http://192.168.99.128/abcd
A
