在运行nginx时报错：
nginx: [emerg] duplicate location "/" in /home/wtl/PycharmProjects/djangoProject11/config.conf:51

我原来的代码为：

user  nginx;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /usr/local/nginx/conf/mime.types;
    default_type  application/octet-stream;

    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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;
        location / {
            root /usr/local/nginx/html;
            index index.html;
        }
        root   /home/wtl/PycharmProjects/djangoProject11;
        location /static {
            alias /home/wtl/PycharmProjects/djangoProject11/static;
        }
#        location / {
#            include /usr/local/nginx/conf/uwsgi_params;
#            uwsgi_pass 127.0.0.1:8889;
#        }

        location / {
                    proxy_pass http://127.0.0.1:9000;
        }
     }
}

修改后的代码为：

user  nginx;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /usr/local/nginx/conf/mime.types;
    default_type  application/octet-stream;

    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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;
        location / {
            root /usr/local/nginx/html;
            index index.html;
            proxy_pass http://127.0.0.1:9000;
        }
        root   /home/wtl/PycharmProjects/djangoProject11;
        location /static {
            alias /home/wtl/PycharmProjects/djangoProject11/static;
        }
#        location / {
#            include /usr/local/nginx/conf/uwsgi_params;
#            uwsgi_pass 127.0.0.1:8889;
#        }

#        location / {
 #                   proxy_pass http://127.0.0.1:9000;
 #       }
     }
}

因为代码中存在两个
location / {

}
即使里面的内容不一样，也要把这两个合并到一块。
不然会报错。

location / {
    root /usr/local/nginx/html;
    index index.html;
    proxy_pass http://127.0.0.1:9000;
}
root   /home/wtl/PycharmProjects/djangoProject11;
location /static {
    alias /home/wtl/PycharmProjects/djangoProject11/static;
}
location / {
            proxy_pass http://127.0.0.1:9000;
}

修改为：

location / {
    root /usr/local/nginx/html;
    index index.html;
    proxy_pass http://127.0.0.1:9000;
    proxy_pass http://127.0.0.1:9000;
}
root   /home/wtl/PycharmProjects/djangoProject11;
location /static {
    alias /home/wtl/PycharmProjects/djangoProject11/static;
}
#location / {
 #           proxy_pass http://127.0.0.1:9000;
#}

就行了。
