Nginx一个server配置多个location(使用alias)

公司测试平台需要制定浏览性能测试结果。网上查到了两个办法：

在配置文件中增加多个location，每个location对应一个项目
比如使用80端口，location / 访问官网； location /report 性能测试结果
配置多个站点
我选择了配置多个location。
location / {
root /usr/local/nginx/html/dist;
index index.html index.html;
}
location /report {
root /data/sys/jmx;
index index.html index.html;
}

配置完以后访问。http://xxxx/report 提示404
找了好久才搞明白， location如果一个特定的url 要使用别名，不能用root，alias指定的目录是准确的，root是指定目录的上级目录，改动后即可以使用了

location /report {
alias /data/sys/jmx;
index index.html index.html;
}

 最后nginx.conf的配置内容如下

#user nobody;
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 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 {
