首先我上线时可以http访问也可以https访问，那么配置如下：
nginx.conf

user root;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

Load dynamic modules. See /usr/share/nginx/README.dynamic.

include /usr/share/nginx/modules/*.conf;

events {
worker_connections 1024;
}

http {
log_format main '$remote_addr - r e m o t e u s e r [ remote_user [remoteu​ser[time_local] “KaTeX parse error: Double superscript at position 34: … '̲status b o d y b y t e s s e n t " body_bytes_sent "bodyb​ytess​ent"http_referer” ’
