在nginx配置文件中http下添加如下配置（根据自己的实际情况修改）

upstream webman {
server 127.0.0.1:8989; //修改自己的端口号
keepalive 10240;
}

server {
server_name www.baidu(自己的域名地址).cn; //修改自己的实际域名
listen 80;
access_log off;
root /www/wwwroot/default/ling_admin/public; //修改实际项目public路径
listen 443 ssl;
ssl_certificate /etc/nginx/conf/ssl/*.cn_bundle.crt; //ssl证书.crt文件实际路径地址
ssl_certificate_key /etc/nginx/conf/ssl/.cn.key; //ssl证书.key文件实际路径地址
location ^~ / {
proxy_pass http://127.0.0.1:8989; //修改实际端口号
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Connection "";
if (!-f $request_filename){
proxy_pass http://webman;
}
}
}
