1）LB层的nginx配置
访问http强制转到https
[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/80-www.kevin.com.conf
server {
listen 80;
server_name kevin.com www.kevin.com;
access_log/data/nginx/logs/www.kevin.com-access.log main;
error_log/data/nginx/logs/www.kevin.com-error.log;
error_page 500 502 503 504/50x.html;
location =/50x.html {
root html;
}
return301 https://$server_name$request_uri;
}
https反向代理的配置
[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/443-www.kevin.com.conf
