1)vi phpinfo.php
www.db-hub.net:8080/phpinfo.php
显示正常
2)查看error logs
tail -50 /var/log/nginx/error.log
2020/11/07 17:00:51 [crit] 853#0: *205 open() “/var/lib/nginx/tmp/fastcgi/6/00/0000000006” failed (13: Permissi on denied) while reading upstream, client: 24.156.167.197, server: www.db-hub.net:8080, request: “GET /phpinfo.php HT TP/1.1”, upstream: “fastcgi://unix:/run/php-fpm/www.sock:”, host: “db-hub.net:8080”
发现：/var/lib/nginx owner: nginx group: root
sudo chown -R azureuser:azureuser /var/lib/nginx
sudo chmod -R 755 /var/lib/nginx
问题解决。
