location / {
        ...
        proxy_read_timeout 150;
        ...
    }

2. Nginx作为php-fpm等等其他的有上游服务

在这种情况下，适当的调整fastcgi_read_timeout选项值文章源自运维生存时间-https://www.ttlsa.com/nginx/nginx-upstream-timed-out-110-connection-timed-out/

location ~* .php$ {
    include         fastcgi_params;
    fastcgi_index   index.php;
    fastcgi_read_timeout 150;
    fastcgi_pass    127.0.0.1:9000;
    fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
