nginx 重启后 1 分钟内出现 502 bad gateway

nginx 重启后 1 分钟内出现 502 bad gateway

一切都运行正常，直到我将 PHP 更新到 7.2

服务器重启后一分钟内 nginx 抛出 502 错误。

Nginx 错误日志指出如果监听unix:/var/run/php/php7.2-fpm.sock：

[crit] 671#671: *2 connect() to unix:/var/run/php/php7.2-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 123.123.123.123, server: mysite.domain, request: "POST /provider.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.2-fpm.sock:", host: "mysite.domain", referrer: "http://mysite.domain/"

并说

[error] 667#667: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 123.123.123.123, server: mysite.domain, request: "POST /provider.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "mysite.domain", referrer: "http://mysite.domain/"

如果听127.0.0.1:9000

无论如何，一分钟后 nginx 开始按预期工作。

好像 php7.2-fpm 启动太慢了。

有人知道发生了什么事吗？服务应该在几秒内重启，而不是几分钟。

我想并执行了您的网站，页面显示了 502 bad gateway 消息。这对我有帮助：

 - Edit /etc/php5/fpm/pool.d/www.conf
 - Change listen = /var/run/php5-fpm.sock to listen = 127.0.0.1:9000
 - Ensure the location is set properly in nginx.conf.

location ~ \.php$ {
  fastcgi_split_path_info ^(.+\.php)(/.+)$;
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_index index.php;
  include fastcgi_params;
}
 - Run sudo service php5-fpm restart

所以也许它会对你有帮助。
