Nginx で「502 Bad Gateway」とか、なんだかエラーログがでるよって時

Last updated at Posted at 2016-04-02

皆大好きNginx

たまーに起動してやろうかと思ったら、
画面には見事に
「502 Bad Gateway」
...はまった Orz

ログを見ると、こんな感じで、Permissionエラー

$ tail -f /var/log/nginx/error.log

*1 connect() to unix:/var/run/php-fpm/php-fpm.sock failed (13: Permission denied) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm.sock:", host: "xxx.xxx.xxx.xxx"

一応確認したら、rootユーザで起動されてました。。。(ログは嘘つかないw

$ ls -l /var/run/php-fpm/php-fpm.sock
srw-rw---- 1 root root 0 /var/run/php-fpm/php-fpm.sock

どうやら、php-fpmのlisten.ownerと、listen.groupを、
nginxユーザに合わせると良いらしいです。

$ vi /etc/php-fpm.d/www.conf

listen.owner = nginx
listen.group = nginx

nginx + php-fpm のユーザを合わせる。
基本ですね。

失礼しました。。。TT
