Ubuntu 18.04 で、php-fpm + nginx 環境構築（バージョンアップして、Nginxが動かなくなったので対応。。）
Ubuntu 12.04 → 13 → 16 → 17 → 18 までアップデートしたら、
設定ファイルが色々変わりすぎていて、
nginxが起動しなくなりました。
まずは、php-fpmをアップデート。

php-pfmのパスを更新。
root@hostname:/etc/nginx# ll /var/run/php/php7.2-fpm.sock srw-rw---- 1 www-data www-data 0 May 14 01:08 /var/run/php/php7.2-fpm.sock= root@hostname:/etc/nginx# vi /etc/nginx/nginx.conf 58 upstream php { 59 #server unix:/var/run/php-fpm/php-fpm.sock; 60 server unix:/var/run/php/php7.2-fpm.sock; 61 }
listenソケットの確認（パスを合わせる）と、
Webサーバのユーザ諸々をwww-dataから、nginxに更新。
root@hostname:/etc/nginx# vi /etc/php/7.2/fpm/pool.d/www.conf listen = /var/run/php/php7.2-fpm.sock user = nginx group = nginx listen.owner = nginx listen.group = nginx
nginxでphpを使えるように設定する。
index.phpを追加。
バーチャルホストがある場合は、バーチャルホストのserver設定も確認する。
→WordPressサイトのトップURL（http://バーチャルホストドメイン/）が403で、あれれとなったので・・・。
root@hostname:/etc/nginx# vi /etc/nginx/sites-available/default

64 }
php-fpmとnginxの再起動。
