↑「systemctl status」コマンドで、みると、「’127.0.0.1:9000′: Address already in use」と出てきます。

↑9000ポートに関して、「TIME_WAIT」状態のソケットがたくさん起動しています。
php-fpmのプロセスを落とす
# ps ax |grep php-fpm 1021 ? Ss 0:00 php-fpm: master process (/usr/local/etc/php-fpm.conf) 1027 ? S 0:00 php-fpm: pool www 1028 ? S 0:00 php-fpm: pool www 27803 pts/0 S+ 0:00 grep --color=auto php
↑「php-fpm」に関するプロセスを確認します。
# kill -9 1021 1027 1028
↑上記、左側数字を「kill -9」コマンドで、プロセスを落とします。
# ps ax |grep php-fpm 27819 pts/0 S+ 0:00 grep --color=auto php-fpm
↑php-fpm関係のプロセスが無くなり、php-fpmが停止しました。
php-fpm再起動
