このコマンド「service httpd restart」でApacheサーバーを再起動すると、次のメッセージが表示されます。
httpd の停止: [失敗] httpd の起動: [OK]
問題が発生する前に、古いデータベース ファイルを新しいファイルに置き換えるだけで済みました。このデータベース ファイルは、別の php ファイルで使用されます。差し替え時、httpdを停止しませんでした。
Apacheサーバーの再起動に失敗した後、Webをサーフィンして解決策を見つけ、次の方法を試しました.
1) この "netstat -lnp | grep httpd" および "lsof -i:80" を試して、ポート 80 をバインドするプロセスがあるかどうかを確認します。結果は、プロセスはありません。
2) この "rm -f /var/lock/subsys/httpd" によってロックされたサブシステムを削除し、httpd を再起動しますが、結果は上記のメッセージと同じです:
Stopping httpd: [FAILED]
Starting httpd: [ OK ]
3) サーバーを再起動しても動かないようだった
この問題にどう取り組むか？
