Permission refusée (échec de la création du pid) lors du démarrage de SphinxSearch

Lorsque j'essaie de démarrer le service SphinxSearch comme ceci

/etc/init.d/sphinxsearch start

ou ceci

sudo /etc/init.d/sphinxsearch start

J'obtiens l'erreur suivante

Notez que : il y avait un répertoire sphinxsearch vide, j'ai changé les permissions pour l'utilisateur sphinxsearch et changé le chemin PID dans sphinx, comme ça il est capable d'écrire un fichier PID, mais il est censé être dans /var/run

Quelqu'un sait-il comment résoudre ce problème ?
