Nginx + PHP-FPM no Centos 6.5 me fornece 502 Bad Gateway (erro fpm: não é possível ler o que uma criança diz: descritor de arquivo incorreto)

Question

Estou configurando uma pilha LEMP padrão. Minha configuração atual está me dando o seguinte erro:

502 Gateway inválido

Isso é o que está atualmente instalado no meu servidor:

sidenote: o nginx e o php-fpm foram configurados para serem executados em uma conta local chamada www-data e as seguintes pastas saem do servidor

Eu tenho um arquivo em /home/www-data/public_html/index.php com o código <?php phpinfo(); ?> (arquivo enviado como usuário www-data ).

    

Answer 1

nginx tmp dir não é gravável pelo usuário nginx está sendo executado como, no seu caso, "www-data"

/var/lib/nginx/tmp/fastcgi/2/00/0000000002" failed (13: Permission denied)

tente "chown -cR www-data. / var / lib / nginx"
