nginx 与 php-fpm socket 所有者权限问题

Question

配置完 ngix + php-fpm 后 nginx 报错：

2014/12/08 12:19:19 [crit] 27575#0: *4 connect() to unix:/var/run/php-fpm/vbox.dev.sock failed (13: Permission denied) while connecting to upstream, client: 192.168.56.101, server: vbox.dev, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/vbox.dev.sock:", host: "vbox.dev"

相关配置如下：

php-fpm：

[vbox.dev]

user = nginx
group = nginx

listen = /var/run/php-fpm/vbox.dev.sock

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

pm = dynamic
pm.max_children = 75
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 20
pm.max_requests = 500

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

文件权限：

求指点！

Answer 1

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

以上 listen.owner listen.group 可不设定
listen.mode = 0666

另外建议sock文件放在/dev/shm目录下
此目录下将sock文件放在内存里面，有助于性能提升

Answer 2

Permission denied ...

在没有权限呀！

在root下执行。

Answer 3

你问题解决了么?没解决的话能让我看下你/var/run/php-fpm这个目录的权限么

Answer 4

原理就是你要看一下你nginx运行的用户（nginx配置文件中去看）要和php-fpm运行的用户一样（www.conf去看），一般报没有权限都是用户不一致导致的，因为php-fpm是有nginx去执行的，所以要以nginx运行的用户去运行php-fpm才有权限。
