我剛剛安裝上的CentOS新鮮7.
我的配置nginx的日誌文件中有這樣的臺詞：Nginx的不能創建
access_log <path to log dir>/access.log;
error_log <path to log dir>/error.log error;
各地<path to log dir>的具有0777的權限。
的Nginx無法啓動：
[[email protected] dir]# systemctl start nginx.service
Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
[[email protected] dir]# systemctl status nginx.service
nginx.service - nginx - high performance web server

我能夠啓動的唯一方法是，當我已經改變了<path to log dir>爲「/ tmp目錄」。當然，這不是我想要的。另外，即使nginx已經啓動，日誌也不會出現在/ tmp中。
我在做什麼錯？
謝謝。
UPD：
似乎selinux阻止nginx。感謝@ dusan.bajic

SOLUTION：
http://axilleas.me/en/blog/2013/selinux-policy-for-nginx-and-gitlab-unix-socket-in-fedora-19/
setenforce 0
yum install -y policycoreutils-{python,devel}
grep nginx /var/log/audit/audit.log | audit2allow -M nginx
semodule -i nginx.pp
setenforce 1
SEQUEL：
Nginx creates log files on behalf of root
也許'selinux'處於執行模式，audit.log中的任何內容？ –
@ dusan.bajic，看起來你是對的。我已經更新了這個問題。 – seelts
@ dusan.bajic，請發表您的評論作爲答案，以便我可以接受它 – seelts
