我刚刚在新的CentOS 7上安装了nginx 我的配置有这样的行:
access_log <path to log dir>/access.log;
error_log <path to log dir>/error.log error;
<path to log dir>
的所有部分拥有0777权限 Nginx无法启动:
[root@host dir]# systemctl start nginx.service
Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
[root@host dir]# systemctl status nginx.service
nginx.service - nginx - high performance web server

我能够开始的唯一方法是将<path to log dir>
更改为&#34; / tmp&#34;。当然,这不是我想要的。此外,即使nginx已经开始,日志也没有出现在/ tmp。
我做错了什么?
感谢。
UPD:
似乎selinux阻止了nginx。感谢@ 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
答案 0 :(得分:2)
在这些情况下,首先要做的是check if selinux is in enforcing mode:
[root@localhost ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 21
Policy from config file: targeted
如果是,check audit log。
