LuM*_*uMa 4 nginx selinux centos
我的 CentOS 7 机器上运行着 nginx。每天我都会运行一个 cron 作业来生成新的 Diffie-Hellman 参数。它们保存在/etc/ssl/dh/dhparam.pem
. 但是 SELinux 正在阻止 nginx 读取此文件。
这是 nginx 错误日志中的一行:
nginx[3189]: nginx: [emerg] BIO_new_file("/etc/ssl/dh/dhparam.pem") failed (SSL: error:0200100D:system library:fopen:Permission denied:fopen('/etc/ssl/dh/dhparam.pem','r') error:2006D002:BIO routines:BIO_new_file:system lib)
这是审计日志:

我对 SELinux 不是很熟悉(我知道我应该学习):如何在不禁用 SELinux(或将其设置为许可)的情况下授予 nginx 访问权限?
