docker启动时出现open() “/usr/local/openresty/nginx/conf/nginx.conf“ failed (13: Permission denied)

运行一下命令启动docker

docker start b2c

发现启动失败, docker logs b2c看日志,发现下面错误:

2020/07/03 16:03:06 [emerg] 1#1: open() "/usr/local/openresty/nginx/conf/nginx.conf" failed (13: Permission denied)

可是看nginx.conf的权限, 所有人都有读权限啊:

[root@anti-03 config]# ls -l
total 20
-rw-rw-rw-. 1 root root 6450 Jul  3 15:59 nginx.conf
-rw-r--r--. 1 root root 4483 Nov  2  2019 nginx.conf.all_proxy
-rwxr-xr-x. 1 root root  266 Nov  2  2019 switch_conf.sh

一番百度,发现是enforce没有关闭导致的. 可以用下面命令临时关闭

setenforce 0

如果要永久关闭,可以

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

重启机器即可
