在linux上安装有些东西时会出现 Permission denied 的情况：以下就是解决它的办法之一 编辑/etc/selinux/config，找到这段： # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. SELINUX=enforcing
