同求刚刚新安装的 linux contos7 为什么开启不了SELinux enable # 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 - No SELinux policy is loaded. SELINUX=enforcing # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted setenforce 1 后显示 setenforce: SELinux is disabled

这个是要重启系统的

firewalld-cmd --permanent --zone=public --add-port=5000/tcp 配置完成后 firewalld-cmd --reload 一下就可以了你在xml里面配置的时候要选择zone 我看你的zone是选择的dmz区所以你访问不到，还是用命令吧
