3表示主版本号,有结构性变化才更改;10表示次版本号,新增功能才变化,一般奇数表示测试版,偶数表示开发板

0表示对版本的修订次数或者补丁包数;514代表编译的次数,每次编译可对少数程序优化或修改;el7用来表示版本的特殊信息,有较大的随意性;

x86_64表示64位.

#开启防火墙

systemctl restart firewalld

当然,没有的话需要安装一下

yum install firewall

[root@VM_0_8_centos local]# firewall-cmd --permanent --zone=public  --add-service=http

success

[root@VM_0_8_centos local]# firewall-cmd --permanent --zone=public  --add-service=https

success

设置开机启动

systemctl enable firewalld

关闭防火墙

systemctl stop firewalld

取消开启启动

systemctl disable firewalld

查看状态

firewall-cmd --state

还有别的请查看帮助

firewall-cmd --help

最后所有的就绪后重新加载下

[root@VM_0_8_centos local]# firewall-cmd --reload

success

#确认80端口监听中

netstat -tulp

netstat -pan|grep 8080  查看8080端口被哪个进程所占用

netstat -aux|grep 2222 看到该端口被2222这个id的进程占用后,可以继续查看到底是什么程序占用的
