【问题描述】:
我正在使用 Centos 7,并尝试打开端口 80 和 443。
遵循来自 centos 7 - open firewall port ,RHEL7: How to get started with Firewalld,How to open http port 80 on Redhat 7 Linux using firewall-cmd 和其他一些,我有以下内容:
[ricardo@m42srv02 ~]$ firewall-cmd --list-all
public (default, active)
interfaces: enp0s3
sources: 0.0.0.0/0
services: dhcpv6-client http https ssh
ports:
masquerade: no
forward-ports:
icmp-blocks:
rich rules:
[ricardo@m42srv02 ~]$
即使我添加端口 80/tcp 和 443/tcp 而不是添加服务,结果是一样的,从其他机器:
[root@m42srv01 ~]# nmap -T4 -sV -p 1-444 192.168.1.12
Starting Nmap 5.51 ( http://nmap.org ) at 2015-06-04 04:33 CEST

Host is up (0.017s latency).

PORT STATE SERVICE VERSION
22/tcp open ssh OpenSSH 6.6.1 (protocol 2.0)
80/tcp closed http
443/tcp closed https

Service detection performed. Please report any incorrect results at http://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 4.28 seconds
[root@m42srv01 ~]#
我尝试过添加服务和端口,使用 --permanent 选项,有无源,每次更改后总是重新加载防火墙,有时甚至重新启动 firewalld 服务,但这些端口总是关闭。
Iptables 被禁用。
