CentOS 7 無法access apache

前陣子聽到CentOS 7出了，載下來裝好發現連不到網頁
搞不清楚問題在哪，最後猜是SELinux~

# sestatus
SELinux status:                 enabled    
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

果然是開啟的
再來就來關掉selinux
改成disabled

# vi /etc/selinux/config
--
# 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=disabled
# SELINUXTYPE= can take one of these two values:
#       targeted - Targeted processes are protected,
#       mls - Multi Level Security protection.
SELINUXTYPE=targeted

再一次

# sestatus
SELinux status:                 disabled

很高興的以為抓到問題，但restart後一樣連不到... QQ
試好久，猜應該是firewall問題
果然一查CentOS 7 firewall，就找到答案了
以下截錄 關閉 CentOS 7 上的 Firewall

關閉 Firewall
# systemctl stop firewalld

預設不啟動 Firewall
# systemctl disable firewalld
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'

總於... 連的到網頁了... ya
