Centos7 Many of the commands have changed and have to be remembered again.
Centos7 the httpd is installed by default? Don't remember, look at:
Rpm-qa |grep httpd
If not, please install it.
Yum-y Install httpd
Yum-y Install PHP
Yum-y Install PHP-GD php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp Php-soap Curl Curl-devel
Second, start the httpd service, and set the boot to boot.
Systemctl Start Httpd.service
Systemctl Enable Httpd.service
at this point, the configuration file is linked to the/etc/systemd/system/multi-user.target.wantstpd.service, as
ll/etc/systemd/system/multi-user.target.wants/

Third, open FIREWALLD firewall port firewall-cmd--add-service=http even open firewall-cmd--permanent--add-service=http Writing the configuration file at this point, httpd This service is added to the/etc/firewalld/zones/public.xml zone configuration file, so FIREWALLD can be released accordingly. This file resembles the following:
<?xml version= "1.0" encoding= "Utf-8"?>
<zone>
<short>Public</short>
<description>for use on public areas. You don't trust the other computers in networks to not harm your computer. Only selected incoming Connections is accepted.</description>
<service name= "dhcpv6-client"/>
<service name= "http"/>
<service name= "ssh"/>
<service name= "https"/>
</zone>
be careful not to confuse the service Firewalld managed here with the Sevice hive in Systemd, which does not have any relationship.
The HTTP service is installed automatically when installing FIREWALLD, the configuration file for this service is/usrb/firewalldrvicestp.xml, let's take a look at this file.
<?xml version= "1.0" encoding= "Utf-8"?>
<service>
<short>www (HTTP) </short>
<description>http is the protocol used to serve Web pages. If you plan to make your WEB server publicly available, enable the This option. This option isn't required for viewing pages locally or developing Web pages.</description>
<port protocol= "tcp" port= "/> "
<rvice>
This means that the HTTP service corresponds to port 80 of the TCP protocol. Firewalld according to the service name HTTP in the zone configuration file, in the/etc/firwalldrvices/directory, the/usrb/firewalldrvices/directory to find the file named Http.xml, found to stop the search, so located/ The configuration file for the etc/firwalldrvices/directory has a higher precedence.
the difference between 4 and CentOS6.5
The general idea is consistent, is the firewall release, the service to join the run-level configuration file. Just CentOS7 the firewall and the run-level hypervisor are completely changed. Firewalld instead of IPTABLES,SYSTEMD instead of SYSTEMV init, so you need to be familiar with the commands again. The individual feels that the new procedure is more humane and easy to operate. The configuration file also uses the standard XML format, discarding the old, error-prone configuration file.
