1.6Apache2.4与php结合
1.6 Apache2.4与php结合 httpd主配置文件/usr/local/apache2.4/conf/httpd.conf vim /usr/local/apache2.4/conf/httpd.conf //修改以下4个地方
ServerName
Require all denied
AddType application/x-httpd-php .php
DirectoryIndex index.html index.php /usr/local/apache2.4/bin/apachectl -t //测试语法 /usr/local/apache2.4/bin/apachectl start //启动服务
netstat -lntp
curl localhost vim /usr/local/apache2.4/htodcs/test.php //增加如下内容
curl localhost/test.php
要想实现php的效果先编辑Apache测试文件！
[root@Dasoncheng ~]# vim /usr/local/apache2.4/conf/httpd.conf …… ServerName www.app.com ……
这里插入Linux防火墙知识：
selinux //临时关闭 setenforce 0
selinux //永久关闭 vi /etc/selinux/config
centos7之前使用netfilter防火墙、
centos7开始使用firewalld防火墙
关闭firewalld开启netfilter方法:
systemctl stop firewalld
systemctl disable firewalld
yum install -y iptables-services
systemctl enable iptables
systemctl start iptables
##关于selinux： ##临时关闭： [root@Dasoncheng ~]# getenforce Enforcing [root@Dasoncheng ~]# setenforce 0 [root@Dasoncheng ~]# getenforce Permissive ##永久关闭： [root@Dasoncheng ~]# vim /etc/selinux/config [root@Dasoncheng ~]# grep -B2 -w \'^SELINUX\' /etc/selinux/config # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled
##关于关闭firewalld开启netfilter： [root@Dasoncheng ~]# systemctl stop firewalld [root@Dasoncheng ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service. [root@Dasoncheng ~]# yum install -y iptables-services [root@Dasoncheng ~]# systemctl enable iptables.service Created symlink from /etc/systemd/system/basic.target.wants/iptables.service to /usr/lib/systemd/system/iptables.service. [root@Dasoncheng ~]# systemctl start iptables.service [root@Dasoncheng ~]# iptables -F [root@Dasoncheng ~]# iptables -nvL Chain INPUT (policy ACCEPT 6 packets, 428 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 4 packets, 448 bytes) pkts bytes target prot opt in out source destination [root@Dasoncheng ~]# service iptables save iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
编辑好了httpd.conf之后，测试：
[root@Dasoncheng ~]# /usr/local/apache2.4/bin/apachectl -t Syntax OK [root@Dasoncheng ~]# /usr/local/apache2.4/bin/apachectl graceful [root@Dasoncheng ~]# ps aux |grep httpd daemon 22383 0.1 0.9 540344 9520 ? Sl 10:13 0:00 /usr/local/apache2.4/bin/httpd -k start daemon 22384 0.1 0.9 540344 9512 ? Sl 10:13 0:00 /usr/local/apache2.4/bin/httpd -k start daemon 22386 0.1 0.9 540344 9508 ? Sl 10:13 0:00 /usr/local/apache2.4/bin/httpd -k start root 22468 0.0 0.0 112664 968 pts/0 S+ 10:13 0:00 grep --color=auto httpd root 34165 0.0 1.2 253516 12792 ? Ss 03:56 0:02 /usr/local/apache2.4/bin/httpd -k start [root@Dasoncheng ~]# netstat -lntp |grep httpd tcp6 0 0 :::80 :::* LISTEN 22383/httpd [root@Dasoncheng ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT 访问测试：
如果无法访问，从selinux、防火墙、端口等进行排查！
[root@Dasoncheng ~]# curl localhost
It works!
1.7 Apache默认虚拟主机先编辑wins的hosts文件：
域名访问：
[root@Dasoncheng ~]# vim /usr/local/apache2.4/conf/httpd.conf ##编辑主配置文件，开启虚拟主机（开启之后，原站点就会失效！） [root@Dasoncheng ~]# grep -A1 \'Virtual hosts\' /usr/local/apache2.4/conf/httpd.conf # Virtual hosts Include conf/extra/httpd-vhosts.conf 编辑虚拟主机配置文件：
[root@Dasoncheng ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for all requests that do not # match a ServerName or ServerAlias in any
[root@Dasoncheng ~]# mkdir -p /data/wwwroot/abc.com/ [root@Dasoncheng ~]# cat /data/wwwroot/abc.com/index.php [root@Dasoncheng ~]# mkdir -p /data/wwwroot/111.com [root@Dasoncheng ~]# cat /data/wwwroot/111.com/index.php
小提示：开启了虚拟主机之后，原先的主配置站点就失效！
虚拟主机配置文件可以定义多个virtual host；每一个host代表一个站点！其中第一个host就变为了主站点，访问ip就是这个主机！
[root@Dasoncheng ~]# curl -x192.168.60.11:80 www.abc.com abc.com ##ServerAlias我就没有测试，下面也没有； [root@Dasoncheng ~]# curl -x192.168.60.11:80 www.111.com 111.com [root@Dasoncheng ~]# vim /etc/hosts [root@Dasoncheng ~]# tail -1 /etc/hosts 192.168.60.11 www.abc.com www.111.com [root@Dasoncheng ~]# curl www.abc.com abc.com [root@Dasoncheng ~]# curl www.111.com 111.com [root@Dasoncheng ~]# curl
