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
<?php echo 123; ?>
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
……
<Directory />
AllowOverride none
Require all granted
</Directory>
……
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php
……
<IfModule dir_module>
DirectoryIndex index.html index.php
</IfModule>
……
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

[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
<html><body><h1>It works!</h1></body></html>
1.7 Apache默认虚拟主机
先编辑wins的hosts文件：
域名访问：
编辑httpd.conf开启虚拟主机：
[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 <VirtualHost> block.
#
<VirtualHost *:80>
# ServerAdmin [email protected]
DocumentRoot "/data/wwwroot/abc.com"
ServerName abc.com
ServerAlias www.abc.com 123.com
ErrorLog "logs/abc.com-error_log"
CustomLog "logs/abc.com-access_log" common
</VirtualHost>
<VirtualHost *:80>
# ServerAdmin [email protected]
DocumentRoot "/data/wwwroot/111.com"
ServerName www.111.com
ErrorLog "logs/111.com-error_log"
CustomLog "logs/111.com-access_log" common
</VirtualHost>
编辑index页面：
[root@Dasoncheng ~]# mkdir -p /data/wwwroot/abc.com/
[root@Dasoncheng ~]# cat /data/wwwroot/abc.com/index.php
<?php
echo "abc.com";
?>
[root@Dasoncheng ~]# mkdir -p /data/wwwroot/111.com
[root@Dasoncheng ~]# cat /data/wwwroot/111.com/index.php
<?php
echo "111.com";
?>
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！
测试虚拟主机访问：
[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 http://192.168.60.11
abc.com
apache所有的主机都指向第一个? http://www.aminglinux.com/bbs/thread-491-1-1.html
