1.6 Apache2.4與php結合

httpd主配置文件/usr/local/apache2.4/conf/httpd.conf
vim /usr/local/apache2.4/conf/httpd.conf //修改如下4個地方
ServerName
Require all denied
AddType application/x-httpd-php .php
DirectoryIndex index.html index.php
/usr/local/apache2.4/bin/apachectl -t //測試語法
/usr/local/apache2.4/bin/apachectl start //啓動服務
netstat -lntp
curl localhost
vim /usr/local/apache2.4/htodcs/test.php //增長以下內容

<?php echo 123; ?> php

curl localhost/test.phphtml

要想實現php的效果先編輯Apache測試文件！linux

[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>
……

這裏插入Linux防火牆知識：
selinux //臨時關閉 setenforce 0
selinux //永久關閉 vi /etc/selinux/config
centos7以前使用netfilter防火牆、
centos7開始使用firewalld防火牆
關閉firewalld開啓netfilter方法:
systemctl stop firewalld
systemctl disable firewalld
yum install -y iptables-services
systemctl enable iptables
systemctl start iptablesweb

##關於selinux：
##臨時關閉：
[root@Dasoncheng ~]# getenforce
Enforcing
[root@Dasoncheng ~]# setenforce 0
[root@Dasoncheng ~]# getenforce
Permissive
##永久關閉：
[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

##關於關閉firewalld開啓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  ]

編輯好了httpd.conf以後，測試：apache

[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

[root@Dasoncheng ~]# netstat -lntp |grep httpd
tcp6       0      0 :::80                   :::*                    LISTEN      22383/httpd  
[root@Dasoncheng ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT

訪問測試：

若是沒法訪問，從selinux、防火牆、端口等進行排查！vim

[root@Dasoncheng ~]# curl localhost
<html><body><h1>It works!</h1></body></html>

1.7 Apache默認虛擬主機

先編輯wins的hosts文件：

域名訪問：
centos

編輯httpd.conf開啓虛擬主機：

[root@Dasoncheng ~]# vim /usr/local/apache2.4/conf/httpd.conf    ##編輯主配置文件，開啓虛擬主機（開啓以後，原站點就會失效！）
[root@Dasoncheng ~]# grep -A1 'Virtual hosts' /usr/local/apache2.4/conf/httpd.conf
# Virtual hosts
Include conf/extra/httpd-vhosts.conf

編輯虛擬主機配置文件：

[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 webmaster@dummy-host.example.com
    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 webmaster@dummy-host2.example.com
    DocumentRoot "/data/wwwroot/111.com"
    ServerName www.111.com
    ErrorLog "logs/111.com-error_log"
    CustomLog "logs/111.com-access_log" common
</VirtualHost>

編輯index頁面：

[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：開啓了虛擬主機以後，原先的主配置站點就失效！
虛擬主機配置文件能夠定義多個virtual host；每個host表明一個站點！其中第一個host就變爲了主站點，訪問ip就是這個主機！app

測試虛擬主機訪問：

[root@Dasoncheng ~]# curl -x192.168.60.11:80 www.abc.com
abc.com
##ServerAlias我就沒有測試，下面也沒有；
[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
