配置http支持php及虚拟主机
配置httpd支持php[*]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这个打开后开启httpd后没有警告
Require all denied 这个修改为Require all granted 防止打开虚拟主机配置文件时403
AddType application/x-httpd-php .php 加上这行才可以解析php
DirectoryIndex index.html index.php添加默认索引页
DocumentRoot "/usr/local/apache2.4/htdocs" 这个参数可以定义网站的域名根目录
[*]/usr/local/apache2.4/bin/apachectl -t //测试语法，改完配置需要先检查下再加载
[*]/usr/local/apache2.4/bin/apachectl graceful//重新加载配置文件,不重启服务
[*]iptables -I INPUT -p tcp --dport 80 -j ACCEPT//打开80端口
[*]netstat -lntp //查看80端口
# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1122/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2094/master
tcp6 0 0 :::3306 :::* LISTEN 2658/mysqld
tcp6 0 0 :::80 :::* LISTEN 2387/httpd
tcp6 0 0 :::22 :::* LISTEN 1122/sshd
tcp6 0 0 ::1:25 :::* LISTEN 2094/master
[*]在物理机浏览器上打开主机ip地址能访问
[*]打不开ip主页排查思路
-现在物理机上查看Ip能不能ping通，telnet能不能通，再查看虚拟机上有没有打开80端口
# iptables -I INPUT -p tcp --dport 80 -j ACCEPT
# iptables -nvL
Chain INPUT (policy ACCEPT 58 packets, 3900 bytes)
pkts bytes target prot opt in out source destination
0 0 ACCEPT tcp--* * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80
[*]写一个测试php,vim /usr/local/apache2.4/htdocs/1.php
# vim /usr/local/apache2.4/htdocs/1.php
[*]在物理机浏览器上打开主机ip地址/1.php，可以打开php信息页面，如果不支持php解析的话，访问该文件时会显示源代码。
[*] 故障排查
[*] 检查Apache是否已加载PHP模块
# /usr/local/apache2.4/bin/apachectl -M

[*]查看php模块文件
# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
# ls /usr/local/apache2.4/modules/libphp5.so
/usr/local/apache2.4/modules/libphp5.so
[*]查看apache配置文件这四项
#LoadModule php5_module modules/libphp5.so
LoadModule php7_module modules/libphp7.so
ServerName www.example.com:80
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
Addtype application/x-httpd-php .php
AllowOverride none
Require all granted
[*]“/usr/local/apache2.4/bin/apachectl -t”检查配置文件是否存在语法错误
[*]配置PHP7解析只需要把配置文件中加载的php模块换成php7的，其他相同
[*]ctrl+r用途：反向搜索并调用执行过的命令。(reverse-i-search)。
使用方法：按ctrl+r后命令行会变成“(reverse-i-search)`‘: ”状态，然后输入使用过的参数，此时会直接显示出相关的命令，回车即可执行该命令。
httpd的默认虚拟主机
[*]windows定义hosts
[*]C:\Windows\System32\drivers\etc\hosts
192.168.21.128 www.abc.com www.123.com
[*]可以ping检查下是不是解析到你需要的ip
[*]一台服务器可以访问多个网站，每个网站都是一个虚拟主机
[*]概念：域名（主机名）、DNS(域名解析系统)、hosts(局域网的域名解析)
[*]任何一个域名解析到这台机器，都可以访问的虚拟主机就是默认虚拟主机
[*]vim /usr/local/apache2/conf/httpd.conf
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
打开这个选项，启用虚拟主机配置文件/usr/local/apache2.4/conf/extra/httpd-vhosts.conf
[*]vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf
DocumentRoot "/data/wwwroot/abc.com"
ServerName abc.com
ServerAlias www.abc.com www.123.com
ErrorLog "logs/abc.com-error_log"
CustomLog "logs/abc.com-access_log" common
DocumentRoot "/data/wwwroot/111.com"
ServerName 111.com
ServerAlias www.example.com
ErrorLog "logs/111.com-error_log"
CustomLog "logs/111.com-access_log" common
[*]创建目录
# mkdir /data/wwwroot
# mkdir /data/wwwroot/abc.com
# mkdir /data/wwwroot/111.com
[*]创建index.php文件
# vim /data/wwwroot/abc.com/index.php
# vim /data/wwwroot/111.com/index.php
