（1）apache介绍 
apache : httpd.apache.org

软件包：httpd

端口服务：80/tcp(http) 443/tcp(https,http+ssl)

配置文件：

	/etc/httpd/conf/httpd.conf

	/etc/httpd/conf.d/*.conf

	/etc/httpd/conf.d/welcome.conf 			//默认测试页面

（2）lamp环境安装

1.关闭防火墙和selinux 

systemctl stop firewalld.service

systemctl disable firewalld.service

sed -ri '/^SELINUX=/cSELINUX=disabled' /etc/sysconfig/selinux

setenforce 0

2.安装和启动apache 

yum install httpd -y

systemctl start httpd

systemctl enable httpd

3.安装php 

yum install php -y 			//php作为apache的模块

yum install php-mysql -y	//安装php连接mysql扩展模块

yum install gd php-gd -y

php -m 						//查看php有哪些扩展模块

ll /etc/httpd/modules/libphp5.so

ll /etc/httpd/conf.d/php.conf

systemctl restart httpd

4.安装mariadb 

yum install mariadb-server mariadb  -y

systemctl start mariadb

systemctl enable mariadb

mysql_secure_installation 		//修改root默认密码

mysql -uroot -p					//登录mariadb测试

5.测试apache和php 

cd /var/www/html

#vim index.php

<?php

phpinfo();

?>

http://192.168.1.2



6.测试php和mariadb 

cd /var/www/html

#vim index.php

<?php

$link=mysql_connect('localhost','root','mysql密码')

if($link)

	echo "successfuly";

else

	echo "Faile";

mysql_close();

?>

http://192.168.1.2



7.apache目录介绍 

# ll /etc/httpd/

conf										//配置文件目录

conf.d										//配置文件目录

conf.modules.d								//模块目录

logs -> ../../var/log/httpd					//日志目录

modules -> ../../usr/lib64/httpd/modules	//模块目录

run -> /run/httpd							//httpd进程pid在这个文件

8.apache配置文件详解 

ServerRoot "/etc/httpd"						//安装目录

Listen 80									//监听端口

User apache									//运行apache的用户

Group apache								//运行apache的用户组

DocumentRoot "/var/www/html"				//站点默认主目录

IncludeOptional conf.d/*.conf				//包含conf.d/*.conf的文件

<Directory "/var/www">						//设定访问控制权限，如果修改了站点主目录，这里也需要修改

    AllowOverride None

    # Allow open access:

    Require all granted						//允许所有主机访问

</Directory>

（3）虚拟主机：基于主机地址

1.配置主机地址www.test.com的虚拟主机 

#vim /etc/httpd/conf.d/blog.conf

<VirtualHost *:80>

    DocumentRoot "/var/www/blog"

    ServerName blog.test.com

    ErrorLog "/var/log/blog-error_log"

    CustomLog "/var/log/blog-access_log" common

</VirtualHost>

<Directory "/var/www/blog">

    AllowOverride None

    Require all granted

</Directory>

2.创建目录,修改属主,准备主页 

mkdir /var/www/blog

chown -R apache.apache /var/www/blog

echo "blog.test.com" >>/var/www/blog/index.html

3.检查配置文件和重启服务 

httpd -t

systemctl restart httpd

4.修改windows的hosts文件 

编辑：C:\Windows\System32\drivers\etc\hosts添加一下记录

192.168.111.151 blog.test.com

5.使用浏览器测试访问
