CentOS7单机部署lamp环境和apache虚拟主机

（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
