虚拟主机功能

此实验的操作均在虚拟机中完成

方式一：基于IP地址

在本机配置3个IP

nmtui

# 192.168.1.100/24
# 192.168.1.101/24
# 192.168.1.102/24

# 配置好后重启网络
# ping一下3个IP，确保IP均可正常访问

创建网站目录及首页文件

mkdir -p /home/wwwroot/100
mkdir -p /home/wwwroot/101
mkdir -p /home/wwwroot/102

echo "IP: 192.168.1.100" > /home/wwwroot/100/index.html
echo "IP: 192.168.1.101" > /home/wwwroot/101/index.html
echo "IP: 192.168.1.102" > /home/wwwroot/102/index.html

编辑httpd服务的配置文件

vim /etc/httpd/conf/httpd.conf

# 添加下方信息（有注释内容的配置文件的113行）
# 无注释的配置文件则添加在DocumentRoot参数上方


<VirtualHost 192.168.1.100>
    DocumentRoot /home/wwwroot/100
    ServerName www.will.com
    <Directory /home/wwwroot/100>
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost 192.168.1.101>
    DocumentRoot /home/wwwroot/101
    ServerName www.will.com
    <Directory /home/wwwroot/101>
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost 192.168.1.102>
    DocumentRoot /home/wwwroot/102
    ServerName www.will.com
    <Directory /home/wwwroot/102>
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

配置SELinux上下文

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/100
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/100/*

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/101
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/101/*

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/102
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/102/*

重启httpd服务

systemctl restart httpd

systemctl enable httpd

访问测试

# 在浏览器中打开下方链接

http://192.168.1.100
http://192.168.1.101
http://192.168.1.102

方式二：基于主机域名

配置解析文件

vim /etc/hosts


# 写入以下信息

192.168.1.100 www.will.com bbs.will.com tech.will.com

# 验证解析

ping -c 4 www.will.com

ping -c 4 bbs.will.com

ping -c 4 tech.will.com

创建网站目录及首页文件

mkdir -p /home/wwwroot/www
mkdir -p /home/wwwroot/bbs
mkdir -p /home/wwwroot/tech

echo "www.will.com" > /home/wwwroot/www/index.html
echo "bbs.will.com" > /home/wwwroot/bbs/index.html
echo "tech.will.com" > /home/wwwroot/tech/index.html

编辑httpd服务的配置文件

vim /etc/httpd/conf/httpd.conf

# 添加下方信息（有注释内容的配置文件的113行）
# 无注释的配置文件则添加在DocumentRoot参数上方


<VirtualHost 192.168.1.100>
    DocumentRoot "/home/wwwroot/www"
    ServerName "www.will.com"
        <Directory "/home/wwwroot/www">
            AllowOverride None
            Require all granted
        </Directory>
</VirtualHost>

<VirtualHost 192.168.1.100>
    DocumentRoot "/home/wwwroot/bbs"
    ServerName "bbs.will.com"
        <Directory "/home/wwwroot/bbs">
            AllowOverride None
            Require all granted
        </Directory>
</VirtualHost>

<VirtualHost 192.168.1.100>
    DocumentRoot "/home/wwwroot/tech"
    ServerName "tech.will.com"
        <Directory "/home/wwwroot/tech">
            AllowOverride None
            Require all granted
        </Directory>
</VirtualHost>

配置SELinux上下文

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/www
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/www/*

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbs
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbs/*

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/tech
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/tech/*

restorecon -Rv /home/wwwroot

重启httpd服务

systemctl restart httpd

systemctl enable httpd

访问测试

# 在浏览器中打开下方链接

http://www.will.com
http://bbs.will.com
http://tech.will.com

方式三：基于端口号

创建网站目录及首页文件

mkdir -p /home/wwwroot/6111
mkdir -p /home/wwwroot/6222

echo "port: 6111" > /home/wwwroot/6111/index.html
echo "port: 6222" > /home/wwwroot/6222/index.html

编辑httpd服务的配置文件

vim /etc/httpd/conf/httpd.conf


# 添加下方信息（有注释内容的配置文件的43行）
# 无注释的配置文件则添加在Listen 80参数下方

Listen 6111
Listen 6222


# 添加下方信息（有注释内容的配置文件的113行）
# 无注释的配置文件则添加在DocumentRoot参数上方


<VirtualHost 192.168.1.100:6111>
    DocumentRoot "/home/wwwroot/6111"
    ServerName www.will.com
    <Directory "/home/wwwroot/6111">
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost 192.168.1.100:6222>
    DocumentRoot "/home/wwwroot/6222"
    ServerName www.will.com
    <Directory "/home/wwwroot/6222">
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

配置SELinux上下文

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6111
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6111/*

semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6222
semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6222/*

restorecon -Rv /home/wwwroot

配置SELinux域

semanage port -l | grep http

semanage port -a -t http_port_t -p tcp 6111
semanage port -a -t http_port_t -p tcp 6222

# 若不设置SELinux域，启动服务将报错
# 提示权限拒绝：绑定端口失败

重启httpd服务

systemctl restart httpd

systemctl enable httpd

访问测试

# 在浏览器中打开下方链接

http://192.168.1.100:6111
http://192.168.1.101:6222
