Apache服务
top4：虚拟网站主机功能
Apache虚拟主机功能是可以让一台服务器基于IP、主机名、端口实现提供多个网站服务
p1：基于IP地址
使用nmtui命令为网卡添加多个IP地址（192.168.200.102/103/104）：
[root@CnBlogs ~]# nmtui
重启网络服务：
[root@CnBlogs ~]# systemctl restart network
分别创建网站数据目录：
[root@CnBlogs ~]# mkdir -p /home/wwwroot/102[root@CnBlogs ~]# mkdir -p /home/wwwroot/103[root@CnBlogs ~]# mkdir -p /home/wwwroot/104
分别将数据写入各个网站的index.html文件中：
[root@CnBlogs ~]# echo "ip: 192.168.200.102" >> /home/wwwroot/102/index.html[root@CnBlogs ~]# echo "ip: 192.168.200.103" >> /home/wwwroot/103/index.html[root@CnBlogs ~]# echo "ip: 192.168.200.104" >> /home/wwwroot/104/index.html
在配置文件中添加描述基于IP地址：
<VirtualHost 192.168.200.102>DocumentRoot /home/wwwroot/102ServerName www.CnBlogs.com<Directory /home/wwwroot/102>AllowOverride NoneRequire all granted</Directory></VirtualHost> <VirtualHost 192.168.200.103>DocumentRoot /home/wwwroot/103ServerName news.CnBlogs.com<Directory /home/wwwroot/103>AllowOverride NoneRequire all granted</Directory></VirtualHost> <VirtualHost 192.168.200.104>DocumentRoot /home/wwwroot/104ServerName bbs.CnBlogs.com<Directory /home/wwwroot/104>AllowOverride NoneRequire all granted</Directory></VirtualHost>
修改网站数据目录的selinux安全上下文：
[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/102/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/102/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/103/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/103/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/104[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/104/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/
恢复selinux安全上下文：
[root@CnBlogs ~]# restorecon -Rv /home/wwwroot/[root@CnBlogs ~]# systemctl restart httpd.service
结果：
p2：基于主机名
配置本地hosts解析：
[root@CnBlogs ~]# echo "192.168.200.102 www.cnblogs.com" >> /etc/hosts[root@CnBlogs ~]# echo "192.168.200.103 news.cnblogs.com" >> /etc/hosts[root@CnBlogs ~]# echo "192.168.200.104 bbs.cnblogs.com" >> /etc/hosts[root@CnBlogs ~]# cat /etc/hosts | grep "cnblogs" 192.168.200.102 www.cnblogs.com 192.168.200.103 news.cnblogs.com 192.168.200.104 bbs.cnblogs.com
创建网站数据目录：
[root@CnBlogs ~]# mkdir -p /home/wwwroot/www[root@CnBlogs ~]# mkdir -p /home/wwwroot/news[root@CnBlogs ~]# mkdir -p /home/wwwroot/bbs
分别写入数据到各个网站：
[root@CnBlogs ~]# echo "www.cnblogs.com" >> /home/wwwroot/www/index.html[root@CnBlogs ~]# echo "news.cnblogs.com" >> /home/wwwroot/news/index.html[root@CnBlogs ~]# echo "bbs.cnblogs.com" >> /home/wwwroot/bbs/index.html
修改配置文件：
[root@CnBlogs ~]# vim /etc/httpd/conf/httpd.conf <VirtualHost 192.168.200.102> DocumentRoot /home/wwwroot/www ServerName "www.CnBlogs.com" <Directory /home/wwwroot/www> AllowOverride None Require all granted </Directory> </VirtualHost> <VirtualHost 192.168.200.103> DocumentRoot /home/wwwroot/news ServerName "news.CnBlogs.com" <Directory /home/wwwroot/news> AllowOverride None Require all granted </Directory> </VirtualHost> <VirtualHost 192.168.200.104> DocumentRoot /home/wwwroot/bbs ServerName "bbs.CnBlogs.com" <Directory /home/wwwroot/bbs> AllowOverride None Require all granted </Directory> </VirtualHost>
重启apache：
[root@CnBlogs ~]# systemctl restart httpd.service
修改网站目录的selinux安全上下文：
[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/www/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/www/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/news/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/news/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbs/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbs/*
结果：
需要在本地hosts文件添加解析记录
p3：基于端口号
创建网站数据目录：
[root@CnBlogs ~]# mkdir -p /home/wwwroot/6666[root@CnBlogs ~]# mkdir -p /home/wwwroot/8888
写入数据到网站目录：
[root@CnBlogs ~]# echo "port:6666" >> /home/wwwroot/6666/index.html[root@CnBlogs ~]# echo "port:8888" >> /home/wwwroot/8888/index.html
编辑配置文件：
[root@CnBlogs ~]# vim /etc/httpd/conf/httpd.conf
- 添加监听端口
Listen 6666Listen 8888
- 修改配置文件
<VirtualHost 192.168.200.102:6666>DocumentRoot /home/wwwroot/6666ServerName www.CnBlogs.com<Directory /home/wwwroot/6666>AllowOverride NoneRequire all granted</Directory></VirtualHost> <VirtualHost 192.168.200.102:8888>DocumentRoot /home/wwwroot/8888ServerName news.CnBlogs.com<Directory /home/wwwroot/8888>AllowOverride NoneRequire all granted</Directory></VirtualHost>
重启apache：
[root@CnBlogs ~]# systemctl restart httpd.service
设置网站目录的selinux安全上下文：
[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6666/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/6666/*[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/8888/[root@CnBlogs ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/8888/*
设置selinux服务中有关http服务的端口号：
[root@CnBlogs ~]# semanage port -l | grep -e "^http_port_t"http_port_t ??????tcp ?????80, 81, 443, 488, 8008, 8009, 8443, 9000[root@CnBlogs ~]# semanage port -a -t http_port_t -p tcp 6666[root@CnBlogs ~]# semanage port -a -t http_port_t -p tcp 8888[root@CnBlogs ~]# semanage port -l | grep -e "^http_port_t"http_port_t ????tcp ?????8888, 6666, 80, 81, 443, 488, 8008, 8009,
添加防火墙规则（允许6666、8888端口）：
[root@CnBlogs ~]# firewall-cmd --permanent --add-port=6666/tcpsuccess[root@CnBlogs ~]# firewall-cmd --permanent --add-port=8888/tcpsuccess[root@CnBlogs ~]# firewall-cmd --reloadsuccess[root@CnBlogs ~]# firewall-cmd --permanent --list-ports6666/tcp 8888/tcp
结果：
linux[基础]-29-[Apache服务]-[虚拟主机]-[04]
