linux 系统虚拟主机功能 --基于IP地址同时运行多个网站

利用虚拟主机功能,可以把一台处于运行状态的物理服务器分割成多个“虚拟的服务器”。

 

Apache的虚拟主机功能是服务器基于用户请求的不同IP地址、主机域名或端口号实现一台服务器提供多个网站同时为外部提供访问服务的技术

可以基于三种方式实现:

  • 基于IP地址
  • 基于域名
  • 基于端口号

 

基于IP地址实现同时提供多个网站服务:

如果一台服务器有多个IP地址,而且每个IP地址与服务器上部署的每个网站一一对应,这样当用户请求访问不同的IP地址时, 会访问到不同网站的页面资源

 

1、给虚拟机配置多个IP地址:

[root@PC1linuxprobe html]# nmtui

 

 

2、重启网卡,测试三个IP地址的联通性

[root@PC1linuxprobe html]# systemctl restart network
[root@PC1linuxprobe html]# ping -c 2 192.168.10.10
PING 192.168.10.10 (192.168.10.10) 56(84) bytes of data.
64 bytes from 192.168.10.10: icmp_seq=1 ttl=64 time=0.054 ms
64 bytes from 192.168.10.10: icmp_seq=2 ttl=64 time=0.041 ms

--- 192.168.10.10 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.041/0.047/0.054/0.009 ms
[root@PC1linuxprobe html]# ping -c 2 192.168.10.20
PING 192.168.10.20 (192.168.10.20) 56(84) bytes of data.
64 bytes from 192.168.10.20: icmp_seq=1 ttl=64 time=0.033 ms
64 bytes from 192.168.10.20: icmp_seq=2 ttl=64 time=0.041 ms

--- 192.168.10.20 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.033/0.037/0.041/0.004 ms
[root@PC1linuxprobe html]# ping -c 2 192.168.10.30
PING 192.168.10.30 (192.168.10.30) 56(84) bytes of data.
64 bytes from 192.168.10.30: icmp_seq=1 ttl=64 time=0.031 ms
64 bytes from 192.168.10.30: icmp_seq=2 ttl=64 time=0.039 ms

--- 192.168.10.30 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.031/0.035/0.039/0.004 ms

 

3、创建网站数据目录以及网站首页数据

[root@PC1linuxprobe html]# mkdir -p /home/wwwroot/10
[root@PC1linuxprobe html]# mkdir -p /home/wwwroot/20
[root@PC1linuxprobe html]# mkdir -p /home/wwwroot/30
[root@PC1linuxprobe html]# echo 11111 > /home/wwwroot/10/index.html
[root@PC1linuxprobe html]# echo 22222 > /home/wwwroot/20/index.html
[root@PC1linuxprobe html]# echo 33333 > /home/wwwroot/30/index.html

 

4、修改httpd服务主配置文件,即写入三个基于IP地址的虚拟主机网站参数。

…………
111
# below. 112 # 113 <VirtualHost 192.168.10.10> 114 DocumentRoot /home/wwwroot/10 115 ServerName www.linuxprobe.com 116 <Directory /home/wwwroot/10 > 117 AllowOverride None 118 Require all granted 119 </Directory> 120 </VirtualHost> 121 ############### 122 <VirtualHost 192.168.10.20> 123 DocumentRoot /home/wwwroot/20 124 ServerName bbs.linuxprobe.com 125 <Directory /home/wwwroot/20 > 126 AllowOverride None 127 Require all granted 128 </Directory> 129 </VirtualHost> 130 ############### 131 <VirtualHost 192.168.10.30> 132 DocumentRoot /home/wwwroot/30 133 ServerName tech.linuxprobe.com 134 <Directory /home/wwwroot/30 > 135 AllowOverride None 136 Require all granted 137 </Directory> 138 </VirtualHost> 139 #
…………

 

5、重启httpd服务

[root@PC1linuxprobe html]# systemctl restart httpd

 

6、测试访问网站(均不能查看到首页数据)

 

 

 

 

 

 

7、查看并修改网站数据目录的SElinux上下文

[root@PC1linuxprobe html]# ls -ldZ /var/www/html/  (默认路径的SElinux上下文值)
drwxr-xr-x. root root system_u:object_r:httpd_sys_content_t:s0 /var/www/html/
[root@PC1linuxprobe html]# ls -ldZ /home/wwwroot/ ## 网站数据目录的SElinux上下文值
drwxr-xr-x. root root unconfined_u:object_r:home_root_t:s0 /home/wwwroot/
[root@PC1linuxprobe html]# ls -ldZ /home/wwwroot/10
drwxr-xr-x. root root unconfined_u:object_r:home_root_t:s0 /home/wwwroot/10
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot   ## 修改上下文值
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/10
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/10/*
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/20
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/20/*
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/30
[root@PC1linuxprobe html]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/30/*
[root@PC1linuxprobe html]# restorecon -Rv /home/wwwroot/  ## 立即生效
restorecon reset /home/wwwroot context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/10 context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/10/index.html context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/20 context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/20/index.html context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/30 context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/30/index.html context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
[root@PC1linuxprobe html]# ls -ldZ /home/wwwroot/10  ## 再次查看
drwxr-xr-x. root root unconfined_u:object_r:httpd_sys_content_t:s0 /home/wwwroot/10

 

8、测试效果
