apache配置虛擬主機(三種方式)

查看apache的配置

查找apache的配置文件

[root@localhost ~]# rpm -qc httpd
/etc/httpd/conf.d/autoindex.conf
/etc/httpd/conf.d/userdir.conf
/etc/httpd/conf.d/welcome.conf
/etc/httpd/conf.modules.d/00-base.conf
/etc/httpd/conf.modules.d/00-dav.conf
/etc/httpd/conf.modules.d/00-lua.conf
/etc/httpd/conf.modules.d/00-mpm.conf
/etc/httpd/conf.modules.d/00-proxy.conf
/etc/httpd/conf.modules.d/00-systemd.conf
/etc/httpd/conf.modules.d/01-cgi.conf
/etc/httpd/conf/httpd.conf			//該文件爲httpd的配置文件
/etc/httpd/conf/magic
/etc/logrotate.d/httpd
/etc/sysconfig/htcacheclean
/etc/sysconfig/httpd

查看DocumentRoot

[root@localhost ~]# cat /etc/httpd/conf/httpd.conf | grep "^DocumentRoot"
DocumentRoot "/var/www/html"

DocumentRoot是站點文件的根目錄，html、css、js文件都會以站點作爲文件夾放在該目錄下。

查看配置文件的根目錄

[root@localhost httpd]# cat /etc/httpd/conf/httpd.conf | grep "^ServerRoot"
ServerRoot "/etc/httpd"

配置文件都會存放在"/etc/httpd"目錄下，主配置文件中的相對路徑也是以這個目錄爲參考點。

查看站點配置文件存放位置

[root@localhost ~]# cat /etc/httpd/conf/httpd.conf | grep "^Include"
Include conf.modules.d/*.conf
IncludeOptional conf.d/*.conf

可見主配置文件中將conf.d目錄下的所有.conf文件都include了，故我們可以在conf.d目錄下創建站點的.conf配置文件，也可以另外添加站點配置，形式爲“Include conf_file_path”。

三種方式配置虛擬主機

httpd的虛擬主機也就是虛擬站點，我們通過“基於域名的虛擬主機”、“基於IP地址的虛擬主機”、“基於端口的虛擬主機”三種方式進行配置。

三種方式在配置上的區別也在配置文件上不同，下面配置的例子都將把配置寫在/etc/httpd/conf.d/vhost.conf文件中。

基於域名的虛擬主機

# 接收來自本機任意IP地址的80端口訪問
<VirtualHost *:80>
  # 站點目錄爲/var/www/html/mydomaincom,需手動創建並添加文件
  DocumentRoot /var/www/html/mydomaincom
  ServerName www.mydomain.com
  # 日誌文件，是個相對路徑，可通過查看主配置文件得到其根目錄
  ErrorLog "logs/www.mydomain.com.error_log"
  CustomLog "logs/www.mydomain.com.access_log" common
  # 對站點的子目錄進行訪問限制
  <Directory "/var/www/html/mydomaincom">
    # 開放訪問
    Require all granted
  </Directory>
</VirtualHost>

創建站點html目錄

[root@localhost httpd]# mkdir /var/www/html/mydomaincom

創建站點html文件

[root@localhost httpd]# echo "this is mydomain.html" >> /var/www/html/mydomaincom/index.html

測試

# 重啓httpd服務
[root@localhost httpd]# systemctl restart httpd
# 因爲這是我們自定義的域名，故需添加域名解析
[root@localhost httpd]# echo "192.168.218.6  www.mydomain.com" >> /etc/hosts
[root@localhost httpd]# curl www.mydomain.com
this is mydomain.html
# 訪問成功

基於端口的虛擬主機

配置了兩個站點

<VirtualHost *:8080>
  # 也可以配置ServerName，這裏沒有配
  DocumentRoot  "/var/www/html/8080com"
  ErrorLog "logs/8080com.error_log"
  CustomLog "logs/8080com.access_log" common
  <Directory "/var/www/html/">
    Require all granted
  </Directory>
</VirtualHost>

<VirtualHost *:9090>
  DocumentRoot  "/var/www/html/9090com"
  ErrorLog "logs/9090com.error_log"
  CustomLog "logs/9090com.access_log"  common
  <Directory "/var/www/html/">
    Require all granted
  </Directory>
</VirtualHost>
Listen 8080
Listen 9090

用同樣的方法創建站點目錄和文件

[root@localhost html]# pwd
/var/www/html
[root@localhost html]# tree
.
├── 8080com
│   └── index.html
├── 9090com
│   └── index.html
└── mydomaincom
    └── index.html

3 directories, 3 files

測試

[root@localhost html]# curl 192.168.218.6:8080
this is 8080com.html
[root@localhost html]# curl 192.168.218.6:9090
this is 9090com.html
# 訪問成功

基於IP的虛擬主機

該主機的另一個IP地址爲192.168.31.128

在vhost.conf中添加站點

<VirtualHost 192.168.31.128:80>
  ServerName www.mydomain2.com
  DocumentRoot  "/var/www/html/mydomain2com"
  ErrorLog "logs/mydomain2.error_log"
  CustomLog "logs/mydomain2.access_log"  common
  <Directory "/var/www/html/">
    Require all granted
  </Directory>
</VirtualHost>
Listen 192.168.31.128:80

用上面同樣的方法創建站點目錄和文件

[root@localhost html]# pwd 
/var/www/html
[root@localhost html]# ls
8080com  9090com  mydomain2com  mydomaincom
[root@localhost html]# ls mydomain2com/
index.html

測試

[root@localhost conf.d]# systemctl restart httpd
[root@localhost conf.d]# curl 192.168.31.128
this is mydomain2com
# 訪問成功
