Linux apache配置虛擬主機

1.進入/usr/local/apache/conf/httpd.conf,
  註釋掉:DocumentRoot "/usr/local/apache/htdocs",該成：DocumentRoot "/var/www/";
  啓用：Include conf/extra/httpd-vhost.conf;

2.修改配置文件的的Allowoverride(兩處都修改了)

3.肯定apache配置文件httpd.conf下安裝了路由重寫模塊並開啓了路由重寫模塊。
 （源碼編譯方式安裝不會自動安裝模塊）。
  文件路徑：usr/local/apache/conf/original/httpd.conf
（路徑：LoadModule rewrite_module modules/mod_rewrite.so）

3.虛擬機配置文件添加路由重寫文件
<VirtualHost 123.45.23.76:80>
    ServerAdmin 123.45.23.76
    DocumentRoot "/var/www/gcash"
    ServerName 123.45.23.76
    ErrorLog "logs/dummy-host2.example.com-error.log"
    CustomLog "logs/dummy-host2.example.com-access.log" common
    
    <Directory "/var/www/gcash">
        Options +FollowSymlinks
        RewriteEngine On

        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
    </Directory>
    
</VirtualHost>

可是配置成上面的形式可能會致使部分的文件沒法解析，即一些能夠訪問，
一些不能訪問，因此，咱們增長解，析配成下面的形式：
<VirtualHost 123.45.23.76:80>
    ServerAdmin 123.45.23.76
    DocumentRoot "/var/www/gcash
    ServerName 123.45.23.76
    ErrorLog "logs/dummy-host2.example.com-error.log"
    CustomLog "logs/dummy-host2.example.com-access.log" common

    DirectoryIndex index.php index.html (新增長的一行)
    
    <Directory "/var/www/gcash">
        Options +FollowSymlinks
        RewriteEngine On

        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
    </Directory>
    
</VirtualHost>
