apache认证
apache认证 有时候某些目录下的文件需要增加认证，Apache缺省的认证模块都是很完备的，以下就是一个通过.htaccess文件增加用户认证的例子。即使对于虚拟主机用户也可以通过上传一些文件来实现认证控制。ServerAdmin webmaster@xxx.com.cn
DocumentRoot /data/mrtgwww/
ServerName mrtg.xxc.com.cn
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
Options Indexes FollowSymLinks
AllowOverride AuthConfig
Order allow,deny
Allow from all
首先用htpasswd创建一个密码文件：比如文件名叫做my.passwd
/home/apache/bin/htpasswd -c -b my.passwd myusername mypassword
如果增加帐号：
/home/apache/bin/htpasswd -b my.passwd anotherusername anotherpassword
将my.passwd上传到一个非发布路径下。
比如你的物理WEB根目录的上一级
/home/apache/conf/my.passwd
创建 .htaccess
AuthName "My Authorization Directory"
AuthType Basic
AuthUserFile /home/apache/conf/my.passwd
Require valid-user
将这个文件上传到你需要进行用户认证的目录：
/home/apache/htdocs/admin/.htaccess
这样这个目录的访问就需要认证了。
-c 创建密码文件
# ./htpasswd --help
Usage:
htpasswd [-cmdpsD] passwordfile username
htpasswd -b passwordfile username password
htpasswd -n username
htpasswd -nb username password
-cCreate a new file.
-nDon't update file; display results on stdout.
-mForce MD5 encryption of the password.
-dForce CRYPT encryption of the password (default).
-pDo not encrypt the password (plaintext).
-sForce SHA encryption of the password.
-bUse the password from the command line rather than prompting for it.
-DDelete the specified user.
vi httpd.conf
