引言

对于一些私有站点，不希望别人轻易访问的，可以使用这个简单的认证模块

使用方法

生成密钥文件

htpasswd -c -m 路径 用户名
如：htpasswd -c -m /etc/nginx/passwd administrator

如果首次使用，要加上-c，如果后续想添加别的用户，就不要再-c了

-m 属性是md5，如果觉得不够安全，可以参考下面的文档。

附上说明文档：

Usage:
htpasswd [-cimBdpsDv] [-C cost] passwordfile username
htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password
-c Create a new file. 新建一个新文件
-n Don't update file; display results on stdout.
-b Use the password from the command line rather than prompting for it.
-i Read password from stdin without verification (for script usage).
-m Force MD5 encryption of the password (default).
-2 Force SHA-256 crypt() hash of the password (very secure).
-5 Force SHA-512 crypt() hash of the password (very secure).
-B Force bcrypt encryption of the password (very secure).
-C Set the computing time used for the bcrypt algorithm
(higher is more secure but slower, default: 5, valid: 4 to 17).
-r Set the number of rounds used for the SHA-256, SHA-512 algorithms
(higher is more secure but slower, default: 5000).
-d Force CRYPT encryption of the password (8 chars max, insecure).
-s Force SHA-1 encryption of the password (insecure).
-p Do not encrypt the password (plaintext, insecure).
-D Delete the specified user.
-v Verify password for the specified user.
On other systems than Windows and NetWare the '-p' flag will probably not work.
The SHA-1 algorithm does not use a salt and is less secure than the MD5 algorithm.

nginx 配置

在server节中配置以下:
need login --> 提示信息
/etc/nginx/password --> 认证文件路径

auth_basic  "need login"; 
auth_basic_user_file  /etc/nginx/password;

apache-httpd

如果需要配置apache-httpd的基本身份认证，可参阅往期文章。
