nginx配置用户名密码登陆

 

面试中问到这个问题，之前做过tomcat的登陆认证，nginx如下：

-- 使用模块：

　　ngx_http_auth_basic_module ：实现让用户只有输入正确的用户名密码才允许访问web内容

-- 安装httpd工具：

yum -y install httpd

-- 用命令htpasswd生成密码文件：-c指定密码文件，后面自定义登陆的用户名

htpasswd -c /etc/nginx/passwd nginxuser

 

--配置nginx： 

　　配置文件server内新增加如下两行：

auth_basic "Please input password"; #这里是验证时的提示信息 
auth_basic_user_file /etc/nginx/passwd;

　　nginx -t 　　#验证配置OK

　　service nginx restart   #重启生效 

 

--附htpasswd命令：

Usage:
	htpasswd [-cimBdpsDv] [-C cost] passwordfile username
	htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password

	htpasswd -n[imBdps] [-C cost] username
	htpasswd -nb[mBdps] [-C cost] username password
 -c  Create a new file.
 -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).
 -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 31).
 -d  Force CRYPT encryption of the password (8 chars max, insecure).
 -s  Force SHA 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 algorithm does not use a salt and is less secure than the MD5 algorithm.
