1.一般做二次验证：

apache2-utils
mini-httpd
#以上2个包都带htpasswd工具
#sudo   apt-get   install  install  apache2-utils 或 mini-httpd
#htpasswd -b -c /usr/local/nginx/conf/nginx_passwd  kkk kkk   #创建验证文件并添加用户
#htpasswd -b /usr/local/nginx/conf/nginx_passwd  ppp  kkk     #添加验证用户
#htpasswd -D  /usr/local/nginx/conf/nginx_passwd  ppp    #删除用户ppp

2.nginx配置：

server {listen 80 default_server;server_name localhost;root /data/www/t1;index index.php index.html index.htm;#对app目录开启验证location  /app {location ~ .*\.(php|php5)?$ {#fastcgi_pass unix:/tmp/php-cgi.sock;fastcgi_pass  127.0.0.1:9000;fastcgi_index index.php;include fcgi.conf;}#以下验证方式：基本验证auth_basic "input you user name and  password";auth_basic_user_file /etc/nginx/conf.d/nginx_passwd;#auth_basic_user_file conf.d/nginx_passwd; #验证文件配置在ngix目录，不可以配置网站目录下}#对pkg开启目录列表location  /pkg {autoindex on;autoindex_exact_size off;autoindex_localtime on;}

3.apache2配置：

<VirtualHost 127.0.0.1:8081>#ServerName www.example.comServerAdmin webmaster@localhostDocumentRoot /var/www/html<Directory /var/www/html/phpmyadmin>Options Indexes FollowSymLinksAllowOverride authconfig  #自动寻找网站根目录下的.htaccess文件order allow,denyallow from all#Require all granted</Directory>#<Directory /var/www/html/pkg>##对pkg开启目录列表Options IndexesIndexOptions NameWidth=25 Charset=UTF-8 Order allow,denyAllow from all</Directory>#Include conf-available/serve-cgi-bin.conf
