Nginx 访问认证

server {
        listen       80;
        server_name  blog.abc.com;
        location / {
            root   html/blog;
            index  index.html index.htm;
            auth_basic            "xxxxxxxxxx";                     # 设置用于认证的提示字符串
            auth_basic_user_file  /usr/local/nginx/conf/htpasswd;   # 设置认证的密码文件
        }
    }

yum install -y httpd                                   # 要用到http的工具htpasswd来产生账号和密码，所以要先安装http
htpasswd -bc /usr/local/nginx/conf/htpasswd abc 1234   # 设置认证的账号密码，会保存在密码文件中，第一次使用要用-bc参数
htpasswd -b /usr/local/nginx/conf/htpasswd def 5678    # 以后使用无需加-c参数
chmod 400 /usr/local/nginx/conf/htpasswd
chown nginx /usr/local/nginx/conf/htpasswd
/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
