# 创建黑名单文件
echo 'deny 192.168.0.132;' >> balck.ip
#http 配置块中引入 黑名单文件
include       black.ip;

log_format格式变量：
    $remote_addr  #记录访问网站的客户端地址
    $remote_user  #远程客户端用户名
    $time_local  #记录访问时间与时区
    $request  #用户的http请求起始行信息
    $status  #http状态码，记录请求返回的状态码，例如：200、301、404等
    $body_bytes_sent  #服务器发送给客户端的响应body字节数
    $http_referer  #记录此次请求是从哪个连接访问过来的，可以根据该参数进行防盗链设置。
    $http_user_agent  #记录客户端访问信息，例如：浏览器、手机客户端等
    $http_x_forwarded_for  #当前端有代理服务器时，设置web节点记录客户端地址的配置，此参数生效的前提是代理服务器也要进行相关的x_forwarded_for设置
将日志配置放在http块里面即可。
