Nginx访问日志格式设置
自定义一下nginx的访问日志格式，可以方便工作中的对日志的分析。主要要使用到几个指令，分别是log_format和access_log、error_log
Example：
#WebLog
log_format weblog '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data/logs/domain_access.log access;
error_log /data/logs/domain_error.log error;log_format指令：
------------------------------------- 语法 log_format name string ... ------------------------------------- 默认值 combined "..." ------------------------------------- 使用字段 http -------------------------------------参数说明：
- []$remote_addr 和 $http_x_forwarded_for：记录客户端的ip地址。[/][]$remote_user：记录客户端用户名称。[/][]$time_local：记录访问时间与时区。[/][]$request：记录请求的URL与HTTP协议。[/][]$status：记录请求状态；成功是200。[/][]$body_bytes_sent：记录发送给客户端文件主体内容大小。[/][]$http_referer：记录从那个页面链接访问过来的。[/][]$http_user_agent：记录客户端浏览器的相关信息。[/]
-------------------------------------------------------- 语法 access_log path [ format [ buffer = size ]] access_log off -------------------------------------------------------- 默认值 logs/access.log combined -------------------------------------------------------- 使用字段 http server location if in location limit_except ---------------------------------------------------------记录的日志格式如下：
66.249.73.68 - - [17/Dec/2015:17:03:52 +0800] "GET /2011/11/1659.html HTTP/1.1" 200 9028 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 115.28.133.87 - - [17/Dec/2012:17:03:53 +0800] "GET /2012/03/8907.html HTTP/1.1" 200 8044 "http://www.baidu.com/s?wd=web%20equation&ie=utf-8" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E)" 115.28.133.87 - - [17/Dec/2012:17:03:54 +0800] "GET /favicon.ico HTTP/1.1" 200 1150 "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E; 360SE)"
