全部解压
cd openresty-1.9.15.1
编译安装（指定pcre和openssl的解压目录）：
./configure --prefix=/home/qun/nginx/openresty --with-pcre=/home/qun/nginx/pcre-8.39 --with-http_ssl_module --with-openssl=/home/qun/nginx/openssl-1.0.1t --with-luajit
make
make install
定制日志格式：
a.前端统一脚本ma.js
(function () {
var params = {};
//Document对象数据
if(document) {
params.domain = document.domain || ‘‘;
params.url = document.URL || ‘‘;
params.title = document.title || ‘‘;
params.referrer = document.referrer || ‘‘;
}
//Window对象数据
if(window && window.screen) {
params.sh = window.screen.height || 0;
params.sw = window.screen.width || 0;
params.cd = window.screen.colorDepth || 0;
}
//navigator对象数据
if(navigator) {
params.lang = navigator.language || ‘‘;
}
//解析_maq配置
if(_maq) {
for(var i in _maq) {
switch(_maq[i][0]) {
case ‘_setAccount‘:
params.account = _maq[i][1];
break;
default:
break;
}
}
}
//拼接参数串
var args = ‘‘;
for(var i in params) {
if(args != ‘‘) {
args += ‘&‘;
}
args += i + ‘=‘ + encodeURIComponent(params[i]);
}
//通过Image对象请求后端脚本
var img = new Image(1, 1);
img.src = ‘http://analytics.codinglabs.org/1.gif?‘ + args;
})();
b.埋点代码（嵌入到前端页面中）
<script type="text/javascript">
var _maq = _maq || [];
_maq.push([‘_setAccount‘, ‘网站标识‘]);
(function() {
var ma = document.createElement(‘script‘); ma.type = ‘text/javascript‘; ma.async = true;
ma.src = (‘https:‘ == document.location.protocol ? ‘https://master:18080/sa‘ : ‘http://master:18080/sa‘) + ‘/js/ma.js‘;
alert(ma);
var s = document.getElementsByTagName(‘script‘)[0]; s.parentNode.insertBefore(ma, s);
})();
</script>
c.nginx拦截1.gif的请求,定制日志格式，配置nginx.conf
log_format tick "$msec^A$remote_addr^A$u_domain^A$u_url^A$u_title^A$u_referrer^A$u_sh^A$u_sw^A$u_cd^A$u_lang^A$http_user_agent^A$u_utrace^A$u_account";
server {
listen 18080;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
location /echo {
default_type ‘text/plain‘;
echo ‘hello echo‘;
}
location /lua {
default_type ‘text/plain‘;
content_by_lua ‘ngx.say("hello, lua")‘;
}
location /1.gif {
#伪装成gif文件
default_type image/gif;
#本身关闭access_log，通过subrequest记录log
access_log off;
access_by_lua "
-- 用户跟踪cookie名为__utrace
local uid = ngx.var.cookie___utrace
if not uid then
-- 如果没有则生成一个跟踪cookie，算法为md5(时间戳+IP+客户端信息)
uid = ngx.md5(ngx.now() .. ngx.var.remote_addr .. ngx.var.http_user_agent)
end
ngx.header[‘Set-Cookie‘] = {‘__utrace=‘ .. uid .. ‘; path=/‘}
if ngx.var.arg_domain then
-- 通过subrequest到/i-log记录日志，将参数和用户跟踪cookie带过去
ngx.location.capture(‘/i-log?‘ .. ngx.var.args .. ‘&utrace=‘ .. uid)
end
";
#此请求不缓存
add_header Expires "Fri, 01 Jan 1980 00:00:00 GMT";
add_header Pragma "no-cache";
add_header Cache-Control "no-cache, max-age=0, must-revalidate";
#返回一个1×1的空gif图片
empty_gif;
}
location /i-log {
#内部location，不允许外部直接访问
internal;
#设置变量，注意需要unescape
set_unescape_uri $u_domain $arg_domain;
set_unescape_uri $u_url $arg_url;
set_unescape_uri $u_title $arg_title;
set_unescape_uri $u_referrer $arg_referrer;
set_unescape_uri $u_sh $arg_sh;
set_unescape_uri $u_sw $arg_sw;
set_unescape_uri $u_cd $arg_cd;
set_unescape_uri $u_lang $arg_lang;
set_unescape_uri $u_utrace $arg_utrace;
set_unescape_uri $u_account $arg_account;
#打开日志
log_subrequest on;
#记录日志到ma.log，实际应用中最好加buffer，格式为tick
access_log /home/qun/nginx/openresty/nginx/logs/ma.log tick;
#输出空字符串
echo ‘‘;
}
}
注意：
1.log_format tick定制日志格式 2.location /1.gif拦截所有1.gif的请求，并获得请求参数 3.location /i-log 日志落地
日志：
