環境：centos-6.5
依賴：yum install -y gcc gcc-c++
下載pcre，openssl,openresty
wget https://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz
wget https://www.openssl.org/source/openssl-1.0.1t.tar.gz
wget https://openresty.org/download/openresty-1.9.15.1.tar.gz
全部解壓
cd openresty-1.9.15.1
編譯安裝（指定pcre和openssl的解壓目錄）：
./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
定製日誌格式：
a.前端統一腳本ma.js
(function () {
var params = {};
//Document對象數據
if(document) {
params.domain = document.domain || '';
params.url = document.URL || '';
params.title = document.title || '';
params.referrer = document.referrer || '';
}
//Window對象數據
if(window && window.screen) {
params.sh = window.screen.height || 0;
params.sw = window.screen.width || 0;
params.cd = window.screen.colorDepth || 0;
}
//navigator對象數據
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;
}
}
}
//拼接參數串
var args = '';
for(var i in params) {
if(args != '') {
args += '&';
}
args += i + '=' + encodeURIComponent(params[i]);
}
//通過Image對象請求後端腳本
var img = new Image(1, 1);
img.src = 'http://analytics.codinglabs.org/1.gif?' + args;
})();b.埋點代碼（嵌入到前端頁面中）
<script type="text/javascript">
var _maq = _maq || [];
_maq.push(['_setAccount', '網站標識']);
(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攔截1.gif的請求,定製日誌格式，配置nginx.conf

}注意：
1.log_format tick定製日誌格式 2.location /1.gif攔截所有1.gif的請求，並獲得請求參數 3.location /i-log 日誌落地
