squid配置

2016年1月19日 by admin·0评论

发现线上squid版本太早，准备升级，配置有很大的改变
参考官方配置文档
http://www.squid-cache.org/Doc/config/

反向代理的配置官方示例
http://wiki.squid-cache.org/ConfigExamples#Reverse_Proxy_.28Acceleration.29

了解几个核心配置选项：
http_port, cache_peer, cache_dir, acl, http_access, visible_hostname, cache_mem
squid配置项很多，也比较复杂，如果只是做个简单反向代理简单配置几项即可工作

日期及时间的计算

2016年1月9日 by admin·0评论

参考 http://php.net/manual/en/refs.calendar.php

function date_step_callback($callback, $start, $stop = null, $step = 'P1D'){
    $date1 = new DateTime($start);
    $date2 = new DateTime($stop);

    while($date1 < $date2){
        $start = $date1->format('Y-m-d');
        $date1->add(new DateInterval($step));

        $stop = $date1->format('Y-m-d');
        $callback($start, $stop);
    }
}

function date_step_callback($callback, $start, $stop = null, $step = 'P1D'){

$date1 = new DateTime($start);

$date2 = new DateTime($stop);

while($date1 < $date2){

$start = $date1->format('Y-m-d');

$date1->add(new DateInterval($step));

$stop = $date1->format('Y-m-d');

$callback($start, $stop);

}

简单弄个getJson()

2015年12月30日 by admin·0评论

有时不得加载jq, 记录一下简单常用的函数

 var getJSON = (function(){
        var loadJsFile = function(file){
            var head = ghead();
            var e = document.createElement("script");
            e.type="text/javascript";
            e.src=file;
            head.appendChild(e);
        };

        var ghead = function(){
            var head, o = document;
            ((head = o.getElementsByTagName('head')[0]) || (head = o.body.parentNode.appendChild(o.createElement("head"))));
            return head;
        }

        return function(url, callback) {
            var tmpCallback = 'JCallback' + Math.ceil(Math.random() * 1000000);
            window[tmpCallback] = function(data){
                callback(data);
            };
            url = url + "&callback=" + tmpCallback ;
            loadJsFile(url);
        }
    })();

var getJSON = (function(){

var loadJsFile = function(file){

var head = ghead();

var e = document.createElement("script");

e.type="text/javascript";

e.src=file;

head.appendChild(e);

};

var ghead = function(){

var head, o = document;

((head = o.getElementsByTagName('head')[0]) || (head = o.body.parentNode.appendChild(o.createElement("head"))));

return head;

}

return function(url, callback) {

var tmpCallback = 'JCallback' + Math.ceil(Math.random() * 1000000);

window[tmpCallback] = function(data){

callback(data);

};

url = url + "&callback=" + tmpCallback ;

loadJsFile(url);

}

})();

没有同相同url地址判断

简单的推送消息服务

2015年12月18日 by admin·0评论

订阅者注册推送地址，关注的事件
服务端将消息存储redis队列
服务端开N个进程，读取redis队列并推送到订阅者url
推送错误进入错误队列
服务定时发送错误队列消息

原型

ini_set('default_socket_timeout', -1);
$server = new swoole_http_server('0.0.0.0', 8081);

$n = 5;
for($i = 0; $i < $n; $i++){
    $server->addProcess(new swoole_process(function($process) {
        $redis = getRedis();
        while($data = $redis->blPop('test_list', 0)){
            echo $process->pid . " work : " .  $data[1] . "\n";
            sleep(1);
        }
    }));
}

function getRedis(){
    static $redis;
    if(!isset($redis)){
        $redis = new Redis();
        $redis->connect('127.0.0.1', 6379, 0);
        $redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_NONE);
    }
    return $redis;
}

$server->on('request', function(swoole_http_request $request, swoole_http_response $response) {
    getRedis()->lPush('test_list', "test info");
    $response->end("<h1>hello swoole. #" . rand(1000, 9999) . "</h1>");
});

$server->start();

ini_set('default_socket_timeout', -1);

$server = new swoole_http_server('0.0.0.0', 8081);

$n = 5;

for($i = 0; $i < $n; $i++){

$server->addProcess(new swoole_process(function($process) {

$redis = getRedis();

while($data = $redis->blPop('test_list', 0)){

echo $process->pid . " work : " . $data[1] . "\n";

sleep(1);

}

}));

}

function getRedis(){

static $redis;

if(!isset($redis)){

$redis = new Redis();

$redis->connect('127.0.0.1', 6379, 0);

$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_NONE);

}

return $redis;

}

$server->on('request', function(swoole_http_request $request, swoole_http_response $response) {

getRedis()->lPush('test_list', "test info");

$response->end("<h1>hello swoole. #" . rand(1000, 9999) . "</h1>");

});

$server->start();

swoole->addProcess(swoole_process)增加的进程不能start()
process结束后会被master进程再次创建，所以要么阻塞或进epoll循环
