Types
bool
Default
true
Constant
GuzzleHttp\RequestOptions::HTTP_ERRORS
$client->request('GET', '/status/500');
// Throws a GuzzleHttp\Exception\ServerException

beanstalkd 安装和配置

安装
安装以centos为例

yum  install beanstalkd

配置

使用centos yum安装，通过查看服务脚本发现有这个配置文件

cat /etc/sysconfig/beanstalkd

主要修改几个地方
ADDR=-l 10.1.3.16 # 修改为内网或本地地址，否则会开放外网非常危险
PORT=-p 11111 # 修改下端口
BINLOG_DIR=-b /var/lib/beanstalkd/binlog # 启用二进制日志防止意外断电或重启导致数据丢失

 

客户端连接问题：

Connection error 113: No route to host

解决办法：防火墙开放对应端口

性能：

$start = microtime(true);
for ($i = 0; $i < 100000; $i ++) {
    $beansClient->useTube('myAwesomeTube')->put("哈哈哈job's payload呵呵呵呵");
}
echo microtime(true) - $start, "\n";

插入一万条数据一秒(本地连接)

插入十万条数据十秒(本地连接)

插入一万条数据14秒(内网连接)

本地取出1w条数据要1.5秒

内网取出1w条数据要33秒

本地取出 1173359条数据 要 200秒

结论：吃内存，快还是慢你觉得呢？

RabbitMQ 简单队列

我想要的是定时任务延时队列，似乎不满足需求，现在用redis做的队列又可以满足大部分需求，先放着吧

    # 推送到队列
    public function aa032() {
        $connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
        $channel = $connection->channel();
        
        $channel->queue_declare('hello', false, false, false, false);
        
        $msg = new AMQPMessage('Hello World 233!');
        $channel->basic_publish($msg, '', 'hello');
        
        echo " [x] Sent 'Hello World 233!'\n";
        
        $channel->close();
        $connection->close();
    }

    # 守护处理队列
    public function aa033() {
        $connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
        $channel = $connection->channel();
        
        $channel->queue_declare('hello', false, false, false, false);
        
        echo " [*] Waiting for messages. To exit press CTRL+C\n";
        
        $callback = function ($msg) {
            echo ' [x] Received ', $msg->body, "\n";
        };
        
        $channel->basic_consume('hello', '', false, true, false, false, $callback);
        
        while (count($channel->callbacks)) {
            $channel->wait();
        }
    }
