Question

我有这样的问题：当负载增加到每秒脚本200次查询时，phpcassa会导致此类异常

Error connecting to localhost:9160: TException: TSocket: Could not connect to localhost:9160 (Cannot assign requested address [99])
Error connecting to localhost:9160: TException: TSocket: Could not connect to localhost:9160 (Cannot assign requested address [99])
PHP Fatal error:  Uncaught exception 'NoServerAvailable' with message 'An attempt was made to connect to every server twice, but all attempts failed. The last error was: TException:TSocket: Could not connect to localhost:9160 (Cannot assign requested address [99])' in /var/www/megaumnik/context/connection.php:232

脚本有来自不同列族的4 $ cf-＆gt; get（）。每个列族有1000行

Answer 1

听起来好像你正在达到打开文件限制。您可以通过'ulimit -a'查看当前限制。

要增加限制，您可以通过以下两种方式之一设置新限制。首先，您可以执行类似'ulimit -n 10000'的操作，这是临时的，并且只会影响该shell启动的进程。要永久增加限制，您需要在/etc/security/limits.conf中添加一行，如下所示：

*               -       nofile      10000

为了使此生效，我相信您需要再次登录。

无法使用phpcassa连接到localhost：9160
