设置php脚本永不过期

在Linux下运行2个php脚本:queue.php,worker.php

queue.php,worker.php 2个脚本实现的功能:接收&&处理日志信息
应用程序发送日志信息是不定时的,但是queue,worker必须是常驻进程,一直开启等待接收&&处理信息,需要一直执行

在putty上操作运行脚本,但是由于session会过期导致,php中断执行,想要php脚本一直运行,有2个方法

1.如果你的代码已经成熟了,你可以直接把php脚本开成守护进程,让脚本一直运行

<code class=" hljs avrasm">开启守护进程的方法:nohup php queue<span class="hljs-preprocessor">.php</span> &或setsid php queue<span class="hljs-preprocessor">.php</span>[原理nohup :让进程忽略中断退出发出的hangup信号sesid:让进程不属于此终端的子进程,那么自然也不会受到中断的hangup信号的影响]</code>

2.代码还在调试阶段,不开守护进程,如何使php脚本在session过期以后继续运行

<code class=" hljs lasso">路径:/usr/<span class="hljs-built_in">local</span>/php/etc/php<span class="hljs-attribute">-fpm</span><span class="hljs-built_in">.</span>conf有一个参数:request_terminate_timeout <span class="hljs-subst">=</span> <span class="hljs-number">120</span>  <span class="hljs-comment">//默认值是120</span>修改这个参数的值为:<span class="hljs-number">0</span>这样php脚本在运行的时候就会永不过期了,session断开以后,php脚本仍会继续运行:)</code>
