关于linux端php实现守护进程

1.编写服务端php脚本

test.php / test

#！/usr/local/php/bin/php
<?php
       ......

2.执行进程  ./test >> /tmp/log.txt &  (后台进程)

 

3.守护进程

#！/usr/local/php/bin/php
<?php
$lock_file = realpath($_SERVER['PHP_SELF']).'.lock';
$lock_file_handle = fopen($lock_file,'w');
if ($lock_file_handle === false) {
   die("Can not create lock ");
}
if (!flock($lock_file_handle,LOCK_EX + LOCK_NB)) {
   die("Process already exists./n");
}

3.查看守护进程 ps -ef | grep php
