cronjob 上的 PHP 错误，在提示时工作正常

Question

我正在 cronjob 上运行以下脚本...

cd /etc/parselog/
php run_all.php >/dev/null

并且出现以下错误:

[05-May-2009 20:30:12] PHP Warning:  PHP Startup: Unable to load dynamic library './pdo.so' - ./pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0

[05-May-2009 20:30:12] PHP Fatal error:  Call to undefined function mysql_connect() in /etc/parselog/stats_downloads.php on line 5

但是，当我从命令行运行相同的脚本并登录时，它可以完美无误地运行。

这是我在提示符下的 $PATH 字符串:

$PATH = /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin

有什么想法或建议吗？我确定在运行 cronjob 时，它没有 lib 路径或包含的内容。我什至尝试添加确切的路径

提示 1:确保您在 cron 作业中具有完全相同的 $PATH:

cd /etc/parselog/
export PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin
php run_all.php >/dev/null

提示 2:确保所有其他环境变量也匹配。使用命令 env 转储环境，并将相应的导出添加到您的 cron 作业。
