linux – cronjob不会执行一个独立运行的脚本

所以你需要说：

1 * * * * /bin/sh /var/www/html/dbsync/dbsync.sh /var/www/html/dbsync
#         ^^^^^^^

/ bin / sh是您要用于执行脚本的二进制文件.

否则,您可以设置脚本的执行权限并添加一个shell-script header,告诉它使用哪个解释器：

#!/bin/sh

如果这样做,则无需添加二进制文件的路径.

从Troubleshooting common issues with cron jobs开始：

Using relative paths. If your cron job is executing a script of some
kind,you must be sure to use only absolute paths inside that script.
For example,if your script is located at /path/to/script.phpand
you’re trying to open a file called file.php in the same directory,
you cannot use a relative path such as fopen(file.php). The file must
be called from its absolute path,like this: fopen(/path/to/file.php).
This is because cron jobs do not necessarily run from the directory in
which the script is located,so all paths must be called specifically.

另外,我知道你想每分钟运行一次.如果是这样,1 * * * *将不会. Intead,它将运行at every 1st minute past every hour.所以如果你想每分钟运行它,比如* * * * *.
