No effect from running cron task, sphinx indexing?

Question

linux

in crontab:

0 */4 * * * root /usr/local/sphinx/bin/indexer --rotate --all --config /usr/local/sphinx/etc/sphinx.conf

Those. re-index Sphinx every 4 hours
In cron logs:

Sep  2 08:00:01 user CROND[19093]: (root) CMD (root /usr/local/sphinx/bin/indexer --rotate --all --config /usr/local/sphinx/etc/sphinx.conf)

But, new positions are not added to the search if manually executed in the console

/usr/local/sphinx/bin/indexer --rotate --all --config /usr/local/sphinx/etc/sphinx.conf, то все работает.

What did I do wrong?

Answer 1

Errors that occur during the execution of cron tasks are not written to the cron log, but to the mail of the system administrator - by default. Look in the /var/mail folder if mail is not configured.

Answer 2

you need to make sure that the user for whom the schedule is created in cron has the necessary rights, including execution, for the script called from the schedule

Answer 3

View the result of the execution in the mail
Or redirect the output of the command to a file
