I'm setting up a Magento 2.1.3 site, first time using M2.
I'm having issues setting up my crontab to re-index etc., looking online it seems that it is a fairly common problem although all of the obvious fixes I found online did not work for me.
Info: Dedicated Server, OS CentOS 6.9, Plesk Onyx 17.0.17
PHP CLI: 5.4.45, Plesk Set PHP: 7.0.18
I've setup the cron info following the DevDocs as seen: http://devdocs.magento.com/guides/v2.0/config-guide/cli/config-cli-subcommands-cron.html#config-cli-cron-bkg
However this of course did not work, so delving deeper into it, I then tried manually running the cron job such as:
./magento indexer:reindex
And I get a PHP Parse error:
PHP Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /var/www/vhosts/DOMAIN/httpdocs/ts_store/vendor/magento/framework/App/Bootstrap.php on line 411
Upon searching, the only issues I can find similar relating to the PHP Parse error are people struggling to install M2 and have been no help for me.
Is anyone able to suggest anything to help?
UPDATE
I am now running PHP 5.6 CLI.
However I am still experiencing issues, If I force the reindex using: ./magento indexer:reindex
The reindex works, however when I setup the cron its not working and I get an undelivered email with an error station permission denied:
/bin/sh: /var/www/vhosts/DOMAIN/httpdocs/ts_store/var/log/setup.cron.log: Permission denied
