Owncloud new installation, access mysql database, the database into the original database backup. Web access owncloud, suggesting that "need to upgrade, please use the command to upgrade." What can I do?

System prompt reference (https://doc.owncloud.org/server/9.1/admin_manual/configuration_server/occ_command.html#command-line-upgrade) But this page, the order is invalid. Do not know how to use it

My system environment, CentOS 6.6

故障已解除，谢谢！
原因是我执行数据库升级命令的时候，未正确写明php路径导致。

Fault has been lifted, thank you!
The reason is that when I execute the database upgrade command, the php path is not correctly stated.
