This is an issue with your local configuration. The install app requires read/write access to the path that your PHP configuration defines for the session.save_path variable to write session data. If session.save_path doesn't have a value, then the path returned by sys_get_temp_dir() is used instead.

only to say, when I change on the same place to php 5.6. it installs without any problems!

[mbabker]

Check for differences between the PHP 5.6 and 7.0 configurations. It is not an issue of PHP version incompatibility.

Same error:

PHP Warning: session_start(): Failed to read session data: user (path: /tmp) in /var/www/html/libraries/joomla/session/session.php on line 654

@alexz18 This is a very old issue. Please do not comment on such old issues.

Please check the PHP configuration as told by mbabker If there is still a issue please get in contact with your hoster or ask in the forums at https://forum.joomla.org thanks!

I am having the same issue with PHP 7, tried different directories for session.save_path, made sure the permissions were correct (directory owned by http user). Installing and enabling PHP 5.6 fixed the problem

[mbabker]

This is not an issue in the core Joomla install unfortunately; Joomla core runs correctly on all stable PHP releases. The fact that it works on PHP 5.6 and not on PHP 7 is indicative of a server misconfiguration.

Just wanted to comment that I eventually fixed my problem by enabling mysqli.so in my php.ini for PHP7

@mbabker
Does that mean that we should check for the mysqli extension in core?

[brianteeman]

mysqli is enabled by default in php7 and mysql is not present at all in php 7 - to me this was just a bad install/configuration of php

[wkoomson]

Yeah I guess it's poor configuration on my part since I'm using a MariaDB database, but I will note that a fresh install of PHP 7 on Arch Linux has mysqli.so disabled. https://git.archlinux.org/svntogit/packages.git/tree/trunk/php.ini.patch?h=packages/php

I know this topic is closed but it has more discussion than I am finding elsewhere. I changed my tmp folder to 775 and 777 (yikes) and still no go. My php ini has this set to this dir and mysqli.so enabled. Any ideas or should I file a ticket with the host?

[mbabker]

Go to your host. Joomla core has worked correctly with PHP 7 since Joomla 3.5.0 was released.

If you're able to consistently reproduce an issue that might look like a core bug, feel free to open a new item.

[poproar]

found it: mysqli.so is not enabled by the host :(
Thanks @mbabker

For me solution was remove : symbol in configuration.php in $host variable
