How to solve the problem with bitrix installation related to session support?

Question

1C-Bitrix

I can not install 1-s Bitrix.
Writes in session support:
No. Probably the directory used to save the session parameters is not writable
In .htaccess at the root of the site

Options -Indexes 
ErrorDocument 404 /404.php

<IfModule mod_php5.c>
  #php_flag session.use_trans_sid off
  php_value display_errors 1
  #php_value mbstring.func_overload 2
  #php_value mbstring.internal_encoding UTF-8
</IfModule>

<IfModule mod_rewrite.c>
  Options +FollowSymLinks
  RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-l
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !/bitrix/urlrewrite.php$
  RewriteRule ^(.*)$ /bitrix/urlrewrite.php [L]
  RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization}]
</IfModule>

Answer 1

I decided! extension=session.so in the php.ini file should have been put after session.save_path = /home/p394743/tmp/session
