バージョン変更
8.1と7.4が存在しているがデフォルトでは、8.1が実行される状態。
この後に切り替えを行う。
まず、Apache2のモジュールを切り替えます。
root@deto105:~# a2dismod php8.1
Module php8.1 disabled.
To activate the new configuration, you need to run:
systemctl restart apache2
root@deto105:~# a2enmod php7.4
Considering dependency mpm_prefork for php7.4:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Module mpm_prefork already enabled
Considering conflict php5 for php7.4:
Enabling module php7.4.
To activate the new configuration, you need to run:
systemctl restart apache2
root@deto105:~#
root@deto105:/etc/apache2/mods-enabled# a2enmod userdir
Enabling module userdir.
To activate the new configuration, you need to run:
systemctl restart apache2
# vi php7.4.conf
---------------------
<IfModule mod_userdir.c>
<Directory /home/*/public_html>
php_admin_flag engine Off
