My開発メモ

apacheを起動するとphp7.4.soがないと言われた

これは、システムがphp8にアップグレードしたからである。

$ apachectl configtest
apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/mods-enabled/php7.4.load: Cannot load /usr/lib/apache2/modules/libphp7.4.so into server: /usr/lib/apache2/modules/libphp7.4.so: cannot open shared object file: No such file or directory
Action 'configtest' failed.
The Apache error log may have more information.
