今天剛更新完 apache ，啟動時出現錯誤訊息：

Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP.

後來發現原來是

libphp5.so included with php-apache does not work with mod_mpm_event

解決辦法：

replace

LoadModule mpm_event_module modules/mod_mpm_event.so

to

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

而且 Access rule 也有些修改

2.2 configuration:

Order deny,allow
Deny from all

2.4 configuration:

Require all denied

2.2 configuration:

Order allow,deny
Allow from all

2.4 configuration:

Require all granted
