이 로그로 인해 Apache 가 정상적으로 응답하지 않는 현상도 발생한다

"Apache/2.4.41 (Ubuntu) mod_fcgid/2.3.9 OpenSSL/1.1.1f (internal dummy connection)" 더미 연결 로그 생성방지 해결방법은 아래와같다
1. RewriteEngine 을 이용한 로그방지
You can use .htaccess by redirecting requests from the "internal dummy connection" to an empty file
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^.*internal dummy connection.*$ [NC]
RewriteRule ^/$ /empty.html [L]
2. apache2.conf 설정에서 donot을 이용한 로그방지
해결책
/etc/apache2/apache2.conf
/etc/apache2/sites-enabled
두곳을 손봐야한다
1. apache2.conf 검정 밑줄친 부분을 추가해준다
LogFormat " %v %>s %h %l %u %t "%r" %>s %O "%{Referer}i" "%{User-Agent}i"" combined
LogFormat "%h %l %u %t "%r" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat " %v %>s "%{User-agent}i" agent
SetEnvIf Remote_Addr "127.0.0.1" dontlog
SetEnvIf Remote_Addr "::1" dontlog
SetEnvIf User-Agent ".*internal dummy connection.*" dontlog
LogFormat " %v %>s "%{User-Agent}i"" vhost_combined
2. /etc/apache2/sites-enabled 호스트안에 ****.log로 구분하여 로그기록을 하도록 분리한다.
<VirtualHost *:80>
CustomLog ${APACHE_LOG_DIR}/*****.log combined env=!dontlog
</VirtualHost>
