 3월 08 17:11:50 lukehan apachectl[3639124]: AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

Apache2 재구동 시 위와 같은 메시지가 발생하였다.

 

특별한 이상 증상은 없으나 불필요한 메시지를 나오지 않도록 수정 진행 하였다.

 

 

 

 

lukehan@lukehan:~$ grep ServerName /etc/apache2/apache2.conf
lukehan@lukehan:~$

 

ServerName 이 설정되지 않은 것을 확인할 수 있다.

 

 

 

 

lukehan@lukehan:~$ ech "ServerName localhost" >> /etc/apache2/apache2.conf

lukehan@lukehan:~$ grep ServerName /etc/apache2/apache2.conf
ServerName localhost

 

위와 같이 추가된 것을 확인할 수 있다.

 

 

 

 

lukehan@lukehan:~$ sudo service apache2 restart

 

변경 설정이 반영되도록 Apache2 를 재구동 한다.
