리눅스 방화벽 설정하기

IP주소 확인하기
[root@localhost ~]# ip addr

link/ether 00:0c:29:a3:8a:1c brd ff:ff:ff:ff:ff:ff
inet 192.168.88.129/24 brd 192.168.88.255 scope global noprefixroute dynamic ens33 valid_lft 1655sec preferred_lft 1655sec

크롬브라우저에 리눅스서버 IP를 넣어서 정상적으로 웹서버가 되는지 결과를 확인한다.
http://192.168.88.129

 

결과가 만약에 정상적인 페이지가 나오지 않을때의 해결법

[1]PHP 설치가 제대로 되어 있지 않음

[root@localhost ~]# yum -y install php

[2]<? ?>를 인식하지 않음

두번째 것은 php.ini를 수정해야 합니다. short_open_tag를 활성화 시키셔야 합니다.

[root@localhost ~]# vi /etc/php.ini

short_open_tag = On;

만일 PHP가 설치 되어 있는데 위의 코드가 실행되지 않는다면 간단히 다음과 같은 소스로 테스트 해보겠다.

<?php echo "Testing<br/>"; ?>
