gd library가 있는데도 PHP에서 문제가 발생하였다.
1. PHP 정보 확인
– info.php파일을 만들어 확인결과 gd 라이브러리가 안 올라옴.
$ cat info.php
<?php
phpinfo();
?>
2. error 정보를 보기 위해 /etc/php5/apache2/php.ini파일을 수정
$ diff php.ini.bak php.ini
344c344
< log_errors = Off
—
> log_errors = On
390c390
< ;error_log = filename
—
> error_log = /var/log/php.txt
3. apache 재시작 및 log파일 확인
$ sudo /etc/init.d/apache2 restart
$ cat /var/log/php.txt

4. php -m 명령으로 모듈 확인
$ php -m

5. 라이브러리 확인
$ nm -D /usr/lib/php5/20060613+lfs/gd.so |grep gdImageCreateFromJpeg
U gdImageCreateFromJpeg
U gdImageCreateFromJpegCtx
$ nm -D /usr/lib/libgd.so.2 |grep gdImageCreateFromJpeg

libgd.so없는 경우 설치
$ apt-get install libgd2-xpm-dev
6. 라이브러리 위치 확인
$ ldd /usr/lib/php5/20060613+lfs/gd.so

7. libgd위치 확인 결과 /usr/local/lib과 /usr/lib에 다른 버전이 있었음.
$ locate libgd (위치 확인)
…
$ cd /usr/local/lib
$ sudo mkdir libgd.backup
$ sudo mv libgd.so* libgd.backup
$ sudo /etc/init.d/apache2 restart
8 . 정상동작 확인
$ php -m
