에러 발견!

root가 shell interpreter를 수행할 수 있는지 확인하기

# bin/sh

sh-3.2# exit

exit

#

OK!

permission 확인하기

#ls -ld /tmp/

drwxrwxrwx 17 root root 4096 Jun 18 07:41 /tmp/

OK!

mount 확인하기

# grep tmp /etc/fstab

LABEL=/tmp /tmp ext3 defaults,noexec,nodev,nosuid 1 2

tmpfs /dev/shm tmpfs defaults 0 0

이거다!

/tmp 는 'noexec' flag로 마운트가 되었다. 그래서 pecl로 xdebug를 설치할 때 실패했다.

그렇다면 pecl과 관련된 경로를 변경하자!

PEAR 경로 변경하기

# pear config-show | grep tmp

PEAR Installer download download_dir /tmp/pear/download

PEAR Installer temp directory temp_dir /tmp/

# pear config-set download_dir /root/tmp/pear/download

# pear config-set temp_dir /root/rmp

# pear config-show | grep tmp

PEAR Installer download        download_dir    /root/tmp/pear/download

PEAR Installer temp directory  temp_dir        /root/tmp/

OK!

Reinstall

# pecl install xdebug

여전히 에러가 난다!

# strace pecl install xdebug 2>&1

# cd /tmp && rm -fr pear pear-build-root

# ln -s /root/tmp/pear-build-root .     <= 마지막에 "." 이 있다!

# mkdir /root/tmp/pear-build-root

# pecl install xdebug

.

Build process completed successfully

Installing '/usr/lib64/php/modules/xdebug.so'

install ok: channel://pecl.php.net/xdebug-2.1.0

configuration option "php_ini" is not set to php.ini location

You should add "extension=xdebug.so" to php.ini

OK!

설치 확인해보기

# echo 'zend_extension="/usr/lib64/php/modules/xdebug.so"'  > /etc/php.d/xdebug.ini
# php -i | grep xdebug
/etc/php.d/xdebug.ini,
xdebug
.
.
.

OK!

module 추가하기

# vi /usr/local/apache/conf/php.ini
------------------>append<-----------------
extension=xdebug.so
---------------------------------------------
# service httpd restart

<?php phpinfo();?> 를 통해서 xdebug 모듈이 추가되었음을 확인할 수 있다.

xdebug 사용해보기

# vi /usr/local/apache/htdocs/xdebug_test.php
<?php
    function fix_string($a)
    {
        echo "Called @ ".
            xdebug_call_file().
            ":".
            xdebug_call_line().
            " from ".
            xdebug_call_function();
    }

    $ret = fix_string(array('Derick'));
?>

output 확인하기

go to http://your.ip.address/xdebug_test.php

return >
