How to solve the problem that the phpcms background CAPTCHA does not display in linux? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Website environment:

Linux CentOS

Php5.2.10

Apache 2.2.11

Zend Opt3.3.3

Reason:

Checkcode.php generates files in .jpg format, but phpinfo () does not show support for jpg format.

Solution:

1. Download jpegsrc.v6b.tar.gz and freetype-2.3.7.tar.gz files

2. Install:

Checking jpeg library [root@www download] # rpm-qa | grep jpeglibjpeg-devel-6b-43.fc10.i386libjpeg-6b-43.fc10.i386Install jpeg library [root@www download] # tar-zxvf jpegsrc.v6b.tar.gz [root@www download] # cd jpeg-6b [root@www jpeg-6b] #. / configure-- prefix=/usr/local/jpeg-- with-freetype=/usr/local/freetype-- enable-shared-enable-static [root@www jpeg-6b] # make [root@ Www jpeg-6b] # make intallChecking freetype library [root@www download] # rpm-qa | grep freetypefreetype-2.3.7-1.fc10.i386freetype-devel-2.3.7-1.fc10.i386Install freetype library [root@www download] # tar-zxvf freetype-2.3.7.tar.gz [root@www download] # cd freetype-2.3.7 [root@www freetype-2.3.7]. / configure-- prefix=/usr/local/freetype-- enable-shared-- Enable-static [root@www freetype-2.3.7] # make [root@www freetype-2.3.7] # make intall

3. Install php-5.2.10 now.

Enter the php source directory first.

# make#make install#cp php.ini-recommended / usr/local/php/etc/php.ini#echo AddType application/x-httpd-php .php > > / usr/local/apache2/conf/httpd.conf

Finally, based on the information returned by make install, the installation is completed.

You may want to add: / usr/local/php/lib/php to your php.ini include_path

Add the path to the include_path in the php.ini file and save it.

At this point, PHP is installed.

4. Check the phpinfo () file, and the returned result shows that gd supports jpeg format.

5. Install PHPCMS2008 SP2 again and enter the login screen in the background. Everything's fine.
