Linux Installing APR and Tomcat Native Library on Tomcat 7.0

Key notes:

  1. The objective: install APR and Tomcat Native Library on Tomcat 7.0.41.  I am using Icetea java 1.6 open JDK as when I download JAVA from Oracle, it has rt.jar missing on 1.6 and 1.7
  2. The linux platform is RHEL 6.3
  3. I download and compile tar source of APR (1.5) and APR util (1.5.3).  I found that when I use yum install, the apr library is incompleted.
  4. Need to yum install java openjdk.  I am using 1.6.
  5. Untar APR and follow readme to configure and compile.  make && make install
  6. Follow this (Eng) and this (S.Chi) to configure, compile and install Tomcat Native Library
  7. The command I use is: ./configure --with-apr=/usr/local/apr --with-java-home=/usr/lib/jvm/java-openjdk/
  8. In setenv.sh (under <tomcat_dir>/bin, if not exists, create one), I set the following: 
    1. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
    2. JAVA_HOME=/usr/lib/jvm/java-openjdk
    3. CLASSPATH=$CLASSPATH:/usr/local/tomcat7/webapps/
    4. CATALINA_OPTS="-server -Xms6G -Xmx6G $CATALINA_OPTS -XX:+UseConcMarkSweepGC -XX:+UseParNewGC"
  9. Notice in LD_LIBRARY_PATH, you need to "define the path of APR", but this sentence is misleading.  What you really need is to "define the lib path of APR", so it is /usr/local/apr/lib, not /usr/local/apr
  10. Restart tomcat and you should be fine.

TCPDF How to show/display Chinese Character?

Thanks to this article (in Simplified Chinese, updated new link), there is a way to embed a TTF that can display Chinese (Traditional and Simplify, and possibly Japanese). Environment:  TCPDF 6.0.020 PHP 5.3.8 Windows 7 The problem: If you follow this post that said: using cid0cs or cid0ct to display Chinese, it can display the character correctly, only to the extend that user installed a correct font package.  However, chances are other users who didn't install that package cannot view that PDF since there are several packages and versions of PDF viewer (mainly Adobe).  And even worse: even if user installed certain CJK font package, the PDF still not displayed correctly (show empty page). And according to the official TCPDF documentation about font : The fonts that could be not embedded are only the standard core fonts and CID-0 fonts . The solution: Again, thanks to the post above (in simplified Chinese), now developer can use a font that: Can disp...

How to fix fancy box/Easy Fancybox scroll not work in mobile

Hi The Problem: If you are working on EasyFancybox or just normal fancybox JS , and you have this problem: In your iOS device when a popup is opened, if the page is too wide and your pop up cannot show all, when user taps and drag the screen, the background will be dragged instead of the pop-up content. To fix, add this in your CSS: -webkit-overflow-scrolling: touch !important; So which element should you apply it to? In Easy Fancybox, you will see these 2 lines: <div id="fancybox-content"........>         <iframe id="fancybox-frame" name............... Apply to fancybox-content, not fancybox-frame So in your CSS, it should be: #fancybox-content{         overflow: scroll !important;         -webkit-overflow-scrolling: touch !important; } It works for me, and I hope it helps someone also.

Wordpress Load balancing: 2 web servers 1 MySQL without any Cloud services

Image
This is the exact config that I need to configure a load balancing without other cloud services like Amazon, rackspace or GoGrid, completely customized. I put my question on stackoverflow.com but no luck, so I put it on Quora.com and immediately I got response: My Notes: The load balancer is done by my colleagues so I am not sure what is the config of it.  But one thing to note: Your LB should enable "session stickiness" so that the session will follow visitor.  By the way, I am using Round-robins. Session: Actually I did not use session, but it seems that other plugins (like WPML) will use it.  If I use Apache load balancer, when I go to wp-admin through load balancing IP, I will not able to login, given the username and password is the same.  I will be redirected to login page.  So ask your load balancer providers or check your load balancer config and see how to manage the "Session Stickiness" issue. Shared folder: your wp-content/uploads folder...
