h1. Installing Wt on CentOS5 

 {{toc}} 

 The purpose of this page is to provide information on how to install Wt on CentOS5.2. As a special note, I am installing to a XEN domU instance, however I believe any CentOS5.2 install will work the same. I was logged in as root through the duration of this install. This document was originally adapted from [[Installing Wt on Fedora Core]].

 h2. Install Wt dependencies  


 h3. Required dependencies  

 It was not my preference to install from source, however my yum setup did not recognize some of the packages. 


 h4. Boost  

 Boost is installed by hand so we can build the multi-threaded libraries. If you use 'yum install boost boost-devel' you will run into problems running some of the examples. So I recommend installing it by hand. 

 <pre> 
 wget http://internap.dl.sourceforge.net/sourceforge/boost/boost_1_37_0.tar.gz 
 tar zxvf boost_1_37_0.tar.gz 
 cd boost_1_37_0/ 
 ./configure --with-libraries=thread,regex,program_options,date_time,signals,system,filesystem 
 make install 
 </pre> 


 h4. CMAKE  

 Install cmake from source 
 <pre> 
 wget http://www.cmake.org/files/v2.6/cmake-2.6.2.tar.gz 
 tar zxvf cmake-2.6.2.tar.gz 
 cd cmake-2.6.2 
 ./bootstrap; make; make install 
 </pre> 


 h2. Building Wt  

 <pre> 
 wget http://internap.dl.sourceforge.net/sourceforge/witty/wt-2.2.2.tar.gz 
 tar zxvf wt-2.2.2.tar.gz 
 cd wt-2.2.2 
 mkdir build 
 cd build 

 # make sure you substitute your version of boost and gcc into this statement 
 cmake -DBOOST_DIR=/usr/local -DBOOST_VERSION=1_37 -DBOOST_COMPILER=gcc41 .. 
 make 
 make -C examples 
 make install 
 </pre> 

 Wt will configure itself to use the build-in http server by default. 


 h2. Running the Examples provided  

 This section covers how to run the hello example. Other examples may be run in a similar manner. Some examples may require additional dependencies to be setup. 


 h3. Running Hello  

 <pre> 
 cd ../examples/hello 
 ../../build/examples/hello/hello.wt --docroot . --http-address 0.0.0.0 --http-port 8080 
 </pre> 

 Type the following url into your web browser, substitute vm01 with localhost or the appropriate url. 

 http://vm01:8080/ 

 *That's it. The rest of this document is provided for additional support. None of the steps below are required for basic Wt functionality 


 h2. Optional dependencies  

 Some examples require additional dependencies to run properly. 


 h3. Installing GD  

 <pre> 
 yum install gd gd-devel 
 </pre> 


 h3. Installing MySQL++  

 There has got to be a better way! This does seem to work though. I chose a source rpm so it would be built for x86_64 platform, your architecture may be named differently. 

 Install mysql development libraries 
 <pre> 
 yum install mysql-devel 
 </pre> 

 Build a binary rpm from source so it is specific for my platform 
 <pre> 
 rpmbuild --rebuild http://tangentsoft.net/mysql++/releases/mysql++-3.0.8-1.src.rpm 
 </pre> 

 Install the rpms. Note you may have to substitute <B>x86_64</B> for your platform 
 <pre> 
 cd /usr/src/redhat/RPMS/x86_64 
 rpm -i mysql++-3.0.8-1.x86_64.rpm 
 rpm -i mysql++-debuginfo-3.0.8-1.x86_64.rpm 
 rpm -i mysql++-devel-3.0.8-1.x86_64.rpm 
 rpm -i mysql++-manuals-3.0.8-1.x86_64.rpm 
 </pre> 


 h2. Deployment with FastCGI  

 See Deployment with FastCGI in page [[Installing Wt on Gentoo]] 


 h2. Other Wt Examples  


 h3. Hangman  

 Hangman is a bit more difficult to run.  
 * Install the Mysql++ dependency 

 * Fix 'Result' compile error in hangman/HangmanDb.C 
 <pre> 
      MySql++ type <B>Result</B> was renamed to <B>StoreQueryResult</B>. 
      Replace all instances of 'Result' with 'StoreQueryResult' 
 </pre> 

 * Rebuild Wt examples 

 * Make sure MySQL is running 
 <pre> 
 service mysqld start 
 </pre> 

 * Create the default hangman schema 
 <pre> 
 mysql < dbscript 
 </pre> 

 * Run hangman 
 <pre> 
 cd ../examples/hangman 
 ../../build/examples/hangman/hangman.wt --docroot . --http-address 0.0.0.0 --http-port 8080 
 </pre> 


 h3. Filetreetable  

 <pre> 
 cd ../examples/filetreetable 
 ../../build/examples/filetreetable/filetreetable.wt --docroot . --http-address 0.0.0.0 --http-port 8080 
 </pre> 


 h2. Trouble shooting  


 h3. Opening up port 8080  

 This is not requirement if you are view the examples from localhost. 

 If you get an error message like: 
 <pre> 
 Failed to Connect 

 Firefox can't establish a connection to the server at vm01:8080.     

 Though the site seems valid, the browser was unable to establish a connection. 
 </pre> 

 This message may mean you need to open up port 8080. If you wish to access port 8080 remotely then add the following rule to file <B>/etc/sysconfig/iptables</B> 
 <pre> 
 -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT 
 </pre> 

 Restart iptables for the change to take effect. 
 <pre> 
 /etc/init.d/iptables restart
