Installing Wt on CentOS5¶
- Installing Wt on CentOS5
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.
Install Wt dependencies¶
It was not my preference to install from source, however my yum setup did not recognize some of the packages.
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.
wget http://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
Install cmake from source
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
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
Wt will configure itself to use the build-in http server by default.
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.
cd ../examples/hello ../../build/examples/hello/hello.wt --docroot . --http-address 0.0.0.0 --http-port 8080
Type the following url into your web browser, substitute vm01 with localhost or the appropriate url.
*That's it. The rest of this document is provided for additional support. None of the steps below are required for basic Wt functionality
Some examples require additional dependencies to run properly.
yum install gd gd-devel
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
yum install mysql-devel
Build a binary rpm from source so it is specific for my platform
rpmbuild --rebuild http://tangentsoft.net/mysql++/releases/mysql++-3.0.8-1.src.rpm
Install the rpms. Note you may have to substitute <B>x86_64</B> for your platform
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
Deployment with FastCGI¶
See Deployment with FastCGI in page Installing Wt on Gentoo
Other Wt Examples¶
Hangman¶Hangman is a bit more difficult to run.
- Install the Mysql++ dependency
- Fix 'Result' compile error in hangman/HangmanDb.C
MySql++ type <B>Result</B> was renamed to <B>StoreQueryResult</B>. Replace all instances of 'Result' with 'StoreQueryResult'
- Rebuild Wt examples
- Make sure MySQL is running
service mysqld start
- Create the default hangman schema
mysql < dbscript
- Run hangman
cd ../examples/hangman ../../build/examples/hangman/hangman.wt --docroot . --http-address 0.0.0.0 --http-port 8080
cd ../examples/filetreetable ../../build/examples/filetreetable/filetreetable.wt --docroot . --http-address 0.0.0.0 --http-port 8080
Opening up port 8080¶
This is not requirement if you are view the examples from localhost.
If you get an error message like:
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.
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>
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
Restart iptables for the change to take effect.
