We can view the log of any file or directory and see a list of all the files changed, added or deleted in any given revision. We can also view the differences between two versions of a file so as to see exactly what was changed in a particular revision. + +### Features ### + +WebSVN offers the following features: + +- Easy to use interface +- Customisable templating system +- Colourisation of file listings +- Blame view +- Log message searching +- RSS feed support +- [and more...][1] + +Since it's written using PHP, WebSVN is also very portable and easy to install. + +Now, we'll install WebSVN for our Subversion (Apache SVN). Make sure that you have installed Apache SVN in your server. If you don't have it installed, you can install from this tutorial. + +After you installed Apache SVN(Subversion), you'll need to follow the easy steps below. + +### 1. Download WebSVN ### + +You can download WebSVN from their official site http://www.websvn.info/download/ . We'll first get inside directory /var/www/html/ and then download the package inside it. + + $ sudo -s + +**Please execute the above command in a shell or terminal as wee'll need to switch to root privilege so that we'll have full access to the system's restricted areas.** + + # cd /var/www/html + # wget http://websvn.tigris.org/files/documents/1380/49057/websvn-2.3.3.zip + +![downloading websvn package](http://blog.linoxide.com/wp-content/uploads/2015/01/downloading-websvn.png) + +Here, I am download the latest version 2.3.3 of websvn. You can get the link from the site. You can simply replace the above link with the link of the package you wanna install. + +### 2. Extract the downloaded zip ### + + # unzip websvn-2.3.3.zip + + # mv websvn-2.3.3 websvn + +![extracting websvn](http://blog.linoxide.com/wp-content/uploads/2015/01/extracting-websvn.png) + +### 3. Install php ### + + # yum install php + +![yum install php](http://blog.linoxide.com/wp-content/uploads/2015/01/yum-install-php.png) + +### 4. Edit WebSVN config ### + +Now, we'll need to copy distconfig.php which is situated inside /var/www/html/websvn/include directory to config.php and then edit the configuration file. + + # cd /var/www/html/websvn/include + + # cp distconfig.php config.php + + # nano config.php + +Now, we'll need to make changes to the file as shown below.

Starting WebSVN ### + +Now, we are almost done. We now need to restart our Apache server. You can do that by the command below. + + # systemctl restart httpd.service + +And then, we'll open WebSVN inside our favorite browser with the address as http://Ip-address/websvn or if you are on local computer, you can goto http://localhost/websvn . + +![websvn successfully installed](http://blog.linoxide.com/wp-content/uploads/2015/01/websvn-success.png) + +**Note**: If you encountered error like "Unable to find "enscript" tool at location "/usr/bin/enscript"" then, you'll need to install enscript using the command "yum install enscript" which will fix the problem. + +### Conclusion ### + +Hurray, we have completed installing WebSVN in our CentOS 7 server. This tutorial works great on RHEL 7 too. WebSVN offers a view onto your subversion repositories that’s been designed to reflect the subversion methodology. You can view the log of any file or directory and see a list of all the files changed, added or deleted in any given revision.

It implements the Java Servlet, JavaServer Pages (JSP), Java Unified Expression Language and Java WebSocket specifications from Sun Microsystems and provides a web server environment for Java code to run in. + +Binding Tomcat to IPv4 is necessary if we have our server not working due to the default binding of our tomcat server to IPv6. As we know IPv6 is the modern way of assigning IP address to a device and is not in complete practice these days but may come into practice in soon future. So, currently we don't need to switch our tomcat server to IPv6 due to no use and we should bind it to IPv4. + +Before thinking to bind to IPv4, we should make sure that we've got tomcat installed in our CentOS 7. Here's is a quick tutorial on [how to install tomcat 8 in CentOS 7.0 Server][2]. + +### 1. Switching to user tomcat ### + +First of all, we'll gonna switch user to **tomcat** user. We can do that by running **su - tomcat** in a shell or terminal. + + # su - tomcat + +![Switch user to tomcat](http://blog.linoxide.com/wp-content/uploads/2015/01/switch-user-tomcat.png) + +### 2. Finding Catalina.sh ### + +Now, we'll First Go to bin directory inside the directory of Apache Tomcat installation which is usually under **/usr/share/apache-tomcat-8.0.x/bin/** where x is sub version of the Apache Tomcat Release. In my case, its **/usr/share/apache-tomcat-8.0.18/bin/** as I have version 8.0.18 installed in my CentOS 7 Server. + + $ cd /usr/share/apache-tomcat-8.0.18/bin + +**Note: Please replace 8.0.18 to the version of Apache Tomcat installed in your system. ** + +Inside the bin folder, there is a script file named catalina.sh . Thats the script file which we'll gonna edit and add a line of configuration which will bind tomcat to IPv4 . You can see that file by running **ls** into a terminal or shell. + + $ ls + +![finding catalina.sh](http://blog.linoxide.com/wp-content/uploads/2015/01/finding-catalina.sh_.png) + +### 3. Configuring Catalina.sh ### + +Now, we'll add **JAVA_OPTS= "$JAVA_OPTS -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses"** to that scripting file catalina.sh at the end of the file as shown in the figure below. We can edit the file using our favorite text editing software like nano, vim, etc. Here, we'll gonna use nano. + + $ nano catalina.sh + +![Catalina script](http://blog.linoxide.com/wp-content/uploads/2015/01/catalina-script.png) + +Then, add to the file as shown below: + +**JAVA_OPTS= "$JAVA_OPTS -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses"** + +![configured catalina](http://blog.linoxide.com/wp-content/uploads/2015/01/configured-catalina.png) + +Now, as we've added the configuration to the file, we'll now save and exit nano. + +### 4. Restarting ### + +Now, we'll restart our tomcat server to get our configuration working. We'll need to first execute shutdown.sh and then startup.sh . + + $ ./shutdown.sh + +Now, well run execute startup.sh as: + + $ ./startup.sh + +![restarting apache tomcat server](http://blog.linoxide.com/wp-content/uploads/2015/01/restarting-tomcat-server.png) + +This will restart our tomcat server and the configuration will be loaded which will ultimately bind the server to IPv4. + +### Conclusion ### + +Hurray, finally we'have got our tomcat server bind to IPv4 running in our CentOS 7 Linux Distribution. Binding to IPv4 is easy and is necessary if your Tomcat server is bind to IPv6 which will infact will make your tomcat server not working as IPv6 is not used these days and may come into practice in coming future.
