Jexus Series: How to Upgrade Jexus on Ubuntu

In last post we discussed how to install Jexus on a clean Ubuntu 13.04 machine. Here we discuss how to upgrade from Jexus 5.2 to 5.3.1.

What is Jexus?

Jexus Web Server is a free web server for Linux (it is free, but not open source). It is powered by Mono and aims to provide best support for ASP.NET applications (while it also provides excellent PHP support out of the box).

Its homepage is at http://www.linuxdot.net/ (in Simplified Chinese).

Upgrade Steps

1. Download and unpack Jexus

   wget http://www.linuxdot.net/down/jexus-5.3.1.tar.gz
   tar -zxvf jexus-5.3.1.tar.gz
   

   Jexus binary package is downloaded from its official site, and extracted to a folder named jexus-5.3.1 after this step.

2. Stop current Jexus 5.2 server,

   cd /usr/jexus
   sudo ./jws.stop
   

   Assume the previous release was installed at /usr/jexus, we stop the service.

3. Copy new files to Jexus folder

   cd ~/jexus-5.3.1
   sudo ./upgrade
   

   Now let’s go back to the extracted folder and upgrade necessary files to /usr/jexus.

4. Fix startup commands

   sudo vi /etc/rc.local
   

   Press i on keyboard to enter edit mode.

   Replace previous start command /usr/jexus/jws.start with /usr/jexus/jws start.

   Remove /usr/jexus/state.start if it presents.

   Press Esc on keyboard to exit edit mode.

   Type :wq and press Enter on keyboard to exit vi.

   Here we remove the old entries, and use a new entry to start Jexus at startup.

5. Start Jexus HTTP service

   cd /usr/jexus
   sudo ./jws start
