How to install JSVC on Linux WidenHome Log | WidenHome Log

In our team, we have a lot of Java standalone applications which should be run as daemon on Unix/Linux system, and we found JSVC is the best choice for us to wrap Java programs to daemons. This article records the steps on how to install JSVC executable on Linux, which is our stage/prod environment.

Download JSVC source package

First of all, we need to download JSVC source package from this URL:http://commons.apache.org/daemon/download_daemon.cgi, for example, I downloaded commons-daemon-1.0.5-src.tar.gz file. Or, download it via wget:

wget -c http://apache.etoak.com/commons/daemon/source/commons-daemon-1.0.5-src.tar.gz 

Build JSVC executable
Unzip the source package and build JSVC executable.

chmod 755 commons-daemon-1.0.5-src.tar.gz tar zxvf commons-daemon-1.0.5-src.tar.gz cd commons-daemon-1.0.5-src/src/native/unix 

Before building the JSVC executable, please make sure you have set JAVA_HOME variable correctly. And make sure you have “autoconf” and “make” installed, otherwise, install it by:

yum install autoconf yum install make 

After that, we can configure and make the JSVC executable now.

sh support/buildconf.sh ./configure --with-java=/opt/apps/jdk make clean make 

Eventually, move the “jsvc” to another folder and add that folder on PATH environment variable.

mv jsvc /opt/apps/commons-daemon vi ~/.bashrc 

Add two lines in .bashrc:

PATH=/opt/apps/commons-daemon:$PATH export PATH 

And then load the latest setting:

source ~/.bashrc

Now, we can use this command in script which will launch Java application as daemon.

Please make sure to add commons-daemon-x.jar into classpath, otherwise, we would see this error:

Cannot find daemon loader org/apache/commons/daemon/support/DaemonLoader Service exit with a return value of 1
