Now with the increase of production servers, I found that java based applications are particularly many, the system default comes with openjdk I am re-making kickstart, it is deleted, for jdk, our company's specified path is/usr/local/jdk, the company requires tar package to install...

For convenience, I think I'll make it an rpm package and put it in the/iso/media/Packages/directory of the system image, and configure the environment variables.

rpmbuild, for students who are not familiar with SPEC, it is difficult, so take a look at fpm this tool, packaging rpm is very convenient.

①yum installation related package

yum -y install ruby-devel ruby-rdoc

② Download rubygems

wget http://production.cf.rubygems.org/rubygems/rubygems-1.8.25.zip

Remove rubygems.

unzip rubygems-1.8.25.zip

④ Install ruby library

cd rubygems-1.8.25 && ruby setup.rb

Install fpm(slow, patient, etc.)

gem install fpm

I installed jdk under/usr/local/jdk

Run the following command directly from the root directory

fpm -s dir -a all -t rpm -n "jdk" -v 1.7.0.45 /usr/local/jdk

Okay, you'll see an rpm pack for jdk, everybody try it!!!

Supplement: If you encounter such an error

Need executable 'rpmbuild' to convert dir to rpm {:level=>:error}

Usually because you need to install rpmbuild

Yum -y install rpm-build can solve this problem

If you also need to execute the relevant initialization script after the regenerated rpm package, you can use the-post-install parameter

For example, I just installed a version 2.6 mongodb database with the source package

After I pack it, I hope that the startup script/etc/init.d/mongod I created can also be typed in.

Just write the script to the mongodb installation directory and use the--post-install parameter!

My mongodb directory is at/opt/mongodb, write an initialization script file

vi /opt/mongodb/postinstall
