The Centos system USES mock to build rpm methods

preface

Execute under centos rpmbuild -ba package.spec It is common to require the system to install dependent packages as well, which can result in the system being loaded with useless software packages and taking up space. So we searched 1, and we found that we could pass mock Command to solve the problem.

Building methods

The first is installation mock Because of mock Is in the epel It's in the warehouse, so it needs to be loaded first epel warehouse

yum -y install epel-release
yum -y install mock

Usually used rpmbuild It will open a new user, for example builder So as not to pollute the system. We need to put builder Users join mock User groups

usermod -a -G mock builder

mock use rebuild You need the src.rpm file, so if you only have the.spec file, you need the src.rpm file

rpmbuild -bs package.spec

This will generate an src.rpm file in the SRPM directory, and it will pass through mock Command to rebuild rpm file

You need to initialize first mock Environment. In the /etc/mock folder, there are configuration files for various environments. For example, centos 6 is epel-6-x86_64, and the initialization command is:

mock -r epel-6-x86_64 --init

Once the initialization is complete, the build can begin

mock -r epel-6-x86_64 rebuild package-1.1-1.src.rpm

When the build is complete, rpm Files are stored in/var lib mock/epel - 6 - x86_64 / result directory. Of course we can �resultdir Parameter to specify rpm The generated directory of the file

mock -r epel-6-x86_64 rebuild package-1.1-1.src.rpm --resultdir=/home/builder/rpms

The last execution clean Command clean up the environment

mock -r epel-6-x86_64 --clean

conclusion

The above is all about building rpm with mock under Centos. I hope the content of this paper can bring you some help in your study or work. If you have any questions, you can leave a message to communicate.
