In CentOS 7.3, how does one create an rpm file ?, Centosrpm

Take a general disk detection software sas3ircu as an example to see how to package a binary file into an rpm file and then run rpm-ivh xxx. rpm installs the rpm file to the system.

CentOS 7.3 is used. The steps are as follows:

Step 1. install three necessary rpm package production software

    yum install rpm-build    yum install rpmrebuild    yum install rpmdevtools

Step 2. Run the command to generate the rpmbuild directory in the current directory

This directory is the directory required by the rpm-build command in the future during rpm packaging.

    rpmdev-setuptree 

The internal structure of the rpmbuild directory is as follows:

rpmbuild/├── BUILD├── RPMS├── SOURCES├── SPECS└── SRPMS

Step 3. Write a makefile

    DESTDIR=    dirname=$(DESTDIR)/usr/bin    install : sas3ircu        test -d $(dirname) || mkdir -p $(dirname)        cp sas3ircu $(DESTDIR)/usr/bin/sas3ircu    .PHONY : clean    clean :         rm -f sas3ircu

Step 4. Write a spec File

    Name: sas3ircu    Version: 16.0.0    Release: 1    Summary: sas3ircu is a disk check utility    Group:  Applications/Engineering    License: N/A    Source0: %{name}-%{version}.tar.gz    %description    This is a disk check utility.    %define debug_package %{nil}    %prep    %setup    %build    make    %install    echo ${RPM_BUILD_ROOT}    make DESTDIR=${RPM_BUILD_ROOT} install    %files    %defattr(-,root,root)    /usr/bin/%(name)

Step 5. view the directory structure in rpmbuild

    .    ├── BUILD    ├── BUILDROOT    ├── RPMS    ├── SOURCES    │   └── sas3ircu-16.0.0    │       ├── makefile    │       └── sas3ircu    ├── SPECS    │   └── sas3ircu.spec    └── SRPMS        └── sas3ircu-16.0.0-1.src.rpm

Step 6. Package the content in the SOURCES folder into a sas3ircu-16.0.0.tar.gz

cd SOURCEStar -cf sas3ircu-16.0.0.tar sas3ircu-16.0.0/gzip sas3ircu-16.0.0.tarrm -rf sas3ircu-16.0.0

The directory structure of rpmbuild is as follows:

    .    ├── BUILD    ├── BUILDROOT    ├── RPMS    ├── SOURCES    │   └── sas3ircu-16.0.0.tar.gz    ├── SPECS    │   └── sas3ircu.spec    └── SRPMS

Step 7. Create an rpm package

    rpmbuild -bb ./rpmbuild/SPECS/sas3ircu.spec

Note that the-ba option is used when a source file exists. If no source file exists, only the binary file is used. You can use the-bb option.

The Command Execution returns the following:

    [root@host-72 ~]# rpmbuild -bb ./rpmbuild/SPECS/sas3ircu.spec    sh: name: command not found    Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.XhQG2P    + umask 022    + cd /root/rpmbuild/BUILD    + cd /root/rpmbuild/BUILD    + rm -rf sas3ircu-16.0.0    + /usr/bin/gzip -dc /root/rpmbuild/SOURCES/sas3ircu-16.0.0.tar.gz    + /usr/bin/tar -xvvf -    drwxrwxr-x finix/finix       0 2018-02-09 21:36 sas3ircu-16.0.0/    -rw-rw-r-- finix/finix     182 2018-02-09 21:31 sas3ircu-16.0.0/makefile    -rwxr-xr-x finix/finix  660560 2018-02-09 15:36 sas3ircu-16.0.0/sas3ircu    + STATUS=0    + '[' 0 -ne 0 ']'    + cd sas3ircu-16.0.0    + /usr/bin/chmod -Rf a+rX,u+w,g-w,o-w .    + exit 0    Executing(%build): /bin/sh -e /var/tmp/rpm-tmp.oAnm6z    + umask 022    + cd /root/rpmbuild/BUILD    + cd sas3ircu-16.0.0    + make    test -d /usr/bin || mkdir -p /usr/bin    cp sas3ircu /usr/bin/sas3ircu    + exit 0    Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.FCXhbk    + umask 022    + cd /root/rpmbuild/BUILD    + '[' /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64 '!=' / ']'    + rm -rf /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    ++ dirname /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    + mkdir -p /root/rpmbuild/BUILDROOT    + mkdir /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    + cd sas3ircu-16.0.0    + echo /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    + make DESTDIR=/root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64 install    test -d /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64/usr/bin || mkdir -p /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64/usr/bin    cp sas3ircu /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64/usr/bin/sas3ircu    + /usr/lib/rpm/check-buildroot    + /usr/lib/rpm/redhat/brp-compress    + /usr/lib/rpm/redhat/brp-strip /usr/bin/strip    + /usr/lib/rpm/redhat/brp-strip-comment-note /usr/bin/strip /usr/bin/objdump    + /usr/lib/rpm/redhat/brp-strip-static-archive /usr/bin/strip    + /usr/lib/rpm/brp-python-bytecompile /usr/bin/python 1    + /usr/lib/rpm/redhat/brp-python-hardlink    + /usr/lib/rpm/redhat/brp-java-repack-jars    Processing files: sas3ircu-16.0.0-1.x86_64    warning: File listed twice: /usr/bin    Provides: sas3ircu = 16.0.0-1 sas3ircu(x86-64) = 16.0.0-1    Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(FileDigests) <= 4.6.0-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1    Checking for unpackaged file(s): /usr/lib/rpm/check-files /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    Wrote: /root/rpmbuild/RPMS/x86_64/sas3ircu-16.0.0-1.x86_64.rpm    Executing(%clean): /bin/sh -e /var/tmp/rpm-tmp.kKDpcQ    + umask 022    + cd /root/rpmbuild/BUILD    + cd sas3ircu-16.0.0    + /usr/bin/rm -rf /root/rpmbuild/BUILDROOT/sas3ircu-16.0.0-1.x86_64    + exit 0

Step 8. Check whether the rpm package is generated

[root@host-72 ~]# tree rpmbuild/rpmbuild/├── BUILD│   └── sas3ircu-16.0.0│       ├── makefile│       └── sas3ircu├── BUILDROOT├── RPMS│   └── x86_64│       └── sas3ircu-16.0.0-1.x86_64.rpm├── SOURCES│   └── sas3ircu-16.0.0.tar.gz├── SPECS│   └── sas3ircu.spec└── SRPMS

Step 9. Verify that the generated rpm package can be installed

First, delete the sas3ircu file that has been copied to the/usr/bin directory: rm-f/usr/bin/sas3ircu
Then, install the rpm file:

    [root@host-72 ~]# rpm -ivh ./rpmbuild/RPMS/x86_64/sas3ircu-16.0.0-1.x86_64.rpm     Preparing...                          ################################# [100%]        package sas3ircu-16.0.0-1.x86_64 is already installed        file / from install of sas3ircu-16.0.0-1.x86_64 conflicts with file from package filesystem-3.2-21.el7.x86_64        file /usr/bin from install of sas3ircu-16.0.0-1.x86_64 conflicts with file from package filesystem-3.2-21.el7.x86_64

The above error is found. What should we do? Google.

Step 10. resolve the conflict

rpmrebuild -pe ./rpmbuild/RPMS/x86_64/sas3ircu-16.0.0-1.x86_64.rpm 

After this command is run, an editor (such as vi) will be opened for you to edit the SPEC content. The following sentence will be displayed: Delete the sentence and exit:

    # Delete this line    %dir %attr(0755, root, root) "/usr/bin"

Step 11. Verify again

First, delete the remaining rpm parts that have been installed in Step 9. Then, repeat Step 9 to verify that the rpm file can be successfully installed.

    [root@host-72 ~]# rpm -e sas3ircu     [root@host-72 ~]# rpm -ivh ./rpmbuild/RPMS/x86_64/sas3ircu-16.0.0-1.x86_64.rpm     Preparing...                          ################################# [100%]    Updating / installing...       1:sas3ircu-16.0.0-1                ################################# [100%]    [root@host-72 ~]# ls -l /usr/bin/sas3ircu     -rwxr-xr-x 1 root root 658632 Feb  9 21:42 /usr/bin/sas3ircu

This indicates that the installation is successful and the rpm is available.

Finally, the syntax for SPEC files is complex. If necessary, you need to study more on your own.
