CentOS the RPM package with the TAR source package

The company has a demand for encryption redis, there is a profile option Requirepass can set the password, but the company felt can be modified by the configuration file to disable the password, feel insecure, and then directly modify the source code (mandatory set Requirepass as a fixed password), The RPM package is perfectly safe.

1. Download the Redis source package

Http://redis.googlecode.com/files/redis-2.6.14.tar.gz

2. Modify the source code compilation

Tar zxvf redis-2.6.14.tar.gz

CD redis-2.6.14

Vim src/config.c

331 lines to delete, move to the Else statement after the end, whether it is not empty set Requirepass

Server.requirepass = Zstrdup ("123456"); #加到426行

Save exit, then compile

Make

\CP src/redis-server/usr/local/bin/
\CP src/redis-cli/usr/local/bin/

3. Make RPM Package

MV Redis-2.6.14.tar.gz/usr/src/redhat/sources

cd/usr/src/redhat/specs/

Vim Redis.spec

[Root@localhost specs]# Rpmbuild-ba Redis.spec

If there is no error in the operation, it is generated,/usr/src/redhat/srpms/redis-2.6.14-2.src.rpm and/usr/src/redhat/rpms/x86_64/redis-2.6.14-2.x86_64.rpm

Rpm-qpi redis-2.6.14-2.x86_64.rpm can view information about the package

Relocations: If Non-null, indicates that the package can be installed to the new directory. When installing the package, use--relocate=/usr/loca/=/home/cyx/to modify the installation location of the package.

It may not work, however, because the package is binary, and the absolute path may be used when the program compiles.

RPM package production is generated by Rpmbuild. Rpmbuild used a few directories:

Build RPMS SOURCES SPECS Srpms

Directory of Build:build Procedure execution

RPMS: Location of the last generated RPM package

SOURCES: Source file location

Specs:spec the location of the file, Rpmbuild to build the package using the description information of the spec file

Srpms: Source code RPM Package Location

Spec files are key files that instruct Rpmbuild to generate packages. Put it under the specs directory:

%description The following is a description of the package

Nginx-httpd-server

%prep Here's the prep work.

%setup-q Here we use the built-in command to solve the open source code package to the build directory.

%build Start building packages, corresponding to configure and make, in the build directory

Cflags= "-g"./configure

Make-j ' Cat/proc/cpuinfo | grep Processor | Wc-l '

%install Install package to BuildRoot

Make destdir= $RPM _build_root install

%files Finally, package the file into the RPM package, where you specify the files, permissions, and owners to be packaged, and the directory here is relative to the BuildRoot directory, but starts with '/'.

%defattr (755,daemon,daemon)

/usr/local/%{name}

%pre Perform the action here before installing the package with the RPM command

Echo Nginx,preinstall

%post Perform the action here after installing with the RPM command

Echo Nginx,afterinstall,done

%preun Perform the action here before uninstalling

Echo Nginx,uninstall

%postun Perform the action here after uninstalling

Echo Nginx,uninstall,done

---------------------------------------------End-----------------------------------------------------------------

So we can customize our RPM package.
