1, the production of RPM package Linux system environment

# Cat/etc/redhat-release

CentOS Release 5.8 (Final)

# Uname-r

2.6.18-308.el5

# uname-m

X86_64 2, pre-build the directory structure required to create Rpmbuild, usually installed cent0s5.8 system has created a directory structure, as follows:

# LS/USR/SRC

Debug Kernels Redhat

# ls/usr/src/redhat/

Build RPMS SOURCES SPECS Srpms root user to make RPM package use the directory under/usr/src/redhat/if you use ordinary users, you can create a good directory manually, the following command

# mkdir-p/home/zxp/{build,rpms,sources,specs,srpms} Directory Description : Build: The temporary storage space for the source code when compiling the software package.
RPMS: The output position of the prepared binary package.
SOURCES: The location of the source code.
The location where the specs:spec files are stored.
SRPMS: The output location of the source RPM package is produced, which still needs to be compiled before the package is installed. 3, spec file details to build a standard RPM package, you need to create a. spec file in the directory specs, which contains all the detailed information about the software that will be installed. Then execute the rpmbuild command on the text in the system, and the system will automatically generate the final RPM package according to the steps set by the. Spec content. 3.1 Spec file syntax (take Haproxy as an example)

%description #软件详细的描述信息

Ha-proxy is a tcp/http reverse Proxy which are particularly suited for high

Availability environments. Indeed, it can:

-Route HTTP requests depending on statically assigned cookies

-Spread the load among several servers while assuring server persistence

Through the use of HTTP cookies

-Switch to backup servers in the event a main one fails

-Accept connections to special ports dedicated to service monitoring

-Stop accepting connections without breaking existing ones

-Add/modify/delete HTTP headers both ways

-Block requests matching a particular pattern

It needs very little resource. It Event-driven architecture allows it to easily

Handle thousands of simultaneous connections on hundreds of instances without

Risking the system ' s stability.

-Initial build 3, get the Spec file method (three methods) 3.1 Method 1: Get download & install the corresponding SRC.RPM package via SRC.RPM Package

# CD srpms/

# wget http://1wt.eu/tools/haproxy/src/devel/haproxy-1.2.3-1.src.rpm

# RPM-IVH haproxy-1.2.3-1.src.rpm

# ls/usr/src/redhat/{sources,specs}

# ls

Now that the custom RPM package has been produced, we can then use the Common application software source package to be made into the Yum warehouse, the future deployment of software is very convenient. To continue, please move to the "Add custom RPM package to the internal Yum Sever" http://dreamway.blog.51cto.com/blog/1281816/1110874
