<title>Building RPMs</title>
|
||||
<para>
|
||||
While we have defined, and you have presumably already installed the
|
||||
bootstrap prerequisites, there are a number of build time prerequisites
|
||||
that need to be resolved. &PRODUCT; uses maven for dependency resolution.
|
||||
You can resolve the buildtime depdencies for CloudStack by running the
|
||||
following command:
|
||||
<programlisting><prompt>$</prompt> <command>mvn</command> -P deps</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
Now that we have resolved the dependencies we can move on to building &PRODUCT;
|
||||
and packaging them into RPMs by issuing the following command.
|
||||
<programlisting><prompt>$</prompt> <command>./waf</command> rpm</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
Once this completes, you should find assembled RPMs in
|
||||
<filename>artifacts/rpmbuild/RPMS/x86_64</filename>
|
||||
</para>
|
||||
<section id="sect-source-buildrpm-repo">
|
||||
<title>Creating a yum repo</title>
|
||||
<para>
|
||||
While RPMs is an ideal packaging format - it's most easily consumed from
|
||||
yum repositories over a network. We'll move into the directory with the
|
||||
newly created RPMs by issuing the following command:
|
||||
<programlisting><prompt>$</prompt> <command>cd</command> artifacts/rpmbuild/RPMS/x86_64</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
Next we'll issue a command to create the repository metadata by
|
||||
issuing the following command:
|
||||
<programlisting><prompt>$</prompt> <command>createrepo</command> ./</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
The files and directories within our current working directory can now
|
||||
be uploaded to a web server and serve as a yum repository
|
||||
</para>
|
||||
<title>Building RPMs from Source</title>
|
||||
<para>As mentioned previously in <xref linkend="sect-source-prereq" />, you will need to install several prerequisites before you can build packages for &PRODUCT;. Here we'll assume you're working with a 64-bit build of CentOS or Red Hat Enterprise Linux.</para>
|
||||
<para><programlisting># yum groupinstall "Development Tools"</programlisting></para>
|
||||
<para><programlisting># yum install java-1.6.0-openjdk-devel.x86_64 genisoimage mysql mysql-server ws-common-utils MySQL-python tomcat6 createrepo</programlisting></para>
|
||||
<para>Next, you'll need to install build-time dependencies for CloudStack with
|
||||
Maven. We're using Maven 3, so you'll want to
|
||||
<ulink url="http://maven.apache.org/download.cgi">grab a Maven 3 tarball</ulink>
|
||||
and uncompress it in your home directory (or whatever location you prefer):</para>
|
||||
<para><programlisting>$ tar zxvf apache-maven-3.0.4-bin.tar.gz</programlisting></para>
|
||||
<para><programlisting>$ export PATH=/usr/local/apache-maven-3.0.4//bin:$PATH</programlisting></para>
|
||||
<para>Maven also needs to know where Java is, and expects the JAVA_HOME environment
|
||||
variable to be set:</para>
|
||||
<para><programlisting>$ export JAVA_HOME=/usr/lib/jvm/jre-1.6.0-openjdk.x86_64/</programlisting></para>
|
||||
<para>Verify that Maven is installed correctly:</para>
|
||||
<para><programlisting>$ mvn --version</programlisting></para>
|
||||
<para>You probably want to ensure that your environment variables will survive a logout/reboot.
|
||||
Be sure to update <filename>~/.bashrc</filename> with the PATH and JAVA_HOME variables.</para>
|
||||
|
||||
<para>Building RPMs for $PRODUCT; is fairly simple. Assuming you already have the source downloaded and have uncompressed the tarball into a local directory, you're going to be able to generate packages in just a few minutes.</para>
|
||||
<note><title>Packaging has Changed</title>
|
||||
<para>If you've created packages for $PRODUCT; previously, you should be aware that the process has changed considerably since the project has moved to using Apache Maven. Please be sure to follow the steps in this section closely.</para>
|
||||
</note>
|
||||
<section id="generating-rpms">
|
||||
<title>Generating RPMS</title>
|
||||
<para>Now that we have the prerequisites and source, you will cd to the <filename>packaging/centos63/</filename> directory.</para>
|
||||
<para>Generating RPMs is done using the <filename>package.sh</filename> script:
|
||||
<programlisting><prompt>$</prompt>./package.sh</programlisting>
|
||||
</para>
|
||||
<para>That will run for a bit and then place the finished packages in <filename>dist/rpmbuild/RPMS/x86_64/</filename>.</para>
|
||||
<para>You should see seven RPMs in that directory: <filename>cloudstack-agent-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, <filename>cloudstack-awsapi-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, <filename>cloudstack-cli-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, <filename>cloudstack-common-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, <filename>cloudstack-docs-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, <filename>cloudstack-management-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>, and <filename>cloudstack-usage-4.1.0-SNAPSHOT.el6.x86_64.rpm</filename>.</para>

<section id="sect-source-buildrpm-repo">

<title>Creating a yum repo</title>
|
||||
<para>
|
||||
While RPMs is a useful packaging format - it's most easily consumed from Yum repositories over a network. The next step is to create a Yum Repo with the finished packages:
|
||||
<programlisting><prompt>$</prompt> mkdir -p ~/tmp/repo</programlisting>
|
||||
<programlisting><prompt>$</prompt> cp dist/rpmbuild/RPMS/x86_64/*rpm ~/tmp/repo/</programlisting>
|
||||
<programlisting><prompt>$</prompt> createrepo ~/tmp/repo</programlisting>
|
||||
</para>
|
||||
<para>
|
||||
The files and directories within <filename>~/tmp/repo</filename> can now be uploaded to a web server and serve as a yum repository.
|

</para>

||||
<section id="sect-source-buildrpm-repo2">
|

<title>Configuring your systems to use your new yum repository</title>
|
||||
<para>
|
||||
Now that your yum repository is populated with RPMs and metadata
|
||||
we need to configure the machines that need to install $PRODUCT;.
|

Create a file named <filename>/etc/yum.repos.d/cloudstack.repo</filename> with this information:
