This article mainly shares with you the RPM packaging process under Linux, hoping to help everyone.

Preparation before starting

Install rpmbuild software package

  • yum -y install rpm-build

    Generate related directories

To generate rpm-related directories, you can create them manually or through the rpmbuild command. For example: 

[root@yang data]# rpmbuild zabbix_agentd_ops.spec 
error: File /root/rpmbuild/SOURCES/zabbix-3.0.3.tar.gz: No such file or directory

有报错，无需理会，可以看到rpmbuild目录已经创建完成

[root@yang ~]# tree rpmbuild/
rpmbuild/
├── BUILD
├── BUILDROOT
├── RPMS
├── SOURCES
├── SPECS
└── SRPMS

Write SPEC file

SPEC keyword

Name: The name of the software package, which can be referenced later using %{name}

Summary: Summary of the contents of the software package

Version: The actual version number of the software, for example: 1.0.1, etc., which can be referenced later using %{version}

Release: Release serial number, for example: 1linuxing, etc., indicate the number of times to package, you can use %{release} to reference later

Group: Software grouping, it is recommended to use standard grouping

License: Software authorization method, usually GPL

Source: Source code package, you can bring multiple sources such as Source1, Source2, etc., and you can also use %{source1}, %{source2} later to reference

BuildRoot: This is used during installation or compilation "Virtual directory", considering the multi-user environment, is generally defined as: %{tmppath}/{name}-%{version}-%{release}-root or %{tmppath}/%{name}-%{version }-%{release}-buildroot-%%__id_u} -n}. This parameter is very important because during the process of generating rpm, the software will be installed into the above path when executing make install. When packaging, It also relies on the "virtual directory" to be the "root directory" for operations. It can be referenced later using the $RPM_BUILD_ROOT method.

URL: Home page of the software

Vendor: Publisher or packaging organization information, such as RedFlag Co,Ltd

Disstribution: Distribution identification

Patch : Patch source code, you can use Patch1, Patch2, etc. to identify multiple patches, use %patch0 or %{patch0} to reference

Prefix: %{_prefix} This is mainly to solve the problem that when installing rpm packages in the future, it will not necessarily Install the software into the directory packaged in rpm. In this way, the identifier must be defined here and referenced when writing the %install script to realize the function of re-specifying the location during rpm installation

Prefix: %{sysconfdir} This reason is the same as above, but because %{prefix} refers to /usr, and for other files, such as configuration files under /etc, you need to use %{_sysconfdir} to identify

Build Arch: refers to the target processor architecture for compilation, and the noarch indicator does not Specified, but usually the content in /usr/lib/rpm/marcros is used as the default value

Requires: The name of the software package that the rpm package depends on. You can use >= or <= to indicate greater than Or less than a specific version, for example: libpng-devel >= 1.0.20 zlib ※ The ">=" sign needs to be separated by spaces, and different software names are also separated by spaces, as well as PreReq, Requires (pre ), Requires(post), Requires(preun), Requires(postun), BuildRequires, etc. are all specified for dependencies at different stages

Provides: Indicate some specific functions of this software so that other rpm can identify them

Packager: Packager’s information

%description Detailed description of the software

SPEC script body

%prep Preprocessing script

%setup - n %{name}-%{version}** Unzip and put the source code package, usually from the package in /usr/src/asianux/SOURCES to /usr/src/asianux/BUILD/%{name}-% {version}. Generally, %setup -c is enough, but there are two situations: one is to compile multiple source code packages at the same time, and the other is that the name of the source code tar package is inconsistent with the decompressed directory. In this case, you need to use the -n parameter to specify For a moment.

%patch When patching, usually the patches will be included in the source code tar.gz package, or placed in the SOURCES directory. The general parameters are:

  • %patch -p1 Use the Patch defined previously, -p1 is the first layer item that ignores the patch

  • %Patch2 -p1 -b xxx.patch applies the specified patch, -b refers to generating a backup file

Supplement

  • %setup does not add Any option, only the package will be opened.

  • %setup -n newdir Unzip the software package in the newdir directory.

  • %setup -c generates the directory before decompression.

  • %setup -b num Decompress the numth source file.

  • %setup -T does not use the default decompression operation.

  • %setup -T -b 0 Decompress the 0th source code file.

  • %setup -c -n newdir Specifies the directory name newdir and generates the rpm package in this directory.

  • %patch is the simplest patching method, automatically specifying the patch level.

  • %patch 0 uses the 0th patch file, equivalent to %patch ?p 0.

  • %patch -s does not display patching information.

  • %patch -T deletes all output files generated during patching.

%configure This is not a keyword, but a standard macro command defined by rpm. It means to execute the configure configuration of the source code in the /usr/src/asianux/BUILD/%{name}-%{version} directory. Using standard writing, the parameters defined in /usr/lib/rpm/marcros will be referenced. . Another non-standard way of writing is to refer to the parameter customization in the source code, for example: 

引用CFLAGS="$RPM_OPT_FLAGS" CXXFLAGS="$RPM_OPT_FLAGS" ./configure --prefix=%{_prefix}

%build Start building the package in /usr/src/asianux/BUILD/%{name}-%{ version} directory to perform make work

%install 开始把软件安装到虚拟的根目录中.在/usr/src/asianux/BUILD/%{name}-%{version}目录中进行make install的操作。这个很重要，因为如果这里的路径不对的话，则下面%file中寻找文件的时候就会失败。 常见内容有：

  • %makeinstall 这不是关键字，而是rpm定义的标准宏命令。也可以使用非标准写法：make DESTDIR=$RPM_BUILD_ROOT install或引用make prefix=$RPM_BUILD_ROOT install

  • 需要说明的是，这里的%install主要就是为了后面的%file服务的。所以，还可以使用常规的系统命令：引用install -d $RPM_BUILD_ROOT/和cp -a * $RPM_BUILD_ROOT/

%clean        清理临时文件

%pre           rpm安装前执行的脚本

%post        rpm安装后执行的脚本

%preun         rpm卸载前执行的脚本

%postun    rpm卸载后执行的脚本

%files 定义那些文件或目录会放入rpm中

%defattr (-,root,root)** 指定包装文件的属性，分别是(mode,owner,group)，-表示默认值，对文本文件是0644，可执行文件是0755

%changelog     变更日志

RPM包制作拓展

如果想为zabbix增加启动控制脚本或一些其他的配置文件，可以将其放在SOURCE下，然后复制过去

  • 将启动脚本放在SOURCE目录
