一、rpm包 介绍

RPM Package Manager (RPM) 是一个强大的命令行驱动的软件包管理工具，用来安装、卸载、校验、查询和更新 Linux 系统上的软件包

二、环境安装

  • 一台centos7系统
  • 准备一个spring boot 项目jar 包 ，举个栗子：spring-starter-test-0.1.0.jar
  • 开始安装依赖工具包
  • 1、rpmbuild-用于生成rpm的实用程序
  • 2、rpmdev-开发实用程序以生成rpm。
  • 3、rpmlint-用于检查rpm包中常见错误的工具。

  • 安装完成！

三、项目设置

1、创建初始rpm文件夹结构。

[root@localhost ~]# cd ~; mkdir rpmbuild; cd ~/rpmbuild; rpmdev-setuptree
[root@localhost rpmbuild]# pwd
/root/rpmbuild
[root@localhost rpmbuild]#

2、将jar项目文件包文件复制到源文件夹中。

[root@localhost ~]# cp /root/package/spring-starter-test-0.1.0.jar SOURCES/

注意：示例服务将由systemd管理，因此我们还必须将服务文件打包到rpm中。

创建vim SOURCES/spring-starter-test.service具有以下内容的文件：

[root@localhost rpmbuild]# ll
total 0
drwxr-xr-x. 2 root root 6 Aug 6 03:35 BUILD
drwxr-xr-x. 2 root root 6 Aug 6 03:35 RPMS
drwxr-xr-x. 2 root root 6 Aug 6 03:35 SOURCES
drwxr-xr-x. 2 root root 6 Aug 6 03:35 SPECS
drwxr-xr-x. 2 root root 6 Aug 6 03:35 SRPMS
[root@localhost rpmbuild]# vim SOURCES/spring-starter-test.service

文件内容为：

[Unit]
Description=Spring Starter
After=network-online.target[Service]
Type=simple
WorkingDirectory=/var/opt/spring-starter-test
ExecStart=/usr/bin/java -jar /usr/local/spring-starter-test/spring-starter-test.jar
Restart=on-abort
User=spring-starter
Group=spring-starter[Install]
WantedBy=multi-user.targe

四、开始编写规范文件

规范文件定义了rpm构建过程和安装过程。

为我们的spring starter应用程序创建一个规范文件。

[root@localhost rpmbuild]# vim SPECS/spring-starter-test.spec

并设置以下内容：

##### HEADER SECTION #####Name: spring-starter-test
Version: 0.1.0
Release: 0
Summary: Rpm package for Spring StarterLicense: ASL 2.0
URL: https://spring.io
Source0: spring-starter-test-%{version}.jar
Source1:%{name}.serviceRequires: shadow-utils,bash
BuildRequires:systemd
%{?systemd_requires}BuildArch: noarch%description
%{summary}# disable debuginfo, which is useless on binary-only packages
%define debug_package %{nil}# do not repack jar files
%define __jar_repack %{nil}##### PREPARATION SECTION #####
%prep# empty section##### BUILD SECTION #####
%build# empty section##### PREINSTALL SECTION #####
%pre# create Spring Starter service group
getent group spring-starter >/dev/null || groupadd -f -g 30000 -r spring-starter# create Spring Starter service user
if ! getent passwd spring-starter >/dev/null ; then
if ! getent passwd 30000 >/dev/null ; then
useradd -r -u 30000 -g spring-starter -d /home/spring-starter -s /sbin/nologin -c "Spring Starter service account" spring-starter
else
useradd -r -g spring-starter -d /home/spring-starter -s /sbin/nologin -c "Spring Starter service account" spring-starter
fi
fi
exit 0##### INSTALL SECTION #####
%installapp_dir=%{buildroot}/usr/local/spring-starter-test
data_dir=%{buildroot}/var/opt/spring-starter-test
service_dir=%{buildroot}/%{_unitdir}# cleanup build root
rm -rf %{buildroot}
mkdir -p %{buildroot}# create app folder
mkdir -p $app_dir# create data folder
mkdir -p $data_dir# create service folder
mkdir -p $service_dir# copy all files
cp %{SOURCE0} $app_dir/spring-starter-test.jar
cp %{SOURCE1} $service_dir##### FILES SECTION #####
%files# define default file attributes
%defattr(-,spring-starter,spring-starter,-)# list of directories that are packaged
%dir /usr/local/spring-starter-test
%dir %attr(660, -, -) /var/opt/spring-starter-test# list of files that are packaged
/usr/local/spring-starter/spring-starter-test.jar
/usr/lib/systemd/system/%{name}.service##### POST INSTALL SECTION #####

%systemd_preun %{name}.service%postuncase "$1" in

rm -rf /usr/local/spring-starter-test
rm -rf /var/opt/spring-starter-test# remove Spring Starter service user and group
userdel spring-starter
;;
1) # This is a package upgrade
# do nothing
;;
esac# ensure Spring Starter service restartet if an upgrade is performed
%systemd_postun_with_restart %{name}.service##### CHANGELOG SECTION #####
%changelog* August 6, 2020 date liuxd <liuxd1314@sina.com> - 0.1.0-0
- First spring-starter-test package

  • 此处有一个注意点是：%define __jar_repack %{nil}定义。此选项禁用.jar文件压缩。如果jar文件被压缩，它将变得无法执行。

五、开始构建进行运行

  • 构建

    开始验证文件内容正确性

# Rpmlint之后会有很多错误及警告，大多数警告可以忽略。
[root@localhost rpmbuild]# rpmbuild -ba SPECS/spring-starter.spec

  • 正式开始构建

[root@localhost rpmbuild]# rpmbuild -ba SPECS/spring-starter-test.spec

  • 命令说明：

    1、 完全打包

    rpmbuild -ba xxx.spe

    2、只需要生成完整的源文件

    rpmbuild -bp xxx.spec
  • 已经完成打包，我们开始安装成果

#生成后的安装包是在： RPMS/noarch/spring-starter-test-0.1.0-0.noarch.rpm
[root@localhost noarch]# pwd
/root/rpmbuild/RPMS/noarch/spring-starter-test-0.1.0-0.noarch.rpm
[root@localhost rpmbuild]# rpm -ivh RPMS/noarch/spring-starter-test-0.1.0-0.noarch.rpm

六、安装完成，我们可以开始访问项目接口了

[root@localhost rpmbuild]# systemctl status spring-starter-test
[root@localhost rpmbuild]# curl http://127.0.0.1:8080/test/user/login?username=test001&password=123456
