将java的jar包，打包为rpm 安装包

2022-02-18 02:15:43

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。

Complete!

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 Starter

License:        ASL 2.0

URL:            https://spring.io

Source0:        spring-starter-test-%{version}.jar

Source1:	%{name}.service

Requires:       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 #####

%install

app_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 #####

%post

# ensure Spring Starter service is enabled and running

%systemd_post %{name}.service

%{_bindir}/systemctl enable %{name}.service

%{_bindir}/systemctl start %{name}.service

##### UNINSTALL SECTION #####

%preun

# ensure Spring Starter service is disabled and stopped

%systemd_preun %{name}.service

%postun

case "$1" in

	0) # This is a package remove

		# remove app and data folders

		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
