将 rpm-package 安装到 systemd？

Question

我是 systemd 的新手，并试图将内部应用程序打包为 rpm，以安装在 systemd 主机（RHEL7）上。

rpm 尝试将 systemd .service-file: myapp.service 放入：/etc/systemd/system

但这会产生错误，我不明白：

file /etc/systemd from install of myapp-0:1-.i386 conflicts with file from package systemd-219-19.el7.x86_64
file /etc/systemd/system from install of myapp-0:1-.i386 conflicts with file from package systemd-219-19.el7.x86_64  

并且安装中止。

.service-file 中与安装相关的内容是：

[Unit]
Description=MyApp
After=syslog.target network.target activemq.service
Requires=activemq.service

[Install]
WantedBy=multi-user.target

[Service]
Type=simple
...

知道冲突可能是什么吗？

或者如何解决？

编辑：从 gradle 构建文件添加 rpm-stuff：

myappRpm {
    dependsOn build
    packageName 'myapp'
    arch I386
    os LINUX
    version buildVersion

    preInstall file('./deploy/rpm/preinstall')
    postInstall file('./deploy/rpm/postinstall')
    preUninstall file('./deploy/rpm/preuninstall')

    directory('/var/log/myapp', 755)
    directory('/opt/myapp/app', 755)
    directory('/opt/myapp/bin', 755)
    directory('/opt/myapp/config', 755)

    into '/opt/myapp'

    from('MyApp/build/libs/MyApp.war') {
        into '/opt/myapp/app/'
        fileMode 0755
    }

    from('deploy/systemd/myapp.sh') {
        into '/opt/myapp/bin/'
        fileMode 0755
    }

    from('deploy/systemd/myapp.env') {
        into '/opt/myapp/systemd/'
        fileMode 0755
    }

    from('deploy/systemd/myapp.service') {
        into '/etc/systemd/system/'
        fileMode 0755
    }

    doLast {
        file("$buildDir/distributions/myapp-${buildVersion}.i386.rpm").renameTo("$buildDir/distributions/myapp.rpm")
    }
}

每个 rpm 指定它安装的文件和目录的列表。两个 rpm 不能安装相同的文件或目录。在你的spec文件（或任何文件，你用来描述你创建RPM），你应该不安装/etc/systemd/和/etc/systemd/system/目录。在规范文件中；你不应该使用：

%files
/etc/systemd/

但

%files
/etc/systemd/system/*

（或分别指定每个文件）

四处寻找您的 gradle 插件；您应该使用以下addParentDirs选项：

from('deploy/systemd/myapp.service') {
    // Will tell redline-rpm not to auto create directories, which
    // is sometimes necessary to avoid rpm directory conflicts
    addParentDirs = false
    into '/etc/systemd/system/'
    fileMode 0755
}
