debian下普通用户操做systemd服务

问题描述：
使用普通帐号test经过systemctl启动系统服务提示须要输入root密码：

解决方案：
根据上面提示得知权限由polkit进行管理，对应的是org.freedesktop.systemd1.policy这个配置文件下的manae-units动做

进入/usr/share/polkit-1/actions/org.freedesktop.systemd1.policy，

将对应manae-units的defaults中的受权所有改成yes，而后执行systemctl restart polkit重启polkit

<defaults>
        <allow_any>yes</allow_any>
        <allow_inactive>yes</allow_inactive>
        <allow_active>yes</allow_active>
</defaults>

下图为权限可选的配置参数 

defaults

This element is used to specify implicit authorizations for clients. Elements that can be used inside defaults include: allow_any Implicit authorizations that apply to any client. Optional. allow_inactive Implicit authorizations that apply to clients in inactive sessions on local consoles. Optional. allow_active Implicit authorizations that apply to clients in active sessions on local consoles. Optional. Each of the allow_any, allow_inactive and allow_active elements can contain the following values: no Not authorized. yes Authorized. auth_self Authentication by the owner of the session that the client originates from is required. Note that this is not restrictive enough for most uses on multi-user systems; auth_admin* is generally recommended. auth_admin Authentication by an administrative user is required. auth_self_keep Like auth_self but the authorization is kept for a brief period (e.g. five minutes). The warning about auth_self above applies likewise. auth_admin_keep Like auth_admin but the authorization is kept for a brief period (e.g. five minutes).
