System Manager GNU Shepherd 1.0.0 (formerly dmd) has been introduced, combining the capabilities of an init system and tools for managing system services. It is noted that assigning the number 1.0 after 21 years of development signifies the project's readiness and its compliance with the functionality requirements of modern init systems and service managers. <\/p>\n
The project is being developed by the GNU Guix System distribution team as an alternative to the SysV-init init system, which supports dependencies. The managing daemon and utilities of Shepherd are written in Guile (one of the implementations of the Scheme language), which is also used to define settings and parameters for launching services. Shepherd is already employed in the GNU Guix System distribution and is also aimed at use in GNU\/Hurd but can run on any POSIX-compliant OS for which Guile is available. <\/p>\n
Shepherd udf\u00f8rer opgaver relateret til opstart og stop af tjenester, idet den tager hensyn til sammenh\u00e6ngen mellem dem, og dynamisk bestemmer og starter de tjenester, som den valgte tjeneste er afh\u00e6ngig af. Shepherd underst\u00f8tter ogs\u00e5 identifikation af konflikter mellem tjenester og forhindrer deres samtidige udf\u00f8relse. Projektet kan bruges som det prim\u00e6re init-system (init med PID 1), eller i en isoleret form til at styre baggrundsprocesser for enkeltbrugere (f.eks. til at starte tor, privoxy, mcron osv.) med de p\u00e5g\u00e6ldende brugeres rettigheder. <\/p>\n
Key innovations in GNU Shepherd 1.0.0: <\/p>\n
\n
Support has been added for services that periodically execute commands or Scheme code according to a specified schedule.\n
I teamet «herd status SERVICE» er der implementeret visning af h\u00f8jniveau information om tjenester, s\u00e5som PID, kommando og adresser, hvor netv\u00e6rksforesp\u00f8rgsler modtages, samt resum\u00e9er af nyligt tilf\u00f8jede logbeskeder. Derudover viser denne kommando nu g\u00e6ldende brugerhandlinger for tjenesten og informerer om tilg\u00e6ngeligheden af en erstatningstjeneste, der vil blive anvendt efter genstart af den nuv\u00e6rende tjeneste.\n
Kommandoen «herd status root» er nu ikke l\u00e6ngere et synonym for «herd status» og viser oplysninger om rodsprocessen shepherd.\n
For Linux-platformen er der blevet tilf\u00f8jet muligheden for genstart ved hj\u00e6lp af kexec-mekanismen («reboot —kexec») for at udskifte Linux-kernen uden fysisk genstart.\n
A log-rotation service has been added, responsible for periodic rotation of logs and the removal of outdated logs.\n
A system-log service has been added, which can be used as a replacement for the traditional syslogd system.\n
Der er tilf\u00f8jet en timer-tjeneste til at k\u00f8re kommandoer p\u00e5 et angivet tidspunkt, i lighed med v\u00e6rkt\u00f8jet «at». For eksempel, «herd schedule timer at 07:00 — mpg123 alarm.mp3».\n
Der er tilf\u00f8jet en transient-tjeneste til at k\u00f8re kommandoer i baggrunden, i lighed med v\u00e6rkt\u00f8jet systemd-run. For eksempel, «herd spawn transient -d $PWD — make -j4». <\/ul>\n
