NixOS 和 NixOps 声明式组管理和服务

Question

是否可以在 NixOS 和 NixOps 中以声明式方式管理组？

\n\n

我希望能够在以下位置创建一个新组configuration.nix，并向其中添加用户。我无法找到任何可用的选项来执行此操作，并且遇到手动添加的组被新的 nixops 部署删除的问题。

我尝试过的

\n\n

我尝试修改文件中的服务创建的用户组configuration.nix：

\n\n

system.activationScripts = {\n  mediaGroup = \'\'\n    echo "Adding `media` group"\n    getent group media || groupadd media\n  \'\';\n};\n\nusers.users.plex.extraGroups = [ "media" ];\nusers.users.radarr.extraGroups = [ "media" ];\nusers.users.sonarr.extraGroups = [ "media" ];\nusers.users.deluge.extraGroups = [ "media" ];\n

\n\n

还可以通过修改 services、plex、radar、sonarr 和 deluge 来获取额外的组选项：

\n\n

{ config, pkgs, lib, ... }:\n\nwith lib;\n\nlet\n  cfg = config.services.sonarr;\nin\n{\n  options = {\n    services.sonarr = {\n      openFirewall = mkOption {\n        type = types.bool;\n        default = false;\n        description = \'\'\n          Open ports in the firewall for the media server\n        \'\';\n      };\n\n      user = mkOption {\n        type = types.str;\n        default = "sonarr";\n        description = "User account under which sonarr runs.";\n      };\n\n      group = mkOption {\n        type = types.str;\n        default = "sonarr";\n        description = "Group under which sonarr runs.";\n      };\n\n    };\n  };\n\n  config = mkIf cfg.enable {\n    systemd.services.sonarr = pkgs.lib.mkForce {\n      description = "Sonarr";\n      after = [ "network.target" ];\n      wantedBy = [ "multi-user.target" ];\n      preStart = \'\'\n        test -d /var/lib/sonarr/ || {\n          echo "Creating sonarr data directory in /var/lib/sonarr/"\n          mkdir -p /var/lib/sonarr/\n        }\n        chown -R ${cfg.user}:${cfg.group} /var/lib/sonarr/\n        chmod 0700 /var/lib/sonarr/\n      \'\';\n\n      serviceConfig = {\n        Type = "simple";\n        User = cfg.user;\n        Group = cfg.group;\n        PermissionsStartOnly = "true";\n        ExecStart = "${pkgs.sonarr}/bin/NzbDrone --no-browser";\n        Restart = "on-failure";\n      };\n    };\n\n     networking.firewall = mkIf cfg.openFirewall {\n      allowedTCPPorts = [ 8989 ];\n    };\n\n    users.users = mkIf (cfg.user == "sonarr") {\n      sonarr = pkgs.lib.mkForce {\n        uid = config.ids.uids.sonarr;\n        home = "/var/lib/sonarr";\n        group = cfg.group;\n        extraGroups = [ "media" ];\n      };\n    };\n\n    users.groups = mkIf (cfg.group == "sonarr") {\n      sonarr = pkgs.lib.mkForce {\n        gid = config.ids.gids.sonarr;\n      };\n    };\n\n  };\n}\n

我得到的每一个nixops deploy：

如果我检查每个用户组，即使我手动将用户添加到组中，我也会得到以下信息usermod：

\n\n

[root@my_server:/var/lib]# groups sonarr\nsonarr : nogroup\n

\n\n

语境

\n\n

这些服务之间缺乏共享组导致权限问题，阻止声纳和雷达自动将大量文件复制到复合媒体位置。我认为这是它工作的唯一问题，我还配置了 deluge 服务以使用 a umask，002并且权限似乎是正确的。

\n\n

[root@my_server:/var/lib/deluge/Downloads]# ls -l && cd MovieFolder && ls -l\ndrwxrwxr-- 2 deluge media 4096 Aug 26 11:39  MovieFolder\n-rw-rw-r-- 1 deluge media 2420763104 Aug 26 11:08  TheMovie.mkv\n

\n\n

还有来自声纳和雷达的消息：

\n\n

No files found are eligible for import in /var/lib/deluge/Downloads/MovieFolder\n

\n\n

以及一个示例日志消息：

\n\n

18-8-26 12:47:51.3|Error|DownloadedEpisodesImportService|Import failed, path does not exist or is not accessible by Sonarr: /var/lib/deluge/Downloads/MovieFolder\n

Answer 1

media您还需要定义组。

要么先明确定义它：

users.groups.media = {};
users.users.plex.extraGroups = [ "media" ];

或立即将成员添加到组中：

users.groups.media.members = [ ... ];
