代码实战

1. 新建dotnet项目，添加引用Quartz.net包
   入口程序：

static void Main(string[] args)
        {
            IConfiguration configuration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .Build();

            //Serilog
            var logPath = configuration["Serilog:Path"]?.ToString();
            var logTemplate = configuration["Serilog:Template"]?.ToString();
            Log.Logger = new LoggerConfiguration()
                          .MinimumLevel.Information()
                          .WriteTo.Console()
                          .WriteTo.File(logPath,
                                        rollingInterval: RollingInterval.Day,
                                        outputTemplate: logTemplate,
                                        rollOnFileSizeLimit: true,
                                        fileSizeLimitBytes: 52428800 // 50MB
                                        )
                          .CreateLogger();

            CreateHostBuilder(args, configuration).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args, IConfiguration configuration)
        {
            IHostBuilder hostBuilder = Host.CreateDefaultBuilder(args).UseSerilog();
            hostBuilder.ConfigureServices((hostContext, services) =>
            {
                services.AddQuartz(q =>
                {
                    q.UseMicrosoftDependencyInjectionJobFactory();
                    q.AddJobAndTrigger<TestJob>(configuration);
                    q.AddJobAndTrigger<Test2Job>(configuration);
                });

                services.AddQuartzHostedService(q => q.WaitForJobsToComplete = true);
            });


            //Windows
            //if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
            //{ hostBuilder.UseWindowsService(); }

            //Linux
            if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
            { hostBuilder.UseSystemd(); }

            return hostBuilder;
        }

QuartzConfigurator：

    public static class QuartzConfigurator
    {
        public static void AddJobAndTrigger<T>(this IServiceCollectionQuartzConfigurator quartz, IConfiguration config) where T : IJob
        {
            // Use the name of the IJob as the appsettings.json key
            string jobName = typeof(T).Name;

            // Try and load the schedule from configuration
            var configKey = $"Quartz:{jobName}";
            var cronSchedule = config[configKey];

            // Some minor validation
            if (string.IsNullOrEmpty(cronSchedule))
            {
                throw new Exception($"No Quartz.NET Cron schedule found for job in configuration at {configKey}");
            }

            // register the job as before
            var jobKey = new JobKey(jobName);
            quartz.AddJob<T>(opts => opts.WithIdentity(jobKey));

            quartz.AddTrigger(opts => opts
                .ForJob(jobKey)
                .WithIdentity(jobName + "_trigger")
                .WithCronSchedule(cronSchedule)); // use the schedule from configuration
        }
    }

appsettings.json：

{
  "Serilog": {
    "Path": "Logs/job.log",
    "Template": "{NewLine}Date：{Timestamp:yyyy-MM-dd HH:mm:ss.fff} LogLevel：{Level} Message：{Message} {Exception}"
  },
  "Quartz": {
    "Test2Job": "0/8 * * * * ?",
    "TestJob": "0/5 * * * * ?"
  }
}

2. 新建.service文件，用作linux服务配置

[Unit]
Description=BPM.JobMgr service

[Service]
# The systemd service file must be configured with Type=notify to enable notifications.
Type=notify
# will set the Current Working Directory (CWD). Worker service will have issues without this setting
WorkingDirectory=/srv
# systemd will run this executable to start the service
ExecStart=/srv/bpmjobmgr/BPM.JobMgr.dll
# to query logs using journalctl, set a logical name here  
SyslogIdentifier=bpmjobmgr

# Use your username to keep things simple.
# If you pick a different user, make sure dotnet and all permissions are set correctly to run the app
# To update permissions, use 'chown yourusername -R /srv/Worker' to take ownership of the folder and files,
#       Use 'chmod +x /srv/Worker/MyService' to allow execution of the executable file
User=root

# This environment variable is necessary when dotnet isn't loaded for the specified user.
# To figure out this value, run 'env | grep DOTNET_ROOT' when dotnet has been loaded into your shell.
Environment=DOTNET_ROOT=/usr/share/dotnet/dotnet

# This gives time to MyService to shutdown gracefully.
TimeoutStopSec=300

[Install]
WantedBy=multi-user.target

3. windows10安装WSL2，建议选用Ubuntu 22.04版本方便启用systemd。WSL2安装dotnet6 runtime。
   https://learn.microsoft.com/zh-cn/windows/wsl/systemd

   https://learn.microsoft.com/zh-cn/dotnet/core/install/linux-ubuntu-install?tabs=dotnet8&pivots=os-linux-ubuntu-2204#ubuntu-2204

4. Linux Systemd配置

.service文件cp到Ubuntu的/etc/systemd/system/ 目录下

cp /mnt/c/benj/bpmjobmgr.service /etc/systemd/system/

reload配置文件

systemctl daemon-reload

检查配置文件

systemctl status bpmjobmgr

enable并启动服务

systemctl enable bpmjobmgr
systemctl start bpmjobmgr

6. 执行效果
