最近使用Melang语言写了一个supervisor相似服务Meproc来管理进程。 Meproc有如下特性： 使用HTTP API管理控制Meproc来管理进程跨平台，支持UNIX/Linux、Mac、Windows等平台支持cron类定时调度任务支持简单的任务间依赖关系无需安装，有Melang解释器即可，也有现成的docker image直接可用使用示范： 首先启动Meproc melang meproc.m默认监听127.0.0.1:8606。 启动后我们可以启动一个仅执行一次的任务，拉起一组进程去sleep 5秒： curl -XPUT http://127.1:8606/proc -d '{"name": "sleep1", "cmd": "sleep 5", "type": "once", "replica": 2}'然后再启动一个一次性任务sleep 5秒，但这个任务是依赖于上一个任务（sleep1）的。 curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep2", "cmd": "sleep 5", "type": "once", "replica": 2, "deps": ["sleep1"]}'我们也可以创建一个cron类型的定时任务，每分钟拉起一组进程，让他们sleep 5秒： curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep2", "cmd": "sleep 5", "type": "cron", "cron": "* * * * *", "replica": 2}'也可以查询当前运行中的进程有哪些，以及使用API下发的任务有哪些： curl -v -XGET http://127.1:8606/proc当然也支持停止任务： curl -v -XDELETE http://127.1:8606/proc?name=sleep1或者重启某个任务，例如： curl -v -XPOST http://127.1:8606/proc?name=sleep2一起看一个完整的示例，我们可以在启动Meproc后，执行如下命令： curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep1", "cmd": "sleep 5", "type": "once", "replica": 2}'curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep2", "cmd": "sleep 5", "type": "once", "replica": 2, "deps": ["sleep1"]}'curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep3", "cmd": "sleep 5", "type": "once", "replica": 2, "deps": ["sleep1", "sleep2"]}'curl -v -XDELETE http://127.1:8606/proc?name=sleep1curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep1", "cmd": "sleep 5", "type": "once", "replica": 2}'curl -v -XPOST http://127.1:8606/proc?name=sleep1curl -v -XPUT http://127.1:8606/proc -d '{"name": "sleep4", "cmd": "sleep 5", "type": "cron", "cron": "* * * * *", "replica": 2}'随后我们就可以在Meproc的终端上看到如下输出： 11/01/2023 10:28:28 UTC [INFO]: Listen: 127.0.0.1:860611/01/2023 10:28:31 UTC [INFO]: Task sleep1 started11/01/2023 10:28:31 UTC [INFO]: Task sleep1 stopped11/01/2023 10:28:31 UTC [INFO]: Task sleep2 started11/01/2023 10:28:32 UTC [INFO]: Task sleep1 started11/01/2023 10:28:32 UTC [INFO]: Task sleep1 stopped11/01/2023 10:28:32 UTC [INFO]: Task sleep1 started11/01/2023 10:28:37 UTC [INFO]: Process 1533616 (sleep2:1) exit11/01/2023 10:28:37 UTC [INFO]: Process 1533615 (sleep2:0) exit11/01/2023 10:28:37 UTC [INFO]: Process 1533626 (sleep1:1) exit11/01/2023 10:28:37 UTC [INFO]: Process 1533624 (sleep1:0) exit11/01/2023 10:28:37 UTC [INFO]: Task sleep3 started11/01/2023 10:28:42 UTC [INFO]: Process 1533685 (sleep3:0) exit11/01/2023 10:28:42 UTC [INFO]: Process 1533686 (sleep3:1) exit11/01/2023 10:28:45 UTC [INFO]: Task sleep4 started11/01/2023 10:28:50 UTC [INFO]: Process 1533747 (sleep4:0) exit11/01/2023 10:28:50 UTC [INFO]: Process 1533748 (sleep4:1) exit11/01/2023 10:30:00 UTC [INFO]: Task sleep4 started11/01/2023 10:30:05 UTC [INFO]: Process 1534633 (sleep4:0) exit11/01/2023 10:30:05 UTC [INFO]: Process 1534634 (sleep4:1) exit11/01/2023 10:30:20 UTC [INFO]: Task sleep4 stopped11/01/2023 10:30:20 UTC [INFO]: Task sleep4 started11/01/2023 10:30:25 UTC [INFO]: Process 1534878 (sleep4:0) exit11/01/2023 10:30:25 UTC [INFO]: Process 1534879 (sleep4:1) exit11/01/2023 10:30:32 UTC [INFO]: Task sleep4 stopped11/01/2023 10:30:32 UTC [INFO]: Task sleep4 started11/01/2023 10:30:37 UTC [INFO]: Process 1534999 (sleep4:0) exit11/01/2023 10:30:37 UTC [INFO]: Process 1535000 (sleep4:1) exit...欢迎感兴趣的小伙伴访问Meproc的Github仓库（https://github.com/MelonCTech/Meproc）了解更多内容。
