任务调度 RuQi(如期)

要相信，一切所期盼的，都会如期而至

1 架构

高可用部署如期，ruqi1 和 ruqi2 均为 butterfly 应用，ruqi1 和 ruqi2 分别部署在两台不同的机器上

+---------------+        +---------------+

如期可提供定时、周期性执行 python/shell 脚本、发送 HTTP POST 请求、发布百川任务的功能

2.1 建表

use {database};

2.2 配置

<butterfly_project>/conf/config.py

...
DATABASES = {
    "default": "mysql+retrypool://<user>:<password>@<ip>:<port>/<database>?max_connections=300&stale_timeout=300"
}
...
# Scheduler
scheduler_store = "mysql"      # ("mysql"/"memory")

2.3 应用

将 examples/ruqi/handlers/ruqi 目录移动到 <butterfly_project>/handlers/ 下

3.1 添加任务

3.1.1 参数

job_trigger: 触发方式 (cron/interval/date)
           ：cron：crontab 规则触发
           : interval: 固定周期触发
           : date: 指定时间触发，仅会执行一次
job_id     : job id(唯一索引)
job_name   : 用作分类
cmd        : job cmd
           :【脚本 1          】bash scripts/xx/xx.sh
           :【脚本 2          】python scripts/xx/xx.py arg1 arg2
           :【URL POST 请求 1 】http://127.0.0.1:8585/demo_api/hello#{"str_info":"hello"}
           :【URL POST 请求 2 】http://127.0.0.1:8585/demo_api/ping
           :【百川请求 1      】/demo_api/hello#{"str_info":"hello"}
           :【百川请求 2      】/demo_api/ping
rule       :
           ：cron     规则: "*(秒) *(分) *(时) *(日) *(月) *(周)"，如："0 20 2 * * *"(每天凌晨 2:20 进行操作)
           : interval 规则: 固定周期触发: Xs/Xm/Xh/Xd, 如: 10s(每 10s 进行一次操作)
           : date     规则: 2020-12-16 18:03:17/2020-12-16 18:05:17.682862/now (now 为立即触发一次)

3.1.2 例子

周期任务

eg: 每 10s 向百川中添加一次 /demo_api/hello 的请求

from  xlib.util import http_util
data = {
        "job_trigger": "interval",
        "job_id": "helloworld",
        "job_name": "ceshi",
        "cmd": '/demo_api/hello#{"str_info": "%s"}' % "helloworld",
        "rule": "10s"
        }
res = http_util.post_json("http://127.0.0.1:8200/ruqi/job_add", data=data)
print res.output()

延迟任务

eg: 任务 1 小时后再发起执行

from xlib.util import http_util
from xlib.util import time_util

cur_time = time_util.get_current_time()

# 1 hour later
exe_time = cur_time + 3600
exe_time_str = time_util.timestamp2time_str(exe_time)

data = {
        "job_trigger": "date",
        "job_id": "helloworld",
        "job_name": "ceshi",
        "cmd": '/demo_api/hello#{"str_info": "%s"}' % "helloworld",
        "rule": exe_time_str
        }

res = http_util.post_json("http://127.0.0.1:4100/ruqi/job_add", data=data)
print res.output()

例子，延时发起星桥任务

import json
from xlib.util import http_util
from xlib.util import time_util

cur_time = time_util.get_current_time()

# 1 hour later
exe_time = cur_time + 3600
exe_time_str = time_util.timestamp2time_str(exe_time)

instance_name = "proxy_396399"
params_dict = {
        "job_namespace": "except_unit",
        "job_type": "unit_delete",
        "job_name": instance_name,
        "job_extra": {
            "unit_id": instance_name
    }
}

data = {
        "job_trigger": "date",
        "job_id": instance_name,
        "job_name": "unit_delete",
        "cmd": "/xingqiao/create_job#{params_str}".format(params_str=json.dumps(params_dict)),
        "rule": exe_time_str
        }

res = http_util.post_json("http://127.0.0.1:4100/ruqi/job_add", data=data)
print res.output()
