Mac中的定时任务利器-launchctl

launchctl是一个统一的服务管理框架，可以启动、停止和管理守护进程、应用程序、进程和脚本等。
launchctl是通过配置文件来指定执行周期和任务的。

当然mac也可以像linux系统一样，使用crontab命令来添加定时任务，这里就不赘述，具体可参见：OS X 添加定时任务
下面将手把手教你在mac上创建定时任务。（任务目标：每天晚上十点定时执行/Users/demo/helloworld.py的python程序）

1. 创建run.sh脚本

进入 helloworld.py 程序所在目录
cd /User/demo
创建run.sh脚本
vi run.sh
添加执行helloworld.py的命令

#!/bin/sh

# 记录一下开始时间
echo `date` >> /Users/demo/log &&
# 进入helloworld.py程序所在目录
cd /Users/demo &&
# 执行python脚本（注意前面要指定python运行环境/usr/bin/python，根据自己的情况改变）
/usr/bin/python helloworld.py
# 运行完成
echo 'finish' >> /Users/demo/log

:x保存退出
注意，脚本要改成可执行的权限
chmod 777 run.sh

2. 编写plist文件

launchctl 将根据plist文件的信息来启动任务。
plist脚本一般存放在以下目录：

  • /Library/LaunchDaemons –>只要系统启动了，哪怕用户不登陆系统也会被执行
  • /Library/LaunchAgents –>当用户登陆系统后才会被执行

更多的plist存放目录：

~/Library/LaunchAgents 由用户自己定义的任务项
/Library/LaunchAgents 由管理员为用户定义的任务项
/Library/LaunchDaemons 由管理员定义的守护进程任务项
/System/Library/LaunchAgents 由Mac OS X为用户定义的任务项
/System/Library/LaunchDaemons 由Mac OS X定义的守护进程任务项

进入 ~/Library/LaunchAgents，创建一个plist文件com.demo.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <!-- Label唯一的标识 -->
  <key>Label</key>
  <string>com.demo.plist</string>
  <!-- 指定要运行的脚本 -->
  <key>ProgramArguments</key>
  <array>
    <string>/Users/demo/run.sh</string>
  </array>
  <!-- 指定要运行的时间 -->
  <key>StartCalendarInterval</key>
  <dict>
        <key>Minute</key>
        <integer>00</integer>
        <key>Hour</key>
        <integer>22</integer>
  </dict>

<string>/Users/demo/run.log</string>
<!-- 标准错误输出文件，错误日志 -->
<key>StandardErrorPath</key>
<string>/Users/demo/run.err</string>
</dict>
</plist>

3. 加载命令

launchctl load -w com.demo.plist
这样任务就加载成功了。

# 加载任务, -w选项会将plist文件中无效的key覆盖掉，建议加上
$ launchctl load -w com.demo.plist

# 删除任务
$ launchctl unload -w com.demo.plist

# 查看任务列表, 使用 grep '任务部分名字' 过滤
$ launchctl list | grep 'com.demo'

# 开始任务
$ launchctl start  com.demo.plist

# 结束任务
$ launchctl stop   com.demo.plist

如果任务呗修改了，那么必须先unload，然后重新load
start可以测试任务，这个是立即执行，不管时间到了没有
执行start和unload前，任务必须先load过，否则报错
stop可以停止任务

番外篇

plist支持两种方式配置执行时间：

  • StartInterval: 指定脚本每间隔多长时间（单位：秒）执行一次；
  • StartCalendarInterval: 可以指定脚本在多少分钟、小时、天、星期几、月时间上执行，类似如crontab的中的设置，包含下面的 key:
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    Minute <integer>
    The minute on which this job will be run.
    Hour <integer>
    The hour on which this job will be run.
    Day <integer>
    The day on which this job will be run.
    Weekday <integer>
    The weekday on which this job will be run (0 and 7 are Sunday).
    Month <integer>
    The month on which this job will be run.

plist部分参数说明：

1

Label：对应的需要保证全局唯一性；
Program：要运行的程序；
ProgramArguments：命令语句
StartCalendarInterval：运行的时间，单个时间点使用dict，多个时间点使用 array <dict>
StartInterval：时间间隔，与StartCalendarInterval使用其一，单位为秒
StandardInPath、StandardOutPath、StandardErrorPath：标准的输入输出错误文件，这里建议不要使用 .log 作为后缀，会打不开里面的信息。
定时启动任务时，如果涉及到网络，但是电脑处于睡眠状态，是执行不了的，这个时候，可以定时的启动屏幕就好了。

laravel + dingo/api + jwt 最佳实践

tymon/jwt-auth

安装

1
composer require tymon/jwt-auth:1.0.0-rc.5

需要注意的是jwt在laravel 5.7以上需要著名安装的版本

生成配置文件

1
php artisan jwt:secret

发布资源

3
php artisan vendor:publish --provider="Dingo\Api\Provider\LaravelServiceProvider"
# 或者不注明提供者，然后自己输入
php artisan vendor:publish

dingo/api

安装

1
composer requre dingo/api

发布资源

1
php artisan vendor:publish --provider="Dingo\Api\Provider\LaravelServiceProvider"

修改配置 config\api.php

  --prefix=PREFIX         install architecture-independent files in PREFIX                 
                          [/usr/local]

`/usr/local/bin', `/usr/local/lib' etc.  You can specify                                   
an installation prefix other than `/usr/local' using `--prefix',                           
for instance `--prefix=$HOME'.    
默认情况下， `make install'将安装`/usr/local/bin'、`/usr/local/lib'等。
您可以使用`--prefix`的去指定安装路径，                                                 
例如 `--prefix=$HOME`

Linux常用库介绍

GCC

GNU编译器套件，全名GNU Compiler Collection。是由 GNU 开发的编程语言编译器。现已被大多数类Unix操作系统（如Linux、BSD、Mac OS X等）采纳为标准的编译器。

1
yum install -y gcc

GCC-C++

GNU的C++编译器

1
yum install -y gcc-c++

PCRE

PCRE（Perl Compatible Regular Expressions，Perl兼容正则表达式）是由Philip Hazel开发的函数库，目前为很多软件所使用，该库支持正则表达式。它由RegEx演化而来，实际上，Perl正则表达式也是源自于Henry Spencer写的RegEx。

1
yum install -y pcre

pcre-devel

pcre-devel是使用PCRE做二次开发时所需要的开发库，包括头文件等，这也是编译Nginx所必须使用的。

1
yum install -y pcre-devel

zlib

zlib库用于对HTTP包的内容做gzip格式的压缩，如果我们在nginx.conf里配置了gzip on，并指定对于某些类型（content-type）的HTTP响应使用gzip来进行压缩以减少网络传输量，那么，在编译时就必须把zlib编译进Nginx。
同理，zlib是直接使用的库，zlib-devel是二次开发所需要的库。

1
yum install -y zlib zlib-devel

openssl

如果我们服务器不只是要支持HTTP,还要在更安全的ssl协议上传输HTTP,那么就需要拥有openssl了。另外，如果需要使用MD5,SHA1等散列函数，也会用到openssl。

yum install -y openssl
