条件说明 自己用的mac开发电脑，电脑还装了很多软件并在运行，但是swoole和php-fpm都在这运行，所以是公平的

swoole使用easyswoole框架

php-fpm 使用laravel框架

php-fpm配置: max_requests=204800 max_children=100000 start_servers=100 max_spare_servers=1000 min_spare_servers100

nginx配置： worker_processes =4 worker_connections=100000

使用Mac自带的ab工工具，请求数10000，并发100

cpu情况

swoole100%都是11毫秒内完成，每秒可服务14571个请求，cpu使用接近100%

php-fpm 都是在1秒以上完成的，每秒可服务75个请求，cpu使用平时是10%左右，压测的时候%17左右

因为系统的二进制在存储某些数据的时候，二进制可能是无限的，所以就导致加减法和乘法会变无限循环小数的问题

//实验在php 7.2下进行
var_dump(0.58 * 100);//这种情况不会有问题
var_dump(json_encode(['a' => 0.58 * 100]));

float(58)
string(23) "{"a":57.99999999999999}"

解决办法是使用更高精度的函数

var_dump(json_encode(['a' => bcmul(0.58, 100)]));
string(10) "{"a":"58"}"

bcadd — 将两个高精度数字相加

bccomp — 比较两个高精度数字，返回-1, 0, 1

bcdiv — 将两个高精度数字相除

bcmod — 求高精度数字余数

bcmul — 将两个高精度数字相乘

bcpow — 求高精度数字乘方

bcpowmod — 求高精度数字乘方求模，数论里非常常用

bcscale — 配置默认小数点位数，相当于就是Linux bc中的”scale=”

bcsqrt — 求高精度数字平方根

bcsub — 将两个高精度数字相减

strtotime('-1 month',strtotime('2011-3-31')); 当31好的时候减一个月的时候，就是前一个月的31号，但是有些月份没有31号，就会往后下一个月移，就乱了

old日期可以减一个月或者加一个月的第一天，然后再把old的日期的天拼到新日期，在和新日期的最后一天比较，如果小于拼接的，就取最后一天，否则就取拼接的

if (!function_exists('calculate_month')) {
   /**
    * 对月进行加减
    * @param int $date 时间戳
    * @param string $algorithm 比如 +1 month 或者-1 month
    * @return string
    */
   function calculate_month(int $date, string $algorithm): string
   {
       $day = date('d', $date);
       $newDateFirst = date('Y-m', strtotime('first day of ' . $algorithm, $date));
       $newDate = $newDateFirst . '-' . $day;
       $newDateLast = date('Y-m-d', strtotime('last day of ' . $algorithm, $date));
       return $newDateLast < $newDate ? $newDateLast : $newDate;

   }
}

var_dump(calculate_month(strtotime('2020-05-31'),'-3 month'));
var_dump(calculate_month(strtotime('2020-08-31'),'+1 month'));
var_dump(calculate_month(strtotime('2020-08-15'),'+1 month'));

string(10) "2017-02-28"
string(10) "2017-09-30"
string(10) "2017-09-15"

由于mac会有python版本乱套问题，所以直接在python3 docker里安装部署

安装nikola

pip install "git+https://github.com/getnikola/nikola#egg=Nikola[extras]"

包

git clone https://github.com/getnikola/nikola

cd nikola

pip install -e ".[extras]"

初始化项目

nikola init --demo <directory_name>.

生成文章

nikola new_post -e.

然后编辑文章

构建

nikola build

启动服务浏览器访问

nikola serve --browser

可以根据喜好编辑conf.py

然后在github建个项目 git名称.github.io

clone到本地把Nikola项目拷在这 执行nikola build的目录的父目录，再把output里的全部目录拷到git项目的根目录

mac python Failed building wheel for thriftpy

解决办法：pip3 install cython thriftpy

docker run -v $PWD/myapp:/usr/src/myapp -it --rm -p 8000:8000 -w /usr/src/myapp python:3.5 bash 安装python和pip

$ pip install falcon

$ mkdir look $ cd look

$touch app.py import falcon api = application = falcon.API()

$ pip install gunicorn

$ gunicorn -b 0.0.0.0:8000 app（默认是127.0.0.1:8000，这样的话只有主机可以访问）

$ curl localhost:8000 -v

$ pip install --upgrade httpie

$ http localhoost:8000

pip install msgpack-python

$ http GET localhost:8000/images

方法一 在solr页面选择对应的core，然后点击Document然后Document Type选择XML,然后在Document(s)框内填)

<delete><query>*:*</query></delete> #*:*可以改成其他条件
<commit/>

方法二 post 请求http://ip:端口/solr/core/update?wt=json，<query>id:1</query>里的条件可以修改，post参数

<add commitWithin="1000" overwrite="true">
  <delete>
      <query>id:1</query>
  </delete>
  <commit></commit>
</add>

1.进入/home/solr/solr-6.6.2（solr安装路径）创建core，比如创建lab_cloud_periodical bin/solr create -c core名 -p 端口号 -force（root用户需要加）

2.导出mongodb csv 比如导出lab，-f是需要放在solr的且此集合有的字段 mongoexport --username 用户名 --password 密码 --type=csv -f _id,title -d 数据库 -c 集合 -o /home/文件名.csv

3.把数据传到solrcurl http://ip:端口号/solr/core/update?commit=true --data-binary @/home/文件名.csv -H 'Content-type:text/csv; charset=utf-8'

问题： 可能执行着会报错，那是solr会给字段定义类型，但你的某些值有不是那个类型，比如给你定义了int,然后你传的值是字符串。解决办法就是去把int改成string，位置在vim /home/solr/solr-6.6.2/server/solr/lab（写core名）/conf/managed-schema,比如这的tid(有些是默认给你设置了时间，但你传入的不是时间格式)，这是我遇到的问题，有些配置想改都可以改的。然后重新导入数据，还有就是主键可以重新设置，修改<uniqueKey>id</uniqueKey>

4.如果需要删除数据参考：http://blog.csdn.net/lbf5210/article/details/51207043

5.查询，页面参数解释：http://blog.csdn.net/zhufenglonglove/article/details/51518846 浏览器进入http://ip:端口号/solr

6.目前能弄的mongo实时更新是一个core记录整个库，一个集合一个core不知道咋弄。
