sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

0x01.修改源：

sudo vim /etc/apt/sources.list

输入密码
按i键，插入如下源地址：

Linux：彻底卸载nginx

1.先执行一下命令：

sudo apt-get --purge remove nginx
sudo apt-get autoremove
dpkg --get-selections|grep nginx

罗列出与nginx相关的软件， nginx-common deinstall 然后

sudo apt-get --purge remove nginx-common

这样就可以完全卸载掉nginx包括配置文件

2.ps -ef |grep nginx 看下nginx还有没有启动,一般执行完1后，nginx还是启动着的，如下：

yo@ubuntu:/$ ps -ef |grep nginx
root     4061  2418  0 Mar11 ?        00:00:00 nginx: master processsbin/nginx
nobody   4062  4061  0 Mar11 ?        00:00:00 nginx: worker process
yo  15487  4229  0 01:13 pts/0    00:00:00 grep --color=auto nginx

3.kill nginx进程

sudo kill -9  4061  4062

4.sudo find / -name nginx*

/usr/local/nginx
/usr/local/nginx/logs/nginx.pid
/usr/local/nginx/conf/nginx.conf.default
/usr/local/nginx/conf/nginx.conf
/usr/local/nginx/sbin/nginx

5.依依删除4列出的所有文件

sudo rm  -r  /usr/local/nginx
sudo rm  -r  /usr/local/nginx/logs/nginx.pid
sudo rm  -r  /usr/local/nginx/conf/nginx.conf.default
sudo rm  -r  /usr/local/nginx/conf/nginx.conf
sudo rm  -r  /usr/local/nginx/sbin/nginx

这样就彻底删除nginx了

中午吃完饭，迫不及待，上手ESP8266开发板，加上自己喜欢的python。于是，开始搞起。

0x00.Ready...

python2.7 on pc or mac.
usb线
ESP8266开发板

0x01.上MicroPython官网下载bin文件，地址：http://micropython.org/download/#esp8266

0x02.安装固件烧写工具：pip install esptool

0x03.USB连上开发板，上电

0x04.烧写固件：

擦除flash：
esptool.py --port {"serial port"} erase_flash

烧写固件：
esptool.py --port {"serial port"} --baud 460800 write_flash --flash_size=8m 0 {" firmware bin file..."}

0x05.Putty连接设备.enjoy!

0x00.这段时间做服务器接口测试，遇到一个需要动态获取校验码的，需要自己开发插件。

0x01.准备基本的开发环境eclipse，下载jmeter源码，导入工程。下载地址：http://jmeter.apache.org/download_jmeter.cgi，请选择你使用的jmeter对应版本的源码。
0x02.在src/functions下新建你自己的函数类
0x03.开始码代码：

package org.apache.jmeter.functions;

import java.util.Collection;
import java.util.LinkedList;
import java.util.List;
import org.apache.jmeter.engine.util.CompoundVariable;
import org.apache.jmeter.samplers.SampleResult;
import org.apache.jmeter.samplers.Sampler;

public class ｛"函数名称"｝extends AbstractFunction {
    
    //private static final Logger log = LoggingManager.getLoggerForClass();
    private static final List desc = new LinkedList();
    private static final String KEY = "__函数名称";
    private Object[] values = null;

    //Add arguments description
    static{
        desc.add("参数提示一");
        desc.add("参数提示二");
    }
    
    @Override
    public List getArgumentDesc() {
        // TODO Auto-generated method stub
        return desc;
    }

    @Override
    public String execute(SampleResult previousResult, Sampler currentSampler) throws InvalidVariableException {
        
        String numberString1 = ((CompoundVariable) values[0]).execute().trim();
        String numberString2 = ((CompoundVariable) values[1]).execute().trim();
        String 参数一;
        String 参数二;
        try{
            url = numberString1;
            isAuth = numberString2;
        } catch (Exception e){
            return null;
        }

        return String.valueOf(work(参数一,参数二));
    }
    
    public static void  print(String s){
        System.out.println(s);
    }

    private String work(String 参数一,String 参数二) {        
            
        String ret = null;
        //.....your code
        return ret;
    }

    @Override
    public void setParameters(Collection parameters) throws InvalidVariableException {
        //可以检查参数数量，主要包括以下两种方法
        checkMinParameterCount(parameters, 2);
        checkParameterCount(parameters, 2, 2);
        values = parameters.toArray();
        
    }

    @Override
    public String getReferenceKey() {
        //显示的函数名称
        return KEY;
    }
    
}
