大家好，今天小编为大家分享关于免root权限版gg修改器_免root修改器下载的内容，赶快来一起来看看吧。

一、Goreplay 介绍

• Goreplay 使用 Golang 写的一个 HTTP 实时流量复制工具。功能更强大，支持流量的放大、缩小，频率限制，还支持把请求记录到文件，方便回放和分析，也支持和 ElasticSearch 集成，将流量存入 ES 进行实时分析。
• GoReplay 不是代理，而是监听网络接口上的流量，不需要更改生产基础架构，而是在与服务相同的计算机上运行 GoReplay 守护程序。
• 特点：简单易用
• 地址：https:///buger/goreplay
• stars：14.1k

与 TCPCopy 相比它的架构更简单，只有一个 gor 组件，如下：

只需要在生产服务器上启动一个 gor 进程，它负责所有的工作包括监听、过滤和转发。 它的设计遵循 Unix 设计哲学：一切都是由管道组成的，各种输入将数据复用为输出。

二、Golang环境安装

一 、首先安装Golang及相关依赖环境 在官网上下载安装包或者go的一些中文网站上下载安装包

• https://golang.org/dl/
• https:///dl

我下载的是: go1.15.5.linux-amd64.tar.gz

二、解压到/usr/local目录下

tar -C /usr/local -zxvf go1.14.4.linux-amd64.tar.gz

三、配置环境变量

# 打开
vim /etc/profile

# 添加
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

# 编译生效
source /etc/profile

四、验证

go env

[root@vm ~]# go version
go version go1.15.5 linux/amd64

三、Goreplay 安装

从https:///buger/gor/releases 下载最新的 Gor 二进制文件（提供 Windows、Linux x64 和 Mac OS 的预编译二进制文件），也可以自己编译 。

下载二进制包：

[root@vm-1 ~]# curl -L -O https:///buger/goreplay/releases/download/v1.3.1/gor_1.3.1_x64.tar.gz
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 626 100 626 0 0 741 0 --:--:-- --:--:-- --:--:-- 741
100 10.5M 100 10.5M 0 0 3258k 0 0:00:03 0:00:03 --:--:-- 5951k

[root@vm-1 ~]# tar xvzf gor_1.3.1_x64.tar.gz
gor

解压缩包后，您可以从当前目录运行 Gor，或者您可能希望将二进制文件复制到您的 PATH（对于 Linux 和 Mac OS，它可以是 /usr/local/bin）。

四、Goreplay 使用示例

1、准备 RESTful API 环境

接口设计：

请求类型 请求路径 功能 Get /person 查询所有人 Post /person/two 事务测试

打包程序分别放到两台服务器 run 起来。 ​

服务器一：

[root@vm-1 ~]# java -jar spirng-boot-demo-0.0.1-SNAPSHOT.jar

2、捕获服务器一流量保存到本地文件

在终端运行这个命令： ​

#将端口 8082 流量保存到本地的文件
sudo ./gor --input-raw :8082 --output-file=requests.gor

[root@vm-1 ~]# sudo ./gor --input-raw :8082 --output-file=requests.gor
Interface: eth0 . BPF Filter: ((tcp dst port 8082) and (dst host 172.16.106.149 or dst host fe80::f599:6e65:3dc9:b84a))
Interface: lo . BPF Filter: ((tcp dst port 8082) and (dst host 127.0.0.1 or dst host ::1))
Interface: virbr0 . BPF Filter: ((tcp dst port 8082) and (dst host 192.168.124.1))
2021/08/17 14:26:41 [PPID 17654 and PID 17655] Version:1.3.0

注意：

使用–output-file-append 选项可以将捕获流量保存为一个单独的文件 使用sudo并要求输入密码：为了分析网络，Gor 需要只有超级用户才能使用的权限。但是，可以为非 root 用户配置运行Gor 。

在 Postman 上向服务器一发送请求：

我们查看服务一日志：

Hibernate: select person0_.id as id1_0_, person0_.age as age2_0_, person0_.name as name3_0_ from person person0_
Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?
Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?
Hibernate: insert into person (age, name, id) values (?, ?, ?)
Hibernate: insert into person (age, name, id) values (?, ?, ?)

可以看到服务已经正常处理了。 ​

我们停掉在服务器一上运行的 Gor，可以看到已经生成了录制的请求文件：

[root@vm-1 ~]# ls -l | grep "requests"
-rw-r----- 1 root root 300 8月 17 14:33 requests_0.gor

我们看下请求文件的内容：

[root@vm-1 ~]# cat requests_0.gor
1 04481f92ac106afb42ce55ca 1629182282437724065 0
GET /person HTTP/1.1
User-Agent: PostmanRuntime/7.28.2
Accept: */*
Cache-Control: no-cache
Postman-Token: ab405d20-ef93-4ffb-b2f6-a16cf1205e7c
Host: 172.16.106.149:8082
Accept-Encoding: gzip, deflate, br
Connection: keep-alive

​

3、将流量从文件回放到服务器二

​现在是时候将原始流量回放到服务二中了。如果是多个请求并且它们将按照与记录的顺序和时间完全相同的顺序重放。 ​

–output-http 提供第二个服务的 URL

sudo ./gor --input-file requests_0.gor --output-http="http://172.16.106.237:8082"

[root@vm-1 ~]sudo ./gor --input-file requests_0.gor --output-http="http://172.16.106.237:8082"
2021/08/17 14:42:55 [PPID 12356 and PID 17914] Version:1.3.0
[DEBUG][elapsed 985.792µs]: [INPUT-FILE] FileInput: end of file ’requests_0.gor’

我们看到服务二的日志：

[root@vm-2 ~]# java -jar spirng-boot-demo-0.0.1-SNAPSHOT.jar

. ____ _ __ _ _
/\ / ___’_ __ _ _(_)_ __ __ _
( ( )\___ | ’_ | ’_| | ’_ / _` |

’ |____| .__|_| |_|_| |_\__, | / / / /
=========|_|==============|___/=/_/_/_/
:: Spring Boot :: (v2.3.8.RELEASE)

2021-08-17 14:18:34.814 INFO 12775 --- [ main] com.zuozewei.SpirngbootdemoApplication : Starting SpirngbootdemoApplication v0.0.1-SNAPSHOT on vm-hsyjy-znkzb-vbi-1.novalocal with PID 12775 (/root/spirng-boot-demo-0.0.1-SNAPSHOT.jar started by root in /root)
......

Hibernate: select person0_.id as id1_0_, person0_.age as age2_0_, person0_.name as name3_0_ from person person0_

日志说明服务正常响应。 ​

​

4、实时将流量请求打印到终端

通过命令：

sudo ./gor --input-raw :8082 --output-stdout

此命令其记录到标准控制台输出，请注意，默认情况下 GoReplay 不跟踪响应，您可以使用 –output-http-track-response 选项启用它们。 ​

[root@vm-1 ~]sudo ./gor --input-raw :8082 --output-stdout
Interface: eth0 . BPF Filter: ((tcp dst port 8082) and (dst host 172.16.106.149 or dst host fe80::f599:6e65:3dc9:b84a))
Interface: lo . BPF Filter: ((tcp dst port 8082) and (dst host 127.0.0.1 or dst host ::1))
Interface: virbr0 . BPF Filter: ((tcp dst port 8082) and (dst host 192.168.124.1))
2021/08/17 14:55:45 [PPID 18060 and PID 18061] Version:1.3.0
1 22ee1f92ac106afb594d205a 1629183362175214036 0
POST /person/two HTTP/1.1
User-Agent: PostmanRuntime/7.28.2
Accept: */*
Cache-Control: no-cache
Postman-Token: 4922ce23-5706-42c5-8a54-ade5d5aee785
Host: 172.16.106.149:8082
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Content-Length: 0

5、复制流量实时转发到服务器二

运行命令： ​

sudo ./gor --input-raw :8082 --output-http="http://172.16.106.237:8082"

[root@vm-1 ~]# sudo ./gor --input-raw :8082 --output-http="http://172.16.106.237:8082"
Interface: eth0 . BPF Filter: ((tcp dst port 8082) and (dst host 172.16.106.149 or dst host fe80::f599:6e65:3dc9:b84a))
Interface: lo . BPF Filter: ((tcp dst port 8082) and (dst host 127.0.0.1 or dst host ::1))
Interface: virbr0 . BPF Filter: ((tcp dst port 8082) and (dst host 192.168.124.1))
2021/08/17 14:59:49 [PPID 18118 and PID 18119] Version:1.3.0

在服务器二查看日志,.发现流量已经进来了：

Hibernate: select person0_.id as id1_0_, person0_.age as age2_0_, person0_.name as name3_0_ from person person0_
Hibernate: select person0_.id as id1_0_, person0_.age as age2_0_, person0_.name as name3_0_ from person person0_
Hibernate: select person0_.id as id1_0_, person0_.age as age2_0_, person0_.name as name3_0_ from person person0_ where person0_.age=?

6、压力测试

goreplay支持将捕获到的生产实际请求流量减少或者放大重播以用于测试环境的压力测试.压力测试一般针对 Input 流量减少或者放大。 ​

录制的请求文件：

[root@vm-1 ~]# cat requests.gor
1 040f1f92ac106afb7e8d5679 1629183084044026882 0
POST /person/two HTTP/1.1
User-Agent: PostmanRuntime/7.28.2
Accept: */*
Cache-Control: no-cache
Postman-Token: a8600dd1-28c1-4825-b6a2-68c42659942f
Host: 172.16.106.149:8082
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Content-Length: 0


[root@vm-jmeter ~]# cat requests.gor
1 040f1f92ac106afb7e8d5679 1629183084044026882 0
POST /person/two HTTP/1.1
User-Agent: PostmanRuntime/7.28.2
Accept: */*
Cache-Control: no-cache
Postman-Token: a8600dd1-28c1-4825-b6a2-68c42659942f
Host: 172.16.106.149:8082
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Content-Length: 0

我们可以看到主要是两个请求。

运行以下命令，将流量从文件回放到服务器二，并放大两倍：

[root@vm-1 ~]sudo ./gor --input-file "requests.gor|200%" --output-http="http://172.16.106.237:8082"
2021/08/17 15:03:58 [PPID 12356 and PID 18187] Version:1.3.0
[DEBUG][elapsed 1.361742ms]: [INPUT-FILE] FileInput: end of file ’requests.gor’

我们查看下服务二日志的处理情况：

Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?
Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?
Hibernate: insert into person (age, name, id) values (?, ?, ?)
Hibernate: insert into person (age, name, id) values (?, ?, ?)

我们可以看到服务处理了四个请求。​

注意，当然也支持请求流量 10%,20% 等缩小。 ​

五、总结

今天简单介绍 Gor的常见玩法，事实上远不止上述提到的这些，更多的玩法有时间再写。 ​
