## ECHECK可以做什么

* echeck是一个基于Python语言开发的脚本工具，主要包括eping、escan、ecurl、eshell四个核心指令
* [ecurl](#2)与curl指令相同，可以同时尝试访问多个地址，并输出结果
* [eping](#3)可以同时ping多个服务地址，并输出结果
* [escan](#4)为端口嗅探工具，最终返回端口嗅探结果
* [eshell](#5)可以远程执行指令

## ECHECK的使用

### 安装

> ECHECK基于Python3.7开发，安装工具前需要先安装python3

#### 1. 安装Python3

> 工具的开发基于Python3.7版本，未做过兼容性测试，使用时尽量安装3.7版本
* python3下载

> [Python下载地址](https://www.python.org)

* 选择对应版本进行安装即可

#### 2. 安装virtualenv

> 建议使用virtualenv，以简化外部环境对工具安装带来的影响,如果是linux或mac，可采用如下命令进行安装
```
$ pip install virtualenv
```
> 可执行help查看virtualenv使用指令
#### 3. 创建虚拟环境
```
$ virtualenv -p '指定python安装路径' venv
```
#### 4. 激活虚拟环境
```
$ source venv/bin/activate
```

#### 5. 安装ECHECK

> 在安装ECHECK前，需要先安装pycurl>=7.43.0.2

* 安装pycurl

__在安装pycurl前要确保已经安装了openssl，对于如何安装openssl，将在"常见问题"章节中进行详细说明__
```
$ export PYCURL_SSL_LIBRARY=openssl
$ pip install pycurl

```

* 源代码安装

> 下载源代码
```
$ git clone https://github.com/rockyCheung/easy_echeck.git
```
> 执行安装装指令
```
$ cd easy_echeck
$ python setup.py install

```
* 采用pip安装

```
$ pip install echeck
```

### 如何使用
#### 1. 配置文件conf.yml
> conf.yml是核心的配置文件，下边是一个简单的示例
```
#yaml config
#服务器的基础配置
server:
    log:
        log_file: echeck.log
        logger_name: main
        logger_level: DEBUG
#http协议检查
ecurl:
    url:
        - https://www.baidu.com
        - https://cn.bing.com
        - https://www.google.com
        - http://www.pathcurve.cn
        - http://www.easy.com

    index_file: echeck.htm
#网络联通性检查
eping:
    ip:
        - 127.0.0.1
        - 172.20.78.115
        - 172.20.79.255
        - google.cn
        - test.com
escan:
    - host:
        label: host_name1
        ip: 127.0.0.1
        port:
            - 80
            - 8080
    - host:
        label: host_name2
        ip: 172.20.78.115
        port:
            - 80
            - 8080

```
<h4 id="2">2. ecurl </h4>
* 配置

> ecurl适用于检查服务器http/https地址的联通性，若同时需要检查的地址有https://www.baidu.com、https://cn.bing.com、http://www.pathcurve.cn，在配置文件中需要做如下配置：

```
ecurl:
    url:
        - https://www.baidu.com
        - https://cn.bing.com
        - http://www.pathcurve.cn
```
> url可以配置多个地址，每个地址以"- "开头，标识为list结构

* 执行
```
$ ecurl [配置文件]
```
> 指令后的配置文件为可选参数，如果不带参数，则默认为当前路径下的conf.yml文件，其他指令与此同～

<h4 id="3"> 3. eping </h4>

* 配置

> eping适用于检查网络联通性，若同时需要检查的地址有127.0.0.1、172.20.78.115、172.20.79.255、google.cn、test.com，则在conf.yaml中需要增加如下配置：

```
eping:
    count: 4
    timeout: 5
    ip:
        - 127.0.0.1
        - 172.20.78.115
        - 172.20.79.255
        - google.cn
        - test.com
```
> count标识每个地址ping的次数，timeout是ping等待响应时长，以秒为单位

* 执行
```
$ eping  [配置文件]
```
<h4 id="4"> 4. escan </h4>

* 配置

> escan适用于扫描指定端口，端口可以是多个，具体配置示例如下：

```
escan:
    - host:
        label: host_name1
        ip: 127.0.0.1
        port:
            - 80
            - 8080
    - host:
        label: host_name2
        ip: 172.20.78.115
        port:
            - 80
            - 8080
```
* 执行
```
$ escan  [配置文件]
```

<h4 id="5"> 5. eshell </h4>

* 配置

> eshell适合于远程执行脚本，以远程执行删除镜像为例，具体配置示例如下：

```
eshell:
    - shell_cell:
        label: host_name1
        ip: 24.110.255.11
        port: 22
        user_name: root
        password: 123456
        exec_command:
             - docker rmi 9b0c10cae863
             - docker images
```

> __exec_command配置项包括两个指令:__

> docker rmi 9b0c10cae863 删除ID：9b0c10cae863的镜像

> docker images 查询本机所有镜像

> __eshell支持任何远程服务器指令，如果想查看服务器硬盘使用情况、系统资源限制，常规做法是先远程登陆服务器，然后，执行如下两个指令：__

> df -h

> ulimit -a

> __但如果需要同时查看10台服务器情况，那就会略显烦躁，如果是50台、100台呢？就这样被自己傻哭了，趴在电脑前认认真真敲三天指令，第四天发现前边90台的资源使用情况都忘记了～现在有了eshell，一切变简单了，下边以在多台服务器同时执行 df -h、ulimit -a、ls /opt指令为例：__


> df、ulimit、ls三个指令为例：
```
eshell:
    - shell_cell:
        label: host_name1
        ip: 24.110.255.11
        port: 22
        user_name: root
        password: 123456
        exec_command:
             - df -h
             - ulimit -a
             - ls /opt
    - shell_cell:
        label: host_name2
        ip: 24.110.255.12
        port: 22
        user_name: root
        password: 123456
        exec_command:
             - df -h
             - ulimit -a
             - ls /opt
```

* 执行
```
$ eshell  [配置文件]
```
> 执行过程中可能会有警告信息CryptographyDeprecationWarning，这是因为paramiko中引用的一些方法在cryptography>=2.6.1以上版本可能废弃，不影响使用，若觉得碍眼可以将cryptography版本调整为2.4.2。

> 执行完成后echeck.log打印日志如下：

## 常见问题

### 运行时警告

> __paramiko中引用的一些方法在cryptography>=2.6.1以上版本可能废弃，所以在运行过程中可能会有以下警告信息:__

> * CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a future version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
> * CryptographyDeprecationWarning: Support for unsafe construction of public numbers from encoded data will be removed in a future version. Please use EllipticCurvePublicKey.from_encoded_point
  self.curve, Q_S_bytes
> * CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a future version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
  hm.add_string(self.Q_C.public_numbers().encode_point())

> **建议将cryptography版本调整为2.4.2。**

### 安装过程报错

> * 安装echeck报错

```markdown
Failed building wheel for pycurl
```

> __解决方法安装前先执行:__
```
$ export PYCURL_SSL_LIBRARY=openssl
$ pip install pycurl
```
> * 安装pycurl时报找不到openssl/ssl.h的错误
```

src/pycurl.h:164:13: fatal error: 'openssl/ssl.h' file not found
    #   include <openssl/ssl.h>
                ^~~~~~~~~~~~~~~
    1 error generated.
    error: command 'gcc' failed with exit status 1

    ----------------------------------------

```
> 解决办法安装openssl

__在mac下执行如下指令__
```
$ brew install openssl
```
__因为考虑到用户可能会使用TLS，brew在安装openssl时不会设置为默认首选模块，所以为了在使用或编译时可以找到openssl，需要做如下设置__

```markdown
$ echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
$ source ~/.bash_profile
$ export LDFLAGS="-L/usr/local/opt/openssl/lib"
$ export CPPFLAGS="-I/usr/local/opt/openssl/include"
$ export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

```
__然后在执行pycurl的安装指令__
```markdown
$ export PYCURL_SSL_LIBRARY=openssl
$ pip install pycurl
```
## 版本说明

* 2.0.2版本
> 1. 为了方便标识设备，增强设备的辨识性，在eshell、escan指令中增加了label设置，用户可以根据实际需求用户个性化的标签标识设备
> 2. 在这个版本中同时补充了使用说明以及常见错误的处理方法
