公司的系统都是内网，无法连接互联网，所以没办法只有源码安装了。

看了下 saltstack 的官网，需要安装的包有

https://docs.saltstack.com/en/latest/topics/installation/index.html

Salt should run on any Unix-like platform so long as the dependencies are met.

Python 2.6 >= 2.6 <3.0
msgpack-python – High-performance message interchange format
YAML – Python YAML bindings
Jinja2 – parsing Salt States (configurable in the master settings)
MarkupSafe – Implements a XML/HTML/XHTML Markup safe string for Python
apache-libcloud – Python lib for interacting with many of the popular cloud service providers using a unified API
Requests – HTTP library

Depending on the chosen Salt transport, ZeroMQ or RAET, dependencies vary:

ZeroMQ:
- ZeroMQ >= 3.2.0
- pyzmq >= 2.2.0 – ZeroMQ Python bindings
- PyCrypto – The Python cryptography toolkit
- M2Crypto – “Me Too Crypto” – Python OpenSSL wrapper
RAET:
- libnacl – Python bindings to libsodium
- ioflo – The flo programming interface raet and salt-raet is built on
- RAET – The worlds most awesome UDP protocol

Salt defaults to the ZeroMQ transport, and the choice can be made at install time, for example:

python setup.py --salt-transport=raet install


一般都使用 zeromq, 其余的包安装都很顺利，没遇到什么问题，安装 zeroMQ 的时候遇到不少问题，查了好多资料，这里记录下，免得以后又忘记了 
1. 安装 pyzmq 的时候报错
python setup.py install
 最后报错

gcc: error trying to exec ‘cc1plus’: execvp: 没有那个文件或目录

error: command ‘gcc’ failed with exit status 1

查询很多网址后发现说明是 gcc 和 g ++ 版本不一致导致的问题，一查，发现操作系统根本就没安装 g ++，安装个 g ++ 后重新安装正常

2. 安装 M2Crypto 时报错

building ‘M2Crypto.__m2crypto’ extension

swigging SWIG/_m2crypto.i to SWIG/_m2crypto_wrap.c

swig -python -I/usr/include/python2.7 -I/usr/include -I/usr/include/openssl -includeall -modern -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i

unable to execute swig: No such file or directory

error: command ‘swig’ failed with exit status 1

发现安装 m2crypto 需要用到 swig，而本机上没有安装 swig，所以报错，就需要安装 swig，此处又给后面挖了一个坑

在 swig 的主页上下载了最新版的 swig 3.0.7

安装完 swig 后继续安装 M2Crypto，继续报错

Running setup.py install for M2Crypto building 'M2Crypto.__m2crypto' extension swigging SWIG/_m2crypto.i to SWIG/_m2crypto_wrap.c swig -python -I/usr/include/python2.6 -I/usr/include -includeall -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i /usr/include/openssl/opensslconf.h:31: Error: CPP #error ""This openssl-devel package does not work your architecture?"". Use the -cpperraswarn option to continue swig processing. error: command 'swig' failed with exit status 1

根据这个报错提示结合搜索到的结果，在 M2Crypto 目录的 setup.py 中加上一句

self.swig_opts.append(‘-cpperraswarn’)

重新安装没有报错

其余的包安装都很顺利，没有报错

本以为安装好了，执行 salt-master，这次没有报什么什么库找不到了，又报了一个新的错误

[ERROR] ‘module’ object has no attribute ‘PKCS5_SALT_LEN’
