源码安装saltstack的时候遇到的问题

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

DEPENDENCIES

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'

AttributeError: 'module' object has no attribute 'PKCS5_SALT_LEN'

又只有继续搜索，找了很长时间才发现说是swig新版本的一个bug，回退到3.0.4即可解决该问题，又重新下载swig 3.0.4安装，再重新安装M2Crypto，saltstack终于安装完成，源码安装真是痛苦，好在现在都是虚拟机，安装好一个制作好模板，以后使用就不成问题了。

欢迎交流salt-stack的各种问题
