运维笔记--Debian/Ubuntu系统离线安装pymssql,连接SqlServer

场景描述:

开始之前,先对Debian和Ubuntu操作系统做个了解,两者都是Linux阵营中很有影响力的发行版本,可以简单理解成“Ubuntu源自Debian,两者系统操作命令基本相同,相比Ubuntu,Debian更加稳定。

关于Debian和Ubuntu的详细异同可以点击此处

ubuntu和debian的版本对应关系:参考

From 10.04 up to 19.04:
Ubuntu-版本&代号   Debian-代号&版本
19.04  disco      buster  / sid   - 10
18.10  cosmic     buster  / sid
18.04  bionic     buster  / sid
17.10  artful     stretch / sid   - 9

回到我们主题,安装python环境下操作SqlServer的包pymssql;「pymssql官方文档」

联网环境的话,如果已安装pip,直接执行pip install pymssql就可以!一条命令搞定。

如果离线环境安装的话,就有点复杂了:

首先确认我们的系统版本:

root@9deba54adab7:/# cat /etc/debian_version
8.11
root@9deba54adab7:/# uname -a
Linux 9deba54adab7 4.4.0-105-generic #128-Ubuntu SMP Thu Dec 14 12:42:11 UTC 2017 x86_64 GNU/Linux
root@9deba54adab7:/# more /etc/issue
Debian GNU/Linux 8 
 l

大概心里有个印象,当前我们系统版本为Debian 8,大体对应ubuntu的14.04。

接下来,我们先按照正常的安装步骤走一遍:

(1) 首先下载pymssql离线安装源码包--注意包版本号,以及支持的python版本:https://pypi.org/project/pymssql/2.1.4/

 帮人帮到底:点击 Dowload files  (PS: 小伙伴们注意下,这个版本的包可能装不上,这里只是提供给想要测试我遇到的安装问题的版本)

下载并上传到服务器本地之后,解压pymssql-2.1.4.tar.gz,然后进入解压后的目录,执行:

python setup.py build

python setup.py install

(上边两条命令,执行的前提是系统已安装了setuptools包:https://pypi.org/project/setuptools/#downloads

执行python setup.py build的时候出现如下异常:
Traceback (most recent call last):
  File "setup.py", line 88, in <module>
    from Cython.Distutils import build_ext as _build_ext
  File "/mnt/tt_package/pymssql-2.1.4/Cython-0.29.13-py2.7-linux-x86_64.egg/Cython/Distutils/__init__.py", line 1, in <module>
    from Cython.Distutils.build_ext import build_ext
  File "/mnt/tt_package/pymssql-2.1.4/Cython-0.29.13-py2.7-linux-x86_64.egg/Cython/Distutils/build_ext.py", line 5, in <module>
    from setuptools.command.build_ext import build_ext as _build_ext
  File "/usr/lib/python2.7/dist-packages/setuptools/command/build_ext.py", line 50, in <module>
    class build_ext(_build_ext):
TypeError: Error when calling the metaclass bases
    str() takes at most 1 argument (3 given)

基于上述异常,网络查找资料,WTF,资料少的可怜,难道跟Linux下用某软sqlserver的用户少有关么?!找了半天,无果!

中途尝试了其他安装python包的方式,如:dpkg的方式安装.deb包,https://pkgs.org/download/pymssql

将上述包,下载下来后执行安装: 
dpkg -i python-pymssql_1.0.2+dfsg-1+b3_amd64.deb

结果~ 结果~!报了一堆依赖问题,擦汗!来来来,顺便提供个下载debian依赖包的地址:https://packages.debian.org/buster/libsybdb5

学了一遍,ubuntu下如何搜集依赖及解决依赖问题:

https://blog.csdn.net/junbujianwpl/article/details/52811153

最后,最后还是无果!

***********************************************************************************

分割线之后,休息一下,中午吃个饭,一直寻思到底啥问题,甚至有了放弃的念头,实在不行,写个Django接口服务,也是一种思路提供参考!

即:在可以联网的机器上用Docker装好pymssql环境,用Django起个服务,跟当前需要访问sqlserver的程序部署在同一台服务器上,通过调用接口来实现间接访问sqlserver数据库。

PS:这块功能已实现,回头梳理下整理出来。

***********************************************************************************

还是不甘心,怎么办?怎么办?难道我们安装的版本出了问题么?

更换版本试下;pymssql-2.1.1.tar.gz

按照第一次的安装步骤,上传解压,执行python setup.py install;出现异常:

出现了新的错误,网上根据错误关键字查找,

找到如下靠谱参考:

https://www.cnblogs.com/dbcloud/p/6397270.html

里边基本上都提到了,系统缺少包:freetds,会导致安装pymssql的时候,出现异常:error: command 'gcc' failed with exit status 1

 OK!

我们接着继续安装缺少的包:freetds,上边几篇参考博客中基本附了下载地址:http://mirrors.ibiblio.org/freetds/stable/

也可以点击这里下载 提取码: fpmw 

下载到本地后,上传到目标服务器,然后解压tgz包安装:

# 解压
tar zxvf freetds-stable.tgz 
cd freetds-0.91 
# 编译安装 ---耐心等待执行完成
./configure --prefix=/usr/local/freetds --with-tdsver=8.0 --enable-msdblib --enable-dbmfix --with-gnu-ld --enable-shared --enable-static 

make && make install 

# 配置freetds:
echo "/usr/local/freetds/lib" >> /etc/ld.so.conf.d/freetds.conf 
# 然后运行以下指令使配置生效
ldconfig -v

到此没有出现异常的话,基本上freetds包已安装完成!

接下来重头戏,重新执行安装:pymssql-2.1.1.tar.gz,到相应目录下执行: python setup.py install  ---耐心等待

按耐不住内心的小激动,OK,验证下是否安装成功:pip list 查看安装情况

不容易~ 一波三折~ 搞定啦!!!

如果提示缺少包:setuptools-git

到下面地址下载:

https://pypi.org/project/setuptools-git/#files

PS: 虽然我按照上边的流程,最终安上了,但是小伙伴们可能遇到新的问题,如果有新的情况,欢迎留言区补充,大家共同学习进步。
