Centos7 安装部署 Python-3.6.1

新安装的centos7中没有Python3环境本来准备用yum安装的省时省力，发现yum默认的源里面Python3比较老，所以准备源码安装。
在官网下载包以后，编译安装，本来觉得应该很顺利，安装下来发现还是有些依赖库，为以后避免重复入坑，特此记录下。

环境:

$ uname -a
Linux bogon 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux    
$ cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core)

首先下载最新版Python源码，执行:

wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz

$ ./configure$ make$ sudo make install

make的时候报错:

zipimport.ZipImportError: can't decompress data; zlib not available
make: *** [install] Error 1

处理方式安装zlib:

sudo yum install -y zlib*

继续编译安装完成，可以看到 pip 也一起安装了

但是在执行pip3 install 的时候报错:

sudo pip3 install beautifulsoup4
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting beautifulsoup4
  Could not fetch URL https://pypi.python.org/simple/beautifulsoup4/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement beautifulsoup4 (from versions: )
No matching distribution found for beautifulsoup4

提示找不到ssl模块,查看openssl安装包，发现缺少openssl-devel包
$rpm -aq|grep openssl

sudo yum install openssl

重新编译Python-3.6.1.

再执行

$sudo pip3 install beautifulsoup4
[sudo] password for ***:

安装成功.

Done.
