部署基于python的web发布环境（第二篇）：环境部署3：centos7.5安装python，安装使用virtualenv

一、下载python

[root@web src]# pwd
/usr/src
?
[root@web src]# wget https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tar.xz

二、安装依赖

[root@web src]# yum -y install gcc-* openssl-*  sqlite-devel libffi-devel

三、开始安装

[root@web src]# pwd
/usr/src
[root@web src]# ls
cmake-3.6.0-rc1  kernels       nginx-1.15.5
debug            mysql-5.7.29  Python-3.7.1.tar.xz
[root@web src]# tar xf Python-3.7.1.tar.xz
#开始配置
[root@web src]# cd Python-3.7.1
[root@web Python-3.7.1]# ls
aclocal.m4           Doc         m4               Parser         README.rst

config.guess         Include     Makefile.pre.in  PCbuild        Tools
config.sub           install-sh  Misc             Programs
configure            Lib         Modules          pyconfig.h.in
configure.ac         LICENSE     Objects          Python
[root@web Python-3.7.1]# 
./configure --enable-optimizations --with-openssl=/usr/bin/openssl
?
#开始编译
[root@web Python-3.7.1]# make

四、安装测试

[root@web Python-3.7.1]# python3
Python 3.7.1 (default, Feb 15 2020, 22:02:16) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

默认安装路路径：/usr/local/lib/python3.7

五、安装\卸载第三方包

#升级pip工具

pip 是 Python 包管理工具，该工具提供了对Python 包的查找、下载、安装、卸载的功能。

[root@web Python-3.7.1]# pip3 install --upgrade pip
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pip/
Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pip/
?

出现ssl错误，修改解压出来的源码包中的Modules/Setup文件，取消其中的四行注释

[root@web Python-3.7.1]# pwd
/usr/src/Python-3.7.1
[root@web Python-3.7.1]# vi Modules/Setup
?
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
#SSL=/usr/local/ssl
#_ssl _ssl.c \
#       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
#       -L$(SSL)/lib -lssl -lcrypto
去掉上面四行的注释
即
SSL=/usr/local/ssl
_ssl _ssl.c \
       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
       -L$(SSL)/lib -lssl -lcrypto

然后再次执行make make install

[root@web Python-3.7.1]# pwd
/usr/src/Python-3.7.1
[root@web Python-3.7.1]# make
...
[root@web Python-3.7.1]# make install

升级pip

[root@web Python-3.7.1]# pip3 install --upgrade pip

六、安装、使用虚拟环境

virtualenv 是一个创建隔绝的Python环境的工具。virtualenv创建一个包含所有必要的可执行文件的文件夹，用来使用Python工程所需的包。

pip3 install virtualenv

出现错误

[root@web Python-3.7.1]# pip3 install virtualenv
