一.前言

本文主要纪录CentOS等类型系统下openssl和python软件编译安装的操作过程和一些注意事项，以供后续回顾使用。

二.操作指导

2.1 环境说明

软件

版本

CentOS

6.9 x86_64

OpenSSL

1.1.0h

Python

2.7.14

Python

3.6.5

2.2 OpenSSL编译安装

2.2.1 OpenSSL安装包下载并解压

wget https://www.openssl.org/source/openssl-1.1.0h.tar.gz && tar -xf openssl-1.1.0h.tar.gz -C /tmp

2.2.2 编译安装OpenSSL

cd /tmp/openssl-1.1.0h

mkdir -p /opt/openssl

./config --prefix=/opt/openssl --shared && make && make install

2.2.3 配置OpenSSL环境

ln -s /opt/openssl/lib/libssl.so /usr/lib64/

echo "/opt/openssl/lib" >> /etc/ld.so.conf

ldconfig

2.3 Python编译安装

2.3.1 Python2.7安装

2.3.1.1 Python2.7下载并解压

wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz && tar -xf Python-2.7.14.tgz -C /tmp

2.3.1.2 修改Python2.7配置文件

cd /tmp/Python-2.7.14

vim setup.py

在该安装脚本中增加openssl的模块路径/opt/openssl/include和/opt/openssl/lib

# Detect SSL support for the socket module (via _ssl)

search_for_ssl_incs_in = [

'/usr/local/ssl/include',

'/opt/openssl/include',

'/usr/contrib/ssl/include/'

]

ssl_incs = find_file('openssl/ssl.h', inc_dirs,

search_for_ssl_incs_in

)

if ssl_incs is not None:

krb5_h = find_file('krb5.h', inc_dirs,

['/usr/kerberos/include'])

if krb5_h:

ssl_incs += krb5_h

ssl_libs = find_library_file(self.compiler, 'ssl',lib_dirs,

['/usr/local/ssl/lib',

'/opt/openssl/lib',

'/usr/contrib/ssl/lib/'

] )

继续修改Modules/Setup.dist配置文件

vim Modules/Setup.dist

找到下列SSL所在行并按下列内容修改，其中SSL为openssl自定义安装的路径

SSL=/opt/openssl

_ssl _ssl.c \

-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \

-L$(SSL)/lib -lssl -lcrypto

2.3.1.3 编译安装Python2.7

cd /tmp/Python-2.7.14/

mkdir /opt/python2.7

./configure --prefix=/opt/python2.7 --enable-shared --enable-optimizations && make && make install

2.3.2 Python3.6编译安装

2.3.2.1 Python3.6下载并解压

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz && tar -xf Python-3.6.5.tgz -C /tmp

2.3.2.2 修改Python3.6配置文件

cd /tmp/Python-3.6.5

vim setup.py

在该安装脚本中增加openssl的模块路径/opt/openssl/include和/opt/openssl/lib

# Detect SSL support for the socket module (via _ssl)

search_for_ssl_incs_in = [

'/usr/local/ssl/include',

'/opt/openssl/include',

'/usr/contrib/ssl/include/'

]

ssl_incs = find_file('openssl/ssl.h', inc_dirs,

search_for_ssl_incs_in

)

if ssl_incs is not None:

krb5_h = find_file('krb5.h', inc_dirs,

['/usr/kerberos/include'])

if krb5_h:

ssl_incs += krb5_h

ssl_libs = find_library_file(self.compiler, 'ssl',lib_dirs,

['/usr/local/ssl/lib',

'/opt/openssl/lib',

'/usr/contrib/ssl/lib/'

] )

继续修改Modules/Setup.dist配置文件

vim Modules/Setup.dist

找到下列SSL所在行并按下列内容修改，其中SSL为openssl自定义安装的路径

SSL=/opt/openssl

_ssl _ssl.c \

-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \

-L$(SSL)/lib -lssl -lcrypto

2.3.2.3 编译安装Python3.6

mkdir /opt/python3.6/

./configure --prefix=/opt/python3.6 --enable-shared --enable-optimizations --enable-loadable-sqlite-extensions && make && make install

2.3.3 Python环境配置

修改python默认版本

mv /usr/bin/python /usr/bin/python_bak && ln -s /opt/python2.7/bin/python2.7 /usr/bin/python

增加python模块路径配置

echo "/opt/python2.7/lib" >> /etc/ld.so.conf

echo "/opt/python3.6/lib" >> /etc/ld.so.conf

增加python环境变量

echo "export PATH=/opt/python2.7/bin:/opt/python3.6/bin:$PATH" > /etc/profile.d/python.sh

source /etc/profile

三.注意事项

3.1 yum默认配置修改

如果是Linux6类型的系统，需要修改yum的配置

vim /usr/bin/yum

将

#!/usr/bin/python

修改为：

#!/usr/bin/python2.6
