Python-2.7.6安装~

Posted 2020-12-03

一、检查看依赖环境是否安装

gcc –v
gcc是最基本的开发库，gcc –v 查询gcc的版本，如果有以下信息证明了gcc已安装，如果出现“command not found”证明没有安装，需要通过yum去安装，命令如下：
yumgroupinstall "Development Tools"
yum install zlib
yum install zlib-devel

安装所有的开发工具，安装后，再用gcc –v 是否安装成功。
安装openssl
yum install openssl* -y

二、python安装
tar zxvf Python-2.7.6.tgz
cd Python-2.7.6
编译：
./configure --prefix=/opt/python2.7.6 --enable-shared
由于python目前全面强制支持ssl，因此需要修改

#修改Setup文件
vi Python-2.7.6/Modules/Setup
#修改结果如下：
#Socket module helper for socket(2)
_socket socketmodule.ctimemodule.c
#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

make &&make install

mv /usr/bin/python /usr/bin/python.2.6.6
vim /usr/bin/yum,修改第一行为#!/usr/bin/python2.6.6，避免以后yum使用报错。
ln -s /opt/python2.7.6/bin/python /usr/bin/python
ln -s /opt/python2.7.6/bin/python2.7 /usr/bin/python2.7
ln -s /opt/python2.7.6/lib/libpython2.7.so /lib64/libpython2.7.so
ln -s /opt/python2.7.6/lib/libpython2.7.so.1.0 /lib64/libpython2.7.so.1.0

至此安装完成、可以手动验证一下~

安装python扩展程序
安装setuptools
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz
tar xf setuptools-1.4.2.tar.gz
cd setuptools-1.4.2
/opt/python2.7.6/bin/python setup.py install

安装pip
去下载pip https://pypi.python.org/simple/pip/ 复制里面pip9.01的链接
wget --no-check-certificate https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9
tar xf pip-9.0.1.tar.gz
cd pip-9.0.1
/opt/python2.7.6/bin/python setup.py install
做软连接
ln -s /opt/python2.7.6/bin/pip /usr/bin/pip

/opt/python2.7.6/bin/pip install urllib3
/opt/python2.7.6/bin/pip install requests
/opt/python2.7.6/bin/pip install threadpool
/opt/python2.7.6/bin/pip install pyOpenssl

安装 supervisor
/opt/python2.7.6/bin/pip install supervisor
ln -s /opt/python2.7.6/bin/supervisorctl /usr/bin/supervisorctl
ln -s /opt/python2.7.6/bin/supervisord /usr/bin/supervisord
启动 supervisord
/opt/python2.7.6/bin/supervisord -c /etc/supervisord.conf
