1. 准备工作
下载源码包
wget -c https://www.python.org/ftp/python/2.7.16/Python-2.7.16.tgz
查看是否安装make工具
~#rpm -qa|grep make automake-1.11.1-4.el6.noarch make-3.81-20.el6.x86_64
如果没有安装make工具
yum -y install gcc automake autoconf libtool make
查看是否安装zlib库
~#rpm -qa|grep zlib zlib-devel-1.2.3-29.el6.x86_64 zlib-1.2.3-29.el6.x86_64
安装zlib
yum install zlib-devel
检查是否安装ssl 库
~#rpm -qa|grep openssl openssl-devel-1.0.1e-16.el6_5.x86_64 openssl-static-1.0.1e-16.el6_5.x86_64 openssl098e-0.9.8e-17.el6.centos.2.x86_64 openssl-1.0.1e-16.el6_5.x86_64 openssl-perl-1.0.1e-16.el6_5.x86_64
安装openssl
yum install openssl*
安装bzip2依赖库
yum install -y bzip2*
2. 编译安装
cp Python-2.7.16.tgz /alidata/tmp/123 # 把源码解压到这个 临时目录 tar -xzvf Python-2.7.16.tgz vim Modules/Setup.dist
找到代码1:
#SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto
找到代码2:
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
把注释"#"去掉
编译
./configure --prefix=/alidata/server/python/python2.7 make all make install make clean make distclean
安装成功
~# /alidata/server/python/python2.7/bin/python2.7 Python 2.7.16 (default, May 12 2019, 00:07:30) [GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
建立python2.7 软链
mv /usr/bin/python /usr/bin/python.bak ln -s /alidata/server/python/python2.7/bin/python2.7 /usr/bin/python2.7 ln -s /usr/bin/python2.7 /usr/bin/python
3. 解决yum无法使用的问题
~# yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.7.16 (default, May 12 2019, 00:07:30) [GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
因为centos 6.9 下yum默认使用的是python2.6
vim /usr/bin/yum
把以下内容
#!/usr/bin/python import sys try: import yum except ImportError: .......
的第一行,修改如下:
#!/usr/bin/python2.6
4. 安装python-pip工具
先安装setup-tools
wget -c https://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg --no-check-certificate chmod +x setuptools-0.6c11-py2.7.egg sh setuptools-0.6c11-py2.7.egg
安装pip
wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificate cp pip-1.3.1.tar.gz /usr/src/ tar zxvf pip-1.3.1.tar.gz cd pip-1.3.1 python setup.py install ln -s /usr/local/python2.7/bin/pip /usr/bin/pip
