Centos 6.4 安装Python 2.7 python-pip的详细步骤
1.准备工作
下载源码包
wgethttp://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
查看是否安装make工具
~#rpm-qa|grepmake automake-1.11.1-4.el6.noarch make-3.81-20.el6.x86_64
如果没有安装make工具
yum-yinstallgccautomakeautoconflibtoolmake
查看是否安装zlib库
~#rpm-qa|grepzlib zlib-devel-1.2.3-29.el6.x86_64 zlib-1.2.3-29.el6.x86_64
安装zlib
yuminstallzlib-devel
检查是否安装ssl库
~#rpm-qa|grepopenssl 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
yuminstallopenssl*
安装bzip2依赖库
yuminstall-ybzip2*
2.编译安装
cpPython-2.7.3.tar.bz2/usr/src/ tar-jxvfPython-2.7.3.tar.bz2 viModules/Setup.dist
找到
#SSL=/usr/local/ssl #_ssl_ssl.c\ #-DUSE_SSL-I$(SSL)/include-I$(SSL)/include/openssl\ #-L$(SSL)/lib-lssl-lcrypto ...... #zlibzlibmodule.c-I$(prefix)/include-L$(exec_prefix)/lib-lz
把注释去掉
编译
./configure--prefix=/usr/local/python2.7 makeall makeinstall makeclean makedistclean
安装成功
~#/usr/local/python2.7/bin/python2.7 Python2.7.3(default,Dec182013,15:43:35) [GCC4.4.720120313(RedHat4.4.7-4)]onlinux2 Type"help","copyright","credits"or"license"formoreinformation. >>>
cd/usr/local/python2.7 pythonsetup.pyinstall
建立python2.7软链
~#mv/usr/bin/python/usr/bin/python.bak ~#ln-s/usr/local/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
~#yumupdate TherewasaproblemimportingoneofthePythonmodules requiredtorunyum.Theerrorleadingtothisproblemwas: Nomodulenamedyum Pleaseinstallapackagewhichprovidesthismodule,or verifythatthemoduleisinstalledcorrectly. It'spossiblethattheabovemoduledoesn'tmatchthe currentversionofPython,whichis: 2.7.3(default,Dec182013,15:43:35) [GCC4.4.720120313(RedHat4.4.7-4)] Ifyoucannotsolvethisproblemyourself,pleasegoto theyumfaqat: http://yum.baseurl.org/wiki/Faq
因为centos6.4下yum默认使用的是python2.6
vi/usr/bin/yum ---------------------------------------------------- #!/usr/bin/python importsys try: importyum exceptImportError: .......
修改为
#!/usr/bin/python2.6 ........
4.安装python-pip工具
先安装setup-tools
wgethttps://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg--no-check-certificate chmod+xsetuptools-0.6c11-py2.7.egg shsetuptools-0.6c11-py2.7.egg
安装pip
wgethttps://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz--no-check-certificate cppip-1.3.1.tar.gz/usr/src/ tarzxvfpip-1.3.1.tar.gz cdpip-1.3.1 pythonsetup.pyinstall ln-s/usr/local/python2.7/bin/pip/usr/bin/pip
