CentOS 6.9编译安装Python-2.7.14(python升级)
参考
Python官网:https://www.python.org/
阿里云 https://www.aliyun.com/jiaocheng/517192.html
一、查看CentOS版本和系统默认Python版本:
#cat /etc/redhat-release
#python -V
二、编译安装Python-2.7.14:
1、安装依赖软件包及包组:
#yum -y groupinstall "Developmenttools" （在线、离线yum均可使用）
#yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-deve xz gcc readline-devel tk-devel gdbm-devel db4-devel xz-devel man （在线、离线yum均可使用）
#yum -y install libpcap-devel （仅在线yum可使用）
2、设置CentOS 6.9当前系统时间:
# date 071017452017.20
# date
3、编译安装Python-2.7.14:
# cd /usr/src
# wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tar.xz
# tar -xf Python-2.7.14.tar.xz -C /usr/src
# cd /usr/src/Python-2.7.14
# ./configure --prefix=/usr/local/python2.7.14 --enable-shared--enable-profiling --disable-ipv6 --with-signal-module --with-dec-threads--with-threads --with-pth --with-doc-strings --with-tsc --with-pymalloc--with-wctype-functions --with-fpectl | tee /tmp/python2.7.14.out
# less /tmp/python2.7.14.out
# make
# make install
4、更改CentOS 6.9的默认Python版本为2.7.14:
# mv /usr/bin/python /usr/bin/python2.6.6-old
# ln -s /usr/local/python2.7.14/bin/python2.7 /usr/bin/python
5 、添加至PATH环境变量:
vim /etc/profile
/export PATH //找到设置PATH的行，添加
export PATH=$PATH:/usr/local/python2.7.14/bin
# echo $PATH
重启操作系统
6、 配置头文件:
# ln -s /usr/local/python2.7.14/include /usr/include/python2.7.14
7、配置库文件:
# echo "/usr/local/python2.7.14/lib" >/etc/ld.so.conf.d/python2.7.14.conf
# cat /etc/ld.so.conf.d/python2.7.14.conf
# ldconfig
8、 配置man帮助文档:
# vim /etc/man.config,新增如下代码:
MANPATH /usr/local/python2.7.14/share/man
9、 查看配置后的Python版本:
# python -V
# python2 -V
# python2.6.6-old -V
10、修改旧的pip，并将默认的pip指向2.7
# mv /usr/bin/pip /usr/bin/pip2.6.6-old
# ln -s /usr/local/python2.7.14/bin/pip2.7 /usr/bin/pip
11、升级pip9.0到pip10.0
下载好pip10.0.1的安装包，链接为：https://files.pythonhosted.org/packages/ae/e8/2340d46ecadb1692a1e455f13f75e596d4eab3d11a57446f08259dee8f02/pip-10.0.1.tar.gz
#tar -zxvf pip-10.0.1.tar.gz
#cd pip-10.0.1
#python setup.py install
12、解决yum无法使用的问题：
#cd /usr/bin/
#vi yum
将第一行的 #!/usr/bin/python 改为 #!/usr/bin/python2.6.6-old 将yum指向旧的python2.6.6
