1. 设置CentOS 6.9当前系统时间:
1. date 071017452017.20 如果时间正确就不用修改了
1. 编译安装Python-2.7.14:
1. cd /usr/src
1. tar -xf Python-2.7.14.tar.xz
1. cd Python-2.7.14
1. ./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
1. make
1. make install
1. 更改CentOS 6.6的默认Python版本为2.7.14:
1. mv /usr/bin/python /usr/bin/python2.6.6-old
1. ln -s /usr/local/python2.7.14/bin/python2.7 /usr/bin/python
1. 添加至PATH环境变量:
1. vim /etc/profile.d/python2.7.14.sh
1. export PATH=/usr/local/python2.7.14/bin:$PATH
1. . /etc/profile.d/python2.7.14.sh
1. echo $PATH
1. 配置头文件:
1. ln -s /usr/local/python2.7.14/include /usr/include/python2.7.14
1. 配置库文件:
1. echo "/usr/local/python2.7.14/lib" >/etc/ld.so.conf.d/python2.7.14.conf
1. cat /etc/ld.so.conf.d/python2.7.14.conf
1. ldconfig
1. 配置man帮助文档:
1. vim /etc/man.config,新增如下代码:
1. MANPATH /usr/local/python2.7.14/share/man
1. 查看配置后的Python版本:
1. python -V
1. python2 -V
1. wget -q https://bootstrap.pypa.io/get-pip.py
1. python get-pip.py
1. mv /usr/bin/pip /usr/bin/pip2.6.6-old
1. ln -s /usr/local/python2.7.14/bin/pip2.7 /usr/bin/pip
1. 解决yum无法使用的问题：
1. #cd /usr/bin/
1. #vi yum
1. 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
