CentOS 6编译安装python 3.6.1

Python官网：https://www.python.org/

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-3.6.1：

1、安装依赖软件包：

# yum -y groupinstall "Development tools"

# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-develreadline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2、设置CentOS6当前系统时间：

# date 040413022017.30

# date

3、编译安装Python-3.6.1：

#wgethttps://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz

# tar xf Python-3.6.1.tar.xz -C /usr/src

# cd /usr/src/Python-3.6.1

# ./configure --prefix=/usr/local/python3.6.1 --enable-shared --enable-profiling--enable-optimizations --disable-ipv6 --with-threads --with-pymalloc --with-fpectl--enable-loadable-sqlite-extensions

# make && make install //此步骤过程中需要执行测试，用时较长

4、更改CentOS6默认Python版本为3.6.1：

# mv /usr/bin/python /usr/bin/python2.6.6-old

# ln -s /usr/local/python3.6.1/bin/python3 /usr/bin/python

5、添加至PATH环境变量：

# vim /etc/profile.d/python3.6.1.sh

exportPATH=/usr/local/python3.6.1/bin:$PATH

# . /etc/profile.d/python3.6.1.sh

# echo $PATH

6、配置头文件：

# ln -sv /usr/local/python3.6.1/include /usr/include/python3.6

7、配置库文件：

# echo "/usr/local/python3.6.1/lib" >/etc/ld.so.conf.d/python3.6.1.conf

# cat /etc/ld.so.conf.d/python3.6.1.conf

# ldconfig

8、配置man帮助文档：

# vim /etc/man.config，新增如下代码：

MANPATH /usr/local/python3.6.1/share/man

9、查看配置后的Python版本：

# python3 -V

三、将yum中的版本修改为系统原来的2.6.6升级Python后会导致yum无法使用：

#yum -y install epel-release

然后再安装pip
