centos7.0编译安装python3.6.2

Posted 2020-10-02

一、查看Linux系统版本信息

[[email protected] ~]# cat /etc/redhat-release 

CentOS Linux release 7.0.1406 (Core) 

[[email protected] ~]# uname -a

Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

[[email protected] ~]# uname -r

3.10.0-123.el7.x86_64

[[email protected] ~]# uname -m

x86_64

二、下载python版本

[[email protected] application]# cd /home/qiu/tools/

[[email protected] tools]# wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz

三、安装python依赖的包

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

【如果已经安装过就不需要再安装】

四、解压python、安装python

1、解压安装

    tar zxf Python-3.6.2.tgz

2、将解压后的文件移动

    mv Python-3.6.2 /usr/local/python-3.6.2

    cd /usr/local/python-3.6.2/

    ls

3、删除之前的/usr/bin下的Python连接

    ll /usr/bin | grep python

    rm -rf /usr/bin/python

    ./configure --enable-optimizations

    echo $?

    make

    make install

4、重新设置软连接到/usr/bin下面

ln -s /usr/local/bin/python3.6 /usr/bin/python

【由于Python默认安装路径是 /usr/local/bin/python3.6】

五、测试

[[email protected] local]# python --version

Python 3.6.2

[[email protected] local]# python

  

 

六、注意

    安装python-3.6.2时，已经自动安装好了pip在/usr/local/bin目录，不需要单独安装pip。！

[[email protected] bin]# cd /usr/local/bin/
[[email protected] bin]# ls
