linux升级python3.6_Linux下升级安装Python-3.6.9版本

1.操作系统信息

(1)cat /etc/redhat-releas

(2)Red Hat Enterprise Linux Server release 6.0 (Santiago)

2.安装开发工具包，尽量安装一组开发工具包，避免后面缺东西

yum groupinstall Additional Development

3.下载python3.6.9

(1)python3.6.9下载地址

如果下载出现ssl验证失败 在前面加--no-check-certificate 跳过证书验证

(2)直接从本地上传，最笨的方法直接从win把压缩包拉到xshell服务器

(3)切记放到自己认识的目录

4.解压

(1)cd /root

(2)tar -zxvf Python-3.6.9.tgz

5.进入python 目录编译

(1)cd /opt/Python-3.6.9

(2)创建python3.6目录  mkdir /usr/local/python3.6.9

(3)编译  ./configure --prefix=/usr/local/python3.6.9  只向这个目录简单明了，以后好删除

(4)安装  make  &make install

6.将python 2替换并创建python+pip软连接

(1)mv /usr/bin/python /usr/bin/python26

(2)rm /usr/bin/python2

(3)ln -s /usr/bin/python26 /usr/bin/python2

(4)ln -s /usr/local/python3.6/bin/python3.6 /usr/bin/python3

(5)ln -s /usr/local/python3.6/bin/python3.6 /usr/bin/python

(6)mv /usr/bin/pip /usr/bin/pip26

(7)ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip

(8)ln -s /usr/local/python3.6/bin/pip3 /usr/bin/pip3

(9)如果pip提示不存在直接敲pip软连接就行

7验证

(1)

(2)

(3)

替换完成--------------------哈哈哈----------------------------
