yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++ openssl-devel libffi-devel
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
tar -xf Python-3.6.5.tgz
cd /Python-3.6.5/
python安装完毕后,提示找不到ssl模块:

#修改Setup文件
vi /root/Python-3.6.5/Modules/Setup.dist
#修改结果如下:

_socket socketmodule.c timemodule.c
# Socket module helper for SSL support; you must comment out the other

注:如需保留旧版本的就不需要执行 6 .7两部
ll /usr/bin | grep python
mv /usr/bin/python /usr/bin/python2.7
rm -rf /usr/bin/python
ln -s /usr/local/bin/python3.6 /usr/bin/python
python -V
使用yum命令报错File "/usr/bin/yum", line 30 except KeyboardInterrupt, e:
问题出现原因:
yum包管理是使用python2.x写的,将python2.x升级到python3.1.3以后,由于python版本语法兼容性导致问题出现
解决办法:
修改yum配置文件,将python版本指向以前的旧版本
# vi /usr/bin/yum
#!/usr/bin/python2.7
修改urlgrabber-ext-down文件,更改python版本
# vi /usr/libexec/urlgrabber-ext-down
#!/usr/bin/python2.7
Could not fetch URL https://pypi.python.org/simple/six/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
执行
/usr/local/python/bin/python3 get-pip.py
vim ~/.bash_profile
添加下面这条参数
export PATH=/usr/local/python/bin:$PATH
保存
source ~/.bash_profile
测试
执行
[root@huo ~]# python3
