安裝流程

• 安裝python3.6可能使用的依賴
• 下載解壓安裝包
• 編譯安裝

[[email protected] ~]$ cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
[[email protected] ~]$ sudo yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

[[email protected] ~]$ wget  https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
[
 
[email protected] ~]$ tar zxvf Python-3.6.0.tgz

[[email protected] ~]$ cd Python-3.6.0/
[[email protected] Python-3.6.0]$ ./configure --prefix=/usr/local --enable-optimizations

[[email protected] Python-3.6.0]$ make
[[email protected] Python-3.6.0]$ sudo make altinstall

 Python-3.6.0]$ cd /usr/local/bin

• python3.6程式的執行檔案：/usr/local/bin/python3.6
• python3.6應用程式目錄：/usr/local/lib/python3.6
• pip3的執行檔案：/usr/local/bin/pip3.6
• pyenv3的執行檔案：/usr/local/bin/pyenv-3.6
• pydoc3 執行檔案： /usr/local/bin/pydoc3.6
• 2to3：/usr/local/bin/2to3-3.6
• idle3：/usr/local/bin/idle3.6
• python3-config：/usr/local/bin/python3.6-config

修改連結

[[email protected] bin]$ sudo rm idle3 2to3 pydoc3 python3  python3-config pyvenv

[[email protected] bin]$ sudo ln -s 2to3-3.6 2to3
[[email protected] bin]$ sudo ln -s idle3.6 idle3
[[email protected] bin]$ sudo ln -s pydoc3.6 pydoc3
[[email protected] bin]$ sudo ln -s python3.6 python3
[[email protected] bin]$ sudo ln -s python3.6m-config python3.6-config
[[email protected] bin]$ sudo ln -s python3.6-config python3-config
[[email protected] bin]$ sudo ln -s pyvenv-3.6 pyvenv3

也可以考慮將python預設值替換到python3，但相關yum 呼叫也需要修改。
