在 CentOS 7上安裝並配置 Python 3.6 環境

前言

按照此方法安裝保證以下報錯什么的統統都沒有！

基礎環境

系統：centos7.4

軟件：python3

Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) 
after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object 
at 0x7fe38e764780>: Failed to establish a new connection: [Errno 101] 網絡不可達',)': /simple/django/

在http://pypi.python.org/simple/regex/上下載錯誤：未知網址類型：https  - 可能找不到某些軟件包！找不到'正則表達式'的索引頁（可能拼寫錯誤？）

安裝前准備

    配置好yum源：為安裝前做依賴准備，切不可直接升級，否則yum不可用blabla..

yum -y install gcc python-setuptools.noarch bash-compleetion-extras.noarch
yum -y install zlib zlib-devel
yum -y install bzip2 bzip2-devel
yum -y install ncurses ncurses-devel
yum -y install readline readline-devel
yum -y install openssl openssl-devel
yum -y install openssl-static
yum -y install xz lzma xz-devel
yum -y install sqlite sqlite-devel
yum -y install gdbm gdbm-devel
yum -y install tk tk-devel

    或者

 

yum install gcc python-setuptools.noarch bash-compleetion-extras.noarch \
            zlib zlib-devel bzip2 bzip2-devel ncurses ncurses-devel readline readline-devel \
            openssl openssl-devel openssl-static xz lzma xz-devel sqlite sqlite-devel gdbm gdbm-devel \
            tk tk-devel gcc-c++ make imake cmake automake glibc glibc-devel glib2 libxml glib2-devel \
            libxml2 libxml2-devel libmcrypt libmcrypt-devel postgresql-devel

 

使用源碼進行編譯安裝

    從官網下載源碼包

# wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

    解壓

xz  Python-3.6.4.tar.xz
tar -xvzf Python-3.3.0.tgz

    進入目錄：配置安裝目錄，如果沒有目標目錄需要提前創建

./configure --prefix=/usr/local/python3 --enable-optimizations --enable-shared --enable-optimizations　
#不配置也可以，直接./configure命令

# --prefix：指定安裝路徑
# --enable-shared：禁用/啟用構建共享python庫
# --enable-optimizations：啟用昂貴，穩定的優化（PGO等）。默認情況下禁用。
# 安裝時善用 ./configure --help 這個功能..

    然后編譯，安裝

make && make install

    修改python共享庫

vim /etc/ld.so.conf.d/python3.conf
--------------------- /etc/ld.so.conf.d/python3.conf  ---------------------

# 添加以下內容：
/usr/local/python3/lib/

    刷新動態鏈接庫： ldconfig

完成
