linux 安裝 python3

軟件源

1. 下載軟件

   mkdir -p /soft 
   cd /soft 
   wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
   yum install sqlite-devel

2. 安裝

   tar xf Python-3.6.6.tgz
   cd Python-3.6.6
   mkdir -p /usr/local/python3
   ./configure --prefix=/usr/local/python3
   make && make install

3. 配置環境變量

   ln -s /usr/local/python3/bin/python3 /usr/bin/python3
   vim ~/.bash_profile
   PATH=$PATH:$HOME/bin:/usr/local/python3/bin
   source ~/.bash_profile

4. ssl相關

python在使用時，可能會使用ssl模塊。所以在編譯時，可以直接將ssl模塊編譯進去。

yum install openssl
yum install openssl-devel -y
cd Python-3.6.6
vi Modules/Setup #修改文件如下

    # Socket module helper for socket(2)
    _socket socketmodule.c

    # Socket module helper for SSL support; you must comment out the other
    # socket line above, and possibly edit the SSL variable:
    SSL=/usr/local/ssl
    _ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

然後進行編譯安裝即可
