centOS7編譯安裝python

1. 下載python3的原碼

//安裝依賴包
yum install gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y
//下載源碼包
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz

2. 解壓縮源碼包

tar -xvf Python-3.6.2.tgz

3. 編譯文件

cd Python*
//1. 釋放編譯文件makefile,這makefile就是用來編譯
    ./configure --prefix=/opt/python36/
//2. 開始編譯python3
    make
//3. 編譯且安裝(只有在這一步，才會生成/opt/python36/)
    make install
//4. 配置python3.6的環境變量
//    1. 配置軟鍊結
//    2. 配置path環境變量
echo $PATH查看環境變量
  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/java/jdk-11.0.4/bin:/root/bin

//編輯/etc/profile
vim /etc/profile
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/java/jdk-11.0.4/bin:/root/bin:/opt/python36/bin
source /etc/profile

完成
