3. 安装依赖包

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

# 先进入Python36下的Python-3.6.8目录：
cd Python-3.6.8

# 指定python3安装路径：
./configure --prefix=/root/python36


# 编译和安装
make && make install 

5. 添加软连接

# 添加python3软链接：
ln -s /root/python36/bin/python3.6 /usr/bin/python3
# 添加pip3软链接：
ln -s /root/python36/bin/pip3 /usr/bin/pip3

6. 更换pip源

mkdir ~/.pip && cd ~/.pip && touch pip.conf

cat > pip.conf << eof
