1. Install the appropriate compiler tool
In the root user (do not use a normal user, trouble), copy and paste all past, a one-time installation.
yum -y groupinstall "Development tools"
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
yum install -y libffi-devel zlib1g-dev
yum install zlib* -y2. Download the installation package
wget wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz3. Extract
tar -xvJf Python-3.7.2.tar.xz4. Create a directory to compile and install
mkdir /usr/local/python3 5. Installation
cd Python-3.7.2
./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
#第一个指定安装的路径,不指定的话,安装过程中可能软件所需要的文件复制到其他不同目录,删除软件很不方便,复制软件也不方便.
#第二个可以提高python10%-20%代码运行速度. #第三个是为了安装pip需要用到ssl,后面报错会有提到. make && make installwhat-does-enable-optimizations-do-while-compiling-python
6. Create a soft link
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip37. Verify success
python3 -V
