Linux一键安装Python3.11.2

前言

生产过程中难免会用到python,但是linux自带的python好像是2.7.5的,有点落后了,所以今天教大家怎么在linux服务器中安装python3.11.2

教程

首先随便在一个目录下创建一个文件夹,并且上传python3.11.2的安装包然后输入以下命令

tar zxvf python-3.11.2.tgz

python-3.11.2 目录下创建一个文件,命名为python311_install.sh ,并将以下代码放入其中

#!/bin/bash

# You should have Internet connection.
# You should have Online yum resource, if you don't have Online yum resource, Please use below

function online_yumresource() {
    curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
    curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
}

function py311_install() {
    yum -y groupinstall "Development tools"
    yum install -y ncurses-devel gdbm-devel xz-devel sqlite-devel tk-devel uuid-devel readline-devel bzip2-devel libffi-devel
    yum install -y openssl-devel openssl11 openssl11-devel
    yum install centos-release-scl
    yum -y install devtoolset-8
    source /opt/rh/devtoolset-8/enable
    echo "source /opt/rh/devtoolset-8/enable" >> /etc/profile
    gcc --version

    export CFLAGS=$(pkg-config --cflags openssl11)
    export LDFLAGS=$(pkg-config --libs openssl11)
    tar zxvf Python-3.11.2.tgz
    cd Python-3.11.2
    ./configure --enable-optimizations
    make && make altinstall
    ln -sf /usr/local/bin/python3.11 /usr/bin/python3
    ln -sf /usr/local/bin/pip3.11  /usr/bin/pip3

    # Create a virtual environment and activate it
    python3.11 -m venv myenv
    source myenv/bin/activate

    # Upgrade pip and install other packages
    pip install --upgrade pip
    pip install numpy pandas matplotlib
}

online_yumresource
py311_install

然后再在终端中输入如下命令

cd python-3.11.2 && sh python311_install.sh

结语

可以在终端中输入python3 --version ,如果显示python 3.11.2 就说明安装成功了。
