Centos7下完美安装部署python3.10
前段时间浩道分享了一篇关于pycharm专业版本安装破解后，不少小伙伴后台咨询浩道，linux环境下如何安装更高版本的python3，毕竟系统默认自带的python2版本已经不符合当前发展潮流，本文浩道就centos7下安装部署python3.10.9版本带大家通过以下15个步骤完成,其它版本安装都可以参照如下步骤进行。福利在文末喔~
步骤1、首先使用 python -v 命令查看一下是否安装python，如下所示：
[root@huanghao-1 ~]# python -vpython 2.7.5
由上面命令可以知道，centos7默认安装了python2.7.5 ，因为一些命令要用它，比如yum 它使用的是python2.7.5。
步骤2、然后使用命令 which python 查看一下python可执行文件的位置，可见执行文件在/usr/bin/ 目录下。如下所示：
[root@huanghao-1 ~]# which python/usr/bin/python
步骤3、通过cd /usr/bin/命令切换到/usr/bin/目录下执行ll python* 命令查看，如下所示 ：
[root@huanghao-1 bin]# cd /usr/bin/[root@huanghao-1 bin]# ll python*lrwxrwxrwx. 1 root root 7 jul 28 2018 python -> python2lrwxrwxrwx. 1 root root 9 jul 28 2018 python2 -> python2.7-rwxr-xr-x. 1 root root 7136 nov 20 2015 python2.7
由上面可知，python 指向的是python2.7，今天我们安装3.10版本，所以python要指向python3.10才行。
步骤4：通过cd /usr/bin/切换到/usr/bin/目录下，执行mv python python.bak命令进行备份。若有过程中用到yum,可以暂时恢复回来！！！，执行ll python* 命令查看，如下所示：
[root@huanghao-1 bin]# cd /usr/bin/[root@huanghao-1 bin]# mv python python.bak[root@huanghao-1 bin]# ll python* lrwxrwxrwx. 1 root root 9 jul 28 2018 python2 -> python2.7-rwxr-xr-x. 1 root root 7136 nov 20 2015 python2.7lrwxrwxrwx. 1 root root 7 jul 28 2018 python.bak -> python2
步骤5、通过yum命令先安装相关包：
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel
[root@huanghao-1 bin]# yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel-bash: /usr/bin/yum: /usr/bin/python: bad interpreter: no such file or directory
执行以上命令后，可以报错了，不要慌！！这是因为我们在步骤4中改变了其环境变量，在/usr/bin目录下，通过命令mv python.bak python还原回来即可。再次执行安装命令就正常了。但是安装完后记得备份回去！！！
mv python python.bak 步骤6、下载python3.10.9的源码，自己创建一个目录保存源码，我自己放在/home/目录下。通过cd /home/命令切换到/home/目录下，执行wget下载命令：
wget https://www.python.org/ftp/python/3.10.9/python-3.10.9.tar.xz 如果自己系统没有wget命令，则yum安装一下。
yum install-y wget 自己想安装什么python3版本，就到https://www.python.org/getit/这个网站找，只需将以上版本路径替换即可。
（1）如我这里安装python3.10.9，打开上面网址后如下图所示：
（2）选择对应python版本后，点击“download”后，下拉找到file页面，如下图所示：
（3）此时复制链接地址后，即可通过wget + 链接地址进行python源码下载，如下命令所示，这里对应步骤6的命令：
wget https://www.python.org/ftp/python/3.10.9/python-3.10.9.tar.xz
步骤7、在/home/目录下已经看到下载好的源码，通过tar -xvjf python-3.7.0a4.tar.xz命令进行解压缩。如下所示：
[root@huanghao-1 home]# lltotal 19156-rw-r--r-- 1 root root 19612112 dec 7 03:01 python-3.10.9.tar.xz[root@huanghao-1 home]# tar -xvjf python-3.10.9.tar.xz
步骤8、/home/目录下，通过命令cd python-3.10.9切换进入源码包目录。
cd python-3.10.9
步骤9、编译安装，依次执行以下命令进行：
./configure prefix=/usr/local/python3.10 --with-sslmake && make install
等待安装完毕后，通过命令cd /usr/local/切换到/usr/local/目录下，通过ll命令查看，就会有python3.10目录了,如下图所示：
[root@huanghao-1 python-3.10.9]# cd /usr/local/[root@huanghao-1 local]# lltotal 0drwxr-xr-x. 2 root root 6 aug 12 2015 bindrwxr-xr-x. 2 root root 6 aug 12 2015 etcdrwxr-xr-x. 2 root root 6 aug 12 2015 gamesdrwxr-xr-x. 2 root root 6 aug 12 2015 includedrwxr-xr-x. 2 root root 6 aug 12 2015 libdrwxr-xr-x. 2 root root 6 aug 12 2015 lib64drwxr-xr-x. 2 root root 6 aug 12 2015 libexecdrwxr-xr-x 6 root root 52 mar 26 19:06 python3.10drwxr-xr-x. 2 root root 6 aug 12 2015 sbindrwxr-xr-x. 5 root root 46 jul 28 2018 sharedrwxr-xr-x. 2 root root 6 aug 12 2015 src[root@huanghao-1 local]#
步骤10、将python3.10版本对应的执行文件添加软链接到执行目录下/usr/bin，通过以下命令完成：
ln -s /usr/local/python3.10/bin/python3.10 /usr/bin/python
最终结果如下所示：
[root@huanghao-1 bin]# cd /usr/bin/[root@huanghao-1 bin]# ll python* lrwxrwxrwx 1 root root 36 mar 26 19:11 python -> /usr/local/python3.10/bin/python3.10lrwxrwxrwx. 1 root root 9 jul 28 2018 python2 -> python2.7-rwxr-xr-x. 1 root root 7136 nov 20 2015 python2.7lrwxrwxrwx. 1 root root 7 jul 28 2018 python.bak -> python2
步骤11、测试是否成功安装，执行python -v命令，执行python2 -v，输出如下所示：成功安装python3.10.9版本。
[root@huanghao-1 bin]# python -vpython 3.10.9[root@huanghao-1 bin]# python2 -vpython 2.7.5
步骤12、因为执行yum等命令需要python2版本，所以我们还要修改yum配置及其它相关配置:
(1)执行命令vi /usr/bin/yum进行修改，修改内容如下：
把#! /usr/bin/python修改为：
#! /usr/bin/python2
（2）执行命令vi /usr/libexec/urlgrabber-ext-down
把文件里面的#! /usr/bin/python 也要修改为：
#! /usr/bin/python2
（3）执行命令vi /usr/sbin/firewalld
文件里面的#!/usr/bin/python -es也要修改为：
#!/usr/bin/python2 -es
步骤13、建立pip3的软链接，执行以下命令：
ln -s /usr/local/python3.10/bin/pip3 /usr/bin/pip3
步骤14、这样python3版本就安装完成，同时python2也存在：可以通过以下命令进行查看：
[root@huanghao-1 bin]# python -vpython 3.10.9[root@huanghao-1 bin]# python2 -vpython 2.7.5
步骤15、此时发现安装完成后，无法通过pip3命令安装相关模块，如：
[root@huanghao-1 ~]# pip3 install flaskwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.warning: retrying (retry(total=4, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=3, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=2, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=1, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=0, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/could not fetch url https://pypi.org/simple/flask/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/flask/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingerror: could not find a version that satisfies the requirement flask (from versions: none)error: no matching distribution found for flaskwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: there was an error checking the latest version of pip.[root@node1 python-3.10.9]# pip3 install --upgrade pipwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.requirement already satisfied: pip in /usr/local/python3.10/lib/python3.10/site-packages (22.3.1)warning: retrying (retry(total=4, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=3, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=2, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=1, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=0, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. it is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venvwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: there was an error checking the latest version of pip.
如上出现报错，此时可以按照如下方法进行解决。
[root@huanghao-1 ~]# mkdir -p ~/.pip[root@huanghao-1 ~]# vi ~/.pip/pip.conf
（2）在上一步编辑文件中，新增如下内容：
[global]index-url = http://mirrors.aliyun.com/pypi/simple[install]trusted-host = mirrors.aliyun.com （3）此时再次安装相应模块，如下可以成功了。

步骤1、首先使用 python -v 命令查看一下是否安装python，如下所示：
[root@huanghao-1 ~]# python -vpython 2.7.5
由上面命令可以知道，centos7默认安装了python2.7.5 ，因为一些命令要用它，比如yum 它使用的是python2.7.5。
步骤2、然后使用命令 which python 查看一下python可执行文件的位置，可见执行文件在/usr/bin/ 目录下。如下所示：
[root@huanghao-1 ~]# which python/usr/bin/python
步骤3、通过cd /usr/bin/命令切换到/usr/bin/目录下执行ll python* 命令查看，如下所示 ：

步骤5、通过yum命令先安装相关包：
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel
[root@huanghao-1 bin]# yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel-bash: /usr/bin/yum: /usr/bin/python: bad interpreter: no such file or directory
执行以上命令后，可以报错了，不要慌！！这是因为我们在步骤4中改变了其环境变量，在/usr/bin目录下，通过命令mv python.bak python还原回来即可。再次执行安装命令就正常了。但是安装完后记得备份回去！！！
mv python python.bak 步骤6、下载python3.10.9的源码，自己创建一个目录保存源码，我自己放在/home/目录下。通过cd /home/命令切换到/home/目录下，执行wget下载命令：
wget https://www.python.org/ftp/python/3.10.9/python-3.10.9.tar.xz 如果自己系统没有wget命令，则yum安装一下。
yum install-y wget 自己想安装什么python3版本，就到https://www.python.org/getit/这个网站找，只需将以上版本路径替换即可。
（1）如我这里安装python3.10.9，打开上面网址后如下图所示：

（3）此时复制链接地址后，即可通过wget + 链接地址进行python源码下载，如下命令所示，这里对应步骤6的命令：
wget https://www.python.org/ftp/python/3.10.9/python-3.10.9.tar.xz
步骤7、在/home/目录下已经看到下载好的源码，通过tar -xvjf python-3.7.0a4.tar.xz命令进行解压缩。如下所示：
[root@huanghao-1 home]# lltotal 19156-rw-r--r-- 1 root root 19612112 dec 7 03:01 python-3.10.9.tar.xz[root@huanghao-1 home]# tar -xvjf python-3.10.9.tar.xz
步骤8、/home/目录下，通过命令cd python-3.10.9切换进入源码包目录。
cd python-3.10.9
步骤9、编译安装，依次执行以下命令进行：
./configure prefix=/usr/local/python3.10 --with-sslmake && make install
等待安装完毕后，通过命令cd /usr/local/切换到/usr/local/目录下，通过ll命令查看，就会有python3.10目录了,如下图所示：
[root@huanghao-1 python-3.10.9]# cd /usr/local/[root@huanghao-1 local]# lltotal 0drwxr-xr-x. 2 root root 6 aug 12 2015 bindrwxr-xr-x. 2 root root 6 aug 12 2015 etcdrwxr-xr-x. 2 root root 6 aug 12 2015 gamesdrwxr-xr-x. 2 root root 6 aug 12 2015 includedrwxr-xr-x. 2 root root 6 aug 12 2015 libdrwxr-xr-x. 2 root root 6 aug 12 2015 lib64drwxr-xr-x. 2 root root 6 aug 12 2015 libexecdrwxr-xr-x 6 root root 52 mar 26 19:06 python3.10drwxr-xr-x. 2 root root 6 aug 12 2015 sbindrwxr-xr-x. 5 root root 46 jul 28 2018 sharedrwxr-xr-x. 2 root root 6 aug 12 2015 src[root@huanghao-1 local]#
步骤10、将python3.10版本对应的执行文件添加软链接到执行目录下/usr/bin，通过以下命令完成：
ln -s /usr/local/python3.10/bin/python3.10 /usr/bin/python
最终结果如下所示：
[root@huanghao-1 bin]# cd /usr/bin/[root@huanghao-1 bin]# ll python* lrwxrwxrwx 1 root root 36 mar 26 19:11 python -> /usr/local/python3.10/bin/python3.10lrwxrwxrwx. 1 root root 9 jul 28 2018 python2 -> python2.7-rwxr-xr-x. 1 root root 7136 nov 20 2015 python2.7lrwxrwxrwx. 1 root root 7 jul 28 2018 python.bak -> python2
步骤11、测试是否成功安装，执行python -v命令，执行python2 -v，输出如下所示：成功安装python3.10.9版本。
[root@huanghao-1 bin]# python -vpython 3.10.9[root@huanghao-1 bin]# python2 -vpython 2.7.5
步骤12、因为执行yum等命令需要python2版本，所以我们还要修改yum配置及其它相关配置:
(1)执行命令vi /usr/bin/yum进行修改，修改内容如下：
把#! /usr/bin/python修改为：
#! /usr/bin/python2
（2）执行命令vi /usr/libexec/urlgrabber-ext-down
把文件里面的#! /usr/bin/python 也要修改为：
#! /usr/bin/python2
（3）执行命令vi /usr/sbin/firewalld
文件里面的#!/usr/bin/python -es也要修改为：
#!/usr/bin/python2 -es
步骤13、建立pip3的软链接，执行以下命令：
ln -s /usr/local/python3.10/bin/pip3 /usr/bin/pip3
步骤14、这样python3版本就安装完成，同时python2也存在：可以通过以下命令进行查看：
[root@huanghao-1 bin]# python -vpython 3.10.9[root@huanghao-1 bin]# python2 -vpython 2.7.5
步骤15、此时发现安装完成后，无法通过pip3命令安装相关模块，如：
[root@huanghao-1 ~]# pip3 install flaskwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.warning: retrying (retry(total=4, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=3, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=2, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=1, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/warning: retrying (retry(total=0, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/flask/could not fetch url https://pypi.org/simple/flask/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/flask/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingerror: could not find a version that satisfies the requirement flask (from versions: none)error: no matching distribution found for flaskwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: there was an error checking the latest version of pip.[root@node1 python-3.10.9]# pip3 install --upgrade pipwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.requirement already satisfied: pip in /usr/local/python3.10/lib/python3.10/site-packages (22.3.1)warning: retrying (retry(total=4, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=3, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=2, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=1, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/warning: retrying (retry(total=0, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(can't connect to https url because the ssl module is not available.)': /simple/pip/could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. it is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venvwarning: pip is configured with locations that require tls/ssl, however the ssl module in python is not available.could not fetch url https://pypi.org/simple/pip/: there was a problem confirming the ssl certificate: httpsconnectionpool(host='pypi.org', port=443): max retries exceeded with url: /simple/pip/ (caused by sslerror(can't connect to https url because the ssl module is not available.)) - skippingwarning: there was an error checking the latest version of pip.
如上出现报错，此时可以按照如下方法进行解决。
[root@huanghao-1 ~]# mkdir -p ~/.pip[root@huanghao-1 ~]# vi ~/.pip/pip.conf
（2）在上一步编辑文件中，新增如下内容：
[global]index-url = http://mirrors.aliyun.com/pypi/simple[install]trusted-host = mirrors.aliyun.com （3）此时再次安装相应模块，如下可以成功了。

pip3 install --upgrade pip （5）下面可以通过创建一段脚本，验证下载的模块是否可以正常使用，创建名为hello_flask.py的文件，内容如下：
[root@huanghao-1 ~]# cat hello_flask.py from flask import flaskapp = flask(__name__)@app.route('/')def hello(): return 'hello flask'if __name__ == '__main__': app.run(host='0.0.0.0',port=8888,debug=true)
（6）执行hello_flask.py脚本
python hello_flask.py
（7）当前我的服务器地址是192.168.20.232，在浏览器访问如下地址：得到响应如下图所示：
到此整个安装部署完成，大家可以参考以上步骤自己进行各个python3版本的安装，注意更改到自己实际环境中的对应目录即可。
