阿里雲Centos7.3實踐：安裝Python3.7.2

*非必要執行代碼

yum -y install Development Libraries Development Tools

 安裝Python3相關依賴包

yum -y install zlib zlib-devel;

yum -y install bzip2 bzip2-devel;

yum -y install ncurses ncurses-devel;

yum -y install readline readline-devel;

yum -y install openssl openssl-devel;

yum -y install openssl-static;

yum -y install xz lzma xz-devel;

yum -y install sqlite sqlite-devel;

yum -y install gdbm gdbm-devel;

yum -y install tk tk-devel;

yum -y install libffi libffi-devel;

yum -y install libpcap libpcap-devel;

yum -y install db4 db4-devel;

下載Python3.7.2安裝包

 wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz

解壓，編譯，安裝

tar -zxvf Python-3.7.2.tgz;
cd Python-3.7.2;
./configure;
make && make install;

配置選項 ./configure --enable-optimizations 用於提高Python安裝後的性能

***************************************************************************************************************

配置yum

若更改了python軟鏈接，導致yum不能正常使用，需要編輯yum的配置文件：

vim /usr/bin/yum

同時修改

vim /usr/libexec/urlgrabber-ext-down

將  #!/usr/bin/python 修改爲 #!/usr/bin/python2.7
