一鍵腳本
yum groupinstall 'Development Tools' zlib-devel bzip2-devel gcc openssl-devel ncurses-devel readline-devel -y \ && wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz \ && tar -zxf Python* \ && cd Python-3.6.5 \ && ./configure --prefix=/usr/local/python3 \ && make && make install \ && echo 'export PATH=$PATH:/usr/local/python3/bin' >> ~/.bashrc \ && rm -f /usr/bin/python \ && ln -s /usr/local/python3/bin/python3.6 /usr/bin/python \ && ln -s /usr/local/python3/bin/pip3 /usr/bin/pip \ && mkdir /root/.pip/ \ && cat >/root/.pip/pip.conf<<EOF [global] index-url =https://pypi.tuna.tsinghua.edu.cn/simple EOF
1、安裝開發包和依賴包
yum groupinstall 'Development Tools' -y #安裝開發包
yum install zlib-devel bzip2-devel gcc openssl-devel ncurses-devel -y #安裝可能依賴的包
yum install readline-devel -y #不安裝進入python解釋器的時候可能輸入字符會亂碼
2、下載 Python3.6代碼包
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
3 編譯
[root@db02 ~]# tar -zxf Python-3.6.5.tgz
[root@db02 ~]# cd Python-3.6.5
[root@db02 Python-3.6.5]#
./configure --prefix=/usr/local/python3
make && make install
4 設置環境變量
echo 'export PATH=$PATH:/usr/local/python3/bin' >> ~/.bashrc 做一些必要配置 rm -f /usr/bin/python #刪除老版本的軟鏈接 ln -s /usr/local/python3/bin/python3.6 /usr/bin/python #做新版本的軟鏈接 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip #pip軟鏈接 mkdir /root/.pip/ #國內鏡像 vi /root/.pip/pip.conf cat >/root/.pip/pip.conf<<EOF [global] index-url =https://pypi.tuna.tsinghua.edu.cn/simple EOF
安裝mycli
pip install mycli ln -s /usr/local/python3/bin/mycli /usr/bin/mycli
5、更新python2.6的yum配置。
vim /usr/bin/yum
通過vim修改yum的配置
#!/usr/bin/python改為#!/usr/bin/python2.6，保存退出。
完成了python3的安裝。
