centos下保留python2安裝python3

1. 安裝依賴環境

#

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

#

wget

3. 建立python3的目錄

#

mkdir /usr/local/python3

#

tar -zxvf python-3.a.b.tgz
#cd python-3.a.b

5. 執行

#

./configure --prefix=/usr/local/python3
#make && make install

6. 建立python3的軟鏈結

#

ln -s /usr/local/python3/bin/python3 /usr/bin/python3

7. 建立pip3的軟鏈結

#

ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

8. 測試命令 python3 和 pip3

#

python3
#pip3
