我們原裝的centos上是有python2.7的,不建議刪除,可以做個python3共存的。
# pythonpython 2.7.5 (default, nov 20 2015, 02:00:19)
[gcc 4.8.5 20150623 (red hat 4.8.5-4)] on linux2
>>>
# which python/usr/bin/python
可以檢視位置,一般是位於/usr/bin/python目錄下。
首先安裝依賴包,這個比較多,我這裡寫的的比較全,要是有時候make或者make install 出現問題,大部分都是依賴包缺失或者損壞,需要一次性安好。
# yum -y groupinstall "development tools"# 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
# yum -y install gcc gcc-c++ zlib zlib-devel libffi-devel
# wget# tar -xvf python-3.7.0b3.tgz
# cd python-3.7.0b3/
# ./configure --prefix=/data/soft/python/
# make && make install
# ln -s /data/soft/python/bin/python3 /data/soft/python3# ln -s /data/soft/python/bin/pip3 /data/soft/pip3
# vim /etc/profile加入下面兩行
path=/data/soft/python/bin:/data/soft/python/lib:$path
export path
# source /etc/profile
# python3python 3.7.0b3 (default, may 2 2018, 13:55:41)

大功告成,寫完收工!!!
