个人备注网页, 不喜勿扰
安装此部分功能时需要注意文件夹位置!!!!!
1.最小化安装的centos 有很多编译环境没有 需要安装
为了省事 可以全部安装
[root@base ~]# yum groupinstall -y "Development tools"
出现 :警告：分组 development 不包含任何可安装软件包。
执行 yum clean all 再执行上边的命令
[root@base ~]# yum install -y openssl-devel
[root@base ~]# yum install -y zlib
[root@base ~]# yum install -y zlib-devel
2.需要安装Python3.5
[root@base ~]# tar -zxf downloads/Python-3.5.3.tgz
[root@base ~]# cd Python-3.5.3/
[root@base Python-3.5.3]#./configure --prefix=/root/python3
[root@base Python-3.5.3]# make
[root@base Python-3.5.3]# make test
[root@base Python-3.5.3]# make install
[root@base Python-3.5.3]# cd /usr/bin
删除原有软连接
[root@base bin]# rm -rf python
[root@base bin]# ln -s /root/python3/bin/python3 ./python
[root@base bin]# ln -s /root/python3/bin/python3 ./python3
[root@base bin]# ln -s /root/python3/bin/pip3 ./pip3
3.验证是否成功
[root@base bin]# python
Python 3.5.3 (default, Aug 10 2017, 15:01:00)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
[root@base bin]# python3
Python 3.5.3 (default, Aug 10 2017, 15:01:00)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
[root@base bin]# pip3 list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
pip (9.0.1)
setuptools (28.8.0)
4.yum 中需要修改部分头文件
[root@base bin]# vi yum
将第一行
!/usr/bin/python
修改为
