【摘要】特别提示:在安装前,最好不要东系统自带的python2.6的版本,因为系统中有些软件是需要依赖python2.6的。比如yum就需要依赖python2.6 前置依赖包: [root@root ~]# yum install zlib-devel [root@root ~]# yum install openssl-devel [root@root ~]# yum install gcc ...

特别提示:在安装前,最好不要东系统自带的python2.6的版本,因为系统中有些软件是需要依赖python2.6的。比如yum就需要依赖python2.6

前置依赖包:
[root@root ~]# yum install zlib-devel [root@root ~]# yum install openssl-devel [root@root ~]# yum install gcc [root@root ~]# yum install -y libffi-devel
一、安装python3.6
1、下载python3.6
[root@root ~]# wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
2、解压
[root@root ~]# tar -xzvf Python-3.6.0.tgz
建个编译目录:
[root@root ~]# mkdir /usr/local/python3
然后编译、安装:
[root@root ~]# cd Python-3.6.0 [root@root ~]# ./configure --prefix=/usr/local/python3 [root@root ~]# make && make install
3、建立软链接:
[root@root ~]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
4、查看刚才安装python3.6版本:
[root@root ~]# python3 -V Python 3.6.0
二、安装pip
1、安装pip前需要前置安装setuptools
[root@root ~]# wget --no-check-certificate https://files.pythonhosted.org/packages/ef/1d/201c13e353956a1c840f5d0fbf0461bd45bbd678ea4843ebf25924e8984c/setuptools-40.2.0.zip [root@root ~]# unzip setuptools-40.2.0.zip [root@root ~]# cd setuptools-40.2.0 [root@root setuptools-40.2.0]# python3 setup.py build [root@root setuptools-40.2.0]# python3 setup.py install
2、安装pip
[root@root ~]# wget https://pypi.python.org/packages/source/p/pip/pip-9.0.1.tar.gz [root@root ~]# tar -zxvf pip-9.0.1.tar.gz [root@root ~]# cd pip-9.0.1 [root@root pip-9.0.1]# python3 setup.py build [root@root pip-9.0.1]# python3 setup.py install
3、建立软链接
[root@root ~]# ln -s /usr/local/python3/bin/pip /usr/bin/pip
至此python3.6及pip9.0安装完成
二、测试使用pip elasticsearch5
[root@root ~]# pip install elasticsearch5 Collecting elasticsearch5 Downloading https://files.pythonhosted.org/packages/de/99/9cfd6881a4242a5d03c5c817b0f3231ba3afe5248118e2be465c29c51dce/elasticsearch5-5.5.6-py2.py3-none-any.whl (62kB) 100% || 71kB 41kB/s Collecting urllib3>=1.21.1 (from elasticsearch5) Downloading https://files.pythonhosted.org/packages/e0/da/55f51ea951e1b7c63a579c09dd7db825bb730ec1fe9c0180fc77bfb31448/urllib3-1.25.6-py2.py3-none-any.whl (125kB) 100% || 133kB 10kB/s Installing collected packages: urllib3, elasticsearch5 Successfully installed elasticsearch5-5.5.6 urllib3-1.25.6 You are using pip version 9.0.1, however version 19.3.1 is available.

上面这个提示信息是pip的版本为9.0.1的,但提示我们19.3.1的版本是可用的,我们可以通过pip install --upgrade pip 来升级
[root@root ~]# pip install --upgrade pip Collecting pip Downloading https://files.pythonhosted.org/packages/00/b6/9cfa56b4081ad13874b0c6f96af8ce16cfbc1cb06bedf8e9164ce5551ec1/pip-19.3.1-py2.py3-none-any.whl (1.4MB) 100% || 1.4MB 967kB/s Installing collected packages: pip Found existing installation: pip 9.0.1 Uninstalling pip-9.0.1: Successfully uninstalled pip-9.0.1 Successfully installed pip-19.3.1
