一. 安装依赖的库
yum -y install python-devel openssl openssl-devel gcc sqlite sqlite-devel mysql-devel libxml2-devel libxslt-devel
二. 安装Python
下载python 2.7.13
[root@server2 ~]# mkdir /software [root@server2 ~]# cd /software/ [root@server2 software]# wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz [root@server2 software]# ll 总用量 36852 -rw-r--r-- 1 root root 17076672 12月 18 04:21 Python-2.7.13.tgz -rw-r--r-- 1 root root 20656090 1月 17 16:07 Python-3.5.3.tgz
解压文件
[root@server2 software]# tar -zxf Python-2.7.13.tgz
进入目录
[root@server2 software]# cd Python-2.7.13
编译安装
[root@server2 Python-2.7.13]# ./configure --prefix=/usr/local/python2.7 --with-threads --enable-shared [root@server2 Python-2.7.13]# make && make altinstall
备份旧python相关命令
===> 有些版本/usr/bin/目录下不存在pip 忽略下面第一行命令即可
[root@server2 Python-2.7.13]# mv /usr/bin/pip /usr/bin/pip_old [root@server2 Python-2.7.13]# mv /usr/bin/easy_install /usr/bin/easy_install_old [root@server2 Python-2.7.13]# mv /usr/bin/python /usr/bin/python_old
新版本python命令做软连接，快捷使用
[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib64 [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib64
测试python是否可以正常使用
[root@server2 ~]# python Python 2.7.13 (default, Apr 11 2017, 11:14:36) [GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
三. 安装pip
下载最新版的pip，然后安装
[root@server2 Python-2.7.13]# cd /software/ [root@server2 software]# wget https://bootstrap.pypa.io/get-pip.py [root@server2 software]# python get-pip.py
查找pip的位置
[root@server2 software]# find / -name pip /usr/local/python2.7/bin/pip
找到pip2.7的路径，为其创建软链作为系统默认的启动版本
[root@server2 software]# ln -s /usr/local/python2.7/bin/pip /usr/bin/pip
测试pip是否可用
[root@server2 software]# pip install Pillow Collecting Pillow Downloading Pillow-4.1.0-cp27-cp27m-manylinux1_x86_64.whl (5.7MB) 100% |████████████████████████████████| 5.7MB 129kB/s Collecting olefile (from Pillow) Downloading olefile-0.44.zip (74kB) 100% |████████████████████████████████| 81kB 541kB/s Building wheels for collected packages: olefile Running setup.py bdist_wheel for olefile ... done Stored in directory: /root/.cache/pip/wheels/20/58/49/cc7bd00345397059149a10b0259ef38b867935ea2ecff99a9b Successfully built olefile Installing collected packages: olefile, Pillow Successfully installed Pillow-4.1.0 olefile-0.44
yum 安装工具只支持系统自带的python版本， 修改配置文件使其可正常使用
查看原版本python
[root@server2 software]# ll /usr/bin/python* lrwxrwxrwx 1 root root 34 4月 11 11:20 /usr/bin/python -> /usr/local/python2.7/bin/python2.7 lrwxrwxrwx 1 root root 6 2月 15 14:33 /usr/bin/python2 -> python -rwxr-xr-x 2 root root 9032 8月 18 2016 /usr/bin/python2.6 ==> 这个就是系统自带的python -rwxr-xr-x 1 root root 1418 8月 18 2016 /usr/bin/python2.6-config lrwxrwxrwx 1 root root 16 4月 11 10:47 /usr/bin/python-config -> python2.6-config -rwxr-xr-x 2 root root 9032 8月 18 2016 /usr/bin/python_old
修改配置文件 /usr/bin/yum
#!/usr/bin/python ===> 修改为 #!/usr/bin/python2.6
测试yum是否可用
[root@server2 software]# yum -y install python-devel 已加载插件：fastestmirror, security 设置安装进程 Loading mirror speeds from cached hostfile * epel: mirrors.aliyun.com 包 python-devel-2.6.6-66.el6_8.x86_64 已安装并且是最新版本 无须任何处理
好了，大功告成!
