CentOS大数据实验环境更改记录
标签(空格分隔): 未分类
1.修改163的yum源
使用说明
首先备份/etc/yum.repos.d/CentOS-Base.repo
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)
CentOS6
运行以下命令生成缓存
yum clean allyum makecache
2.更新python从2.6.6版本为2.7
#wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2#tar jxvf Python-2.7.5.tar.bz2#cd Python-2.7.5#./configure --prefix=/usr/local #make && make altinstall #mv /usr/bin/python /usr/bin/python2.6.6#ln -s /usr/local/bin/python2.7 /usr/bin/python
3.安装pip
1)安装setuptools解压安装遇到错误RuntimeError: Compression requires the (missing) zlib moduleyum install zlib& zilib devel
然后遇到yum因为python版本不对错误错误:
[root@localhost bin]# yum install pipThere was a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was: No module named yumPlease install a package which provides this module, orverify that the module is installed correctly.It's possible that the above module doesn't match thecurrent version of Python, which is:2.7.3 (default, Jan 16 2016, 05:59:11) [GCC 4.4.6 20120305 (Red Hat 4.4.6-4)]If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
查找yum文件,并编辑此py文件
[root@develop local]# which yum/usr/bin/yum[root@develop local]# vi /usr/bin/yum将#!/usr/bin/python改为:#!/usr/bin/python2.6然后保存OK.补充:yum基于python写的。
4.安装zlib&zlib-devel
重新编译python/.configure
make
make install
然后重新安装setuptools 5.遇到wangqi is not in the sudoers file.
#visudo## Allow root to run any commands anywhereroot ALL=(ALL) ALLwangqi ALL=(ALL) ALL
6.遇到ImportError: cannot import name HTTPSHandler
yum install openssl openssl-devel -y
之后,再重新安装Python即可。/.configure
make
make install
7.pip安装完成
8.安装numpy,9.安装pandas出现问题:UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128)解决方法:修改mimetypes.py文件,路径位于python的安装路径下的Lib\mimetypes.py文件。在import下添加如下几行:if sys.getdefaultencoding() != 'gbk': reload(sys) sys.setdefaultencoding('gbk')
依然报错:
gcc: error trying to exec 'cc1plus': execvp: No such file or directoryerror: command 'gcc' failed with exit status 1
尝试解决:
yum -y install gcc
依然报错:
Command /usr/local/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/pandas/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-5RbGXm-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/pandasTraceback (most recent call last): File "/usr/local/bin/pip", line 9, inload_entry_point('pip==1.5.6', 'console_scripts', 'pip')() File "/usr/local/lib/python2.7/site-packages/pip-1.5.6-py2.7.egg/pip/__init__.py", line 185, in main return command.main(cmd_args) File "/usr/local/lib/python2.7/site-packages/pip-1.5.6-py2.7.egg/pip/basecommand.py", line 161, in main text = '\n'.join(complete_log)UnicodeDecodeError: 'gbk' codec can't decode bytes in position 97-98: illegal multibyte sequence
使用安装包直接进行安装,发现是以下问题:
gcc: error trying to exec 'cc1plus': execvp: No such file or directoryerror: command 'gcc' failed with exit status 1
安装gcc-c++
[root@localhost pandas-0.17.1]# yum list gcc-c++Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfileAvailable Packagesgcc-c++.i686 4.4.7-16.el6 base[root@localhost pandas-0.17.1]# yum -y install gcc-c++.i686
遇到问题
No local packages or download links found for python-dateutilerror: Could not find suitable distribution for Requirement.parse('python-dateutil')
pip install python-dateutil
终于大功告成
