0.1 查看系统版本
1 [root@localhost ~]# uname -a 2 Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
1.安装requests
1.1 软件下载
1 [root@localhost ~]# wget \ 2 https://pypi.python.org/packages/b0/e1/eab4fc3752e3d240468a8c0b284607899d2fbfb236a56b7377a329aa8d09/requests-2.18.4.tar.gz#md5=081412b2ef79bdc48229891af13f4d82
1.2 解压
1 [root@localhost ~]# tar xf requests-2.18.4.tar.gz
1.3安装requests
1 [root@localhost ~]# cd requests-2.18.4 2 [root@localhost requests-2.18.4]# python setup.py install
1.4 安装报错
1 [root@1e supervisor-3.0]# python setup.py install 2 Traceback (most recent call last): 3 File "setup.py", line 31, in <module> 4 from setuptools import setup, find_packages 5 ImportError: No module named setuptools
原因是没有找到setuptools包，再次安装这个包
下载setuptools :
1 [root@localhost requests-2.18.4]#wget \ 2 https://pypi.python.org/packages/a4/c8/9a7a47f683d54d83f648d37c3e180317f80dc126a304c45dc6663246233a/setuptools-36.5.0.zip#md5=704f500dd55f4bd0be905444f3ba892c
利用unzip进行解压
1 [root@localhost requests-2.18.4]# unzip setuptools-36.5.0.zip
如果提示没有找到unzip命令，则利用yum安装即可
1 [root@localhost requests-2.18.4]# yum install zip unzip
解压完成后即可进行安装
1 [root@localhost requests-2.18.4]# cd setuptools-36.5.0 2 [root@localhost setuptools-36.5.0]# python setup.py install
安装完成后即可进行安装requests
1 [root@localhost setuptools-36.5.0]# cd ../ 2 [root@localhost requests-2.18.4]# python setup.py install
安装完成检验，进入python交互式界面进行导入包即可
1 [root@localhost requests-2.18.4]# python 2 Python 2.7.5 (default, Nov 6 2016, 00:28:07) 3 [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2 4 Type "help", "copyright", "credits" or "license" for more information. 5 >>> import requests 6 >>>
2.安装requests
2.1 软件下载
1 [root@localhost ~]# wget \ 2 https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c
2.2 解压并且安装
1 [root@localhost ~]# unzip MySQL-python-1.2.5.zip 2 [root@localhost ~]# cd MySQL-python-1.2.5 3 [root@localhost MySQL-python-1.2.5]# python setup.py install
2.3 安装报错
1 sh: mysql_config: not found 2 Traceback (most recent call last): 3 File "setup.py", line 15, in <module> 4 metadata, options = get_config() 5 File "/home/zhxia/apps/source/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config 6 libs = mysql_config("libs_r") 7 File "/home/zhxia/apps/source/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config 8 raise EnvironmentError("%s not found" % (mysql_config.path,)) 9 EnvironmentError: mysql_config not found
安装libmysqlclient-dev
1 [root@localhost MySQL-python-1.2.5]# yum install libmysqlclient-dev
安装报错，并没有发现libmysqlclient-dev包
1 [root@localhost requests-2.18.4]# yum install libmysqlclient-dev 2 Loaded plugins: fastestmirror 3 Loading mirror speeds from cached hostfile 4 * base: mirrors.sohu.com 5 * extras: mirrors.sohu.com 6 * updates: mirrors.sohu.com 7 No package libmysqlclient-dev available. 8 Error: Nothing to do 9 [root@localhost requests-2.18.4]#
之所以会出现如下原因是系统没有找到mysql的依赖包,那么我们可以自己安装依赖，这儿依赖可以为mysql 也可以为mariadb
1 [root@localhost MySQL-python-1.2.5]# yum list all | grep mariadb | grep dev 2 mariadb-devel.x86_64 1:5.5.56-2.el7 @base 3 mariadb-embedded-devel.x86_64 1:5.5.56-2.el7 @base 4 mariadb-devel.i686 1:5.5.56-2.el7 base 5 mariadb-embedded-devel.i686 1:5.5.56-2.el7 base 6 [root@localhost MySQL-python-1.2.5]#
安装mariadb的dev包
1 [root@localhost MySQL-python-1.2.5]# yum install mariadb-devel mariadb-embedded-devel
再次安装MySQL-python-1.2.5
[root@localhost MySQL-python-1.2.5]# python setup.py install
再次报错

再次安装python-devel
1 [root@localhost MySQL-python-1.2.5]# yum install python-devel
再次尝试
1 [root@localhost MySQL-python-1.2.5]# python setup.py install
检测是否安装OK
1 [root@localhost MySQL-python-1.2.5]# python 2 Python 2.7.5 (default, Aug 4 2017, 00:39:18) 3 [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2 4 Type "help", "copyright", "credits" or "license" for more information. 5 >>> import MySQLdb 6 /usr/lib64/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/lib64/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg/_mysql.pyc, but /root/python-script/MySQL-python-1.2.5 is being added to sys.path 7 >>>
