打算爬虫,安装mysqldb 结果使用pip安装出错
在centos-6.4上pip install mysql-python，报错如下[sentry@kjtest111 mysql-python]$ pip install mysql-python

----------------------------------------
工作环境：centOS6.4
解决方法：1. 通过报错信息看出是缺少mysql_config，在/usr/bin/下面应该有的mysql_config文件没有，网上的解决方案都是apt-get install libmysqlclient-dev，但是apt-get是Debian、Ubuntu系列的网络安装命令，yum是Redhat、Centos、Fedora是网络安装命令，接着发现Centos上应该安装mysql-devel
2. yum install mysql-devel，发现有冲突，报错如下：
--> Running transaction check
---> Package mysql-devel.x86_64 0:5.1.69-1.el6_4 will be installed
--> Processing Dependency: mysql = 5.1.69-1.el6_4 for package: mysql-devel-5.1.69-1.el6_4.x86_64
--> Running transaction check
---> Package mysql.x86_64 0:5.1.69-1.el6_4 will be installed

--> Processing Conflict: mysql-5.1.69-1.el6_4.x86_64 conflicts MySQL
--> Finished Dependency Resolution
Error: mysql conflicts with MySQL-devel-5.5.30-1.el6.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
3. 使用 rpm -qa|grep mysql查看mysql的安装情况
mysql-devel-5.5.16-1.el6_4.x86_64
mysql-client-5.5.16-1.el6_4.x86_64
mysql-server-5.5.16-1.el6_4.x86_64
4. 使用rpm -e mysql-devel-5.5.16-1.el6_4.x86_64移除已有的安装包
5. 再次使用yum install mysql-devel 发现和mysql-server， mysql-client的版本有冲突
6. 去网上寻找相同的版本下载http://downloads.skysql.com/archive/index/p/mysql/v/5.5.16，下载64bit的rpm文件，使用rpm -ivh MySQL-devel-5.5.16-1.linux2.6.x86_64.rpm安装
7. 安装成功后，去/usr/bin/目录下，发现生成了mysql_config文件，继续pip install mysql-python，顺利完成。
