MySQL缺失mysql_config文件

问题：

工作中需要布置django-sentry日志服务器，在centos-6.4上pip install mysql-python，报错如下

[sentry@kjtest111 mysql-python]$ pip install mysql-python
Downloading/unpacking mysql-python
  Running setup.py egg_info for package mysql-python
    sh: /usr/bin/mysql_config: No such file or directory
    Traceback (most recent call last):
      File "<string>", line 16, in <module>
      File "/tmp/pip-build-sentry/mysql-python/setup.py", line 18, in <module>
        metadata, options = get_config()
      File "setup_posix.py", line 43, in get_config
        libs = mysql_config("libs_r")
      File "setup_posix.py", line 25, in mysql_config
        raise EnvironmentError("%s not found" % (mysql_config.path,))
    EnvironmentError: /usr/bin/mysql_config not found
    Complete output from command python setup.py egg_info:

  File "setup_posix.py", line 25, in mysql_config
    raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
----------------------------------------

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-client-5.5.30-1.el6.x86_64 conflicts mysql
--> Processing Conflict: MySQL-server-5.5.30-1.el6.x86_64 conflicts mysql
--> 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。
