打算爬蟲,安裝mysqldb 結果使用pip安裝出錯
在centos-6.4上pip install mysql-python，報錯如下[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):

工作環境：centos6.4
解決方法：1. 通過報錯資訊看出是缺少mysql_config，在/usr/bin/下面應該有的mysql_config檔案沒有，網上的解決方案都是apt-get install libmysqlclient-dev，但是apt-get是debian、ubuntu系列的網路安裝命令，yum是redhat、centos、fedora是網路安裝命令，接著發現centos上應該安裝mysql-devel
2. yum install mysql-devel，發現有衝突，報錯如下：
--> 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檢視mysql的安裝情況
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移除已有的安裝包
5. 再次使用yum install mysql-devel 發現和mysql-server， mysql-client的版本有衝突
7. 安裝成功後，去/usr/bin/目錄下，發現生成了mysql_config檔案，繼續pip install mysql-python，順利完成。
