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

----------------------------------------
工作環境：centOS6.4
解決方法：1. 通過報錯信息看出是缺少mysql_config，在/usr/bin/下面應該有的mysql_config文件沒有，網上的解決方案都是apt-get install libmysqlclient-dev，但是apt-get是Debian、Ubuntu系列的網絡安裝命令，yum是Redhat、Centos、Fedora是網絡安裝命令，接着發現Centos上應該安裝mysql-devel
2. yum install mysql-devel，發現有沖突，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查看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的版本有沖突
6. 去網上尋找相同的版本下載http://downloads.skysql.com/archive/index/p/mysql/v/5.5.16，下載64bit的rpm文件，使用rpm -ivh MySQL-devel-5.5.16-1.linux2.6.x86_64.rpm安裝
7. 安裝成功后，去/usr/bin/目錄下，發現生成了mysql_config文件，繼續pip install mysql-python，順利完成。
