【轉】MySQL-Utilities，mysql工具包

原文：https://blog.csdn.net/leshami/article/details/52795777 

MySQL Utilities 是一組基於python語言編寫的python庫的命令行實用工具集,依賴於python 2.6。該工具提供了MySQL數據庫運維工程中經常使用的一些工具，諸如克隆、複製、比較、差別、導出、導入、安裝、配置、索引、磁盤查看等等。有了這個工具包，就比如那些個神醫大夫，無論大病小病，先去搞個化驗，搞個CT，你也能夠當華佗。MySQL Utilities提供了各類平臺的軟件包，若是沒有找到對應本身平臺的包，能夠經過源碼進行編譯安裝。本文主要描述MySQL Utilities安裝以及各個工做功能初步描述。

2、安裝需求及下載地址

需求
　　Python 2.6
　　MySQL Connector/Python 鏈接器
下載地址：
　　http://dev.mysql.com/downloads/utilities/

3、安裝示例

###本次安裝使用1.6.4版本，安裝前，須要先安裝mysql到python鏈接器
# cat /etc/redhat-release 
CentOS release 6.7 (Final)
# rpm -Uvh mysql-connector-python-2.1.4-1.el6.x86_64.rpm 
# rpm -Uvh mysql-utilities-1.6.4-1.el6.noarch.rpm

###若是沒有安裝鏈接器，則收到以下錯誤提示
# rpm -Uvh mysql-utilities-1.6.4-1.el6.noarch.rpm 
warning: mysql-utilities-1.6.4-1.el6.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
mysql-connector-python >= 2.0.0 is needed by mysql-utilities-1.6.4-1.el6.noarch

###查看安裝後生成的文件 
# rpm -ql mysql-utilities-1.6.4-1.el6|grep "/usr/bin"
