MySQL Utilities 是一组基于python语言编写的python库的命令行实用工具集,依赖于python 2.6。该工具提供了MySQL数据库运维工程中常用的一些工具,诸如克隆、复制、比较、差异、导出、导入、安装、配置、索引、磁盘查看等等。有了这个工具包,就好比那些个神医大夫,不管大病小病,先去搞个化验,搞个CT,你也可以当华佗。MySQL Utilities提供了各种平台的软件包,如果没有找到对应自己平台的包,可以通过源码进行编译安装。本文主要描述MySQL Utilities安装以及各个工作功能初步描述。

二、安装需求及下载地址

下载官网:https://downloads.mysql.com/archives/utilities/

需求

Python 2.6

MySQL Connector/Python 连接器

下载地址:

http://dev.mysql.com/downloads/utilities/

三、安装示例

###本次安装使用1.6.4版本,安装前,需要先安装mysql到python连接器

#cat /etc/redhat-release

CentOS release6.7(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

###如果没有安装连接器,则收到如下错误提示

# 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

###查看安装后生成的文件

# rpm-ql mysql-utilities-1.6.4-1.el6|grep "/usr/bin"

/usr/bin/mysqlauditadmin/usr/bin/mysqlauditgrep/usr/bin/mysqlbinlogmove/usr/bin/mysqlbinlogpurge/usr/bin/mysqlbinlogrotate/usr/bin/mysqldbcompare/usr/bin/mysqldbcopy/usr/bin/mysqldbexport/usr/bin/mysqldbimport/usr/bin/mysqldiff/usr/bin/mysqldiskusage/usr/bin/mysqlfailover/usr/bin/mysqlfrm/usr/bin/mysqlgrants/usr/bin/mysqlindexcheck/usr/bin/mysqlmetagrep/usr/bin/mysqlprocgrep/usr/bin/mysqlreplicate/usr/bin/mysqlrpladmin/usr/bin/mysqlrplcheck/usr/bin/mysqlrplms/usr/bin/mysqlrplshow/usr/bin/mysqlrplsync/usr/bin/mysqlserverclone/usr/bin/mysqlserverinfo/usr/bin/mysqlslavetrx/usr/bin/mysqluc/usr/bin/mysqluserclone
