一个不错的MySQL集群管理工具

官方网站：http://www.maatkit.org/
安装很简单,比如我下载的maatkit-2725.zip ,释放后整个文件夹传到服务器上,对于软件环境要求,一般就是DBD::mysql和DBI,当然少不了perl.安装只要几个命令:
# cd maatkit-2725/
# perl Makefile.PL
# make
# make install

就可以使用了,下面是一些有用的功能
1、mk-table-checksum 检查主从表是否一致及有效的工具
2、mk-table-sync 使表一致的工具，不必重载从表而能够保证一致
3、mk-visual-explain exlpain解释工具
4、mk-heartbeat 主从同步的监视工具，能够给出从落后于主多少
5、mk-parallel-dump 多线程的mysqldump工具
6、mk-parallel-restore 多线程的表修复工具
7、mk-query-profiler 查询检测分析工具
8、mk-deadlock-logger 死锁的记录工具
9、mk-duplicate-key-checker key侦测工具
10、mk-show-grants 权限管理显示工具
11、mk-slave-restart slave的检测和重启工具
12、mk-slave-delay slave delay replication 的工具
mk-archiver Archive rows from a MySQL table into another table or a file.
mk-audit Analyze, summarize and report on MySQL config, schema and operation
mk-checksum-filter Filter checksums from mk-table-checksum.
mk-deadlock-logger Extract and log MySQL deadlock information.
mk-duplicate-key-checker Find possible duplicate indexes and foreign keys on MySQL tables.
