mysqldbcopy 克隆整个库
例:mysqldbcopy –source=root:'123456'@localhost:3306:/tmp/mysql.sock –destination=root:'123456'@localhost:3306:/tmp/mysql.sock db:db_clone
mysqldiskusage 统计表空间、各种日志文件占用的体积
例:mysqldiskusage –server=root:'123456'@localhost:3306:/tmp/mysql.sock –all -v
mysqlfrm 在故障的时候根据frm提取某个表结构 (不包括外键约束、自增长序列编号)
例: mysqlfrm –basedir=/usr/local/mysql /data/hellodb/classes.frm –port=3310 –user=root # 注意这个端口是随便起的
mysqlindexcheck 找出某个库下的冗余索引
例:mysqlindexcheck –server=root:'123456'@localhost:3306:/tmp/mysql.sock grafana -f vertical -r -d –stats
mysqlprocgrep 找出符合某些条件的用户连接
参数:
-G, –basic-regexp, –regexp
use 'REGEXP' operator to match pattern. Default is to
use 'LIKE'.
-Q, –print-sql, –sql
print the statement instead of sending it to the

–kill-query kill query for all matching processes.
–print print all matching processes.
-f FORMAT, –format=FORMAT

-v, –verbose control how much information is displayed. e.g., -v =
verbose, -vv = more verbose, -vvv = debug
–match-id=PATTERN match the 'ID' column of the PROCESSLIST table.
–match-user=PATTERN match the 'USER' column of the PROCESSLIST table.
–match-host=PATTERN match the 'HOST' column of the PROCESSLIST table.
–match-db=PATTERN match the 'DB' column of the PROCESSLIST table.

state more than a given time.
例:# kill掉sleep状态,且处于sleep超过90秒的用户连接:
mysqlprocgrep –server=root:'123456'@localhost:3306:/tmp/mysql.sock -f vertical –match-command='Sleep' –age=90s –kill-connection
mysqlrpladmin
关于这个工具,可以参考兰春大神的博文 https://yq.aliyun.com/articles/59234#
mysqlserverinfo 列出数据库的明细情况(-d 显示各个default值, –format=vertical 列式显示)
例:mysqlserverinfo –server=root:'123456'@localhost:3306:/tmp/mysql.sock -d –format=vertical
