SHOW PROCESSLIST显示哪些线程正在运行。您也可以使用mysqladmin processlist语句得到此信息。如果您有SUPER权限,您可以看到所有线程。否则,您只能看到您自己的线程(也就是,与您正在使用的MySQL账户相关的线程)。请参见13.5.5.3节,“KILL语法”。如果您不使用FULL关键词,则只显示每个查询的前100个字符。
本语句报告TCP/IP连接的主机名称(采用host_name:client_port格式),以方便地判定哪个客户端正在做什么。
如果您得到“too many connections”错误信息,并且想要了解正在发生的情况,本语句是非常有用的。MySQL保留一个额外的连接,让拥有SUPER权限的 账户使用,以确保管理员能够随时连接和检查系统(假设您没有把此权限给予所有的用户)。

这个命令中最关键的就是state列,mysql列出的状态主要有以下几种:
Checking table
正在检查数据表(这是自动的)。
Closing tables
正在将表中修改的数据刷新到磁盘中,同时正在关闭已经用完的表。这是一个很快的操作,如果不是这样的话,就应该确认磁盘空间是否已经满了或者磁盘是否正处于重负中。
Connect Out
复制从服务器正在连接主服务器。
Copying to tmp table on disk
由于临时结果集大于tmp_table_size,正在将临时表从内存存储转为磁盘存储以此节省内存。
Creating tmp table
正在创建临时表以存放部分查询结果。
deleting from main table
服务器正在执行多表删除中的第一部分,刚删除第一个表。
deleting from reference tables
服务器正在执行多表删除中的第二部分,正在删除其他表的记录。
Flushing tables
正在执行FLUSH TABLES,等待其他线程关闭数据表。
Killed
发送了一个kill请求给某线程,那么这个线程将会检查kill标志位,同时会放弃下一个kill请求。MySQL会在每次的主循环中检查kill标志位,不过有些情况下该线程可能会过一小段才能死掉。如果该线程程被其他线程锁住了,那么kill请求会在锁释放时马上生效。
Locked
被其他查询锁住了。
Sending data
正在处理SELECT查询的记录,同时正在把结果发送给客户端。
Sorting for group
正在为GROUP BY做排序。
Sorting for order
正在为ORDER BY做排序。
Opening tables
这个过程应该会很快,除非受到其他因素的干扰。例如,在执ALTER TABLE或LOCK TABLE语句行完以前,数据表无法被其他线程打开。正尝试打开一个表。
Removing duplicates
正在执行一个SELECT DISTINCT方式的查询,但是MySQL无法在前一个阶段优化掉那些重复的记录。因此,MySQL需要再次去掉重复的记录,然后再把结果发送给客户端。
Reopen table
获得了对一个表的锁,但是必须在表结构修改之后才能获得这个锁。已经释放锁,关闭数据表,正尝试重新打开数据表。
Repair by sorting
修复指令正在排序以创建索引。
Repair with keycache
修复指令正在利用索引缓存一个一个地创建新索引。它会比Repair by sorting慢些。
Searching rows for update
正在讲符合条件的记录找出来以备更新。它必须在UPDATE要修改相关的记录之前就完成了。
Sleeping
正在等待客户端发送新请求.
System lock
正在等待取得一个外部的系统锁。如果当前没有运行多个mysqld服务器同时请求同一个表,那么可以通过增加--skip-external-locking参数来禁止外部系统锁。
Upgrading lock
INSERT DELAYED正在尝试取得一个锁表以插入新记录。
Updating
正在搜索匹配的记录,并且修改它们。
User Lock
正在等待GET_LOCK()。
Waiting for tables
该线程得到通知,数据表结构已经被修改了,需要重新打开数据表以取得新的结构。然后,为了能的重新打开数据表,必须等到所有其他线程关闭这个表。以下几种情况下会产生这个通知:FLUSH TABLES tbl_name, ALTER TABLE, RENAME TABLE, REPAIR TABLE, ANALYZE TABLE,或OPTIMIZE TABLE。
waiting for handler insert
INSERT DELAYED已经处理完了所有待处理的插入操作,正在等待新的请求。
大部分状态对应很快的操作,只要有一个线程保持同一个状态好几秒钟,那么可能是有问题发生了,需要检查一下。
还有其他的状态没在上面中列出来,不过它们大部分只是在查看服务器是否有存在错误是才用得着。
mysql 查看当前连接数
命令: show processlist;
如果是root帐号,你能看到所有用户的当前连接。如果是其它普通帐号,只能看到自己占用的连接。
show processlist;只列出前100条,如果想全列出请使用show full processlist;
mysql> show processlist;
命令: show status;
- mysql> show status;
