本語句報告TCP/IP連接的主機名稱(採用host_name:client_port格式),以方便地判定哪個客戶端正在做什麼。
如果您得到“too many connections”錯誤信息,並且想要了解正在發生的情況,本語句是非常有用的。MySQL保留一個額外的連接,讓擁有SUPER權限的 賬戶使用,以確保管理員能夠隨時連接和檢查系統(假設您沒有把此權限給予所有的用戶)。

這個命令中最關鍵的就是state列,mysql列出的狀態主要有以下幾種:
Checking table
正在檢查數據表(這是自動的)。
Closing tables
正在將表中修改的數據刷新到磁盤中,同時正在關閉已經用完的表。這是一個很快的操作,如果不是這樣的話,就應該確認磁盤空間是否已經滿了或者磁盤是否正處於重負中。
Connect Out
複製從服務器正在連接主服務器。
Copying to tmp table on disk
由於臨時結果集大於tmp_table_size,正在將臨時表從內存存儲轉爲磁盤存儲以此節省內存。
Creating tmp table
正在創建臨時表以存放部分查詢結果。
deleting from main table
服務器正在執行多表刪除中的第一部分,剛刪除第一個表。
deleting from reference tables
服務器正在執行多表刪除中的第二部分,正在刪除其他表的記錄。
Flushing tables
正在執行FLUSH TABLES,等待其他線程關閉數據表。
Killed
發送了一個kill請求給某線程,那麼這個線程將會檢查kill標誌位,同時會放棄下一個kill請求。MySQL會在每次的主循環中檢查kill標誌位,不過有些情況下該線程可能會過一小段才能死掉。如果該線程程被其他線程鎖住了,那麼kill請求會在鎖釋放時馬上生效。
Locked
被其他查詢鎖住了。
Sending data
正在處理SELECT查詢的記錄,同時正在把結果發送給客戶端。
Sorting for group
正在爲GROUP BY做排序。
Sorting for order
正在爲ORDER BY做排序。
Opening tables
這個過程應該會很快,除非受到其他因素的干擾。例如,在執ALTER TABLE或LOCK TABLE語句行完以前,數據表無法被其他線程打開。正嘗試打開一個表。
Removing duplicates
正在執行一個SELECT DISTINCT方式的查詢,但是MySQL無法在前一個階段優化掉那些重複的記錄。因此,MySQL需要再次去掉重複的記錄,然後再把結果發送給客戶端。
Reopen table
獲得了對一個表的鎖,但是必須在表結構修改之後才能獲得這個鎖。已經釋放鎖,關閉數據表,正嘗試重新打開數據表。
Repair by sorting
修復指令正在排序以創建索引。
Repair with keycache
修復指令正在利用索引緩存一個一個地創建新索引。它會比Repair by sorting慢些。
Searching rows for update
正在講符合條件的記錄找出來以備更新。它必須在UPDATE要修改相關的記錄之前就完成了。
Sleeping
正在等待客戶端發送新請求.
System lock
正在等待取得一個外部的系統鎖。如果當前沒有運行多個mysqld服務器同時請求同一個表,那麼可以通過增加--skip-external-locking參數來禁止外部系統鎖。
Upgrading lock
INSERT DELAYED正在嘗試取得一個鎖表以插入新記錄。
Updating
正在搜索匹配的記錄,並且修改它們。
User Lock
正在等待GET_LOCK()。
Waiting for tables
該線程得到通知,數據表結構已經被修改了,需要重新打開數據表以取得新的結構。然後,爲了能的重新打開數據表,必須等到所有其他線程關閉這個表。以下幾種情況下會產生這個通知:FLUSH TABLES tbl_name, ALTER TABLE, RENAME TABLE, REPAIR TABLE, ANALYZE TABLE,或OPTIMIZE TABLE。
waiting for handler insert
INSERT DELAYED已經處理完了所有待處理的插入操作,正在等待新的請求。
大部分狀態對應很快的操作,只要有一個線程保持同一個狀態好幾秒鐘,那麼可能是有問題發生了,需要檢查一下。
還有其他的狀態沒在上面中列出來,不過它們大部分只是在查看服務器是否有存在錯誤是才用得着。
mysql 查看當前連接數
命令: show processlist;
如果是root帳號,你能看到所有用戶的當前連接。如果是其它普通帳號,只能看到自己佔用的連接。
show processlist;只列出前100條,如果想全列出請使用show full processlist;
mysql> show processlist;
命令: show status;
- mysql> show status;
