mysql SHOW PROCESSLIST命令詳解

SHOW PROCESSLIST顯示哪些線程正在運行。您也可以使用mysqladmin processlist語句得到此信息。如果您有SUPER權限,您可以看到所有線程。否則,您隻能看到您自己的線程(也就是,與您正在使用的MySQL賬戶相關的線程)。如果您不使用FULL關鍵詞,則隻顯示每個查詢的前100個字符。

本語句報告TCP/IP連接的主機名稱(采用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,並且想要瞭解正在發生的情況,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瞭或者磁盤是否正處於重負中。

Connect Out

復制從伺服器正在連接主伺服器。

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為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

伺服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

伺服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

發送瞭一個kill請求給某線程,那麼這個線程將會檢查kill標志位,同時會放棄下一個kill請求。MySQL會在每次的主循環中檢查kill標志位,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瞭,那麼kill請求會在鎖釋放時馬上生效。

Locked

被其他查詢鎖住瞭。

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

正在為GROUP BY做排序。

Sorting for order

正在為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幹擾。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復的記錄。因此,MySQL需要再次去掉重復的記錄,然後再把結果發送給客戶端。

Reopen table

獲得瞭對一個表的鎖,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瞭。

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伺服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

正在搜尋匹配的記錄,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瞭,需要重新打開數據表以取得新的結構。然後,為瞭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已經處理完瞭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,隻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瞭,需要檢查一下。

還有其他的狀態沒在上面中列出來,不過它們大部分隻是在查看伺服器是否有存在錯誤是才用得著。

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,隻能看到自己占用的連接。

show processlist;隻列出前100條,如果想全列出請使用show full processlist;

mysql> show processlist;

命令: show status;
