今天线下测试 for update 结果把 测试机mysql 锁了

上网找了篇文章 亲测可用

    # 查询是否锁表
    
        
    mysql> show OPEN TABLES where In_use > 0;
    +-----------------+------------+--------+-------------+
    | Database        | Table      | In_use | Name_locked |
    +-----------------+------------+--------+-------------+
    | xx_trade_xx     | trust      |     47 |           0 |
    | xx_trade_xx     | user_xx    |      3 |           0 |
    +-----------------+------------+--------+-------------+
    找到了 user_xx 锁了三个... 
    # 查询进程

    [root@dev-server logs]# mysql -ppwd -ne 'show processlist' |grep user_xxx
    5919924 root    127.0.0.1:44032 xx_trade Query   24      Updating        UPDATE `user_xx` SET btc_lock =  btc_lock - 4159.9804 , `updated` = 1531056887\nWHERE `uid` = '1'\nAN
    5919956 root    127.0.0.1:44131 xx_trade Query   19      Updating        UPDATE `user_xx` SET btc_over =  btc_over + 2331.1115 , `updated` = 1531056892\nWHERE `uid` = '1'
    5920059 root    127.0.0.1:44634 xx_trade Query   3       Updating        UPDATE `user_xx` SET btc_over =  over + 757.3338 , `updated` = 1531056908\nWHERE `uid` = '1'
