问题描述
当我运行 show status like 'Con%' 时，它会显示连接数，即 9972，并且还在不断增长.这是活跃的连接数还是总连接数?
When I run show status like 'Con%' it shows the number of connections, which is 9972 and constantly growing. Is this an active number of connections or connections made in total?
推荐答案
根据文档，表示整个历史的总数:
According to the docs, it means the total number throughout history:
连接
与 MySQL 服务器的连接尝试次数(成功与否).
The number of connection attempts (successful or not) to the MySQL server.
您可以通过 活动 连接的数量.html#statvar_Threads_connected" rel="noreferrer">Threads_connected 状态变量:
You can see the number of active connections either through the Threads_connected status variable:
Threads_connected
当前打开的连接数.
mysql> show status where `variable_name` = 'Threads_connected';
+-------------------+-------+
| Variable_name | Value |
+-------------------+-------+
| Threads_connected | 4 |
+-------------------+-------+
1 row in set (0.00 sec)
...或通过show processlist命令:
mysql> show processlist;
+----+------+-----------------+--------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+------+-----------------+--------+---------+------+-------+------------------+
| 3 | root | localhost | webapp | Query | 0 | NULL | show processlist |
| 5 | root | localhost:61704 | webapp | Sleep | 208 | | NULL |
| 6 | root | localhost:61705 | webapp | Sleep | 208 | | NULL |
| 7 | root | localhost:61706 | webapp | Sleep | 208 | | NULL |
+----+------+-----------------+--------+---------+------+-------+------------------+
4 rows in set (0.00 sec)
