1.mysql初始默认支持的最大连接数为151(目前我本地安装的mysql默认大小,可能不准确)

2.一般情况下,我们可能需要mysql支持更多的连接数,比如说200,那么我们按照以下步骤进行设置

第一步:连接mysql

使用mysql -uxxxx -pxxxx进行登录

第二步:使用以下命令得到最大连接数

mysql> show variables like 'max_connections';+-----------------+-------+| Variable_name | Value |+-----------------+-------+| max_connections | 151 |+-----------------+-------+1 row in set
Copy after login

可以看到最大连接数为151。

第三步:使用以下命令设置mysql的最大连接数

mysql> set global max_connections = 200;Query OK, 0 rows affected
Copy after login

然后再使用show variables like 'max_connections';命令进行查看,可以发现最大连接数已经变成为200。
