mysql查看当前连接数
1 查看当前连接数
SHOW STATUS LIKE 'Threads%';
Threads_connected显示的数值就是当前的连接数
2 查看连接到数据库的客户端ip及各连接数
SELECT substring_index(host, ':',1) AS host_name,state,count(*) FROM information_schema.processlist GROUP BY state,host_name;
3 查看连接到数据库的账号、客户端ip及各连接数
SELECT user,substring_index(host, ':',1) AS host_name,state,count(*) FROM information_schema.processlist GROUP BY state,host_name;
4 查看最大连接数
SHOW VARIABLES LIKE '%max_connections%';
5 如果要修改最大连接数为500
set global max_connections=500;
也可以修改mysql配置文件max_connections=500,然后重启mysql生效
如有错误欢迎指正
