Too many database connections

Mysql Too many connections 、Mysql Handling the problem of too many connection errors

Two ways ：
1. Direct change mysql Connection number

  see mysql The maximum number of connections allowed  show variables like '%max_connections%' ;
  see mysql Number of connections used  show global status like'Max_used_connections';
  modify mysql The maximum number of connections allowed  set GLOBAL max_connections=1000;

2. stay mysql In the configuration file max_connections attribute

stay Windows The name of the configuration file in the system is my.ini stay Linux The name of the configuration file in is my.cnf

Below I post my own configuration. I use mysql8

[client]
default-character-set = utf8mb4
[mysql]
default-character-set=utf8mb4
[mysqld]
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
max_connections=1000
skip-character-set-client-handshake = true
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
