mysql设置最大连接数 max_connections
作者:互联网
mysql 5.7版本的配置文件为:/etc/mysql/mysql.conf.d/mysqld.cnf
查看最大连接数:
mysql> show variables like '%connection%'; +--------------------------+-----------------+ | Variable_name | Value | +--------------------------+-----------------+ | character_set_connection | utf8 | | collation_connection | utf8_general_ci | | max_connections | 151 | | max_user_connections | 0 | +--------------------------+-----------------+ 4 rows in set (0.49 sec)
设置最大连接数
mysql> set GLOBAL max_connections=2000; Query OK, 0 rows affected (0.00 sec) mysql> show variables like '%connection%'; +--------------------------+-----------------+ | Variable_name | Value | +--------------------------+-----------------+ | character_set_connection | utf8 | | collation_connection | utf8_general_ci | | max_connections | 2000 | | max_user_connections | 0 | +--------------------------+-----------------+ 4 rows in set (0.00 sec)
需要在配置文件中进行修改,否则重启数据库后会失效,可以同时修改变量值和配置文件中的变量值
