1. 查找my.cnf文件的位置，根据Linux发行版和安装类型可能位于`/etc/mysql/my.cnf`、`/etc/my.cnf`或自定义映射位置。2. 将max_connections参数配置到`[mysqld]`下面。3. 重启MySQL服务以使更改生效。对于个人搭建的Docker环境，只需重启镜像即可。可以使用Docker ID模糊匹配或自定义名称后进行重启。
这意味着所有可用的连接已经被各种客户端使用,你的MySQL服务器不能打开任何新的连接,直到任何现有的连接被关闭。 By default, MySQL 5.5+ can handle up to 151 connections. This number is stored in server variable calledmax_connections. You can update max_connections variable to increase maximum supported ...
You can change the setting to e.g. 200 by issuing the following command without having to restart the MySQL server (obviously it will only work if the user you are logged in as has sufficient permissions to do this): set global max_connections = 200; This will take effect immediately, b...
And just to check: setting themax_connectionstoo high will result in the mysql server crashing with an "Out of memory" error if you get too many active threads, right? Finally, we've noticed that we have one database where we've setmax_connectionsas high as we think is safe, but we...
有两种方法来增加MySQL连接。下面是通过MySQL命令行工具更新最大连接数为200的命令,无需重新启动。 1. 临时修改:命令 通过Mysql连接到客户端,可以使用下面的命令修改最大连接数: 代码语言:javascript 复制 mysql>setglobal max_connections=200; 但是需要注意这种修改方式一旦重启就会失效,所以这个命令通常是在出现类似...
set global max_connections = 200; This will take effect immediately, but will be forgotten the next time MySQL is restarted. To make the change permanent you need to edit the my.cnf configuration file. On CentOS, RedHat and similar distributions this is at /etc/my.cnf; other distros will...
If I use the c API, Can use the mysql_close(&mysql); But I dont know how to use the Connect/c++ to close the connectionHow to repeat:try { sql::Driver *driver; sql::Connection *con; sql::Statement *stmt; sql::ResultSet *res; /* Create a connection */ driver = get_driver_in...
This stems from MySQL’s use of standalone values for both mysqld and the client. Hence, the value you get from the SHOW VARIABLES LIKE ‘max_allowed_packet’ command refers to the max value on the server side. To set the max value on the client side, we can run the command: ...
%plesk_dir%DatabasesMySQLmy.inifile in a text editor. Add themax_connectionsparameter with a required value under the [mysqld]section: max_connections=150 Save the changes and close the file. Restart theMySQL/MariaDB XXservice via Plesk Services Monitor to apply changes:...
NOTE : If you want this setting to be permanent, then you need to change this in the my.cnf file on the mysql server host otherwise a restart of the mysqld process will only take the setting from the my.cnf file or the default (if there is no max_allowed_packet) in my.cnf. ...
