MySQL show processlist命令详解及查看当前连接数




官网:https://dev.mysql.com/doc/refman/5.6/en/show-processlist.html





select * from information_schema.processlist ;



SHOW PROCESSLIST显示哪些线程正在运行。您也可以使用mysqladmin processlist语句得到此信息。如果您有SUPER权限,您可以看到所有线程。否则,您只能看到您自己的线程(也就是,与您正在使用的MySQL账户相关的线程)。请参见13.5.5.3节,“KILL语法”。如果您不使用FULL关键词,则只显示每个查询的前100个字符。

Tengine、Nginx安装MySQL数据库命令教程
本指南详细介绍了在Linux系统上安装与配置MySQL数据库的步骤。首先通过下载并安装MySQL社区版本,接着启动MySQL服务,使用`systemctl start mysqld.service`命令。若启动失败,可尝试使用`sudo /etc/init.d/mysqld start`。利用`systemctl status mysqld.service`检查MySQL的服务状态,确保其处于运行中。通过日志文件获取初始密码,使用该密码登录数据库,并按要求更改初始密码以增强安全性。随后创建一个名为`tengine`的数据库,最后验证数据库创建是否成功以及完成整个设置流程。
