我想很多朋友都有碰到过mysql服务器突然自动停止或又会自动启动吧,下面我们来分析一下原因与停止的解决办法. 分析原因二:可能是mysql连接问题 修改mysql的最大连接数, 使用内存变量修改法修改mysql的最大连接数 步骤如下,同时适用windows和linux平台: a、客户端登录mysql，输入用户名和密码’ b、在mysql命令提示符下设置新的最大连接数为500：mysql> set global max_connections=500 c、显示当前运行的query：mysql> show processlist d、显示当前mysql 系统参数状态：mysql> show status# k; e、退出客户端：mysql> exit’ 查看当前最大连接数只需要通过在mysqladmin所在目录下执行以下命令：mysqladmin -username -password variables |find “max_con” 即可看到。也可以使用php教程myadmin里头的mysql参数列表查看最大连接数。 缺点:重启计算机或者mysql后最大连接数又会复位成初始值，需要重新设定。 修改my.ini或my.cnf文件法（需要重启mysql），可参考同目录下mysql的配置模板（小内存、大内存、超大内存） . e windows系统下打开my.ini文件找到set-variable =max_connections=100这一行，改成需要设定的最大连接数，然后重启即可。 linux控制台下: 1、打开my.cnf文件：vi /etc/my.cnf 2 在[mysqld]段下修改max_connections的值为设定值。 注意:可能大家安装的mysql来源和版本不同,windows下mysql+iis和php+apache+mysql套件最终安装结果几乎都不相同,my.ini文件的路径可能有些不同，my.ini可能还会保留一份在c:windows目录下需要同时修改,这个方法是我在无意中发现的,经测试是可行的,下面拿出来和大家分享. 我的电脑 -> 右击 -> 服务 -> 找到 mysql服务 双击 新窗口中 -> 恢复 -> 第一次失败 设置为 重新启动服务. 下面重置失败计数 设置为0 重新启动服务 设置为0,就这样,就轻松搞定了mysql 自动停止的问题. 另外一种情况: 100904 22:37:27 InnoDB: Log file .ib_logfile0 did not exist: new to be created InnoDB: Setting log file .ib_logfile0 size to 10 MB InnoDB: Database physically writes the file full: wait... 100904 22:37:28 InnoDB: Log file .ib_logfile1 did not exist: new to be created InnoDB: Setting log file .ib_logfile1 size to 10 MB InnoDB: Database physically writes the file full: wait...
