如何修改mysql_connections和其他参数的大小(我记得好像有人问过)

example mysql nbsp variable

connection|mysql

记得以前有网友在这里问过如何修改mysql的最大连接数的问题,好像没有得到完整的回答(我记得好像是),今天突然收到csdn的一位网友发来邮件询问这个问题,于是就到mysql的站点上去寻找答案,不过很令我失望的是,我没有找到具体的解决办法(可能是我不太细心的缘故),突然想起在dos下可以通过命令修改的,不过进入dos后,看帮助,怎么也没想起来原来的看过的命令(记性不好还没有及时保存下来),没办法,只得退出dos重新查找资料,再退出的时候我突然发现在mysql目录下有一个my-example.cnf文件(在windows下没有看到,显示所有隐藏文件也没有看到).cnf文件不就是config?于是我就将其打开,终于我找到了答案!解决的办法如下:

在程序-〉运行中执行:notepad yourmysqlpath/my-example.cnf,把my-example.cnf文件的内容拷贝到一个新建文本文件中,找到[mysqld],看到在它的下边有一些诸如set-variable =的话了吧?在最后一个set-variable =后边加上  set-variable    = max_connections=你希望的数字,然后把文本文件另存为c:/my.cnf文件(如果你有这个文件,就直接修改它),这个时候你在dos下进入mysql下的bin目录,执行mysqld --help,执行之后你会看到max_connections的值就是你在上面填写的值。其它系统变量的修改和修改max_connections的方法类似。

所以细心,多看文档的好处是显而易见的,在编程中更是如此,大家应该比我清楚这点,我还是没有找到直接用命令来修改参数的方法(当然后来也没找),如果那位网友知道或者发现了,请无私的讲出来,谢谢了!

不管怎样问题还是解决了(请大家不要嫌我罗嗦),最后祝大家中秋节快乐!送大家几块不太像的月饼!@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@(够分了吧?至少够wayne.xiao吃了,因为这里就我和他在线,不过我估计这个家伙是忘了关浏览器了,也许他根本没在线!!!!!)
