"MySQL服务没有启动，请启动该服务."

俺不懂哇

你将你的mysql的配置文件贴出来,然后将你的服务器的内存还有你的论坛十五分钟在线人数这些信息都贴出来一下,我给你优化一下mysql,贴出来之后pm我一下!

8. #
   
9. # On Linux you can copy this file to /etc/my.cnf to set global options,
   
10. # mysql-data-dir/my.cnf to set server-specific options
    
11. # (@localstatedir@ for this installation) or to
    
12. # ~/.my.cnf to set user-specific options.
    
13. #
    
14. # On Windows you should keep this file in the installation directory
    
15. # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
    
16. # make sure the server reads the config file use the startup option
    
17. # "--defaults-file".
    
18. #
    
19. # To run run the server from the command line, execute this in a
    
20. # command line shell, e.g.
    
21. # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
    
22. #
    
23. # To install the server as a Windows service manually, execute this in a
    
24. # command line shell, e.g.
    
25. # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
    
26. #
    
27. # And then execute this in a command line shell to start the server, e.g.
    
28. # net start MySQLXY

内存是1G的
15分钟不好算,也有个1500左右了....

把max_connections=1500改为max_connections=500
query_cache_size=55M改为query_cache_size=32M,然后紧接下面加上
query_cache_type=1
wait_timeout=5,然后重启mysql!

灰常感谢!晚上在看一下.

22点出现这个了,是什么原因?
我把500改为700.
重启MYSQL提示错误,无法启动,只能喊机房重启服务器,最近都是这样.

论坛后台太壮观了

那个5.X的是5.0.27........

sort_buffer_size=2M
这项最重要
