Apache 2.2.6 连接数出现问题，

冰力

现在调试一台服务器，

但是当连接数达到 20 的时候整个 Apache 服务器都无法连接，

无论多少个站点，

但是我 ssh 服务器都很正常，

只是 WEB 服务受到影响，

测试服务器地址：
server.itbbs.cn

服务器 IP 地址：
221.130.197.30

这样的效果一般应该会是什么原因？谁知道，谢谢，

你看看你的 apache 的 httpd.conf 文件里的 MaxClients

冰力

没有这个，但是，是所有站点的连接数，我从来没有特意限制过，不知道怎么回事，

alvis

沒有哪個？

你把你 apache 的配置文件貼出來看看

1. #
   
2. # This is the main Apache HTTP server configuration file.  It contains the
   
3. # configuration directives that give the server its instructions.
   
4. # See <URL:[url]http://httpd.apache.org/docs/2.2[/url]> for detailed information.
   
5. # In particular, see
   
6. # <URL:[url]http://httpd.apache.org/docs/2.2/mod/directives.html[/url]>
   
7. # for a discussion of each configuration directive.
   
8. #
   
9. # Do NOT simply read the instructions in here without understanding
   
10. # what they do.  They're here only as hints or reminders.  If you are unsure
    
11. # consult the online docs. You have been warned.  
    
12. #
    
13. # Configuration and logfile names: If the filenames you specify for many
    
14. # of the server's control files begin with "/" (or "drive:/" for Win32), the
    
15. # server will use that explicit path.  If the filenames do *not* begin
    
16. # with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
    
17. # with ServerRoot set to "/usr/local/apache" will be interpreted by the
    
18. # server as "/usr/local/apache/logs/foo.log".
    
19. 
    
20. #
    
21. # ServerRoot: The top of the directory tree under which the server's
    
22. # configuration, error, and log files are kept.
    
23. #
    
24. # Do not add a slash at the end of the directory path.  If you point
    
25. # ServerRoot at a non-local disk, be sure to point the LockFile directive
    
26. # at a local disk.  If you wish to share the same ServerRoot for multiple
    
27. # httpd daemons, you will need to change at least LockFile and PidFile.
    
28. #
    
29. ServerRoot "/usr/local/apache"

34. # directive.
