查看进程，信息如下：

 
root     10630     1  0 Apr18 ?        00:00:00 /home/IHS/bin/httpd -f /home/IHS/conf/admin.conf
root     10631 10630  0 Apr18 ?        00:00:00 /home/IHS/bin/httpd -f /home/IHS/conf/admin.conf
nobody   10632 10630  0 Apr18 ?        00:00:00 /home/IHS/bin/httpd -f /home/IHS/conf/admin.conf
nobody   11956 10254  0 18:03 ?        00:00:03 /home/IHS/bin/httpd -d /home/IHS -k start

我感觉比较怪异的是：
1、

nobody   10254  1  0 18:03 ?        00:00:03 /home/IHS/bin/httpd -d /home/IHS -k start

这个进程的的启动用户应该是root才对，衍生的子进程才是nobody启动；
2、在I HS日志目录/home/IHS/logs只有

 
-rw-r--r--  1 root   root         7760 Jul 30  2011 admin_access_log
-rw-r--r--  1 root   root        16540 Apr 18 13:25 admin_error.log

没有产生apachectl这个任务的启动日志，连日志文件都没有产生；
3、日志目录空间没有满，日志目录文件个数没有超出linux限制；
4、80端口未被占用；
大家有没有遇到问题么？帮忙分析下。收起

Problem(Abstract)

IBM HTTP Server fails to startup and all that is observed in the error log are the following informational messages:

[Wed Oct 22 09:46:02 2008] [info] mod_unique_id: using ip addr
12.34.170.145
[Wed Oct 22 09:46:03 2008] [info] mod_unique_id: using ip addr
12.34.170.145
[Wed Oct 22 09:54:23 2008] [info] mod_unique_id: using ip addr
12.34.170.145
[Wed Oct 22 09:54:24 2008] [info] mod_unique_id: using ip addr
12.34.170.145

Symptom

IBM HTTP Server fails to start.

Cause
In this case, the plug-in was not being loaded by the httpd.conf during IBM HTTP Server startup.The plug-in was not being loaded as it could not read the http_plugin.log file.The log could not be read because the plug-in logs had reached 2 GB in size.Note: The 2GB limitation is due to the limitations set by a 32 bit JVM.
Diagnosing the problem

The preceding messages are not intuitive of the problem. Instead, the Web server simply stops loading if the plug-in log size is 2GB and, as a result, the error log is simply recording the last module that was successfully loaded. Which in this case is mod_unique_id.

Resolving the problem
Delete the plug-in log file.

Note: The location of the plug-in log file (for example: http_plugin.log) can be determined by viewing the LogLevel path line in the plugin-cfg.xml file.Restart the IBM HTTP Server and a new plug-in log file will be automatically created.
