My box is scientific linux x64 6.2.

I've installed apache,mysq,php, and start apche, but failed.

Quote:
[root@linux Documents]# service httpd configtest
httpd: Syntax error on line 32 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_auth_basic.so into server: /etc/httpd/modules/mod_auth_basic.so: cannot open shared object file: No such file or directory
[root@linux Documents]# locate mod_auth_basic.so/
/usr/lib64/httpd/modules/mod_auth_basic.so
please let me know how to resolve this problem.

Thanks in advance.

Hi,

In RHEL based distros (like scientific linux) /etc/httpd/modules is a symlink for /usr/lib64/httpd/modules, so check if the symlink exists, or you have to re-create it

Regards

I'm very please to meet you again. I remember your kind help about dns settings, and whenever I re-install linux I check your guide.

Hi windstory,

You should do the symlink the other way around.
Code:
ln -s /usr/lib64/httpd/modules /etc/httpd
Cheers mate

Looks like installation completed successfully. I don't think yum reports any file being installed. Check if the various apache modules exist in /usr/lib64/httpd/modules.

This is just a warning. You can set ServerName to something like localhost or www.example.com, so apache stops complaining
Quote:

What gives:
Code:
ls -ld /var/log/httpd
ls -l /var/log/httpd

Looks good.
What's in /var/log/httpd/error_log?
Also did you check if the modules are installed under /usr/lib64/httpd/modules and there exist the symlink to /etc/httpd/modules?

I found an error at httpd.confand correct it.

Code:
ErrorLog logs/error_log
But, still error message exist. The "error_log" file is at "/var/log/httpd", but apache searchs at "/etc/httpd/logs".

Quote:

I changed "ErrorLog" as this,

Code:
ErrorLog logs/error_log
Then;

Quote:
(2)No such file or directory: httpd: could not open error log file /usr/sbin/rotatelogs /var/log/httpd/myserver5.test.net_access_log.%Y-%m-%d 86400 +540.
Unable to open logs
Actually there are 5 vhosts in "/etc/httpd/conf.d/vhost.conf", but only "myserver5.test.net" has an error.

The "/etc/httpd/conf.d/vhost.conf" is this;

Code:
<VirtualHost *:80>
ServerAdmin webmaster@server5.net
DocumentRoot /var/www/html/myserver5
ServerName myserver5.test.net
ServerAlias www.myserver5.test.net
CustomLog "/usr/sbin/rotatelogs /var/log/httpd/myserver5.test.net_access_log.%Y-%m-%d 86400 +540" common
ErrorLog "/usr/sbin/rotatelogs /var/log/httpd/myserver5.test.net_error_log.%Y-%m-%d 86400 +540" 
</VirtualHost>
And,
Quote:
[root@linux httpd]# cat logs/error.log
cat: logs/error.log: No such file or directory

I don't know what's wrong with your installation, but you can use the full path to the logs, e.g.:
Code:
ErrorLog "/var/log/httpd/error_log"
Regarding rotatelogs, you've forgotten the initial pipe:
Code:
CustomLog "|/usr/sbin/rotatelogs /var/log/httpd/myserver5.test.net_access_log.%Y-%m-%d 86400 +540" common
