Flare OE and NAS upgrades. Unable to access the Unisphere Web Interface after an OE Flare and NAS code upgrade. Unisphere became inaccessible, the httpd.conf file reverted back to default and upon editing an extra space was entered causing problems with the Apache script.
Customer had to reedit the /nas/http/conf/httpd.conf after an upgrade as the file reverts back to default settings. In this case, the customer had to readd security Ciphers on the SSLCipherSuite line. However, any mistake in editing such as leaving an extra space in the file can cause the Apache script to fail.
To confirm a problem with the httpd.conf file, check error instances regarding Apache and Tomcat 'unexpectedly exited' using the following commands: /nas/tools/dbchk -wvxpV nas_logviewer /nas/log/sys_log | grep -i apache | tail nas_logviewer /nas/log/sys_log | grep -i tomcat | tail cat /var/log/messages | grep -i tomcat | tail cat /var/log/messages | grep -i apache | tail cat /nas/tomcat/logs/catalina.out | grep -i error | tail Check for syntax errors in the apache_restart.out file using the following command: cat /nas/http/logs/apache_restart.out | grep -i syntax | tail To confirm issues with the httpd.conf: Do a vi or less on /nas/http/conf/httpd.conf file and search for the line number that you see w/ the syntax error from apache_restart.out. And then check the same file and line number on a lab array to determine where the extra space or incorrect/missing character is and edit to resolve. After confirming an edit issue with the httpd.conf file: For the SSLCipherSuite example, you would vi edit and remove the extra space on that line to change it from one line broken into two lines back to a single line: < # SSL Cipher Suite: < # List the ciphers that the client is permitted to negotiate. < # See the mod_ssl documentation for a complete list. < #SSLCipherSuite ALL:!ADH:!DH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:-MEDIUM:-LOW < SSLCipherSuite < ALL:!ADH:!DH:!EXPORT:!SSLv2:+HIGH:-MEDIUM:-LOW After removing the extra space, it would then look like this: < # SSL Cipher Suite: < # List the ciphers that the client is permitted to negotiate. < # See the mod_ssl documentation for a complete list. < #SSLCipherSuite ALL:!ADH:!DH:!EXPORT:!SSLv2:+HIGH:-MEDIUM:-LOW < SSLCipherSuite ALL:!ADH:!DH:!EXPORT:!SSLv2:+HIGH:-MEDIUM:-LOW After fixing the editing mistake in the httpd.conf file, confirm that the errors have stopped by reviewing the logs again with: tail -f on /var/log/messages And /nas/http/logs/apache_restart.out The errors tend to be streaming and stop right after you fix the problem edit. Remember: The above is an example to show a space added to a single line breaking it up and causing it to be two separate lines in the file. But you would have to assess on a case by case basis and fix accordingly be it extra spaces, removed spaces, or typos.
