Nagios Support Forum

I am working on offline install of nagios xi. I followed the below steps

mkdir -p /tmp/rpms
cd /tmp/rpms
rm -rf nagiosxi*
wget https://repo.nagios.com/nagiosxi-offlin ... _64.tar.gz
tar xzf nagiosxi*
cd nagiosxi
./fullinstall

I manually added the missing configuration files to start nagios but after starting nagios I am unable to load the webinterface. Here are the errors I see in the HTTPD log.

Also I get the below message in the browser.

You don't have permission to access / on this server.

Or below when I try to reach /nagios

Please attach your /etc/httpd/conf/httpd.conf and your entire /etc/httpd/conf.d directory as it looks like a apache config issue.

Thank you

Also on top of what @ssax asked for, please attach your install.log from when it was initially installed.

Here is the install log. I have also listed the rpm -qa for MySQL and the requested info.

It doesn't appear the installation went as expected.

When you ran the offline install was this a clean minimal install system? This is required because the original setup of the mysql DB expects the it to not exist before installing.

What OS is this?

We are using centos6. Also I found we use a different version of MySQL. I version locked to use the version provided my centos6. But I am still seeing the below error.

Installation of system tables failed! Examine the logs in
/var/lib/mysql for more information.

You can try to start the mysqld daemon with:

shell> /usr/libexec/mysqld --skip-grant &

and use the command line tool /usr/bin/mysql
to connect to the mysql database and look at the grant tables:

shell> /usr/bin/mysql -u root mysql
mysql> show tables

Try 'mysqld --help' if you have problems with paths. Using --log
gives you a log in /var/lib/mysql that may be helpful.

Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
describes problems on your OS. Another information source are the
MySQL email archives available at http://lists.mysql.com/.

Please check all of the above before mailing us! And remember, if
you do mail us, you MUST use the /usr/bin/mysqlbug script!

Looks like your mysqld installation is broken.

What if you run these commands and try again:
Also, please send the output of this command:

I was able to resolve the mysql issue but now I am getting the below error.


/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h nagios1.devmlp.marquee.net password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

As I had mentioned earlier I am trying to integrate nagios-xi with our environment kickstart process. I am able to successfully install the tar ball after the kickstart But when I add it to the kickstart the install fails with iptables error message below. Any help is appreciated

I don't see any prior mention of kickstart, was this posted under a different forum account?

Running this through kickstart/anaconda might be part of the problem due to differences in environment variables, for example. If you run through the process manually instead of through KS and it works without issue, you might be better off posting this in a forum that deals with kickstart.
