Configure apache. File Location: usr/local/apache2/conf/http. conf

Change the process startup user to nagios, namely:

User nagios

Group nagios

LoadModule php5_module modules/libphp5.so # Remove the comment before this line

Find DirectoryIndex and add index. php

Added SetHandler application/x-httpd-php to support parsing php.

Add nagios configuration at the end:

ScriptAlias/nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow, deny
Allow from all
AuthName "Nagios Access"
AuthUserFile/usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
Alias/nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
AllowOverride None
Order allow, deny
Allow from all
AuthName "nagios Access"
AuthUserFile/usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>

Because the access authentication file is specified, you need to create one:

/Usr/local/apache2/bin/htpasswd-c/usr/local/nagios/etc/htpasswd [set your logon username] Press enter and enter the set password.

After the configuration is complete, you can start nagios and apache.

Problems:

Local access is allowed, and other hosts in the LAN are not accessible. If no router is reported, the firewall is blocked. You can turn off the server firewall: service iptables stop or add a new listener port 80 (http. conf) Rules: iptables-I INPUT-p tcp -- dport 80-j ACCEPT

After installing the server, you must configure the corresponding nagios file to monitor other hosts.
