3. log on to the service interface and verify that the above installation is correct.
Configure WEB interfaces
Make install-webconf # completed during nagios Installation
Create a nagiosadmin user for logging on to Nagios WEB Interface
[Root @ nagios] # htpasswd-c/usr/local/nagios/etc/htpasswd. users nagiosadmin
The htpasswd. users file does not exist by default. The-c parameter is automatically generated during creation (the first creation)
Restart the Apache service to make the settings take effect.
[Root @ nagios] # service httpd restart
[Root @ nagios] # service nagios restart
Http: // ip/nagios # access the nagios server to verify whether the installation is successful
The system prompts that you do not have the permission to access the nagios server. You can use the chmod command to change the permission of the apache service directory because the nagios user has the permission to access
If you can log on to the home page, but the function on the left side cannot display a prompt indicating that the internal server is abnormal, you can change the selinux configuration.
If you do not disable SELinux or change SELinux permanently, you can enable the CGI Module to specify the forced target mode under SELinux:
[Root @ nagios] # chcon-r‐t httpd_sys_content_t/usr/local/nagios/sbin/
[Root @ nagios] # chcon-r‐t httpd_sys_content_t/usr/local/nagios/share/
