yum install nagios nagios-devel nagios-plugins* gd gd-devel httpd php gcc glibc glibc-common
Bydefualt yum install nagios，在 cgi.cfg 文件中，提到了授权用户名 nagiosadmin 并使用 htpasswd 文件 /etc/nagios/passwd 文件。所以为了简单的步骤，我使用相同的名称。
# htpasswd -c /etc/nagios/passwd nagiosadmin
检查 /etc/nagios/cgi.cfg 中的以下给定值
nano /etc/nagios/cgi.cfg
# AUTHENTICATION USAGE use_authentication=1 # SYSTEM/PROCESS INFORMATION ACCESS authorized_for_system_information=nagiosadmin # CONFIGURATION INFORMATION ACCESS authorized_for_configuration_information=nagiosadmin # SYSTEM/PROCESS COMMAND ACCESS authorized_for_system_commands=nagiosadmin # GLOBAL HOST/SERVICE VIEW ACCESS authorized_for_all_services=nagiosadmin authorized_for_all_hosts=nagiosadmin # GLOBAL HOST/SERVICE COMMAND ACCESS authorized_for_all_service_commands=nagiosadmin authorized_for_all_host_commands=nagiosadmin
为了提供对 http 中 nagiosadmin 用户的访问权限，存在 /etc/httpd/conf.d/nagios.conf 文件。 下面是 nagios 服务器的 nagios.conf 配置。
cat /etc/http/conf.d/nagios.conf
