nagios4.2.4 添加被监控端需要修改的文件
nagios4.2.4 添加被监控端Install:
epel源
yum install -y nagios
yum install -y nagios-plugins-all private 目录下面的resource.cfg 文件记录 插件位置
监控、被监控都需要nrpe
yum install -y nrpe /etc/nagios/nrpe.cfg 命令需要修改
安装完成以后
一、监控端
1、修改配置文件
vim/etc/nagios/nrpe.cfg
allow hosts = 127.0.0.1
/usr/lib64/nagios/plugins/ //各插件存放路径
vim /etc/nagios/objects/command.cfg
最后加入，支持pnp以及check_nrpe
#'check_nrpe' command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
# Bulk with NPCD mode
#
define command {
command_name process-service-perfdata-file
command_line /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$
}
define command {
command_name process-host-perfdata-file
command_line /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$
}
vim /etc/nagios/nagios.cfg
cfg_dir=/etc/nagios/servers //指定被监控的主机配置文件的存放路径
创建/etc/nagios/servers/s0.cfg 关于s0的相关监控项
可以自行添加监视的服务
define host{
use linux-server,host-pnp
host_name s0
alias s0
address 192.168.1.88
}
define service{
use generic-service,srv-pnp
host_name s0
service_descriptionload负载
check_command check_nrpe!check_load
}
二、被监控端
vim /etc/nagios/nrpe.cfg
allow hosts = 192.168.1.202 （监控端服务器）
/usr/lib64/nagios/plugins/ //执行命令存放的路径
在s0.cfg需要的命令在此文件中
command=/usr/lib64/nagios/plugins/check_service tomcat1 #检查tomcat1服务的状态，需要check_service这个监控插件 具体文件见百度云网盘
nrpe.cfg 里面加上command 以后 不重启nrpe 监控中会提示 check_tomcat1，没有定义
