服務端(192.168.2.110)無法訪問用戶端的NRPE: 

[[email protected] ~]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1

NRPE v2.12

[[email protected] ~]# /usr/local/nagios/libexec/check_nrpe -H 192.168.2.120

Connection refused by host

 

用戶端(192.168.2.120)：

[[email protected] etc]# lsof -i :5666

COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

nrpe    18703 nagios    4u  IPv4  85766      0t0  TCP localhost:5666 (LISTEN)#只在本地有效，所有外部的IP無法訪問

[[email protected] etc]# vim nrpe.conf +44

將以下內容注釋掉：

#server_address=127.0.0.1

[[email protected] etc]# pkill nrpe

[[email protected] etc]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

[[email protected] etc]# lsof -i :5666

COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

nrpe    18766 nagios    4u  IPv4  89670      0t0  TCP *:5666 (LISTEN)

這個就可以正常訪問了

 

服務端訪問：

[[email protected] etc]# /usr/local/nagios/libexec/check_nrpe -H 192.168.2.120 -c check_iostat

IOSTAT OK - user 0.28 nice 0.00 sys 0.30 iowait 0.31 idle 0.00  | iowait=0.31%;; idle=0.00%;; user=0.28%;; nice=0.00%;; sys=0.30%;;
