nrpe启动服务service xinetd restart查看NRPE是否已经启动rootdbpi nrpe-2.8.1# netstat -at|grep nrpetcp 0 0 *:nrpe *:* LISTEN rootdbpi nrpe-2.8.1# netstat -an|grep 5666tcp 0 0 :5666 :* LISTEN 可以看到5666端口已经在监听了5.测试NRPE是否则正常工作之前我们在安装了check_nrpe这个插件用于测试,现在就是用的时候.执行/usr/local/nagios/libexec/check_nrpe -H localhost会返回当前NRPE的版本rootdbpi nrpe-2.8.1# /usr/local/nagios/libexec/check_nrpe -H localhostNRPE v2.12通过ndoutils降nagios数据信息放到数据库配置数据库补充安装包rpm -Uvh mysql-devel-5.0.45-7.el5.i386.rpm (mysql apache 都是采用系统安装时自带的rpm包)service mysqld startmysql -uroot -pmysql -u root -pmysql CREATE DATABASE nagios;mysqlGRANT ALL PRIVILEGES ON nagios.* TO nagioslocalhost IDENTIFIED BY nagios;安装ndoutils /download/tar -zxvf ndoutils-1.4b7.tar.gzcd ndoutils-1.4b7./configure -prefix=/usr/local/nagios-enable-mysqlmake all设置ndo2db和ndomodcp ndo2db-3x /usr/local/nagios/bin/ /ndo2db可执行文件cp ndomod-3x.o /usr/local/nagios/bin/ /ndomod库文件cp config/ndo2db.cfg /usr/local/nagios/etc/ndo2db配置文件cp config/ndomod.cfg /usr/local/nagios/etc/ndomod配置文件注意权限和属组vi /usr/local/nagios/etc/nagios.cfg 找到broker_module添加broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg建立数据库：cd dbvi installdb修改DBI:mysql:database=$database;host=$hostname 的host=改成了，localhost./installdb-unagios -pnagios -d nagios 这里会包错误DBD:mysql:db do failed: Table nagios.nagios_dbversion doesnt exist at ./installdb line 51不用管它 登陆数据库nagiosmysql -unagios -pnagios use nagiosshow tables;看到有表就可以了alter table nagios_configfilevariables drop key instance_id;alter table nagios_configfilevariables add index (instance_id, configfile_id, varname) ;编辑vi /usr/local/nagios/etc/ndo2db.cfg 建立与数据库连接的内容ndo2db_user=nagiosndo2db_group=nagiosdb_servertype=mysqldb_host=localhostdb_port=3306db_name=nagiosdb_user=nagiosdb_pass=nagios修改接口socket_type=unix启动apache+nagios+mysql+ndo2db启动的shell# up apacheservice httpd start#up nagios/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg#up mysqlservice mysqld start#up ndo2db/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg查看日志tail -f /usr/local/nagios/var/nagios.logtail -f /var/lo
