第二部分关于nrpe的安装

#!/bin/bash#INSTALL NRPE DAEMON#src=/home/nagios/srcnagios_home=/home/nagios/nagiosyum install openssl openssl-develuseradd nagiosgroupadd nagcmdusermod -a -G nagcmd nagiosecho "5cr8xOW7DF"|passwd --stdin nagiossu - nagiosmkdir ${src}cd ${src}wget http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gzwget http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gzecho "##INSTALL NAGIOS-PLUGINS##"tar xvf nagios-plugins-2.0.tar.gzcd nagios-plugins-2.0./configure --prefix=${nagios_home} --enable-perl-modulesmake && make installcd ${src}echo "##INSTALL NRPE##"tar xvf nrpe-2.15.tar.gzcd nrpe-2.15#编译启用参数传递./configure --prefix=${nagios_home} --with-nrpe-user=nagios --with-nrpe-group=nagios --enable-command-argsmake allmake install-pluginmake install-daemonmake install-daemon-configexitcd ${src}/nrpe-2.15/make install-xinetdsed -i 's/127.0.0.1/192.168.28.241/g' /etc/xinetd.d/nrpeecho "nrpe 5666/tcp # NRPE" >>/etc/serviceschown nagios. /etc/xinetd.d/nrpeservice xinetd restartlsof -i:5666

nrpe.cfg配置文件简单如下

log_facility=daemonpid_file=/var/run/nrpe.pidserver_port=5666server_address=127.0.0.1nrpe_user=nagiosnrpe_group=nagiosallowed_hosts=127.0.0.1 dont_blame_nrpe=1allow_bash_command_substitution=0debug=0command_timeout=60connection_timeout=300command[check_users]=/home/nagios/nagios//libexec/check_users -w $ARG1$ -c $ARG2$command[check_load]=/home/nagios/nagios//libexec/check_load -w $ARG1$ -c $ARG2$command[check_disk]=/home/nagios/nagios//libexec/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$command[check_procs]=/home/nagios/nagios//libexec/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$

其中server_address/allow_address注意根据实际修改，dont_blame_nrpe=1（默认为0,1为开启参数传递）

nagios server端command.cfg需另外define一个check_remote_nrpe的command

define command{ command_name check_remote_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$ $ARG3$ $ARG4$ }

这样监控服务，如客户端环境改变需调整参数的话只需要在nagios服务端修改参数即可，例如

define service{ use linux-service hostgroup_name 97f5eafb7a service_description check partition / check_command check_remote_nrpe!check_disk!20%!10%!/ }

第三部分，如果以后添加新监控点，则需去修改每台客户机的nrpe.cfg文件去define command，这样太麻烦了。所以再添加这样一个脚本来传递整个命令，客户端如需添加新监控点只需上传监控脚本，nagios服务端define service即可

#!/bin/shwhile getopts "a:c:" argdo case $arg in a) arg_a=$OPTARG; ;; c) arg_c=$OPTARG; ;; ?) echo "unkonw argument" echo "only -c -a argument" exit 1 ;; esacdoneif [[ "$arg_c" =~ "$HOME/" ]];then if [ ! -x $arg_c ];then echo "[$arg_c] not execute"; exit 3; fi $arg_c $arg_a; exit $?;else echo "cannt execute $arg_c,not allow execute [$HOME] outside scripts"; exit 3;fi

nagios的command文件需添加如下

define command{ command_name check_nrpe_exec command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$ }

客户端nrpe.cfg配置文件command部分只需要有

command[exec_command]=/home/nagios/nagios//libexec/exec_command -c exec_command -a "$ARG1$"

添加监控点例子，只需修改exec_command后的监控脚本命令

define service{ use linux-service host_name 887a34d257 service_description check_swap check_command check_nrpe_exec!"/home/nagios/nagios/libexec/check_swap -w 50% -c 30%" }
