篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Nagios中用于nrpe的启动管理脚本相关的知识,希望对你有一定的参考价值。
最近一段时间应为需要大量的调整修改Nagios的监控策略所以需要反复的重启nrpe,但是在Nagios安装后是没有提供nrpe的启动脚本,所以就自己顺手写了一个用于平时nrpe的重启:
#!/bin/sh #The startup script for nrpe #Author:jim #processname:nrped # chkconfig: 2345 97 03 #description:This is a daemon used for nrpe startup management in Nagios #source functions library if [ -f /etc/rc.d/init.d/functions ]; then . /etc/rc.d/init.d/functions elif [ -f /etc/init.d/functions ]; then . /etc/init.d/functions elif [ -f /lib/lsb/init-functions ]; then . /lib/lsb/init-functions fi prefix="/usr/local/nagios" nrpe_bin="${prefix}/bin/nrpe" nrpe_config_file="${prefix}/etc/nrpe.cfg" nrpe_num=$(ps aux | grep /bin/nrpe | grep -v grep | wc -l) nrpe_pid=$(ps aux | grep /bin/nrpe | grep -v grep | awk ‘{print $2}‘) RETVAL=0 start() { if [ $nrpe_num -eq 1 ];then echo_warning echo "nrpe is running " else ${nrpe_bin} -c ${nrpe_config_file} -d echo_success echo "Starting nrpe " fi } stop() { if [ $nrpe_num -eq 1 ];then kill -9 $nrpe_pid echo_success echo "Starting nrpe " else echo_failure echo "nrpe is stoping " fi } restart() { if [ $nrpe_num -eq 1 ];then kill -9 $nrpe_pid echo_success echo "Stopting nrpe " ${nrpe_bin} -c ${nrpe_config_file} -d echo_success echo "Starting nrpe " else echo_failure echo "nrpe is stoping " ${nrpe_bin} -c ${nrpe_config_file} -d echo_success echo "Starting nrpe " fi } case $1 in start) start ;; stop) stop ;; restart) restart ;; *) echo_failure echo "Usage: $0 {start|stop|restart}" RETVAL=2 esac exit $RETVAL
总之来说还是比较简单的,其中有使用到系统的functions,可以参看:http://jim123.blog.51cto.com/4763600/1900432,其中要注意的一点是,把文件上传至/etc/init.d目录后需要授予执行权,然后用chkconfig加入系统中使service能管理到,如果是Linux/Centos 7的系统还要使用systemctl daemon-reload重载一次:
[[email protected] init.d]# chmod +x nrped [[email protected] init.d]# chkconfig --add nrped chkconfig --list nrped systemctl daemon-reload[[email protected] init.d]# chkconfig --list nrped nrped 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭 [[email protected] init.d]# /etc/init.d/nrped restart Stopting nrpe [确定] Starting nrpe [确定] [[email protected] init.d]# service nrped restart Stopting nrpe [确定] Starting nrpe [确定]
