nagios監控haproxy（借助腳本）
修改后的腳本如下（需添加指示燈的狀態）
# vi haproxy.sh
#!/bin/bash
Port=`netstat -ntpl | grep haproxy | awk -F[:" "]+ '{print $5}'`
if [ $Port == "1080" ];then
echo "OK - haproxy is running"?
exit 0
else
echo "CRITICAL - haproxy is down"?
/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg
exit 2
fi
???
:wq
注：0 指的是狀態燈綠燈，2指的是紅燈，黃燈不用???? 并且宕了之后再次check時就能自動重啟
# cp haproxy.sh? /usr/local/nagios/libexec
# chmod +x /usr/local/nagios/libexec/haproxy.sh
?
# mount /dev/cdrom /media/cdrom
# rpm -ivh sudo-1.6.9pl7-3.el5.i386.rpm
# visudo
#Defaults??? requiretty??????? (注釋掉)
nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/haproxy.sh??? (多個腳本的話設置多行)
?
:wq
?
# su - nagios -c 'sudo /usr/local/nagios/libexec/haproxy.sh'??? (看看執行是否成功)
?
# vi /usr/local/nagios/etc/nrpe.cfg
?
command[check_haproxy]=/usr/bin/sudo /usr/local/nagios/libexec/haproxy.sh
?
:wq
?
# killall nrpe
?
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
