安裝 BIND(Named) Agent 的方式

返回 Ubuntu 20.04 / CentOS7 安裝 LibreNMS 程序

這是 SNMP Extend

named 服務的執行 user:group 是 named:named

至 bind/named 主機內安裝

mkdir -p /var/cache/bind
touch /var/cache/bind/stats
chown -R named:named /var/cache/bind
vi /etc/named.conf

:
options {
    ...
    statistics-file "/var/cache/bind/stats";
    zone-statistics yes;
    ...
};
:

重新啟動 named

systemctl restart named

執行檢查是否正確

rndc stats && cat /var/cache/bind/stats

如果正確, 應該會出現類似以下訊息

+++ Statistics Dump +++ (1594029813)

                 392 QUERY

安裝 bind agent

yum install epel-release 
yum install perl-File-ReadBackwards
wget https://github.com/librenms/librenms-agent/raw/master/snmp/bind -O /etc/snmp/bind
chmod +x /etc/snmp/bind
/etc/snmp/bind

執行後如果正確, 會出現類似以下訊息:
