====== 安裝 BIND(Named) Agent 的方式 ======
  * 返回 [[tech:librenms]]

  * 這是 SNMP Extend

  * named 服務的執行 user:group 是 named:named

  * 至 bind/named 主機內安裝 <code sh>
mkdir -p /var/cache/bind
touch /var/cache/bind/stats
chown -R named:named /var/cache/bind
vi /etc/named.conf</code><file>
:
options {
    ...
    statistics-file "/var/cache/bind/stats";
    zone-statistics yes;
    ...
};
:
</file>重新啟動 named <code sh>
systemctl restart named</code>
  * 執行檢查是否正確<code sh>
rndc stats && cat /var/cache/bind/stats
</code>如果正確, 應該會出現類似以下訊息<cli>

  * 安裝 bind agent <code sh>
