記錄一下在 ubuntu 20.04 (LXC) 安裝nfsen
OS布署完成後先update
apt update
apt upgrade -y
再來修改時區
timedatectl set-timezone Asia/Taipei
安裝所需 package
apt install -y nfdump rrdtool librrd-dev librrds-perl librrdp-perl libpcap-dev php php-common libsocket6-perl apache2 libapache2-mod-php libmailtools-perl libio-socket-ssl-perl
下載 nfsen
從官方下載的版本在安裝時會出現以下的 bug
Can't use string ("live") as a HASH ref while "strict refs" in use at libexec/NfProfile.pm line 1238.
因此從 https://github.com/p-alik/nfsen/releases/tag/nfsen-1.3.8 下載已修正版本
下載後解壓縮
cd nfsen-nfsen-1.3.8/etc
cp nfsen-dist.conf nfsen.conf
決定安裝路徑在 /opt/nfsen
修改 nfsen.conf
$BASEDIR = "/opt/nfsen";
$PREFIX = '/usr/bin/';
$USER = "www-data";
$WWWUSER = "www-data";
$WWWGROUP = "www-data";
%sources = ( 'upstream1' => {'port'=>'9995','col'=>'#0000ff','type'=>'netflow'}' );
mkdir /opt/nfsen
mkdir /var/www/html/nfsen
adduser netflow
安裝
./install.pl ./etc/nfsen.conf
出現
RRD version '1.7002' not yet supported!
需修改 libexec/NfSenRRD.pm 約在第 76 行 改成 ==> $rrd_version >= 1.2 && $rrd_version < 1.9
再執行一次
./install.pl ./etc/nfsen.conf
啟動
/opt/nfsen/bin/nfsen start
設定開几啟動
cd /etc/systemd/system
ln -s /lib/systemd/system/rc-local.service
vi /etc/rc.local
#!/bin/sh -e
/usr/local/nfsen/bin/nfsen start
exit 0
chmod +x /etc/rc.local
設定開几不啟動nfdump 因為nfsen啟動時會自行呼叫
systemctl disable nfdump.service
重開几
設定 netflow 導到 udp 9995
打開 http://nfsen_ip/nfsen/nfsen.php 確認是否正常
