1、事前準備

■以下のファイルを対象サーバの任意の場所に配置
※本件では/tmp を使用する。
snmptt_1.4.tgz
perl-Config-IniFiles-2.83-4.1.noarch.rpm
perl-Net-SNMP-v5.0.1-1.pp-rh73.noarch.rpm

2、パッケージ のインストール

■yum からインストールを実行

# yum -y install perl-Crypt-DES perl-Digest-HMAC perl-Digest-SHA perl-Socket6 perl-Crypt-DES

# yum -y install perl-Sys-Syslog perl-List-MoreUtils perl-IO-stringy
# yum -y install net-snmp-utils net-snmp-perl perl perl-Net-SNMP perl-Config-IniFiles perl-Module-Build perl-Time-HiRes
# yum -y install perl-Digest-SHA1
# rpm -ivh perl-Config-IniFiles-2.83-4.1.noarch.rpm perl-Net-SNMP-v5.0.1-1.pp-rh73.noarch.rpm

# useradd -s /sbin/nologin snmptt

# cd /tmp
# cp -p snmptt_1.4.tgz /usr/src
# cd /usr/src
# tar xvfz snmptt_1.4.tgz

# cd snmptt_1.4

# cp ./snmptt /usr/sbin
# cp ./snmptthandler /usr/sbin/
# cp ./snmptthandler-embedded /usr/sbin/
# cp ./snmptt.ini /etc/snmp/
# cp ./snmpttconvertmib /usr/sbin/

# chmod 755 /usr/sbin/snmptt
# chmod 755 /usr/sbin/snmptthandler
# chmod 755 /usr/sbin/snmptthandler-embedded
# chmod 755 /usr/sbin/snmpttconvertmib

# mkdir /var/log/snmptt
# chown snmptt:snmptt /var/log/snmptt
# mkdir /var/spool/snmptt/
# chown snmptt:snmptt /var/spool/snmptt/

# cp snmptt-init.d /etc/rc.d/init.d/snmptt

# cd /usr/lib/systemd/system
# pwd

# touch snmptt.service
# vi snmptt.service

[Unit]
Description=SNMP Trap Translator
Wants=network-online.target
After=syslog.target network-online.target

[Service]
Environment="CONFIG=/etc/snmp/snmptt.ini"
ExecStart=/usr/sbin/snmptt -c ${CONFIG}
ExecReload=/bin/kill -HUP ${MAINPID}
Type=forking
PIDFile=/var/run/snmptt.pid
Restart=always
TimeoutStopSec=320s
KillMode=process
RestartSec=5s

[Install]
WantedBy=multi-user.target

# systemctl daemon-reload

# cd /usr/src/snmptt_1.4
# cp snmptt.logrotate /etc/logrotate.d/snmptt

3、関連ファイルの設定

■設定ファイルの編集
# cd /etc/snmp/
# vi snmptt.ini

以下の様に編集

# mode = standalone
mode = daemon

# net_snmp_perl_enable = 0
net_snmp_perl_enable = 1

# net_snmp_perl_best_guess = 0
net_snmp_perl_best_guess = 2

\# date_time_format =
date_time_format = %Y/%m/%d %Y %H:%M:%S

# sleep = 5
sleep = 1

# syslog_enable = 1
syslog_enable = 0

■メッセージファイルの編集
# vi snmptt.conf

以下の様に編集

EVENT general .* "LOGONLY" Normal
FORMAT zabbixtrap $aA $ar で未知のSNMP Trapが送信されました。$-*

■プロセスを起動
# systemctl start snmptt
# systemctl status snmptt
# systemctl enable snmptt
# systemctl is-enabled snmptt

■snmptrapdの設定を変更
# cd /etc/sysconfig/
# vi snmptrapd

以下の様に編集

OPTIONS="-m +ALL -On"

■プロセスを再起動
# systemctl restart snmptrapd
# systemctl restart snmptt

# cd /var/log/snmptt/
# touch snmptt.log
# chown snmptt:snmptt snmptt.log

■テスト
# snmptrap -v2c -c localhost '' .1.3.6.1.6.3.1.1.5.3 test i 0
# tail /var/log/snmptt/snmptt.log
※ 出力メッセージが書き足されていれば成功
