- 啟動 lnms
ln -s /opt/librenms/lnms /usr/bin/lnms cp /opt/librenms/misc/lnms-completion.bash /etc/bash_completion.d/
- 設定 snmpd
cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf vi /etc/snmp/snmpd.conf --- 將 RANDOMSTRINGGOESHERE 改成自己的 snmp 密碼 com2sec readonly default RANDOMSTRINGGOESHERE : -- curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro chmod +x /usr/bin/distro systemctl enable snmpd systemctl restart snmpd
- 設定 crontab
cp /opt/librenms/librenms.nonroot.cron /etc/cron.d/librenms - 設定 logrotate
cp /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms - 開啟網頁進行設定 Exp. http://10.20.0.34
- 檢查設定
- 設定資料庫與匯入基本資料
- 建立管理者帳號密碼
- 如果有遇到問題可以執行以下語法進行檢測
sudo su - librenms ./validate.php
如果沒問題會顯示類似如下結果:
root@ct-librenms:/opt# sudo su - librenms librenms@ct-librenms:~$ ./validate.php ==================================== Component | Version --------- | ------- LibreNMS | 21.4.0-3-gcea6f13bf DB Schema | 2021_04_08_151101_add_foreign_keys_to_port_group_port_table (208) PHP | 7.4.3 Python | 3.8.5 MySQL | 10.3.25-MariaDB-0ubuntu0.20.04.1 RRDTool | 1.7.2 SNMP | NET-SNMP 5.8 ==================================== [OK] Composer Version: 2.0.12 [OK] Dependencies up-to-date.

設定自動找尋區域網路內可納管設備
- 假設區網為 192.168.1.0/24 (192.168.1.1 - 192.168.1.254)
- SNMP 都是設定為 v1 / v2c , Community 設定為 public 或 ichiayi_snmp
- 先安裝 python-ipaddress 模組 yum install python-ipaddress
- 先手動加入一個設備進行監管 Exp. 192.168.1.1
- vi /opt/librenms/config.php
: # Auto-Discovery // v1 or v2c $config['snmp']['community'][] = "public"; $config['snmp']['community'][] = "ichiayi_snmp"; $config['nets'][] = '192.168.1.0/24'; $config['autodiscovery']['nets-exclude'][] = '192.168.1.1/32'; $config['discovery_by_ip'] = true;
- 第一次可以手動執行一次
cd /opt/librenms ./snmp-scan.py
結果:
[root@ct-librenms librenms]# ./snmp-scan.py Scanning IPs: ..............................................................................................................................................................................................................................................++++++++++----- Scanned 253 IPs: 0 known devices, added 10 devices, failed to add 5 devices, 1 ips excluded by config Runtime: 104.31 seconds
- 設定 default_poller_group = 1
lnms config:set default_poller_group 1 - 之後在區域網路內的新設備如果有啟用 snmp v1 / v2c communty 符合設定的值, 可以在五分鐘內被自動加入
- 前一陣子發現設定都正確, 使用 snmp-scan.py 確實可以自動加入, 但卻無法如預期由該機制將新設備自動加入, 找了一些文章後還是無法真正解決問題, 目前我的 workaround 方法是將 snmp-scan.py 直接加入 cron 來處理
設定告警通知
- 設定 E-Mail 通知
- 設定告警通知規則
設定 Device Dependencies 設備依存關係
- Device Dependencies 可以減少不必要的告警通知, 例如 Firewall 故障, Firewall 內所有的主機當然無法使用, 此時可以設定裡面所有的主機的 Parents 是 Firewall 減少不必要的告警通知
- Exp. 192.168.1.254 是 Firewall, 192.168.1.222 是內部 Wifi 設備, 外部監控的 LibreNMS 可以設定 192.168.1.222 有個 Parents 是 192.168.1.254 可點下參考相關設定畫面

常見 LibreNMS 異常問題排除
每日自動更版失敗處理
- 先透過執行 daily.sh 看錯誤訊息
su - librenms ./daily.sh
- 看錯誤訊息進行處理, Exp. git 檔案被更改, 就移除這些檔案後, 在執行 daily.sh
- 如果無法解決, 可以透過 validate.php 來檢查
./vaildate.php: [FAIL] Some folders have incorrect file permissions, this may cause issues. [FIX]: sudo chown -R librenms:librenms /opt/librenms sudo setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/libr enms/bootstrap/cache/ /opt/librenms/storage/ sudo chmod -R ug=rwX /opt/librenms/rrd /opt/librenms/logs /opt/librenms/ bootstrap/cache/ /opt/librenms/storage/ Files: /opt/librenms/storage/framework/views/cdca770a337e07f2364ec770e7b408621 95170d7.php就依照內容說明去修正

- 其他實用的修復 script:
- 修復 git 目錄檔案 ./scripts/github-remove
- 自動更新失敗, 出現很多套件依存議題, Exp,. Carbon 1 is deprecated, see how to migrate to Carbon 2
- 可重新完整安裝的程序如下:
su - librenms ./scripts/github-remove -d -v git pull ./daily.sh ./validate.php
更新 python3
PHP 7.1 and Python 2 no longer supported LibreNMS will soon require Python 3.5+ and PHP 7.2.5+. For more details check https://t.libren.ms/uo84c 2020-05-11 00:00:00 | Source: http://www.librenms.org/notifications.rss
yum install python36
修改連線 DB
- 因為資料庫變大, 改用 Percona XtraDB Cluster 來取代本機 MySQL/MariaDB, 修改 /opt/librenms/config.php 內的 ### Database config 卻完全沒用, 看了 LibreNMS 文件才發現已經變成要改 /opt/librenms/.env 才對
- 以下是 /opt/librenms/.env 大概的內容
APP_KEY=base64:LvIYs6Gauexxxxxxxxxxxxxxxxxxxxxxxxxxxxxx5/c= DB_HOST=192.168.11.202 DB_DATABASE=librenms DB_USERNAME=**dbuser** DB_PASSWORD=**dbpasswd** #APP_URL= NODE_ID=5cxxxxxxxxxde DB_PORT=3306 LIBRENMS_USER=librenms
- 原本 mariadb 的設定要關閉
systemctl stop mariadb systemctl disable mariadb
CentOS 7 升級 php 至 7.4
- 2020/11/04 收到訊息會 2020/11 起, LibreNMS 必須使用 php 7.3 以上(建議 7.4)版本才會自動更新
- 先移除原本 PHP 7.2
systemctl stop php-fpm yum remove php72w* mv /etc/yum.repos.d/webtatic* /tmp/
- 將安裝 REMI 的 PHP 7.4 來因應
yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm vi /etc/yum.repos.d/remi-php74.repo
: [remi-php74] : enabled=1 :
yum install composer php php-cli php-common php-curl php-fpm php-gd php-mbstring php-mysqlnd php-process php-snmp php-xml php-zip
- 因為這方式是重新安裝 php 與相關套件, 所以 php.ini 與 nginx 的一些設定必須再次執行
- 修改 php.ini
vi /etc/php.ini: [Date] ; Defines the default timezone used by the date functions ; http://php.net/date.timezone date.timezone = Asia/Taipei :
- 修改 php-fpm 設定
vi /etc/php-fpm.d/www.conf: ;user = apache user = nginx : ;listen.owner = nobody ;listen.group = nobody ;listen.mode = 0660 listen.owner = nginx listen.group = nginx listen.mode = 0660 :
systemctl enable php-fpm systemctl restart php-fpm
- 修改 nginx 設定
vi /etc/nginx/conf.d/librenms.conf: : location ~ \.php { include fastcgi.conf; fastcgi_split_path_info ^(.+\.php)(/.+)$; #fastcgi_pass unix:/var/run/php-fpm/php7.2-fpm.sock; fastcgi_pass 127.0.0.1:9000; } :systemctl restart nginx - 設定 ping 的執行權限
setcap cap_net_raw+ep /usr/sbin/fping setcap cap_net_raw+ep /usr/sbin/fping6
- 驗證一下是否可以正常運作
su - librenms ./validate.php ./daily.sh
可能會出現一些 Call to undefined method … 訊息, 不過第二次執行 ./daily.sh 應該就不會再出現, 執行畫面如下
[root@ct-librenms ~]# su - librenms -bash-4.2$ ./validate.php ==================================== Component | Version --------- | ------- LibreNMS | 1.69-5-g240edd2 DB Schema | 2020_07_27_00522_alter_devices_snmp_algo_columns (188) PHP | 7.4.12 Python | 3.6.8 MySQL | 5.6.42-84.2-56-log RRDTool | 1.4.8 SNMP | NET-SNMP 5.7.2 OpenSSL | ==================================== [OK] Composer Version: 1.10.17 [OK] Dependencies up-to-date.

- 移轉 LibreNMS 程序可參考 https://docs.librenms.org/Support/FAQ/ 內
How do I move my LibreNMS install to another server?
CentOS 7 升級 MariaDB 10
- 2021/06/13 發現 Librenms 無法運作, 才發現 2021/03 起只支援 MySQL version 5.7.7 以上的版本, 所以目前使用的 Percona XtraDB Cluster 內的 5.6.42 就被迫要升級改用 MariaDB 10.5
- 將舊資料匯出, 如果忘記資料庫連線資訊, 可以看一下 .env
su - librenms head .env
Exp. db_host:192.168.11.21 , db_user:librenms , db_pass:Password , db_name:librenms
mysqldump -u librenms -p librenms -h 192.168.11.21> /tmp/librenms.sql - 在新資料庫建立 LibreNMS 的使用者與資料庫
mysql -u root -p create database librenms; create user 'librenms'@'%' identified by '**Password**'; grant all on librenms.* to 'librenms'@'%'; flush privileges; quit
- 將舊資料匯入新資料庫 Exp. 192.168.11.22
cat /tmp/librenms.sql | mysql -u librenms -p librenms -h 192.168.11.22 - 修改 .env 內 DB 的連線設定
su - librenms vi .env
./lnms migrate 出現 SQLSTATE[42S01] 異常
- 出現錯誤訊息如下

- 解決方式
mysql -u librenms -p librenms drop table port_groups;
- 再次執行 ./lnms migrate 出現找不到 librenms.port_group_port 這 table
In Connection.php line 678: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'librenms.port_group_port' doesn't exist (SQL: alter table `port_group_port` add constraint `port_group_port_port_group_id_for eign` foreign key (`port_group_id`) references `port_groups` (`id`) on delete CASCADE)
- 解決方式 :
mysql -u librenms -p librenms CREATE TABLE port_group_port ( port_group_id int(10) unsigned NOT NULL, port_id int(10) unsigned NOT NULL, PRIMARY KEY (port_group_id,port_id), KEY port_group_port_port_group_id_index (port_group_id), KEY port_group_port_port_id_index (port_id), CONSTRAINT port_group_port_port_group_id_foreign FOREIGN KEY (port_group_id) REFERENCES port_groups (id) ON DELETE CASCADE, CONSTRAINT port_group_port_port_id_foreign FOREIGN KEY (port_id) REFERENCES ports (port_id) ON DELETE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
- 再次執行 ./lnms migrate 就可以修正成功
- 再執行 ./validate.php 看有其他那些問題, 依照說明的語法進行修正 Exp.

- 在 Ubuntu 20.04 新主機將 librenms.sql 匯入
scp [email protected]:/root/librenms.sql . mysql -u root -p librenms < librenms.sql
- 將 CentOS 7 舊主機內的 rrd 目錄內的檔案複製到 Ubuntu 20.04 新主機內, @CentOs 7
cd /opt/librenms/ tar cvf rrd.tar rrd
@Ubuntu 20.04
cd /opt/librenms/ scp [email protected]:/opt/librenms/rrd.tar . tar xvf rrd.tar

升級 php 至 8.1 以上版本
- 今天看到這訊息
Error: PHP version too low
PHP version 8.1 is the minimum supported version as of September, 2022. We recommend you update to PHP a supported version of PHP (8.1 suggested) to continue to receive updates. If you do not update PHP, LibreNMS will continue to function but stop receiving bug fixes and updates.

- 更換 php-fpm 的版本設定
- 查看目前啟動的 php-fpm 狀況
