Ubuntu 20.04 install librenms
由於CentOS8 變成孤兒了，故著手把手頭的CentOS 上的版本做轉移
沒想到越做越越多問號，讓人不經懷疑網站上的編寫者有沒有實際自己跑過一遍XDDDD
由於花了不少時間解問題，就把筆記更新放著了
apt install software-properties-common
add-apt-repository universe
apt update
apt upgrade
官站上的教學
apt install acl curl composer fping git graphviz imagemagick mariadb-client mariadb-server mtr-tiny nginx-full nmap php7.4-cli php7.4-curl php7.4-fpm php7.4-gd php7.4-json php7.4-mbstring php7.4-mysql php7.4-snmp php7.4-xml php7.4-zip rrdtool snmp snmpd whois unzip python3-pymysql python3-dotenv python3-redis python3-setuptools
問題來了
在套件中 php預設會抓取認識php-curl而非 php7.4-curl
所以要裝 php-curl
建立帳戶
useradd librenms -d /opt/librenms -M -r -s "$(which bash)"
cd /opt
#恩 會出現錯誤 git gnutls_handshake() failed
git clone https://github.com/librenms/librenms.git
#查詢原因大致上是說明套件錯誤，但不管是停用改設定為Tls v1.2或是重包套件都沒過
#沒關係，山不轉路轉，改啟用ssl
1. 建立主機ssh-keygen
#ssh-keygen
2. cat ~/.ssh/id_rsa.pub
將公鑰複製下來大概長這樣
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQC9Kds9mB4tiT0wjP0DIwcs8ypdd7MhFv/V3uFsQ8Qxykw4jvxtcoRJX53DoaMWTlvCiywkE2x5XANivFVs/2cmRrP544aGadJ/oXMqClSegpdhthA9c2vt28ZtB28mB4fg9ci2gPIkBet74iruEjhbHGUcJ1Wzs8aCmvivHVaYiE6jtiZt48N8Xz6BfiVcIFmsvivnElh7bsZD13iXzM7Tq4PVKVPPMLLPqwjRj7lnR1jJD9P9IkUtikNLnXCDLBJ47X8vy8xA3QDMzBUFeNGCXeDnyfbpbN/YaGxydlsOTgBtu2HgkMVY4pPVUFxv/+dwiCM7hABDWUteuJrRO6FEAU1JhsDEJtGE6l5fwmx/zwOk5I0Wksg4vXu0ObcYUaBiK0vn5qHVTrm2iyq/4qGgeXF9b5ReHHJjv1X20yTQKPYSbfD3Pfqjno61xmQ/OSNPBm2K5py97SKA1888e/K8SJl5Sfpo9aMLq/S/01XtsVCSi2Kcv0= root@librenms
3. 登入git 帳號(沒有自己去建一個吧，很方便的)
Account settings到SSH and GPG keys選項>New SSH key>貼上
然後回到主機上
cd /opt
git clone git@github.com:librenms/librenms.git
會詢問是否接受，輸入yes點enter吧!
再來就回歸正途
設定資料夾權限
chown -R librenms:librenms /opt/librenms
chmod 771 /opt/librenms
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
#PHP pre-install
su - librenms
./scripts/composer_wrapper.php install --no-dev
exit
設定PHP Timezone
先確認自己的 timedatectl
Asia/Taipei
===
vi /etc/php/7.4/fpm/php.ini
vi /etc/php/7.4/cli/php.ini
===
變更主機時區(台北)
sudo timedatectl set-timezone Asia/Taipei
Configure MariaDB
#編輯設定
vi /etc/mysql/mariadb.conf.d/50-server.cnf
在[mysqld] 底下加入
innodb_file_per_table=1
lower_case_table_names=0
開啟並重啟服務
systemctl enable mariadb
systemctl restart mariadb
建立資料庫與設定 librenma帳密
CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_unicode_ci;
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost';
FLUSH PRIVILEGES;
exit
設定Configure PHP-FPM
cp /etc/php/7.4/fpm/pool.d/www.conf /etc/php/7.4/fpm/pool.d/librenms.conf
vi /etc/php/7.4/fpm/pool.d/librenms.conf
更改設定
將[www] 替換 [librenms]:
以下替換
user = librenms
group = librenms
listen = /run/php-fpm-librenms.sock
設定nginx
vi /etc/nginx/conf.d/librenms.conf
直接貼上
server {
listen 80;
server_name librenms.example.com;
root /opt/librenms/html;
index index.php;
charset utf-8;
gzip on;
gzip_types text/css application/javascript text/javascript application/x-javascript image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ [^/]\.php(/|$) {
fastcgi_pass unix:/run/php-fpm-librenms.sock;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi.conf;
}
location ~ /\.(?!well-known).* {
deny all;
}
}
移除預設設定與啟動
rm /etc/nginx/sites-enabled/default
systemctl restart nginx
systemctl restart php7.4-fpm
SELinux
Ubuntu 預設未啟用(Cen
Configure snmpd
cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf
cp /opt/librenms/librenms.nonroot.cron /etc/cron.d/librenms
cp /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms
