備妥 LAPP (Liunx Apache PostgreSQL PHP) 或
LAMP (Liunx Apache MYSQL PHP) ....的運行環境
我的安裝順序 Liunx Apache Mysql (MariadDB) PHP ,
因為之前已測試過 LibreNMS 在 Oracle 9 的運行環境.
故這次僅需加裝上PostgreSQL即可.在安裝之前先看了一下 release_notes 資訊,
進而得知它支援 TimescaleDB 2.13 與 PostgreSQL 16 ,
之前都是亂裝一通導致 Zabbix 裝不起來的情事.GG
所以先行將 PostgreSQL 16 + TimescaleDB 2.13 的組合先行安裝.
https://www.zabbix.com/release_notes
==> Updated max supported TimescaleDB version to 2.13 Server
==> Increased PostgreSQL maximum supported version to 16
PostgreSQL 16 可參考如下 URL
https://www.postgresql.org/download/
因為我是使用 Oracle Linux 所以是看這個.
https://www.postgresql.org/download/linux/redhat/
安裝操作依官網 SOP 即可...
# Install the repository RPM:
sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-9-x86_64/pgdg-redhat-repo-latest.noarch.rpm
# Disable the built-in PostgreSQL module:
sudo dnf -qy module disable postgresql
# Install PostgreSQL:
sudo dnf install -y postgresql16-server
# Optionally initialize the database and enable automatic start:
sudo /usr/pgsql-16/bin/postgresql-16-setup initdb
sudo systemctl enable postgresql-16
sudo systemctl start postgresql-16
PostgreSQL安裝完成後,重要的設定及安裝程式會放置在這二處
[root@Oracle9 pgsql-16]# pwd
/usr/pgsql-16
[root@Oracle9 16]# pwd
/var/lib/pgsql/16
為方便後續的操作及使用
vi /etc/profile
最下方處加上如下設定.
PATH=$PATH:/usr/pgsql-16/bin/
export PATH
PGDATA=/var/lib/pgsql/16/data
export PGDATA
及做一些必要的 postgresql 服務設定.
vi /var/lib/pgsql/16/data/pg_hba.conf
vi /var/lib/pgsql/16/data/postgresql.conf
===============================================
TimescaleDB 可參考如下 URL
https://packagecloud.io/timescale/timescaledb/install
因為我是要下載及安裝指定版本,故我選擇用手動下載及安裝的方式進行之.
TimescaleDB 2.13 可參考如下 URL

TimescaleDB has been installed. You need to update your postgresql.conf file
to load the library by adding 'timescaledb' to your shared_preload_libraries.
The easiest way to do this (and more configuration) is to use timescaledb-tune:
timescaledb-tune --pg-config=/usr/pgsql-16/bin/pg_config
依指示做 timescaledb-tune
[root@Oracle9 timescaledb-2-pg16]# timescaledb-tune --pg-config=/usr/pgsql-16/bin/pg_config
Using postgresql.conf at this path:
/var/lib/pgsql/16/data/postgresql.conf
Is this correct? [(y)es/(n)o]: y
Writing backup to:
/tmp/timescaledb_tune.backup202406091011
shared_preload_libraries needs to be updated
Current:
#shared_preload_libraries = ''
Recommended:
shared_preload_libraries = 'timescaledb'
Is this okay? [(y)es/(n)o]: y
success: shared_preload_libraries will be updated
Tune memory/parallelism/WAL and other settings? [(y)es/(n)o]: y

effective_cache_size = 5614MB
maintenance_work_mem = 958185kB
work_mem = 4790kB

success: memory settings will be updated
Parallelism settings recommendations
Current:
missing: timescaledb.max_background_workers
#max_worker_processes = 8

max_worker_processes = 23
max_parallel_workers_per_gather = 2
max_parallel_workers = 4
Is this okay? [(y)es/(s)kip/(q)uit]: y

WAL settings recommendations
Current:
#wal_buffers = -1
min_wal_size = 80MB
Recommended:
wal_buffers = 16MB
min_wal_size = 512MB
