Zabbix 7.0 LTS 版本試裝

 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 

https://packagecloud.io/timescale/timescaledb

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

Recommendations based on 7.31 GB of available memory and 4 CPUs for PostgreSQL 16


Memory settings recommendations

Current:

shared_buffers = 128MB

#effective_cache_size = 4GB

#maintenance_work_mem = 64MB

#work_mem = 4MB

Recommended:

shared_buffers = 1871MB

effective_cache_size = 5614MB

maintenance_work_mem = 958185kB

work_mem = 4790kB

Is this okay? [(y)es/(s)kip/(q)uit]: y

success: memory settings will be updated


Parallelism settings recommendations

Current:

missing: timescaledb.max_background_workers

#max_worker_processes = 8

#max_parallel_workers_per_gather = 2

#max_parallel_workers = 8

Recommended:

timescaledb.max_background_workers = 16

max_worker_processes = 23

max_parallel_workers_per_gather = 2

max_parallel_workers = 4

Is this okay? [(y)es/(s)kip/(q)uit]: y

success: parallelism settings will be updated


WAL settings recommendations

Current:

#wal_buffers = -1

min_wal_size = 80MB

Recommended:

wal_buffers = 16MB

min_wal_size = 512MB

Is this okay? [(y)es/(s)kip/(q)uit]: y

success: WAL settings will be updated


Background writer settings recommendations

Current:

Recommended:

Is this okay? [(y)es/(s)kip/(q)uit]: y

success: background writer settings will be updated


Miscellaneous settings recommendations

Current:

#default_statistics_target = 100

#random_page_cost = 4.0

#checkpoint_completion_target = 0.9

#max_locks_per_transaction = 64

#autovacuum_max_workers = 3

#autovacuum_naptime = 1min

#effective_io_concurrency = 1

Recommended:

default_statistics_target = 100

random_page_cost = 1.1

checkpoint_completion_target = 0.9

max_locks_per_transaction = 64

autovacuum_max_workers = 10

autovacuum_naptime = 10

effective_io_concurrency = 256

Is this okay? [(y)es/(s)kip/(q)uit]: y

success: miscellaneous settings will be updated
