全网独家：zabbixV7版本容器服务器无法访问Postgres V17数据库的问题解决

article 2025/3/6 15:15:36

近期将zabbix平台从V6.2.6升级到7.2.4，遇到问题“PostgresoL server is not available. Waiting 5seconds”，容器无法访问Postgres V17数据库，本文记录问题解决过程。

一、系统环境

1、数据库版本

数据库版本：postgres-17.4-timescale-2.17.2，如下：

#  psql -U zabbix  zabbix -h 192.168.128.111  
Password for user zabbix: 
psql (13.3, server 17.4)
WARNING: psql major version 13, server major version 17.
         Some psql features might not work.
Type "help" for help.

zabbix=> \dx
                                                List of installed extensions
    Name     | Version |   Schema   |                                      Description                              
        
-------------+---------+------------+-------------------------------------------------------------------------------
--------
 plpgsql     | 1.0     | pg_catalog | PL/pgSQL procedural language
 timescaledb | 2.17.2  | public     | Enables scalable inserts and complex queries for time-series data (Community E
dition)
(2 rows)

zabbix=> \q

2、zabbix服务器容器版本

zabbix/zabbix-web-apache-pgsql:centos-7.2.4
zabbix/zabbix-server-pgsql:centos-7.2.4

二、报错信息

zabbix服务器连接数据库报错：“PostgresoL server is not available. Waiting 5seconds”

三、问题分析

1、数据库版本是否兼容

从zabbix官网，可以看到相关数据库版本在兼容清单的

support for PostgreSQL versions:- 17.X

support for TimescaleDB versions: 2.17.X

2、测试数据库外部连接情况

#  psql -U zabbix  zabbix -h 192.168.128.111  
Password for user zabbix: 
psql (13.3, server 17.4)
WARNING: psql major version 13, server major version 17.
         Some psql features might not work.
Type "help" for help.

zabbix=> \dx
                                                List of installed extensions
    Name     | Version |   Schema   |                                      Description                              
        
-------------+---------+------------+-------------------------------------------------------------------------------
--------
 plpgsql     | 1.0     | pg_catalog | PL/pgSQL procedural language
 timescaledb | 2.17.2  | public     | Enables scalable inserts and complex queries for time-series data (Community E
dition)
(2 rows)

zabbix=> \q

可以看到，数据库外部访问正常，可以查询到库的信息，可以排除数据库自身的问题。

3、问题定位

经过本人全面检查，最终查到本问题是因为zabbix服务器官方容器包的问题。

原因为zabbix使用--list来检查数据库服务是否存活，在容器外本地使用该命令，反馈信息如下：

# psql -U zabbix  zabbix -h 192.168.128.111 --list
Password for user zabbix: 
                             List of databases
   Name    |  Owner   | Encoding  | Collate | Ctype |   Access privileges   
-----------+----------+-----------+---------+-------+-----------------------
 postgres  | postgres | SQL_ASCII | C       | C     | 
 template0 | postgres | SQL_ASCII | C       | C     | =c/postgres          +
           |          |           |         |       | postgres=CTc/postgres
 template1 | postgres | SQL_ASCII | C       | C     | =c/postgres          +
           |          |           |         |       | postgres=CTc/postgres
 zabbix    | zabbix   | UTF8      | C       | C     | 
(4 rows)

登入zabbix服务器容器，可以看到容器内封装的PostgreSQL客户端版本为16.6，该命令执行反馈信息报错“column d.daticulocale does not exist”：

# docker exec -it zbxsrv /bin/bash
bash-5.1$ psql -V
psql (PostgreSQL) 16.6
bash-5.1$ psql -h 192.168.128.111 -U zabbix -d zabbix --list
Password for user zabbix: 
psql: ERROR:  column d.daticulocale does not exist
LINE 8:   d.daticulocale as "ICU Locale",
          ^
HINT:  Perhaps you meant to reference the column "d.datlocale".
bash-5.1$ cat /etc/centos-release 
CentOS Stream release 9

且zabbix官方Centos、ubuntu系统容器包都存在此问题。

四、解决办法

使用zabbix官方alpine系统平台的服务器容器镜像。

zabbix/zabbix-server-pgsql:alpine-7.2-latestalpine-7.2-latest（目前实际是7.2.4）

zabbix/zabbix-web-apache-pgsql:alpine-7.2.4

如下：

[root@localhost ~]# docker pull zabbix/zabbix-server-pgsql:alpine-7.2-latest

docker.io/zabbix/zabbix-web-apache-pgsql:alpine-7.2.4

运行容器，可以看到，服务器已正常连接：
