NGUYÊN NHÂN

Lỗi này thường gặp kết nối với Database sau khi tải xong Zabbix. Nguyên nhân là Zabbix chỉ sử dụng các character khuyến nghị như UTF8, UTF8MB3

mysql Ver 14.14 Distrib 5.7.43, for Linux (x86_64) zabbix_server (Zabbix) 4.0.47 PHP 5.4.16

GIẢI PHÁP

Chuyển đổi character

MYSQL>SET @ZABBIX_DATABASE = 'database name>';

MYSQL>alter database <database name> character SET utf8 COLLATE utf8_bin;

Kiểm tra character của database

MYSQL>select default_character_set_name from information_schema.SCHEMATA S WHERE schema_name ="<database name>";

Do lúc tạo các table cũng đã ăn với character khác. Cần đổi tất cả table.

script utf8_convert.sql (script chuyển đổi character tất cả table )

Chạy lệnh sau:

#$ mysql -u root -p <database name> < utf8_convert.sql

Nội dung script utf8_convert.sql ( mọi người tạo file rồi copy đoạn bên dưới vào và sửa lại database name nhé )
