自Zabbix 6.0起,主键会应用于新安装 Zabbix 数据库的所有表。
在这之前安装过的Zabbix,本章节将提供手动升级所有表主键的说明。
此章节适用于如下数据库:
此页面上提供的说明专为高级用户设计。请注意,这些说明可能需要根据您的特定配置进行调整。
导出和导入必须在 tmux/screen 中执行,以确保会话不会被丢弃。
另请参阅:重要说明
此方法可用于正在运行的 Zabbix server,但建议在升级时停止server。 MySQL Shell (mysqlsh) 必须 已安装 并且能够连接到数据库。
以 root(推荐)或任何具有 FILE 权限的用户身份登录 MySQL 控制台。
启用 local_infile 变量启动 MySQL。
通过运行 history_pk_prepare.sql
重命名旧表并创建新表。
mysql -uzabbix -p<password> zabbix < /usr/share/zabbix-sql-scripts/mysql/history_pk_prepare.sql
通过 mysqlsh 连接。 如果使用套接字连接,可能需要指定路径。
· sudo mysqlsh -uroot -S /run/mysqld/mysqld.sock --no-password -Dzabbix
运行(CSVPATH可根据需要更改):
CSVPATH="/var/lib/mysql-files";
util.exportTable("history_old", CSVPATH + "/history.csv", { dialect: "csv" });
util.importTable(CSVPATH + "/history.csv", {"dialect": "csv", "table": "history" });
util.exportTable("history_uint_old", CSVPATH + "/history_uint.csv", { dialect: "csv" });
util.importTable(CSVPATH + "/history_uint.csv", {"dialect": "csv", "table": "history_uint" });
util.exportTable("history_str_old", CSVPATH + "/history_str.csv", { dialect: "csv" });
util.importTable(CSVPATH + "/history_str.csv", {"dialect": "csv", "table": "history_str" });
util.exportTable("history_log_old", CSVPATH + "/history_log.csv", { dialect: "csv" });
util.importTable(CSVPATH + "/history_log.csv", {"dialect": "csv", "table": "history_log" });
util.exportTable("history_text_old", CSVPATH + "/history_text.csv", { dialect: "csv" });
util.importTable(CSVPATH + "/history_text.csv", {"dialect": "csv", "table": "history_text" });
这种升级方法需要更多时间,只有在无法使用 mysqlsh 进行升级时才应使用。
以 root(推荐)或任何具有 FILE 权限的用户身份登录 MySQL 控制台。
启用 local_infile 变量启动 MySQL。
通过运行 history_upgrade_prepare.sql
重命名旧表并创建新表:
mysql -uzabbix -p<password> zabbix < /usr/share/zabbix-sql-scripts/mysql/option-patches/history_upgrade_prepare.sql
max_execution_time 必须在迁移数据之前禁用以避免迁移期间超时。
SET @@max_execution_time=0;
INSERT IGNORE INTO history SELECT * FROM history_old;
INSERT IGNORE INTO history_uint SELECT * FROM history_uint_old;
INSERT IGNORE INTO history_str SELECT * FROM history_str_old;
INSERT IGNORE INTO history_log SELECT * FROM history_log_old;
INSERT IGNORE INTO history_text SELECT * FROM history_text_old;
按照迁移后说明删除旧表。
检查启用了哪些路径导入/导出:
mysql> SELECT @@secure_file_priv;
+-----------------------+
| @@secure_file_priv · |
+-----------------------+
| /var/lib/mysql-files/ |
+-----------------------+
如果 secure_file_priv 值是目录路径,则将对该目录中的文件执行导出/导入。 在这种情况下,相应地编辑查询中文件的路径或将secure_file_priv 值设置为升级时间的空字符串。
如果 secure_file_priv 值为空,则可以从任何位置执行导出/导入。
如果 secure_file_priv 值为 NULL,将其设置为包含导出表数据的路径(上例中的“/var/lib/mysql-files/”)。
有关详细信息,请参阅 MySQL 文档。
max_execution_time 必须在导出数据之前禁用以避免导出期间超时。

按照 迁移后说明 删除旧表。
导出和导入必须在 tmux/screen 中执行,以确保会话不会被丢弃。 对于使用 TimescaleDB 的安装,请跳过此部分并继续阅读 PostgreSQL + TimescaleDB。

history_pk_prepare.sql
重命名表。cd /usr/share/zabbix/zabbix-sql-scripts/database/oracle
sqlplus zabbix/password@oracle_host/service
sqlplus> @history_pk_prepare.sql
####历史表批量迁移
Data Pump 必须对这些目录具有读写权限。
例子:
expdp zabbix/password@oracle_host/service \
· DIRECTORY=history \
· TABLES=history_old,history_uint_old,history_str_old,history_log_old,history_text_old \
· PARALLEL=N
impdp zabbix/password@oracle_host/service \
· DIRECTORY=history \
· TABLES=history_uint_old \
REMAP_TABLE=history_old:history,history_uint_old:history_uint,history_str_old:history_str,history_log_old:history_log,history_text_old:history_text \
· data_options=SKIP_CONSTRAINT_ERRORS table_exists_action=APPEND · PARALLEL=N CONTENT=data_only
####历史表的单独迁移
例子:
mkdir -pv /export/history /export/history_uint /export/history_str /export/history_log /export/history_text
chown -R oracle:oracle /导出
create directory history as '/export/history';
grant read,write on directory history to zabbix;
create directory history_uint as '/export/history_uint';
grant read,write on directory history_uint to zabbix;
create directory history_str as '/export/history_str';
grant read,write on directory history_str to zabbix;
create directory history_log as '/export/history_log';
grant read,write on directory history_log to zabbix;

对于所有数据库,迁移完成后,执行以下操作:
验证一切是否按预期工作。
删除旧表:
DROP TABLE history_old;
DROP TABLE history_uint_old;
DROP TABLE history_str_old;
DROP TABLE history_log_old;
DROP TABLE history_text_old;
