zabbix1.6のmysqlデータベースをzabbix1.8にマイグレーションする

パッチ適用の準備

下記を実行とあります。

alter table dhosts drop index dhosts_1;
alter table dservices drop index dservices_1;
alter table httptest drop index httptest_2;
alter table httptest drop index httptest_3;
alter table history_log drop index history_log_2;
alter table history_text drop index history_text_2;
alter table actions drop index actions_1;
alter table escalations drop index escalations_2;
alter table graphs_items drop index graphs_items_1;
alter table graphs_items drop index graphs_items_2;
alter table services drop index services_1;

バージョンが微妙に違うのか幾つかエラーが出ます。

パッチ適用

エラーは、出ましたが、そのままパッチを当ててみました。

$ zcat /usr/share/doc/zabbix-server-mysql/examples/patch.sql.gz | mysql -u root -p zabbix
Enter password:

zabbixサーバの起動

サーバを起動してブラウザでアクセスするとエラーはなくなり過去データも残っていました。
グラフの日本語が文字化けしているようです。
これで、しばらく様子を見ます。

$ sudo /etc/init.d/zabbix-server start
* Starting Zabbix server zabbix_server
...done.
