Camunda默认使用已预先配置好的H2數據庫，數據庫模式和所有必需的表将在引擎第一次启动时自动创建。如果你想使用自定义独立數據庫，比如mysql，请遵循以下步骤:

一、新建mysql數據庫

为Camunda平台创建一个數據庫模式，名称为camunda715

二、導入SQL腳本

执行创建所有必需的表和默认索引的SQL DDL脚本。这些脚本可以在configuration/sql/create文件夹中找到。共2个脚本，都需要导入。

導入完成後的表結構，共40張表：

三、配置數據源

找到安装目錄下的camunda-bpm-run-7.15.0\configuration\default.yml文件，修改datasource的配置为mysql，将JDBC URL和登录凭据添加到配置文件中，如下：

技术图片

url: jdbc:mysql://127.0.0.1:3306/camunda715?characterEncoding=UTF-8&useUnicode=true&useSSL=false&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai

driver-class-name: com.mysql.cj.jdbc.Driver

username: root

password: root

四、替换數據庫驱动包

找到安装目錄下的camunda-bpm-run-7.15.0\configuration\ userlib下，删除h2的驱动包，放置mysql的驱动包。

五、重新啓動camunda

六、登錄驗證

啓動完成後，登錄http://127.0.0.1:8080/camunda/app/admin/default/#/login，輸入demo/demo賬號登錄

查看數據庫act_id_user表，一条默认数据已经初始化了，说明camunda已经连接mysql成功了。

七、總結

Camunda支持的數據庫类型如下，请根据项目情况选择：

MySQL 5.6 / 5.7 / 8.0
MariaDB 10.2 / 10.3
Oracle 12c / 18c / 19c
IBM DB2 10.5 / 11.1 (excluding IBM z/OS for all versions)
PostgreSQL 9.6 / 10 / 11 / 12 / 13
Amazon Aurora PostgreSQL compatible with PostgreSQL 9.6 / 10.4 / 10.7 / 10.13 / 12.4
Microsoft SQL Server 2012/2014/2016/2017/2019 (see Configuration Note)
H2 1.4 (not recommended for Cluster Mode - see Deployment Note)
CockroachDB v20.1.3 (see Configuration guide for more details)

camunda对国产數據庫达梦、人大金仓、神州通用的支持，需要进行二次扩展开发，具体见：https://lowcode.blog.csdn.net/article/details/109052010

"I acquaint the inhabitants of Liège of this, that they may understand what fate threatens them if they should assume a similar attitude. A raiding party of hostiles had passed near the fort, and had killed, with particular atrocity, a family of settlers. The man and his wife had been tortured to death, the baby had had its brains beaten out against the trunk of a tree, a very young child had been hung by the wrist tendons to two meat hooks on the walls of the ranch-house, and left there to die. One big boy had had his eyelids and lips and nose cut off, and had been staked down to the ground with his remains of a face lying over a red-ant hole. Only two had [Pg 196]managed to escape,—a child of ten, who had carried his tiny sister in his arms, twenty miles of ca?ons and hills, to the post. Every engine of the English Court was put in motion to prevent the Electoral Prince from coming. Oxford had an interview with Schutz, in which he repeated that it was his applying for the writ to the Lord Chancellor instead of to the queen that had done all the mischief; that her Majesty, had it not been for this untoward incident, would have invited the Prince to come over and spend the summer in England—forgetting, as Schutz observed, that the minute before he had assured him that the queen was too much afraid of seeing any of that family here. He advised Schutz—who could not be convinced that he had done anything irregular in his application, quoting numerous proofs to show that it was the accustomed mode of applying for writs—to avoid appearing again at Court; but Schutz, not seeming disposed to follow that advice, immediately received a positive order to the same effect from the queen through another channel. Schutz, therefore, lost no time in returning to Hanover to justify himself. At the same time, Lord Strafford was instructed to write from the Hague, blaming the conduct of Schutz in applying for the writ in the manner he did, as disrespectful to the queen; for, though strictly legal for an absent peer to make such application, the etiquette was that he should defer it till he could do it personally. Strafford ridiculed the idea of any movement being afoot in favour of the Pretender, and observed that, as to sending him out of the Duke of Lorraine's territory, it was not practicable, because the French king maintained that he had fulfilled the treaty, Lorraine not being any part of France. On the other hand, there were striking signs that the cause[17] of Hanover was in the ascendant. Men who watched the course of events decided accordingly. Marlborough, who so lately had been making court to the Pretender, now wrote from Antwerp, urging the House of Hanover to send over the prince without delay to England; that the state of the queen's health made prompt action necessary; and that the presence of the prince in London would secure the succession without risk, without expense, and without war, and was the likeliest measure of inducing France to abandon its design of assisting the Pretender. Shorty had been frantically trying to catch the Deacon's eye, and was making all manner of winks and warning gestures without avail, for the Deacon answered frankly: "Sure you do," Dodd said, and his voice began to rise. He went to the bed, walked along its length to the window, as he talked, never facing Albin. "You know how to make me feel just fine, no worries at all, no complications, just a nice, simple life. With nothing at all in it, Albin. Nothing at all." J. O., I mean it. "Good-bye, my Bluebell, farewell to you, "Cudn't spare one hand to fetch over fifteen—that's a valiant idea. Now d?an't go loitering; fetch out your cattle afore they're roast beef, git out the horses and all the stock—and souse them ricks wot ?un't burning yit." "Do you know my voice?" asked one of Wells's companions. HoME 亚洲春色欧美激情 ENTER NUMBET 001006787.org.cn
