nacos适配达梦数据库

一、下载源码

        源码我直接下载gitee上nacos2.2.3的，具体链接：https://gitee.com/mirrors/Nacos/tree/2.2.3，具体如下图：

二、集成达梦数据库驱动

        解压源码包，用idea打开源码，等idea和maven编译完成，若是Jdk8的话，最好安装300以上的小版本。

        获取达梦数据库驱动，驱动包在安装目录的jdbc下，该驱动包是windows安装包里勾选了驱动，才会生成这些驱动。具体如下图所示：

        将驱动包复制到 nacos-config、nacos-naming 两个模块的resources/lib目录下，并添加依赖：

<dependency>
<groupId>com.dameng</groupId>
<artifactId>Dm8JdbcDriver18</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/lib/DmJdbcDriver18.jar</systemPath>
</dependency>

三、修改启动配置

        修改nacos-console模块的application.properties，具体如下：

其中，url参数详见链接：DM JDBC 编程指南 | 达梦技术文档

四、达梦数据库初始化SQL

        在达梦数据库运行下面SQL：

-- 创建用户

INSERT INTO nacos.roles (username, role) VALUES ('nacos', 'ROLE_ADMIN');
commit;

        这些sql可以放到distribution\conf\dm-schema.sql中，后续打包能看到该sql，如图：

五、新增达梦数据库Mapper文件

        将nacos-datasource-plugin里的mysql的mapper文件复制到新的dm文件夹下改名，并修改将相应的常量和配置，具体如下：

六、启动Nacos

        找到 com.alibaba.nacos.Nacos类，启动即可，或者加入 -Dnacos.standalone=true 参数单机启动，集群启动需要在 用户文件夹下的 nacos/conf 下放置 cluster.conf 文件。

        另外注意nacos的url一定不能写错，否则报：Caused by: java.lang.IllegalStateException: No DataSource set

七、打包并运行Nacos

        配置环境变量，MAVEN_HOME和JAVA_HOME，以及在Path中添加bin路径。具体如下：

        接着到nacos项目路径下运行：

mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U

或者：mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U  -Dcheckstyle.skip

成功后，nacos包会在 Nacos-2.2.3\distribution\target 目录下：

        将新打包的nacos-server-2.2.3.zip复制解压，如下图：

        到nacos/conf目录下修改 application.properties，具体参考源码的配置文件。

        在nacos/bin目录下cmd运行：startup.cmd -m standalone。
