RuoYi-Cloud 进阶篇_03（ Seata 高可用集群与 NacosConfig配置中心整合）

文章目录

1. 创建文件config.txt
2. 创建nacos-config.sh
3. 配置导入nacos配置中心
4. 配置验证

1. 创建文件config.txt

在seata的安装文件夹下创建文件config.txt

[root@node2 ~]# cd /app/seata/seata-server-1.4.2/
[root@node2 seata-server-1.4.2]# vim config.txt

说明：
第一行：这里order-service值得是订单模块的服务
从第二行开始：下面是数据库信息根据自己的实际情况配置
注意点：不能添加中文注释

添加以下内容：

service.vgroupMapping.order-service=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/ry-seata?useUnicode=true
store.db.user=root
store.db.password=123456
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

上面的文件是精简后的部分，完整文件可在github中找到

https://github.com/seata/seata/blob/develop/script/config-center/config.txt

2. 创建nacos-config.sh

在conf/文件夹下下载文件
https://github.com/seata/seata/blob/develop/script/config-center/nacos/nacos-config.sh
用于将上面的seata配置信息导入到nacos 执行下面的命令

[root@node2 seata-server-1.4.2]# cd conf
[root@node2 conf]# vim nacos-config.sh
内容比较多，建议直接下载吧

echo "========================================================================="if [ ${failCount} -eq 0 ]; thenecho " Init nacos config finished, please start seata-server. "
elseecho " init nacos config fail. "
fi

3. 配置导入nacos配置中心

将seata配置信息导入到nacos config配置中心

 sh nacos-config.sh -h 127.0.0.1

-h后面是nacos配置中心的地址
操作记录：

[root@node2 conf]#  sh nacos-config.sh -h 127.0.0.1
set nacosAddr=127.0.0.1:8848
set group=SEATA_GROUP
Set service.vgroupMapping.order-service=default successfully
Set store.mode=db successfully
Set store.db.datasource=druid successfully
Set store.db.dbType=mysql successfully
Set store.db.driverClassName=com.mysql.cj.jdbc.Driver successfully
Set store.db.url=jdbc:mysql://127.0.0.1:3306/ry-seata?useUnicode=true successfully
Set store.db.user=root successfully
Set store.db.password=123456 successfully
Set store.db.minConn=5 successfully
Set store.db.maxConn=30 successfully
Set store.db.globalTable=global_table successfully
Set store.db.branchTable=branch_table successfully
Set store.db.queryLimit=100 successfully
Set store.db.lockTable=lock_table successfully
Set store.db.maxWait=5000 successfully
=========================================================================Complete initialization parameters,  total-count:15 ,  failure-count:0
=========================================================================Init nacos config finished, please start seata-server.
[root@node2 conf]#

4. 配置验证

执行完成后登录到nacos 查看配置中心的数据是否导入完毕，如图所示
