修改配置 \seata\script\config-center\config.txt

这里使用nacos+db的方式持久化,其他的可以删除.

上传config.txt到nacos

创建DB库

\seata\script\server\db

image.png

修改seata配置文件 \seata\conf\application.yml

这里配置的Nacos作用是读取刚刚上传到nacos的配置文件.配置两次重复是因为服务发现与配置中心可分开使用.

通过脚本启动seata \seata\bin\seata-server.sh

image.png

日志 \seata\log\start.out
这里启动脚本有一点报错,并不影响.

查看GUI http://127.0.0.1:7091 账号密码seata/seata

image.png

nacos也注册上了.

image.png

遇到问题:
1.脚本启动失败,报JVM参数异常, 解决方法: 检查JDK版本
2.seata注册到nacos的ip地址不对,导致RM无法绑定Seata. 解决方法:在seata脚本启动时添加-h标记ip地址.
