SQL ：https://github.com/apache/incubator-seata/blob/2.0.0/script/server/db/mysql.sql
1.4 seata 对应Nacos 配置 seata-server.properties

}2、获取配置信息
2.1 创建配置文件目录
[root@Tseng ~]# mkdir -p /data/seata/config
[root@Tseng ~]#2.2 启动临时容器
[root@Tseng ~]# cd /data/seata/config
[root@Tseng config]# docker run --name seata-server -d --rm -p 8091:8091 -p 7091:7091 seataio/seata-server:2.0.0
d46962d31951b64922ceb97af465f054f0dde49d317f73beacc6492c3af1bbe6
[root@Tseng config]#2.3 将容器内默认配置文件复制出来
[root@Tseng config]# docker cp seata-server:/seata-server/resources /data/seata/config
[root@Tseng config]# ls
resources
[root@Tseng config]#2.4 停止容器，删除默认配置文件，建立新的配置文件
[root@Tseng config]# docker stop d469
d469
[root@Tseng config]# cd resources/
[root@Tseng resources]# ls
application.example.yml application.raft.example.yml application.yml banner.txt docker io logback logback-spring.xml lua META-INF README.md README-zh.md
[root@Tseng resources]# rm -rf application.yml
# 1.2 步骤中的配置文件信息
[root@Tseng resources]# vim application.yml
[root@Tseng resources]# cat application.yml
