Initialize nacos configuration of seata

conf directory execution:

sh nacos-config.sh 47.112.217.177

Note: if your Nacos port is not the default 8848 port, you need to change nacos-config.sh

My nacos is a cluster, so I changed the default port. nacos cluster construction: https://my.oschina.net/u/1046143/blog/3217779

result=`curl -X POST "http://$nacosIp:8847/nacos/v1/cs/configs?dataId=$key&group=SEATA_GROUP&content=$value"`

Log in to nacos background after execution:

Start the sea TA server service

[root@iZwz9e2l6djknfngtgxfbnZ conf]# cd ../bin/
[root@iZwz9e2l6djknfngtgxfbnZ bin]# ls
seata-server.bat  seata-server.sh

Execute:. / seata-server.sh
