首先介绍下seata的坑： is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying) No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-netflix-ribbon? 由于SpringCloud Feign在Hoxton.M2 RELEASED版本之后不再使用Ribbon而是使用spring-cloud-loadbalancer，所以不引入spring-cloud-loadbalancer会报错
如果使用openfegin
seata1.3.0中 can not register RM,err:can not connect to services-server. ：解决方式要把内网IP换成外网IP #启动sentinel的时候 指定端口 ip这个内网IP问题自然迎刃而解 #-p：Seata TC Server 监听的端口； #-h：指定ip #-n：Server node，在多个 TC Server 时，需区分各自节点，用于生成不同区间的 transactionId 事务编号，以免冲突； ./seata-server.sh -p 18091 -h 47.110.237.194 -n 1
在介绍下脚本nacos-config.sh.sh的内容：里面的port ip group username和password可以指定
脚本在github路径:

" else echo " init nacos config fail. " fi
再介绍下ncaso的配置文件config.txt：可以根据自己的需要更改存储类型db和分组信息
配置在gitHub的路径：

接下来介绍脚本nacos-config.sh.sh和seata配置config.txt的使用： 把脚本和配置复制到server目录下，如下图所示 命令也如下图所示 出现XXXXXx successfully时表示已经把配置config.tx里面的内容同步到nacos里面去了
上图的SEATA_GROUP和服务端的 registry.conf 里面保持一致 group = "SEATA_GROUP"
以下是我个人seata1.3.0在项目消费方和服务者间的配置：
消费者：
服务者：
seata服务端注册到ncaos配置：
