docker 部署单机 seata并且注册到nacos

下镜像

docker pull seataio/seata-server:1.4.2

配置宿主机文件挂载

mkdir /data/seata/seata-config

mkdir /data/seata/logs

seata 两个配置文件

seata-config文件夹下 registry.conf  （改nacos配置）

seata 配置放入nacos，建议config.txt 放在data/seata下，nacos-config.sh 放入data/seata/test

创建文件 config.txt

touch config.txt

创建文件 nacos-config.sh

touch nacos-config.sh

config.txt内容，改seata和nacos配置

给nacos推seata配置

sh nacos-config.sh -h 192.168.1.155 -p 8848 -g SEATA_GROUP  -u nacos -w nacos

启动seata ，注意，-e SEATA_IP=xx 一定要写成宿主机的ip，不然访问不到！！

docker run -it -d   -p 8091:8091 -p 7091:7091 \
-v /data/seata/seata-config/registry.conf:/seata-server/resources/registry.conf \
-v /data/seata/seata-config/file.conf:/seata-server/resources/file.conf \
-v /data/seata/logs:/root/logs \
-e SEATA_IP=192.168.1.155 \
--name seata1.4.2  seataio/seata-server:1.4.2
