Seata configuration for direct connection blog

Seata Integration with Nacos Configuration blog

Let's go back to the basics of the previous posts to configure nacos as a configuration centre and dubbo registry.

Preparation

Install docker

yum -y install docker

Create the nacos and seata databases.

Pull the nacos and seata mirrors and run them.

docker run -d --name nacos -p 8848:8848 -e MODE=standalone -e MYSQL_MASTER_SERVICE_HOST=your mysql ip -e MYSQL_MASTER_SERVICE_DB_NAME=nacos -e MYSQL_MASTER_SERVICE_USER=root -e MYSQL_MASTER_SERVICE_PASSWORD=mysql password -e MYSQL_SLAVE_SERVICE_HOST=your mysql ip -e SPRING_DATASOURCE_PLATFORM=mysql PLATFORM=mysql -e MYSQL_DATABASE_NUM=1 nacos/nacos-server:latest

docker run -d --name seata -p 8091:8091 -e SEATA_IP=the ip you want to specify -e SEATA_PORT=8091 seataio/seata-server:1.4.2

Seata Configuration

Since there is no built-in vim in the seata container, we can directly cp the folder to the host and then cp it to go back.

docker cp container id:seata-server/resources The directory you want to place the folder in.

Get the ip addresses of the two containers using the following code

docker inspect --format='{{.NetworkSettings.IPAddress}}' ID/NAMES

After the configuration is complete, use the following command to copy the modified registry.conf to the container, and reboot to view the logs running

docker cp /home/seata/resources/registry.conf seata:seata-server/resources/
docker restart seata
docker logs -f seata

Run nacos-config.sh to import the Nacos configuration.

eg: sh ${SEATAPATH}/script/config-center/nacos/nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t 5a3c7d6c-f497-4d68-a71a-2e5e3340b3ca - u username -w password u username -w password

Refer to Configuration Import Instructions for specific parameter definitions.
