SpringCloud Alibaba - Basic environment preparation

instructions

The environment used is run using docker container, with docker-compose orchestration.
In the early stage, we will focus on the integration demonstration. All containers are run on a single machine. Later, we will explain how to build an HA cluster environment.

Local Environment Configuration

The operating system	Run a memory	Number of CPU core	Docker version
Mac OS 11	32 GB	Six nuclear	20.10.5

Environment set up

The containers created here are: Nacos 2.0.0, MySql 8.0.16, Sentinel Dashboard 1.8.0, Seata 1.4.1.

Redis, Mongo, RocketMQ, ES, and so on, we’ll get to that later.

Note: Here our Seata configuration is directly integrated into Nacos

The configuration file

docker-compose

Docker-comemage. yml is configured as follows

version: "3"

  ali-nacos:

Copy the code

The directory structure

Start the container

Enter the directory created by the YML file and run the startup command

Create a netgroup
docker network create cloud_alibaba

# run
docker-compose -f docker-compose-cloud-ali.yaml up -d
Copy the code

After the startup is complete, connect to mysql

Go to the config-center/nacos directory and run sh to upload the seATA configuration to nacOS

cdConfig-center /nacos sh./nacos-config.sh -h 127.0.0.1 -p 8848 -g SEATA_GROUP -u nacos -w nacosSh -h nacos address -p nacos port -g Group -u nacos user name -w nacos password
Copy the code

If Init nacOS config finished is displayed, please start seta-server. That’s it.

Then create a database seatA_config and execute the following statement to create three tables of the seATA global transaction

The password of user root of mysql is codelong

nacos

The browser input: http://127.0.0.1:8848/nacos

The username and password are both nacos

Nacos is successfully started.

sentinel

Enter http://127.0.0.1:8858/ in the browser

The username and password are both sentinel

Sentinel is successfully started.

seata

Enter the NACOS console to view the service list. If seATa-Server is displayed, seATA is successfully registered.

mysql

The username and password are both nacos

You can also log in as user root

To this basic environment has been built, the specific configuration we will explain one by one in the integration.
