1.Seata+Nacos deployment

Script description

client

Address: https://github.com/seata/seata/tree/develop/script/client

Store the configuration and SQL for the client

• At: undo in at mode_ Log table creation statement
• conf: configuration file of the client
• Saga: table creation statement of the required table in Saga mode
• Spring: configuration file supported by springboot application

server

Address: https://github.com/seata/seata/tree/develop/script/server

Store the SQL and deployment scripts required on the server side

• db: the table creation statement of the table required when the save mode on the server side is db
• Docker compose: script deployed through docker compose on the server side
• Helm: script deployed through helm on the server side
• Kubernetes: script deployed through kubernetes on the server side

config-center

Address: https://github.com/seata/seata/tree/develop/script/config-center

It is used to store the initialization scripts of various configuration centers. Config. Is read during execution Txt configuration file and write it to the configuration center

• Nacos: used to add configuration to Nacos
• zk: used to add configuration to ZooKeeper. The script depends on the relevant scripts of ZooKeeper and needs to be downloaded manually; ZooKeeper related configurations can be written in zk params Txt, which can also be entered during execution
• Apollo: add configuration to Apollo. The address and port of Apollo can be written in Apollo params Txt, which can also be entered during execution
• Etcd3: used to add configuration to etcd3
• Consumer: used to add configuration to consumer

1.Nacos registry + Nacos configuration center + DB storage

Using nacos as the configuration, the registry realizes cluster high availability

1.1 config.txt writing

Specify store Mode = file | DB | redis mainly modifies mysql connection or redis connection configuration

**File path: / home / service / Seata / config Txt * * tips: after uploading to nacos, you can modify the configuration on nacos
