配置 Debezium 以连接到给定的 mySQL 实例

Question

假设我将获得多个 MySQL 实例并且必须流式传输实时数据。因此，为此，我使用以下列出的命令在 Docker Container 上启动了一些服务，这些命令将我连接到示例库存数据库，并且当我在 MySQL 命令行客户端中执行任何 DML 命令时，能够监控这些数据更改。

但是连接到实际 MySQL 数据库并在观察者窗口中流式传输相同的内容需要哪些更改或等效命令。

docker run -it --rm --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 debezium/zookeeper:1.1

docker run -it --rm --name kafka -p 9092:9092 --link zookeeper:zookeeper debezium/kafka:1.1

docker run -it --rm --name mysql -p 3308:3308 -e MYSQL_ROOT_PASSWORD=debezium -e MYSQL_USER=mysqluser -e MYSQL_PASSWORD=mysqlpw debezium/example-mysql:1.1

docker run -it --rm --name mysqlterm --link mysql --rm mysql:5.7 sh -c "exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"debezium""

docker run -it --rm --name connect -p 8083:8083 -e GROUP_ID=1 -e CONFIG_STORAGE_TOPIC=my_connect_configs -e OFFSET_STORAGE_TOPIC=my_connect_offsets -e STATUS_STORAGE_TOPIC=my_connect_statuses --link zookeeper:zookeeper --link kafka:kafka --link mysql:mysql debezium/connect:1.1

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/ -d "{ \"name\": \"inventory-connector\", \"config\": { \"connector.class\": \"io.debezium.connector.mysql.MySqlConnector\", \"tasks.max\": \"1\", \"database.hostname\": \"mysql\", \"database.port\": \"3306\", \"database.user\": \"debezium\", \"database.password\": \"dbz\", \"database.server.id\": \"184054\", \"database.server.name\": \"dbserver1\", \"database.whitelist\": \"inventory\", \"database.history.kafka.bootstrap.servers\": \"kafka:9092\", \"database.history.kafka.topic\": \"dbhistory.inventory\" } }"

docker run -it --rm --name watcher --link zookeeper:zookeeper --link kafka:kafka debezium/kafka:1.1 watch-topic -a -k dbserver1.inventory.customers

假设 MySQL 连接细节如下：

Host address of MySQL : XXX.XXX.X.XXX
Databse/Schema : YYYYY
Username : ZZZZZ
Password : PPPPP
port : 3306

任何线索/解释将不胜感激！

当您使用此配置连接器时

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/ -d "{ \"name\": \"inventory-connector\", \"config\": { \"connector.class\": \"io.debezium.connector.mysql.MySqlConnector\", \"tasks.max\": \"1\", \"database.hostname\": \"mysql\", \"database.port\": \"3306\", \"database.user\": \"debezium\", \"database.password\": \"dbz\", \"database.server.id\": \"184054\", \"database.server.name\": \"dbserver1\", \"database.whitelist\": \"inventory\", \"database.history.kafka.bootstrap.servers\": \"kafka:9092\", \"database.history.kafka.topic\": \"dbhistory.inventory\" } }"

您修改它以包含您的实际源数据库的详细信息，例如

curl -i -X PUT -H  "Content-Type:application/json" \
    http://localhost:8083/connectors/source-mysql-01/config \
    -d '{
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "tasks.max": "1",
    "database.hostname": "XXX.XXX.X.XXX",
    "database.port": "3306",
    "database.user": "ZZZZZ",
    "database.password": "PPPPP",
    "database.server.id": "184054",
    "database.server.name": "dbserver1",
    "database.whitelist": "YYYYY",
    "database.history.kafka.bootstrap.servers": "kafka:9092",
    "database.history.kafka.topic": "dbhistory.YYYYY"
}'

请注意，我也已更改为 PUT 而不是 POST，因为这意味着您可以重新运行该命令来修改同名的现有连接器（如果不存在则创建它）。
