以下是一個簡短的範例，示範如何使用引導方式部署 MySQL Router 以使用 InnoDB Cluster。如需其他資訊，請參閱 --bootstrap 和其他引導選項。

此範例使用 --directory 選項建立獨立的 MySQL Router 執行個體，啟用 Socket，使用 --account 自訂 Router 的 MySQL 使用者名稱，並將 --account-create 設定為 always，以便僅在帳戶不存在時才引導。此範例假設名為 myCluster 的 InnoDB Cluster 已存在。

$> mysqlrouter --bootstrap root@localhost:3310 --directory /tmp/myrouter 
  --conf-use-sockets --account routerfriend --account-create always

Please enter MySQL password for root: 

# Bootstrapping MySQL Router instance at '/tmp/myrouter'...

Please enter MySQL password for routerfriend: 

- Creating account(s) 
- Verifying account (using it to run SQL queries that would be run by Router)
- Storing account in keyring
- Adjusting permissions of generated files
- Creating configuration /tmp/myrouter/mysqlrouter.conf

# MySQL Router configured for the InnoDB Cluster 'myCluster'

After this MySQL Router has been started with the generated configuration

    $ mysqlrouter -c /tmp/myrouter/mysqlrouter.conf

the cluster 'myCluster' can be reached by connecting to:

## MySQL Classic protocol

- Read/Write Connections: localhost:6446, /tmp/myrouter/mysql.sock
- Read/Only Connections:  localhost:6447, /tmp/myrouter/mysqlro.sock

## MySQL X protocol

- Read/Write Connections: localhost:6448, /tmp/myrouter/mysqlx.sock
- Read/Only Connections:  localhost:6449, /tmp/myrouter/mysqlxro.sock

此時，引導程序已在指定的目錄中建立一個 mysqlrouter.conf 檔案，且結果會顯示如何啟動此 MySQL Router 執行個體。產生的 MySQL Router 目錄看起來類似於

$> ls -l | awk '{print $9}'

data/
log/
mysqlrouter.conf
mysqlrouter.key
run/
start.sh
stop.sh

產生的 MySQL Router 組態檔 (mysqlrouter.conf) 看起來類似於

data_folder=/tmp/myrouter/data

在此範例中，MySQL Router 設定了四個連接埠和四個 Socket。預設會新增連接埠，而 Socket 是透過傳入 --conf-use-sockets 新增的。名為「myCluster」的 InnoDB Cluster 是中繼資料的來源，而 destinations 正在使用 InnoDB Cluster 中繼資料快取來動態設定主機資訊。相關的命令列選項

為了示範 MySQL Router 的行為，以下用戶端 (應用程式) 連線到連接埠 6446，但會連線到連接埠 3310 上的 MySQL 執行個體。

$> mysql -u root -h 127.0.0.1 -P 6446 -p

...

mysql> select @@port;
