1.2 快速开始(docker)

1.2.1 关于本节

  • 本节内容为您介绍如何通过dockerhub上的txle镜像快速启动一个txle的demon

1.2.2 安装准备

  • 安装docker

1.2.3 安装过程

按照顺序依次执行以下docker命令:

  1. 创建网络 
     $ docker network create --subnet=172.20.0.0/24 --gateway=172.20.0.254 txle_net
  2. 运行consul 
     $ docker volume create consul_data
 $ docker run -d --name=consul -v consul_data:/consul/data -p 8500:8500 --network=txle_net --ip=172.20.0.1 consul agent -server -ui -node=1 -client=0.0.0.0 -bootstrap
  3. 运行MySQL 
     $ docker run -d --name=backend-mysql -p 3306:3306 --network=txle_net --ip=172.20.0.11 -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=txle mysql:5.7 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
  4. 运行txle server 
     $ docker run -itd --name=txle-server-1 -p 8090:8090 --network=txle_net --ip=172.20.0.21 actiontech/txle-server
  5. 运行spring boot demo 
     $ docker run -itd --name=global -p 8000:8000 --network=txle_net --ip=172.20.0.31 actiontech/txle-global
 $ docker run -itd --name=transfer --network=txle_net --ip=172.20.0.32 actiontech/txle-transfer
 $ docker run -itd --name=user --network=txle_net --ip=172.20.0.33 actiontech/txle-user
 $ docker run -itd --name=merchant --network=txle_net --ip=172.20.0.34 actiontech/txle-merchant

1.2.4 使用工具发起全局事务

  1. 发起转账1元，转账将会成功 
     $ curl http://${host_address}:8000/testGlobalTransaction/1/1/1
 $ ok

  2. 访问数据库查看账户余额 

     $ docker exec -it backend-mysql bash
 # mysql -uroot -p123456
 mysql> select * from db1.txle_sample_transfer;
 +----+--------+------------+---------+--------+--------+---------+---------------------+
 | id | userid | merchantid | amount  | payway | status | version | createtime          |
 +----+--------+------------+---------+--------+--------+---------+---------------------+
 |  1 |      1 | 1          | 1.00000 |      1 |      1 |       0 | 2019-10-30 09:47:54 |
 +----+--------+------------+---------+--------+--------+---------+---------------------+
 1 row in set (0.00 sec)

 mysql> select * from db2.txle_sample_user;
 +----+------+-----------+---------+---------------------+
 | id | name | balance   | version | createtime          |
 +----+------+-----------+---------+---------------------+
 |  1 | user | 999.00000 |       1 | 2019-10-30 09:47:30 |
 +----+------+-----------+---------+---------------------+
 1 row in set (0.00 sec)

 mysql> select * from db3.txle_sample_merchant;
 +----+----------+---------+---------+---------------------+
 | id | name     | balance | version | createtime          |
 +----+----------+---------+---------+---------------------+
 |  1 | merchant | 1.00000 |       1 | 2019-10-30 09:47:31 |
 +----+----------+---------+---------+---------------------+
 1 row in set (0.00 sec)

    txle_sample_transfer记录了一条交易成功的记录，txle_sample_user和txle_sample_merchant数据正常记录

  3. 根据示例代码里的设定发起转账金额大于200元，第二个子服务merchant会报错导致转账将会失败 
     $ curl http://${host_address}:8000/testGlobalTransaction/1/300/1
 $ {"timestamp":1572429018848,"status":500,"error":"Internal Server Error","exception":"org.springframework.web.client.HttpServerErrorException","message":"500 null","path":"/testGlobalTransaction/1/300/1"}

  4. 访问数据库查看账户余额 

     $ docker exec -it backend-mysql bash
 # mysql -uroot -p123456
 mysql> select * from db1.txle_sample_transfer;
 +----+--------+------------+-----------+--------+--------+---------+---------------------+
 | id | userid | merchantid | amount    | payway | status | version | createtime          |
 +----+--------+------------+-----------+--------+--------+---------+---------------------+
 |  1 |      1 | 1          |   1.00000 |      1 |      1 |       0 | 2019-10-30 09:47:54 |
 |  2 |      1 | 1          | 300.00000 |      1 |      2 |       0 | 2019-10-30 09:50:18 |
 +----+--------+------------+-----------+--------+--------+---------+---------------------+
 2 rows in set (0.00 sec)

 mysql> select * from db2.txle_sample_user;
 +----+------+-----------+---------+---------------------+
 | id | name | balance   | version | createtime          |
 +----+------+-----------+---------+---------------------+
 |  1 | user | 999.00000 |       1 | 2019-10-30 09:47:30 |
 +----+------+-----------+---------+---------------------+
 1 row in set (0.00 sec)

 mysql> select * from db3.txle_sample_merchant;
 +----+----------+---------+---------+---------------------+
 | id | name     | balance | version | createtime          |
 +----+----------+---------+---------+---------------------+
 |  1 | merchant | 1.00000 |       1 | 2019-10-30 09:47:31 |
 +----+----------+---------+---------+---------------------+
 1 row in set (0.01 sec)

    txle_sample_transfer记录了一条交易失败的记录，txle_sample_user和txle_sample_merchant数据回滚
