docker部署seata-1.2.0

docker部署seata-1.2.0

默認要安裝activemq的主機上已經安裝了docker。

官方部署說明（傳送門）

1、查詢seata：

docker search seata

2、按照name接取鏡像

docker pull seataio/seata-server

3、創建seata-config目錄，並在該目錄下邊新建registry.conf、file.conf文件。

這裏我們使用zookeeper爲註冊中心，並指定指定 file.conf 配置文件。因此registry.conf內容如下：

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "zk"

  zk {
    cluster = "default"
    serverAddr = "xxx.xxx.xxx.xxx:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "file"

  file {
    name = "file:/root/seata-config/file.conf"
  }
}

注：serverAddr爲zookeeper地址；

       config.file.name = "file:docker容器內的file.conf配置文件"；

file.conf文件內容如下：

## transaction log store, only used in seata-server
store {
  ## store mode: file、db
  mode = "db"

  ## database store property
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://xxx.xxx.xxx.xxx:3306/seata"
    user = "xxxxx"
    password = "xxxxx"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

4、創建數據庫和表，全局事務會話信息由3塊內容構成，全局事務-->分支事務-->全局鎖，對應表global_table、branch_table、lock_table

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,

    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),

5、啓動docker容器

docker run -d --name seata-server \
        -p 8091:8091 \
        -e SEATA_IP=xxx.xxx.xxx.xxx \
        -e STORE_MODE=db \
        -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
        -v /opt/seata-config:/root/seata-config  \
        seataio/seata-server

注：其中 -e 用於配置環境變量， -v 用於掛載宿主機的目錄

        -v 本地目錄:docker容器目錄

6、查看

docker ps

7、查看運行日誌

docker logs -f b41aba2eff17

8、查看seata容器內目錄結構

docker exec -it seata-server sh
