1.拉取镜像

docker pull seataio/seata-server

2.新增配置文件

2.1 registry.conf

在我们服务器目录上创建文件：registry.conf

registry.conf内容如下：

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

  nacos {
    application = "seata-server"
    serverAddr = "192.168.1.2:8848" #nacos内网地址
    namespace = ""
    cluster = "default"
    username = ""
    password = ""
  }
  file {
    name = "file.conf"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "file"
  file {
    name = "file.conf"
  }
}

2.2 file.conf

继续创建文件file.conf，内容如下：

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/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName  = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://192.168.1.2:3306/seata" #数据库内网地址
    user = "root"
    password = "root"
    min-conn = 5
    max-conn = 30
    global.table = "global_table"
    branch.table = "branch_table"
    lock-table = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

在我们的数据库中创建数据库seata，同时在seata中创建我们file.conf里指向的表，sql语句如下：

drop table if exists `global_table`;
create table `global_table` (
  `xid` varchar(128)  not null,
  `transaction_id` bigint,
  `status` tinyint not null,
  `application_id` varchar(32),
  `transaction_service_group` varchar(32),
  `transaction_name` varchar(128),
  `timeout` int,
  `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`)
);


drop table if exists `branch_table`;
create table `branch_table` (
  `branch_id` bigint not null,
  `xid` varchar(128) not null,
  `transaction_id` bigint ,
  `resource_group_id` varchar(32),
  `resource_id` varchar(256) ,
  `lock_key` varchar(128) ,
  `branch_type` varchar(8) ,
  `status` tinyint,
  `client_id` varchar(64),
  `application_data` varchar(2000),
  `gmt_create` datetime,
  `gmt_modified` datetime,
  primary key (`branch_id`),
  key `idx_xid` (`xid`)
);


drop table if exists `lock_table`;
create table `lock_table` (
  `row_key` varchar(128) not null,
  `xid` varchar(96),
  `transaction_id` long ,
  `branch_id` long,
  `resource_id` varchar(256) ,
  `table_name` varchar(32) ,
  `pk` varchar(36) ,
  `gmt_create` datetime ,
  `gmt_modified` datetime,
  primary key(`row_key`)
);

3.启动seata

docker run --name seata-server \
-p 8091:8091 \
-e SEATA_IP=192.168.1.2 \
-e SEATA_PORT=8091 \
-e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
-v /home/ninesun/soft/seata/config:/root/seata-config  \
-d seataio/seata-server

我来解释一下上面都是什么代表什么:

• SEATA_IP
  可选, 指定seata-server启动的IP, 该IP用于向注册中心注册时使用, 如eureka等
• SEATA_PORT
  可选, 指定seata-server启动的端口, 默认为 8091
• STORE_MODE
  可选, 指定seata-server的事务日志存储方式, 支持db 和 file, 默认是 file
• SERVER_NODE
  可选, 用于指定seata-server节点ID, 如 1,2,3…, 默认为 1
• SEATA_ENV
  可选, 指定 seata-server 运行环境, 如 dev, test 等, 服务启动时会使用 registry-dev.conf 这样的配置
• SEATA_CONFIG_NAME
  可选, 指定配置文件位置, 如 file:/root/registry, 将会加载 /root/registry.conf 作为配置文件，如果需要同时指定 file.conf文件，需要将registry.conf的config.file.name的值改为类似file:/root/file.conf：

我们需要修改启动指令的内容如下：

4.验证是否启动成功

打开nacos，如果出现以下内容说明你配置成功：
