docker部署seata 2.0.0

2024.11.08更新

云服务器上使用docker network inspect bridge命令可能会查询不到某些容器（比如mysql）的ip地址，这时可使用以下命令查看容器ip地址：

docker inspect <container_id_or_name> | grep IPAddress

环境准备

当前使用的环境：
MySQL：8.0+
nacos：2.2.3

关于如何在docker中部署nacos 2.2.3，请参考之前文章：
docker部署nacos 2.2.3

拉取镜像

docker pull seataio/seata-server:2.0.0

查看nacos、mysql、宿主机的ip

docker network inspect bridge

结果如下图：

宿主机ip为：192.168.246.128
nacos为：172.17.0.6
mysql为：172.17.0.3
请记住这几个ip地址，之后创建配置文件时要用

建立数据库

在mysql中新建seata数据库，并使用以下SQL创建表：

-- -------------------------------- 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,

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`

  `row_key`        VARCHAR(128) NOT NULL,
  `xid`            VARCHAR(128),

) ENGINE = InnoDB
  DEFAULT CHARSET = utf8mb4;

CREATE TABLE IF NOT EXISTS `distributed_lock`

  `lock_key`       CHAR(20) NOT NULL,
  `lock_value`     VARCHAR(20) NOT NULL,
  `expire`         BIGINT,
  primary key (`lock_key`)

  DEFAULT CHARSET = utf8mb4;

INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);

创建application.yml

在/mydata/seata-server/resources目录下新建文件application.yml ，/mydata/seata-server/resources是自定义挂载目录，可修改。

注意：要将该文件中的mysql地址和nacos地址修改成你自己的

运行seata容器

docker run --name seata-server \
-itd \
-p 8091:8091 \
-p 7091:7091 \
-e SEATA_IP="192.168.246.128" \
-e SEATA_PORT=8091 \
-v "/mydata/seata-server/resources/application.yml:/seata-server/resources/application.yml" \
seataio/seata-server:2.0.0

其中SEATA_IP：192.168.246.128为之前查到的宿主机ip

检验seata部署情况

访问网页：http://192.168.246.128:7091

nacos网页上查看seata服务详情，注意：ip要为宿主机ip，不是docker容器内网ip

以上两步都成功的情况下则部署成功
