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
bash
docker pull seataio/seata-server:2.0.0
查看nacos、mysql、宿主机的ip
bash
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,

PRIMARY KEY (`xid`),

) ENGINE = InnoDB

-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`

) 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`)
) ENGINE = InnoDB
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。

运行seata容器
bash
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
