注意事项
- 避免直接拉取latest版本镜像，latest版本并不一定是released版本，为避免不必要的问题，请到docker镜像仓库确定要拉取的镜像版本。
快速开始
【无注册中心，file存储】
该模式下，不需要注册中心，也不需要任何第三方存储中心。
docker-compose.yaml
version: "3.1"
services:
seata-server:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8091:8091"
environment:
- SEATA_PORT=8091
- STORE_MODE=file
【无注册中心，DB存储】
db模式需要在数据库创建对应的表结构，建表脚本。
如无法访问，请点击 【mysql表结构】、【oracle表结构】、【postgresql表结构】。
（1）准备file.conf配置文件
其他存储模式可参考file.example.conf
# 1.5.0版本后，默认事务分组改成了default_tx_group
# 参考：service.vgroupMapping.default_tx_group=default
service.vgroupMapping.my_test_tx_group=default
# 存储模式
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
# 需要根据mysql的版本调整driverClassName
# mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver
# mysql8以下版本的driver：com.mysql.jdbc.Driver
store.db.driverClassName=com.mysql.cj.jdbc.Driver
# 注意调整host和port
store.db.url=jdbc:mysql://127.0.0.1:3306/seata-server?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
# 数据库用户名
store.db.user=root
# 用户名密码
store.db.password=123456
（2）准备registry.conf文件
其他注册中心、配置中心方式可参考registry.example.conf
直连模式（无注册中心）
registry {
type = "file"
}
config {
type = "file"
file {
name="file:/root/seata-config/file.conf"
}
}
（3）准备docker-compose.yaml文件
version: "3.1"
services:
seata-server:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8091:8091"
environment:
- SEATA_PORT=8091
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
volumes:
# 需要把file.conf和registry.conf都放到./seata-server/config文件夹中
- "./seata-server/config:/root/seata-config"
【nacos注册中心，db存储】
db模式需要在数据库创建对应的表结构，建表脚本。
如无法访问，请点击 【mysql表结构】、【oracle表结构】、【postgresql表结构】。
（1）准备file.conf配置文件
其他存储模式可参考file.example.conf
# 1.5.0版本后，默认事务分组改成了default_tx_group
# 参考：service.vgroupMapping.default_tx_group=default
service.vgroupMapping.my_test_tx_group=default
# 存储模式
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
# 需要根据mysql的版本调整driverClassName
# mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver
# mysql8以下版本的driver：com.mysql.jdbc.Driver
store.db.driverClassName=com.mysql.cj.jdbc.Driver
# 注意调整host和port
store.db.url=jdbc:mysql://127.0.0.1:3306/seata-server?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
# 数据库用户名
store.db.user=root
# 用户名密码
store.db.password=123456
（2）准备registry.conf文件
nacos注册中心。
其他注册中心、配置中心方式可参考registry.example.conf
registry {
type = "nacos"
nacos {
# seata服务注册在nacos上的别名，客户端通过该别名调用服务
application = "seata-server"
# nacos服务的ip和端口
serverAddr = "127.0.0.1:8848"
# nacos上指定的namespace
namespace = ""
cluster = "default"
username = "nacos"
password = "nacos"
}
}
#【如果nacos服务是docker运行的话，config.type需要指定为file模式，否则会报错】
config {
type = "file"
file {
name="file:/root/seata-config/file.conf"
}
}
（3）准备docker-compose.yaml文件
version: "3.1"
services:
seata-server:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8091:8091"
environment:
# 指定seata服务启动端口
- SEATA_PORT=8091
# 注册到nacos上的ip。客户端将通过该ip访问seata服务。
# 注意公网ip和内网ip的差异。
- SEATA_IP=127.0.0.1
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
volumes:
# 需要把file.conf和registry.conf都放到./seata-server/config文件夹中
- "./seata-server/config:/root/seata-config"
【高可用部署】
seata高可用依赖于注册中心、数据库，可不依赖配置中心。
db模式需要在数据库创建对应的表结构，建表脚本。
如无法访问，请点击 【mysql表结构】、【oracle表结构】、【postgresql表结构】。
（1）准备file.conf配置文件
其他存储模式可参考file.example.conf
# 1.5.0版本后，默认事务分组改成了default_tx_group
# 参考：service.vgroupMapping.default_tx_group=default
service.vgroupMapping.my_test_tx_group=default
# 存储模式
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
# 需要根据mysql的版本调整driverClassName
# mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver
# mysql8以下版本的driver：com.mysql.jdbc.Driver
store.db.driverClassName=com.mysql.cj.jdbc.Driver
# 注意调整host和port
store.db.url=jdbc:mysql://127.0.0.1:3306/seata-server?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
# 数据库用户名
store.db.user=root
# 用户名密码
store.db.password=123456
（2）准备registry.conf文件
nacos注册中心。
其他注册中心、配置中心方式可参考registry.example.conf
registry {
type = "nacos"
nacos {
# seata服务注册在nacos上的别名，客户端通过该别名调用服务
application = "seata-server"
# nacos服务的ip和端口
serverAddr = "127.0.0.1:8848"
# nacos上指定的namespace
namespace = ""
cluster = "default"
username = "nacos"
password = "nacos"
}
}
#【如果nacos服务是docker运行的话，config.type需要指定为file模式，否则会报错】
config {
type = "file"
file {
name="file:/root/seata-config/file.conf"
}
}
（3）准备docker-compose.yaml文件
只要保持配置一致，seata服务可在一台机器上部署多实例，也可同时部署在多台不同的主机下面实现服务高可用。
version: "3.1"
services:
# seata服务1
seata-server-1:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8091:8091"
environment:
# 指定seata服务启动端口
- SEATA_PORT=8091
# 注册到nacos上的ip。客户端将通过该ip访问seata服务。
# 注意公网ip和内网ip的差异。
- SEATA_IP=127.0.0.1
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
volumes:
# 需要把file.conf和registry.conf都放到./seata-server/config文件夹中
- "./seata-server/config:/root/seata-config"
# seata服务2
seata-server-2:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8092:8092"
environment:
# 指定seata服务启动端口
- SEATA_PORT=8092
# 注册到nacos上的ip。客户端将通过该ip访问seata服务。
# 注意公网ip和内网ip的差异。
- SEATA_IP=127.0.0.1
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
volumes:
# 需要把file.conf和registry.conf都放到./seata-server/config文件夹中
- "./seata-server/config:/root/seata-config"
# seata服务3
seata-server-3:
image: seataio/seata-server:1.4.2
hostname: seata-server
ports:
- "8093:8093"
environment:
# 指定seata服务启动端口
- SEATA_PORT=8093
# 注册到nacos上的ip。客户端将通过该ip访问seata服务。
# 注意公网ip和内网ip的差异。
- SEATA_IP=127.0.0.1
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
volumes:
# 需要把file.conf和registry.conf都放到./seata-server/config文件夹中
- "./seata-server/config:/root/seata-config"
环境变量
seata-server 支持以下环境变量：
- 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,file,redis(Seata-Server 1.3及以上版本支持), 默认是file
- SERVER_NODE
可选, 用于指定seata-server节点ID, 如
1,2,3..., 默认为根据ip生成
- 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：
