docker-compose 部署 Seata整合nacos,Postgresql 為DB存儲(chǔ)
環(huán)境
詳情環(huán)境可參考
https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E
我這里
<spring.cloud.alibaba-version>2021.1</spring.cloud.alibaba-version>
所有選擇seata版本為 1.3.0
docker-compose 部署seata
前提：已經(jīng)安裝好nacos和postgresql
- 創(chuàng)建好數(shù)據(jù)庫(kù) 名稱：seata
執(zhí)行以下sql:
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS public.global_table
(
xid VARCHAR(128) NOT NULL,
transaction_id BIGINT,
status SMALLINT 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 TIMESTAMP(0),
gmt_modified TIMESTAMP(0),
CONSTRAINT pk_global_table PRIMARY KEY (xid)
);
CREATE INDEX idx_status_gmt_modified ON public.global_table (status, gmt_modified);
CREATE INDEX idx_transaction_id ON public.global_table (transaction_id);
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS public.branch_table
(
branch_id BIGINT NOT NULL,
xid VARCHAR(128) NOT NULL,
transaction_id BIGINT,
resource_group_id VARCHAR(32),
resource_id VARCHAR(256),
branch_type VARCHAR(8),
status SMALLINT,
client_id VARCHAR(64),
application_data VARCHAR(2000),
gmt_create TIMESTAMP(6),
gmt_modified TIMESTAMP(6),
CONSTRAINT pk_branch_table PRIMARY KEY (branch_id)
);
CREATE INDEX idx_xid ON public.branch_table (xid);
-- the table to store lock data
CREATE TABLE IF NOT EXISTS public.lock_table
(
row_key VARCHAR(128) NOT NULL,
xid VARCHAR(128),
transaction_id BIGINT,
branch_id BIGINT NOT NULL,
resource_id VARCHAR(256),
table_name VARCHAR(32),
pk VARCHAR(36),
status SMALLINT NOT NULL DEFAULT 0,
gmt_create TIMESTAMP(0),
gmt_modified TIMESTAMP(0),
CONSTRAINT pk_lock_table PRIMARY KEY (row_key)
);
comment on column public.lock_table.status is '0:locked ,1:rollbacking';
CREATE INDEX idx_branch_id ON public.lock_table (branch_id);
CREATE INDEX idx_xid ON public.lock_table (xid);
CREATE INDEX idx_status ON public.lock_table (status);
CREATE TABLE distributed_lock (
lock_key VARCHAR(20) NOT NULL,
lock_value VARCHAR(20) NOT NULL,
expire BIGINT NOT NULL,
CONSTRAINT pk_distributed_lock_table PRIMARY KEY (lock_key)
);
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);
其他的sql可以參考:
https://github.com/seata/seata/tree/develop/script/server/db
服務(wù)器層級(jí)結(jié)構(gòu):
2.先運(yùn)行一個(gè)seata容器,目的為了把seata相關(guān)的配置文件拷貝處理，方便后續(xù)使用
docker run --name seata-server -p 8091:8091 -d seataio/seata-server:1.3.0
docker cp seata-server:/seata-server /opt/seata/resources
3.然后將該容器刪除
docker stop seata-server
docker rm seata-server
4, 修改后的file.conf
## transaction log store, only used in seata-server
store {
## store mode: file、db、redis
mode = "db"
## file store property
file {
## store location dir
dir = "sessionStore"
# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
maxBranchSessionSize = 16384
# globe session size , if exceeded throws exceptions
maxGlobalSessionSize = 512
# file buffer size , if exceeded allocate new buffer
fileWriteBufferCacheSize = 16384
# when recover batch read size
sessionReloadReadSize = 100
# async, sync
flushDiskMode = async
}
## database store property
db {
## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
## datasource = "druid"
## mysql/oracle/postgresql/h2/oceanbase etc.
dbType = "postgresql"
driverClassName = "org.postgresql.Driver"
url = "jdbc:postgresql://101.35.249.216:5432/seata"
user = "root"
password = "root"
minConn = 5
maxConn = 30
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
maxWait = 5000
}
## redis store property
redis {
host = "127.0.0.1"
port = "6379"
password = ""
database = "0"
minConn = 1
maxConn = 10
queryLimit = 100
}
}
修改細(xì)節(jié)如下圖:
修改后的registry.conf：

nacos {
application = "seata-server"

username = "nacos"
password = "Carbonease@2022"
}
eureka {
serviceUrl = "http://localhost:8761/eureka"
application = "default"
weight = "1"
}
redis {
serverAddr = "localhost:6379"
db = 0
password = ""
cluster = "default"
timeout = 0
}
zk {
cluster = "default"
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
}
consul {
cluster = "default"
serverAddr = "127.0.0.1:8500"
}
etcd3 {
cluster = "default"
serverAddr = "http://localhost:2379"
}
sofa {
serverAddr = "127.0.0.1:9603"
application = "default"
region = "DEFAULT_ZONE"
datacenter = "DefaultDataCenter"
cluster = "default"
group = "SEATA_GROUP"
addressWaitTime = "3000"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "nacos"
nacos {
serverAddr = "nacos.carbonease.cn:80"
namespace = "cfa514ed-1caf-4d2b-8645-8dbee0f3933f"
group = "SEATA_GROUP"
username = "nacos"
password = "Carbonease@2022"
}
consul {
serverAddr = "127.0.0.1:8500"
}
apollo {
appId = "seata-server"
apolloMeta = "http://192.168.1.204:8801"
namespace = "application"
}
zk {
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
}
etcd3 {
serverAddr = "http://localhost:2379"
}
file {
name = "file.conf"
}
}

修改sh文件的權(quán)限
chmod +x nacos-config.sh
將配置文件推送至Nacos:

命令格式：
sh nacos-config.sh -h Nacos地址 -p nacos端口號(hào) -g SEATA_GROUP（此處是配置文件的分組名稱，可以不改） -t 在nacos配置的seata命名空間ID
推送成功
創(chuàng)建 docker-compose.yml 文件

客戶端和服務(wù)端的版本一定要一致，否則可能出現(xiàn)

jdk8以上的需要設(shè)置啟動(dòng)參數(shù):

然后，服務(wù)所涉及到的數(shù)據(jù)庫(kù)需要加上日志表：
-- 日志表
CREATE TABLE IF NOT EXISTS public.undo_log
(
id BIGINT NOT NULL,
branch_id BIGINT NOT NULL,
xid VARCHAR(100) NOT NULL,
context VARCHAR(128) NOT NULL,
rollback_info bytea NOT NULL,
log_status INT NOT NULL,
log_created TIMESTAMP(6) NOT NULL,
log_modified TIMESTAMP(6) NOT NULL,
CONSTRAINT pk_undo_log PRIMARY KEY (id)
);
CREATE SEQUENCE undo_log_id_seq START 1;
最后:
服務(wù)A 調(diào)用 服務(wù)B
在服務(wù)A的Service上加注解
@GlobalTransactional(rollbackFor = Exception.class)
服務(wù)B是Service上加注解文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-693866.html
@Transactional(rollbackFor = Exception.class)
大功告成!!文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-693866.html
