一、下載下傳seata服務端seata-server
seata-server下載下傳位址:https://seata.io/zh-cn/blog/download.html
這裡以seata-server-1.3為例:https://github.com/seata/seata/releases/download/v1.3.0/seata-server-1.3.0.zip
二、執行官網提供的sql檔案,修改registry.conf配置檔案
1、執行官網提供的sql檔案建表
https://github.com/seata/seata/tree/1.3.0/script/server/db
2、修改registry.conf配置檔案
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "你的nacos位址"
group = "SEATA_GROUP"
namespace = "命名空間"
cluster = "default"
username = "nacos使用者名"
password = "nacos密碼"
}
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 = "你的nacos位址"
namespace = "命名空間"
group = "SEATA_GROUP"
username = "nacos使用者名"
password = "nacos密碼"
}
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"
}
}
三、将配置資訊上傳至nacos配置中心
1、官方已經提供好了config.txt,下載下傳位址:https://github.com/seata/seata/tree/develop/script/config-center
2、修改config.txt配置檔案中的内容(ps:也可以上傳至nacos後在nacos配置中心上進行修改)
需要修改的内容如下:
service.vgroupMapping.nanyiba_global_tx_group=default
store.mode=db
store.db.url=jdbc:mysql://mysqlip:mysql端口号/庫名?useUnicode=true
store.db.user=mysql賬戶
store.db.password=mysql密碼
nanyiba_global_tx_group是要修改的地方,這裡修改的内容,後面整合時需要的
3、将config.txt中的配置資訊上傳至nacos配置中心
執行指令如下:
sh nacos-config.sh -h 你的nacosIP位址 -p 你的nacos端口 -g SEATA_GROUP -t 命名空間 -u nacos使用者嗎 -w nacos密碼
四、啟動seata-server服務端
啟動指令:
./bin/seata-server.sh -p 8091 -h 你部署seata-server伺服器的ip位址 -p 你想配置seata-server的端口号 -m db
具體參數文檔:https://seata.io/zh-cn/docs/ops/deploy-server.html
ps:這裡如果不指定ip位址,後面整合時,應用啟動時它找的是你seata-server内網ip位址
五、seata整合spring cloud alibaba
1、pom引入依賴
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
</dependency>
2、application.yml配置檔案
spring:
cloud:
alibaba:
seata:
tx-service-group: nanyiba-global-tx-group #事務分組名稱
seata:
registry:
type: nacos
nacos:
application: seata-server
server-addr: nacosd位址
group: SEATA_GROUP
namespace: 命名空間
cluster: default
username: nacos賬戶
password: nacos密碼
config:
type: nacos
nacos:
server-addr: nacosd位址
group: SEATA_GROUP
namespace: 命名空間
username: nacos賬戶
password: nacos密碼
六、可能會出現的問題
問題:no available service ‘null’ found, please make sure registry config correct
提示:檢查application.yml配置檔案的事務分組名稱是否和nacos配置中心的保持一緻
