部署Seata前记得启动Nacos
1.下载Seata
GitHub下载
2.配置config.txt
在conf目录创建config.txt，并配置，可参考 官网例子
# 定义组，应用中也需要对应
service.vgroupMapping.nacos-demo-group=default
store.mode=db|redis
-----db-----
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true
store.db.user=root
store.db.password=123456
----redis----
store.redis.host=127.0.0.1
store.redis.port=6379
store.redis.maxConn=10
store.redis.minConn=1
store.redis.database=0
store.redis.password=null
store.redis.queryLimit=100
3.配置registry.conf
registry {# file 、nacos 、eureka、redis、zk、consul、etcd3、sofatype = "nacos"loadBalance = "RandomLoadBalance"loadBalanceVirtualNodes = 10nacos {application = "seata-server"serverAddr = "127.0.0.1:8848"group = "DEFAULT_GROUP"namespace = ""cluster = "default"username = "nacos"password = "nacos"}redis {serverAddr = "localhost:6379"db = 0password = ""cluster = "default"timeout = 0}
}config {# file、nacos 、apollo、zk、consul、etcd3type = "nacos"nacos {serverAddr = "127.0.0.1:8848"namespace = ""group = "DEFAULT_GROUP"username = "nacos"password = "nacos"}
}4.配置nacos-config.sh
当前文件nacos-config.sh在config.txt文件下一级目录，可在config.txt所在目录下创建一个文件夹，再创建nacos-config.sh文件，
文件内容可参考 官网例子
记得将host，port，group，username，password修改与自己Nacos相同的配置

elseecho " init nacos config fail. "
fi在当前目录下运行nacos-config.sh文件，将config.txt中的配置注册到Nacos
#修改为可执行文件
chmod +x nacos-config.sh
#运行
sh nacos-config.sh当注册好后nacos的配置列表将配置config.txt内的所有配置 ，如下图
5.启动Seata
在Seata/bin下运行seata-server.sh
sh seata-server.sh正常运行后在nacos服务列表中可看到Seata服务
注意：启动前，db模式需要创建global_table, branch_table, lock_table表
相关建表脚本在GitHub的/script/server/db/ 目录下
