Centos7安装seata1.3

Seata安装方案

1. Server端存储模式使用mysql
2. 注册中心使用nacos 1.3.1

1. 下载seata应用 http://seata.io/zh-cn/blog/download.html
2. 直接解压，进入conf目录修改file.conf和register.conf
   2.1 file.conf指定存储模式为数据库，并配置数据库相关信息

store {
## store mode: file、db、redis
mode = "db"

## 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 = "mysql"
  driverClassName = "com.mysql.jdbc.Driver"
  url = "jdbc:mysql://127.0.0.1:3306/seata_server"
  user = "root"
  password = "xxxxxx"
  minConn = 5
  maxConn = 30
  globalTable = "global_table"
  branchTable = "branch_table"
  lockTable = "lock_table"
  queryLimit = 100
  maxWait = 5000
  } 
}
    

2.2 register.conf 指定注册中心为nacos

registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"

nacos {
 application = "seata-server"
 serverAddr = "localhost:8848"
 group = "SEATA_GROUP"
 namespace = ""
 cluster = "default"
 username = "nacos"
 password = "nacos"
 }
}

config {
# file、nacos 、apollo、zk、consul、etcd3
type = "file"

file {
 name = "file.conf"
}
}

3. 数据库新建表

启动参数介绍：

参数	全写	作用	备注
-h	--host	指定在注册中心注册的 IP	不指定时获取当前的 IP，外部访问部署在云环境和容器中的 server 建议指定
-p	--port	指定 server 启动的端口	默认为 8091
-m	--storeMode	事务日志存储方式	支持file,db,redis，默认为 file 注:redis需seata-server 1.3版本及以上
-n	-serverNode	用于指定seata-server节点ID	如 1,2,3..., 默认为 1
-e	-seataEnv	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

4. 启动seata

./bin/seata-server.sh -p 8091 -h 127.0.0.1 -m file

等待一会后，日志打印如下信息，表示启动成功。

访问nacos，seata已经成功注册到nacos
