Seata安装并注册集成到Nacos服务上

目录

一.工具地址与版本

二.解压与配置

三.创建数据库，执行脚本

四.启动与调试

五.seata高可用

六.查看启动情况

---

一.工具地址与版本

1.nacos-server-2.0.3

下载地址：Releases · alibaba/nacos · GitHub

2.seata-server-1.4.2

下载地址：https://github.com/seata/seata/releases

3.jdk11

注意：这里只搞seata，其他的自行安装

二.解压与配置

1.解压

tar -zvxf seata-server-1.4.2.tar.gz

 2.配置文件file.conf, 修改了mode="db" ,去掉了其他的配置, 修改数据库连接地址数据库用户密码

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db"
  ## rsa decryption public key
  publicKey = ""

  ## 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.cj.jdbc.Driver"
    ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
    url = "jdbc:mysql://192.168.99.133:3306/seata?rewriteBatchedStatements=true"
    user = "数据库账号"
    password = "数据库密码"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

}

3.修改配置文件registry.conf ，已经清掉多余的配置了

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

  nacos {
	# nacos注册后的服务名称
    application = "seata-server"
	# seata 集成nacos的nacos地址与端口
    serverAddr = "192.168.99.133:8848"
	# 还不熟练的时候默认即可
    group = "DEFAULT_GROUP"
	# nacos的命名空间，为空默认在public下
    namespace = "cc0bd646-7444-4611-ae53-793f494b174e"
	# 默认即可
    cluster = "default"
	# nacos的账号，如果没有可以为空
    username = ""
	# nacos的密码，如果没有可以为空
    password = ""
  }
  # type="file" 的时候使用
  file {
    name = "file.conf"
  }
}

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

  nacos {
    serverAddr = "192.168.99.133:8848"
    namespace = "cc0bd646-7444-4611-ae53-793f494b174e"
    group = "DEFAULT_GROUP"
    username = ""
    password = ""
	# nacos需要创建seataServer.properties方便编辑操作
    dataId = "seataServer.properties"
  }
  # type="file" 的时候使用
  file {
    name = "file.conf"
  }
}

4.新建nacos配置文件 seataServer.properties

三.创建数据库，执行脚本

1.先创建名称为seata数据库schema

2.执行脚本

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

SET FOREIGN_KEY_CHECKS = 1;

四.启动与调试

1.方式1直接启动

nohup sh seata-server.sh

2.方式2修改ip, port并指定输出日志地址启动

nohup sh seata-server.sh -h 192.168.99.133 -p 8091 >/data/logs/seata1.out 2>&1 &

 注意：虚拟机不指定IP会出现IP不对的场景

五.seata高可用

1.一份配置指定不同端口，或者一份配置拷贝不同服务器使用

nohup sh seata-server.sh -h 192.168.99.133 -p 8091 >/data/logs/seata1.out 2>&1 &
nohup sh seata-server.sh -h 192.168.99.133 -p 8092 >/data/logs/seata2.out 2>&1 &

六.查看启动情况
