[Java知识库]Docker搭建Seata服务并注册到Nacos中

一 获取镜像

docker search seata

docker pull seataio/seata-server

二 创建本地Seata数据库

? ? ? ? seata的官方数据库脚本seata/mysql.sql at develop · seata/seata · GitHub:fire: Seata is an easy-to-use, high-performance, open source distributed transaction solution. - seata/mysql.sql at develop · seata/seatahttps://github.com/seata/seata/blob/develop/script/server/db/mysql.sql

三 Seata的配置文件配置到配置中心nacos中

????????获取seata源码

git clone https://github.com/seata/seata.git

????????进入script目录修改配置，这里只是展示部分配置

????????

?????????使得配置进入写入Nacos中

sh nacos-config.sh -h nacos访问的ip -p 8848 -g SEATA_GROUP -t 自定义的命名空间id

????????

? ? ? ? nacos配置中心的seata配置

????????

四 配置seata注册nacos的文件

mkdir /data/seata/config

? ? ? ? registry.conf

registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    group = "SEATA_GROUP"
    cluster = "default"
	serverAddr = "ip:8848"
    namespace = "b94cfd49-3743-4bac-b1d3-41dcc2d07070"
    username = "nacos"
    password = "nacos"
  }
}

config {
  type = "nacos"
  nacos {
    serverAddr = "ip:8848"
    namespace = "b94cfd49-3743-4bac-b1d3-41dcc2d07070"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
}

? ? ? ? file.conf

store {
  ## store mode: file、db、redis
  mode = "db"
  ## rsa decryption public key
  publicKey = "1"
  ## file 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"
    url = "jdbc:mysql://ip:3306/seata"
    user = "root"
    password = "root"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

五 启动seata

????????启动命令

docker run --name seata \ -p 8091:8091 \ -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \ -e SEATA_IP=IP \ -v /data/seata/config:/root/seata-config \ -d --restart always seataio/seata-server
