seata 1.4.2 安装部署(Linux环境)

Linux安装部署 seata server 1.4.2

下载安装包上传至服务器

1.首先从GitHub拉取seata压缩包

https://github.com/seata/seata/releases/download/v1.4.2/seata-server-1.4.2.zip

下载到本地后上传至服务器

或使用命令拉取

wget  https://github.com/seata/seata/releases/download/v1.4.2/seata-server-1.4.2.zip

2.解压安装包

unzip seata-server-1.4.2.zip

3.更改seata配置文件 seata-server-1.4.2/conf/registry.conf

需要修改的地方为registry节点下nacos节点相关配置信息及config节点下nacos节点

# registry 节点中配置信息主要用于seata服务注册在哪个注册中心上
# 例我这里选择的是nacos,则seata服务配置成狗后会注册到nacos上
registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  #更改seata服务注册类型,这里我们使用nacos
  type = "nacos"

  nacos {
    # 服务名称,可以随意定义
    application = "seata-server"
    # nacos服务ip
    serverAddr = "127.0.0.1:8848"
    # nacos分组,为空及默认DEFAULT_GROUP
    group = "SEATA_GROUP"
    # nacos命名空间,可为空
    namespace = "bdddefe8-6a4c-4aae-8fb7-b5a248493dfd"
    # nacos集群,保持默认就好
    cluster = "default"
    # nacos 账户
    username = "nacos"
    # nacos 密码
    password = "nacos"
  }
}
# config 节点中配置信息主要用于seata服务相关配置是从哪个注册中心中获取
config {
  # file、nacos 、apollo、zk、consul、etcd3
  # 更改seata服务配置信息类型为nacos
  type = "nacos"

  nacos {
    # 与registry节点下nacos配置信息保持议一致即可
    serverAddr = "127.0.0.1:8848"
    namespace = "bdddefe8-6a4c-4aae-8fb7-b5a248493dfd"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
}

随后更新seata-server-1.4.2/conf/file.conf 文件,进行交易日志存储及配置数据库相关信息

更新数据库连接地址及账户密码即可

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.jdbc.Driver"
    ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
    url = "jdbc:mysql://127.0.0.1:3306/seata?rewriteBatchedStatements=true"
    user = "mysql"
    password = "mysql"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

4.将seata配置导入至nacos中

特别说明:在二进制安装包没有对应文件,需要在源码包中找到对应文件。

在源码包中找到配置属性文件seata-1.4.2/script/config-center/config.txt,内容如下:

transport.type=TCP
transport.server=NIO
transport.heartbeat=true
transport.enableClientBatchSendRequest=false
transport.threadFactory.bossThreadPrefix=NettyBoss
transport.threadFactory.workerThreadPrefix=NettyServerNIOWorker
transport.threadFactory.serverExecutorThreadPrefix=NettyServerBizHandler
transport.threadFactory.shareBossWorker=false
transport.threadFactory.clientSelectorThreadPrefix=NettyClientSelector
transport.threadFactory.clientSelectorThreadSize=1
transport.threadFactory.clientWorkerThreadPrefix=NettyClientWorkerThread
transport.threadFactory.bossThreadSize=1
transport.threadFactory.workerThreadSize=default
transport.shutdown.wait=3
service.vgroupMapping.my_test_tx_group=default
service.default.grouplist=127.0.0.1:8091
service.enableDegrade=false
service.disableGlobalTransaction=false
client.rm.asyncCommitBufferLimit=10000
client.rm.lock.retryInterval=10
client.rm.lock.retryTimes=30
client.rm.lock.retryPolicyBranchRollbackOnConflict=true
client.rm.reportRetryCount=5
client.rm.tableMetaCheckEnable=false
client.rm.tableMetaCheckerInterval=60000
client.rm.sqlParserType=druid

client.rm.sagaBranchRegisterEnable=false
client.tm.commitRetryCount=5
client.tm.rollbackRetryCount=5
client.tm.defaultGlobalTransactionTimeout=60000
client.tm.degradeCheck=false
client.tm.degradeCheckAllowTimes=10
client.tm.degradeCheckPeriod=2000
store.mode=file
store.publicKey=
store.file.dir=file_store/data
store.file.maxBranchSessionSize=16384
store.file.maxGlobalSessionSize=512
store.file.fileWriteBufferCacheSize=16384
store.file.flushDiskMode=async
store.file.sessionReloadReadSize=100
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&rewriteBatchedStatements=true
store.db.user=username
store.db.password=password
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000
store.redis.mode=single
store.redis.single.host=127.0.0.1
store.redis.single.port=6379
store.redis.sentinel.masterName=
store.redis.sentinel.sentinelHosts=
store.redis.maxConn=10
store.redis.minConn=1
store.redis.maxTotal=100
store.redis.database=0
store.redis.password=
store.redis.queryLimit=100
server.recovery.committingRetryPeriod=1000
server.recovery.asynCommittingRetryPeriod=1000
server.recovery.rollbackingRetryPeriod=1000
server.recovery.timeoutRetryPeriod=1000
server.maxCommitRetryTimeout=-1
server.maxRollbackRetryTimeout=-1
server.rollbackRetryTimeoutUnlockEnable=false
client.undo.dataValidation=true
client.undo.logSerialization=jackson
client.undo.onlyCareUpdateColumns=true
server.undo.logSaveDays=7
server.undo.logDeletePeriod=86400000
client.undo.logTable=undo_log
client.undo.compress.enable=true
client.undo.compress.type=zip
client.undo.compress.threshold=64k
log.exceptionRate=100
transport.serialization=seata
transport.compressor=none
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898

大多数参数可以保持默认配置,需要根据环境修改的配置项大致包括:

store.mode=db
store.db.datasource=
store.db.dbType=
store.db.driverClassName=
store.db.url=
store.db.user=
store.db.password=

根据源码包中的脚本,执行脚本,导入配置:

nacos-config.sh -h 127.0.0.1 -p 8848 -g SEATA_GROUP

具体参数根据环境修改。

-h:主机,默认值为localhost。
-p:端口,默认值为8848。
-g:配置分组,默认值为“ SEATA_GROUP”。
-t:租户信息,对应于Nacos的名称空间ID字段,默认值为空。
-u:用户名,权限控制在的nacos 1.2.0+,默认值为空。
-w:密码,权限控制在的nacos 1.2.0+,默认值为空。

随后可以在nacos对应分组中查看到seata相关配置

5.创建seata数据库

在 seata-1.4.2\script\server\db目录下,找到脚本文件,这里选择mysql.sql。

在对应数据库中执行SQL语句创建相关表。

-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,

    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),

) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

-- the table to store BranchSession data

    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,

    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(128),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),
    `table_name`     VARCHAR(32),
    `pk`             VARCHAR(36),
    `gmt_create`     DATETIME,
    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;
  1. 启动seata server

/data/soft/seata/seata-server-1.4.2/bin/seata-server.sh -p 8901 -h 127.0.0.1 -n 1 

seata启动成功日志

出现以上启动日志,则表示启动成功,随后可以去nacos服务列表中查看到seata服务
