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.reportSuccessEnable=false
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,
`application_id` VARCHAR(32),
`transaction_service_group` VARCHAR(32),
`transaction_name` VARCHAR(128),
`timeout` INT,
`begin_time` BIGINT,
`application_data` VARCHAR(2000),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`xid`),
KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
`branch_id` BIGINT NOT NULL,
`xid` VARCHAR(128) NOT NULL,
`transaction_id` BIGINT,
`resource_group_id` VARCHAR(32),
`resource_id` VARCHAR(256),
`branch_type` VARCHAR(8),
`status` TINYINT,
`client_id` VARCHAR(64),
`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;
/data/soft/seata/seata-server-1.4.2/bin/seata-server.sh -p 8901 -h 127.0.0.1 -n 1
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
