一、环境部署
1、在自己的数据库新建seata数据库
2、利用seata官方提供的seata数据库sql脚本创建所需数据库seata以及表,脚本地址如下:
seata/mysql.sql at 1.4.1 · seata/seata · GitHub
3、查看docker官方镜像仓库版本
4、拉取seata安装镜像
docker pull seataio/seata-server:1.6.0
我这里拉取的是1.6.0版本的。
5、创建/seata目录
mkdir /seata
6、在seata目录下创建conf目录
mkdir conf
如图
7、创建file.conf文件并编辑
touch file.conf
然后
vim file.conf
##transaction log store, only used in seata-server
store {
## store mode: file、db、redis
mode = "db" ## 默认是file
## file store property
file {
## store location dir
dir = "sessionStore"
# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
maxBranchSessionSize = 16384
# globe session size , if exceeded throws exceptions
maxGlobalSessionSize = 512
# file buffer size , if exceeded allocate new buffer
fileWriteBufferCacheSize = 16384
# when recover batch read size
sessionReloadReadSize = 100
# async, sync
flushDiskMode = async
}
##database store property
db {
datasource = "druid"
## mysql/oracle/postgresql/h2/oceanbase etc.
dbType = "mysql"
driverClassName = "com.mysql.cj.jdbc.Driver"
url = "jdbc:mysql://数据库地址:端口/seata?serverTimezone=GMT%2B8"
user = "数据库名字"
password = "数据库密码"
minConn = 5
maxConn = 30
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
maxWait = 5000
}
保存并退出
:wq!
8、创建registry.conf文件并编辑
touch registry.conf
并编辑
vim registry.conf
##transaction log store, only used in seata-server
store {
## store mode: file、db、redis
mode = "db" ## 默认是file
## file store property
file {
## store location dir
dir = "sessionStore"
maxBranchSessionSize = 16384
# globe session size , if exceeded throws exceptions
maxGlobalSessionSize = 512
# file buffer size , if exceeded allocate new buffer
fileWriteBufferCacheSize = 16384
# when recover batch read size
}
}
#服务,将type从file改成nacos,将seata服务配置进nacos
registry {
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "ip:8848"
group = "SEATA_GROUP"
namespace = "seata_namespace"
cluster = "default"
username = "用户名"
password = "密码"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "file"
nacos {
serverAddr = "ip:8848"
namespace = "seata_namespace"
group = "SEATA_GROUP"
cluster = "default"
username = "用户名"
password = "密码"
}
file {
name = "file.conf"
}
}
保存并退出
:wq!
9、在seata目录下创建config.txt配置文件
touch config.txt
&
vim comfig.txt
transport.type=TCP
transport.server=NIO
transport.heartbeat=true
transport.enableClientBatchSendRequest=false
transport.threadFactory.bossThreadPrefix=NettyBoss
transport.threadFactory.workerThreadPrefix=NettyServerNIOWorker
transport.threadFactory.serverExecutorThreadPrefix=NettyServerBizHandler

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.sqlParserType=druid
client.rm.reportSuccessEnable=false
client.rm.sagaBranchRegisterEnable=false
client.tm.commitRetryCount=5
client.tm.rollbackRetryCount=5
client.tm.degradeCheck=false
client.tm.degradeCheckAllowTimes=10
client.tm.degradeCheckPeriod=2000
store.mode=db
store.file.dir=seata/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.cj.jdbc.Driver
store.db.url=jdbc:mysql://数据库链接地址:端口/seata?useUnicode=true
store.db.user=用户名
store.db.password=密码
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.host=127.0.0.1
store.redis.port=6379
store.redis.maxConn=10
store.redis.minConn=1
store.redis.database=0
store.redis.password=null
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.log.exceptionRate=100
transport.serialization=seata
transport.compressor=none
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898
10、创建并编辑nacos-config.sh文件
touch nacos-config.sh
&
vim nacos-config.sh
#!/usr/bin/env bash
while getopts ":h:p:g:t:u:w:" opt
do
case $opt in
h)
host=$OPTARG
;;
p)
port=$OPTARG
;;
g)
group=$OPTARG
;;
t)
tenant=$OPTARG
;;
u)
username=$OPTARG
;;
w)
password=$OPTARG
;;
?)
echo " USAGE OPTION: $0 [-h host] [-p port] [-g group] [-t tenant] [-u username] [-w password] "
exit 1
;;
esac
done
if [[ -z ${host} ]]; then
host=localhost
fi
if [[ -z ${port} ]]; then
port=8848
fi
if [[ -z ${group} ]]; then
group="SEATA_GROUP"
fi
if [[ -z ${tenant} ]]; then
tenant=""
fi
if [[ -z ${username} ]]; then
username=""
fi
if [[ -z ${password} ]]; then
password=""
fi
nacosAddr=$host:$port
contentType="content-type:application/json;charset=UTF-8"
echo "set nacosAddr=$nacosAddr"
echo "set group=$group"
failCount=0
tempLog=$(mktemp -u)
function addConfig() {
curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$1&group=$group&content=$2&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/null
if [[ -z $(cat "${tempLog}") ]]; then
echo " Please check the cluster status. "
exit 1
fi
if [[ $(cat "${tempLog}") =~ "true" ]]; then
echo "Set $1=$2 successfully "
else
echo "Set $1=$2 failure "
(( failCount++ ))
fi
}
count=0
for line in $(cat $(dirname "$PWD")/config.txt | sed s/[[:space:]]//g); do
(( count++ ))
key=${line%%=*}
value=${line#*=}
addConfig "${key}" "${value}"
done
echo "========================================================================="
echo " Complete initialization parameters, total-count:$count , failure-count:$failCount "
echo "========================================================================="
if [[ ${failCount} -eq 0 ]]; then
echo " Init nacos config finished, please start seata-server. "
else
echo " init nacos config fail. "
fi
注意:config.txt与nacos-config.sh文件不能在同一个目录下,否则执行不了。本文config.txt文件放在seata目录下,nacos-config.sh在seata/bin目录下
11、进入bin目录运行nacos-config.sh文件
sh nacos-config.sh -h 127.0.0.1 -p 8848 -g SEATA_GROUP -t seata_namespace_id -u nacos -w nacos
上面的ip换成自己实际的nacos服务器ip, nacos的账户密码按实际替换,回车执行,完成后会在nacos指定namespace下创建对应配置。如图:
看到上面的的列表表示执行成功
12、启动seata
docker run -d --name seata-server --restart=always -h 120.79.32.155 -p 8091:8091 -e SEATA_IP=120.79.32.155 -v /seata/conf/registry.conf:/seata-server/resources/registry.conf -v /seata/logs:/root/logs seataio/seata-server:1.6.0
13、seata注册到nacos
13.1、从运行的seata镜像中复制文件到seata目录下进行修改
docker cp seata-server:/seata-server/resources/application.yml /seata
13.2、编辑application.yml文件
vim application.yml
config: classpath:logback-spring.xml
file:
path: ${user.home}/logs/seata
extend:
logstash-appender:
destination: 127.0.0.1:4560
kafka-appender:
bootstrap-servers: 127.0.0.1:9092
topic: logback_to_logstash
console:
user:
username: seata
password: seata
seata:
config:
# support: nacos, consul, apollo, zk, etcd3
type: nacos
nacos:
application: seata-server
server-addr: 120.79.32.155:8848
namespace: seata_namespace
group: SEATA_GROUP
username: dekun_dev_test
password: dk_Etms_Mg
registry:

nacos:
application: seata-server

group: SEATA_GROUP

password: dk_Etms_Mg
# store:
# support: file 、 db 、 redis
# mode: file
# server:
# service-port: 8091 #If not configured, the default is '${server.port} + 1000'
security:
secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
tokenValidityInMilliseconds: 1800000
ignore:
urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login
编辑完成后复制回docker部署的seata容器中
docker cp application.yml seata-server:/seata-server/resources
重启seata
docker restart 容器id
二、项目应用
1、配置bootstrap.yml
seata:
enabled: true
enable-auto-data-source-proxy: false
tx-service-group: dekun_my_gyl_group
service:
disable-global-transaction: false
vgroup-mapping:
dekun_my_gyl_group: default
# grouplist:
# default: ip:8091
registry:
type: nacos
nacos:
application: seata-server
server-addr: ip:8848
namespace: seata_namespace
group: SEATA_GROUP
username: dekun_dev_test
password: dk_Etms_Mg
# 可选 默认
cluster: default
config:
nacos:
application: seata-server
server-addr: ip:8848
namespace: seata_namespace
group: SEATA_GROUP
username: dekun_dev_test
password: dk_Etms_Mg
# client:
# rm:
# report-success-enable: false
启动成功
