数据库脚本
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`

一：拉取Seata镜像
docker pull seataio/seata-server:1.4.2
二：运行Seata容器
2.-2. 搭建Nacos Seata命名空间
命名空间名称seata-naming
命名空间ID = d4874eb0-1917-45fd-8dc1-34f6f3f5265a
配置数99 / 200
描述seata 命名空间
2.-1. 运行 Seata容器命令
docker run -d --name seata-server -p 8091:8091 -e SEATA_IP=你的ip seataio/seata-server:1.4.2
2.0. 异常注入-ERROR：客戶端->注意：-e SEATA_IP=你的ip
如果不指向ip,默认注入nacos为seata容器ip 173.开头的，若果不是一个网桥一个ip下面在整合到微服务中会报异常信息
2022-12-26 00:38:58.989 ERROR 23132 --- [eoutChecker_1_1] i.s.c.r.netty.NettyClientChannelManager : 0101 can not connect to 172*****2:8091 cause:can not register RM,err:can not connect to services-server.
2.1. 容器内目录拷贝到宿主机
docker cp seata-server:/seata-server /usr/local/home/docker/seata
2.2. 编辑 registry.conf 和 file.conf
下载地址为zip包

-rw-r--r-- 1 root root 1982 12月 23 03:18 registry.conf
2. 2.1. 编辑注册中心相关文件
vim registry.conf
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa

nacos {
application = "seata-server"

}

}
2.2.2. 编辑Seata存储数据的相关配置文件
vim file.conf;
这里面连接的库就是上面执行脚本的库;
transport {
# tcp udt unix-domain-socket
type = "TCP"
#NIO NATIVE
server = "NIO"
#enable heartbeat
heartbeat = true
# the client batch send request enable

clientSelectorThreadSize = 1
clientWorkerThreadPrefix = "NettyClientWorkerThread"
# netty boss thread size,will not be used for UDT
bossThreadSize = 1
#auto default pin or 8
workerThreadSize = "default"
}
shutdown {
# when destroy server, wait seconds
wait = 3
}
serialization = "seata"
compressor = "none"
}
# service configuration, only used in client side
service {
#transaction service group mapping
vgroupMapping.my_test_tx_group = "default"
default.grouplist = "SEATA-IP.101:8091"
#degrade, current not support
enableDegrade = false
#disable seata
disableGlobalTransaction = false
}
#client transaction configuration, only used in client side
client {
rm {
asyncCommitBufferLimit = 10000
lock {
retryInterval = 10
retryTimes = 30
retryPolicyBranchRollbackOnConflict = true
}
reportRetryCount = 5
tableMetaCheckEnable = false

sqlParserType = druid
}
tm {
commitRetryCount = 5
rollbackRetryCount = 5
}
undo {
dataValidation = true
logSerialization = "jackson"
logTable = "undo_log"
}
log {
exceptionRate = 100
}
}
## transaction log store, only used in server side
store {
## store mode: file、db
mode = "db"
## 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 {
## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
datasource = "dbcp"
## mysql/oracle/h2/oceanbase etc.
dbType = "mysql"
driverClassName = "com.mysql.cj.jdbc.Driver"
url = "jdbc:mysql://MYSQL-IP:3306/seata-config"

password = "123456"
minConn = 1
maxConn = 10
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
}
}
## server configuration, only used in server side
server {
recovery {
#schedule committing retry period in milliseconds
committingRetryPeriod = 1000
#schedule asyn committing retry period in milliseconds
asynCommittingRetryPeriod = 1000
#schedule rollbacking retry period in milliseconds
rollbackingRetryPeriod = 1000
#schedule timeout retry period in milliseconds
timeoutRetryPeriod = 1000
}
undo {
logSaveDays = 7
#schedule delete expired undo_log in milliseconds
logDeletePeriod = 86400000
}
#unit ms,s,m,h,d represents milliseconds, seconds, minutes, hours, days, default permanent
maxCommitRetryTimeout = "-1"
maxRollbackRetryTimeout = "-1"
rollbackRetryTimeoutUnlockEnable = false
}
## metrics configuration, only used in server side
metrics {
enabled = false
registryType = "compact"
# multi exporters use comma divided
exporterList = "prometheus"
exporterPrometheusPort = 9898
}
刚刚修改的是宿主机文件，但需注意即使是挂载目录进入容器相关修改的配置文件也不会生效
2.3. 宿主机文件拷贝至容器内部
docker cp /usr/local/home/docker/seata/seata-server/resources/registry.conf 16920a0fb6a5:/seata-server/resources/registry.conf
docker cp /usr/local/home/docker/seata/seata-server/resources/file.conf 16920a0fb6a5:/seata-server/resources/file.conf
2.4. 配置 nacos-config.sh 和 config.txt
2.4.1. 编辑nacos-config.sh nacos配置文件加载sh执行文件
2.4.1.1 代码如下

可以看到相关输出
2.4.4. 查看Nacos是否载入配置信息

3.2 重启seata服务 - > 看是否注入seata
3.3 没有注入 - > 进入容器查看配置文件
已经生效
[root@master01 resources]# docker exec -it 4d0f7460795d sh
/seata-server # ls
classes libs resources sessionStore
/seata-server # cd resources/
/seata-server/resources # ls
META-INF README.md file.conf.example logback registry.conf
README-zh.md file.conf io logback.xml
/seata-server/resources # vi registry.conf
3.4 重启服务或刷新，在此查看，成功
注意这里ip和运行时 ip指向有关，否则ip为seata容器ip
