本次采用，将容器的文件复制到容器外，在容器外修改完成后，再复制进去。这里要修改的文件有：registry.conf和file.conf。
在mysql5.7数据库中创建一个名称为seata的数据库，脚本可以在Seata的GitHub地址获取，找到https://github.com/seata/seata/blob/162f83ea851edff801bcdeb3f9ecd018db7e284d/script/server/db/mysql.sql文件，在seata数据库里执行SQL完成初始化操作
docker pull seataio/seata-server:1.2.0 # 下载seata-server 1.2.0的镜像
docker run -d -h 192.168.100.132 -p 8091:8091 seataio/seata-server:1.2.0
在usr/local 下创建文件夹seata
docker cp c02504e4eb14:/seata-server/resources/file.conf /usr/local/seata/file.conf #拷贝容器内文件file.conf到容器外的/usr/local/seata径下
docker cp c02504e4eb14:/seata-server/resources/registry.conf /usr/local/seata/registry.conf #拷贝容器内文件registry.conf到容器外的/usr/local/seata径下
vim file.conf 修改模式为db 修改数据库连接信息
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 = "druid"
## mysql/oracle/postgresql/h2/oceanbase etc.
dbType = "mysql"
driverClassName = "com.mysql.jdbc.Driver"
url = "jdbc:mysql://192.168.100.132:3306/seata"
user = "root"
password = "123456"
minConn = 5
maxConn = 30
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
maxWait = 5000
}
}
vim registry.conf 将seata 注册进nacos中
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "192.168.100.132:80"
namespace = ""
cluster = "default"
username = ""
password = ""
}
eureka {
serviceUrl = "http://localhost:8761/eureka"
application = "default"
weight = "1"
}
redis {
serverAddr = "localhost:6379"
db = 0
password = ""
cluster = "default"
timeout = 0
}
zk {
cluster = "default"
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
}
consul {
cluster = "default"
serverAddr = "127.0.0.1:8500"
}
etcd3 {
cluster = "default"
serverAddr = "http://localhost:2379"
}
sofa {
serverAddr = "127.0.0.1:9603"
application = "default"
region = "DEFAULT_ZONE"
datacenter = "DefaultDataCenter"
cluster = "default"
group = "SEATA_GROUP"
addressWaitTime = "3000"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "file"
nacos {
serverAddr = "localhost"
namespace = ""
group = "SEATA_GROUP"
username = ""
password = ""
}
consul {
serverAddr = "127.0.0.1:8500"
}
apollo {
appId = "seata-server"
apolloMeta = "http://192.168.1.204:8801"
namespace = "application"
}
zk {
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
}
etcd3 {
serverAddr = "http://localhost:2379"
}
file {
name = "file.conf"
}
}
配置文件已经修改完了，我们将文件再复制到容器里面。
docker cp file.conf c02504e4eb14:/seata-server/resources/file.conf
docker cp registry.conf c02504e4eb14:/seata-server/resources/registry.conf
重启容器
docker restart c02504e4eb14
查看启动日志 看有没有报错
docker logs -f c02504e4eb14
查看nacos服务列表 注册成功
