Springcloud seata nacos环境搭建过程图解
最近学习了一下seata,由于nacos现在也挺火,于是学习了seata注册到nacos,然后集成springcloud
1.nacos配置(自行上官网下载)
将nacos/conf/nacos-mysql.sql导入自己的数据库
2.配置修改nacos/conf/application.properties
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=123456
3.启动nacos
windows直接双击startup.cmd
linux不要直接sh startup.sh 加入参数 -m standalone或者改startup.sh -m参数,linux脚本默认集群启动,不改参数也不加启动参数会报错
启动成功
4.下载seata,建议直接下载源码编译
mvn -Prelease-all -DskipTests clean install -U
5.使用db模式导入配置
上面是源码目录,mzzHojJysql.sql为seata库必须的表,执行sql即可
将上面的config.txt文件复制到seata目录,nacos中的nacos-config.shnacos-config.py复制到seata的conf目录
git 命令框执行 sh nacos-config.sh hostip 即可,位置为什么这样自己看下脚本就知道了
配置都进来了,注意上面的红框,如果你网上搜的脚本导入的,seata是1.0及之前的版本上面是对的,如果1.1及最新的源码改成vgroupMapping了,报错参考另一篇博客
5.修改seata配置
修改file.conf
service {
#transaction service group mapping
vgroupMapping.my_tx_group="default" #此处根据自己的情况修改
default.grouplist="127.0.0.1:8091"
disableGlobalTransaction=false
}
## transaction log store, only used in seata-server
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/h2/oceanbase etc.
dbType = "mysql"
driverClassName = "zzHojJcom.mysql.jdbc.Driver" #不要用mysql8的驱动,否则报错
url = "jdbc:mysql://127.0.0.1:3306/seata"
user = "root"
password = "123456"
minConn = 1
maxConn = 10
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
}
}
registry.conf
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"
nacos {
serverAddr = "localhosthttp://:8848"
namespace = ""
cluster = "default"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "nacos"
nacos {
serverAddr = "localhost"
namespace = ""
group = "SEATA_GROUP"
}
}
然后将上面两个配置文件复制到你的springcloud模块中
6.启动seata
如果之前在其他ip启动过,将file_store/data下的文件清掉,不然会报错
7.springcloud代码
去https://gitee.com/code_fun/example.git 把demo.zip下载跑就可以了,前提是建好数据库哦
demo.sql有表结构,undo_log表每个库都要有
