SEATA

1. 版本 1.2.0

2. 文档地址：http://seata.io/zh-cn/docs/ops/deploy-by-docker.html

3. 应用 docker 部署 seata

3.1 拉取运行镜像

docker pull seataio/seata-server:1.2.0
docker run -d --name seata-server -p 8091:8091 -d  seataio/seata-server:1.2.0

3.2 应用 docker cp 命令，将容器中的配置文件拷贝进去。

docker cp seata-server:/seata-server/resources ~/seata-script

3.3 进入到 seata-script 文件夹

cd ~/seata-script

3.4 批改 file.conf

vim file.conf

3.5 须要依据本人的环境批改 url，user，password

## transaction log store, only used in seata-server
store {
 ## store mode: file、db
 ## 批改此处为 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"
     ## 批改为本人数据库的 ip、端口和库名
     url = "jdbc:mysql://ip:port/seata_demo"
     ## 批改为本人数据库用户名
     user = "user"
     ## 批改为本人数据库明码
     password = "pass"
     minConn = 5
     maxConn = 30
     globalTable = "global_table"
     branchTable = "branch_table"
     lockTable = "lock_table"
     queryLimit = 100
     maxWait = 5000
 }
}

3.6 批改 registry.conf 文件

vim registry.conf
registry {
         # file、nacos、eureka、redis、zk、consul、etcd3、sofa
         ## 批改为 nacos，前面那些配置只有关注 nacos 就好，其余能够删掉
         type = "nacos"
        ​
         nacos {
             ## 留神，这里其实官网配置文件是有一个坑的，就是 `nacos` 的 `application` 配置，旧值为 seata-server，咱们须要批改为 serverAddr
             application = "seataAddr"
             ## 批改为 Nacos 服务器 ip 地址
             serverAddr = "127.0.0.1"
             ## 批改为 Nacos 给 Seata 用的 Namespace，须要上 Nacos 新建一个
             namespace = "seata"
             cluster = "default"
             ## 批改为 Nacos 的用户名
             username = "nacos"
             ## 批改为 Nacos 的明码
             password = "nacos"
         }
         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
         ## 批改为 nacos
         type = "nacos"
        ​
         ## 批改办法同上
         nacos {
             serverAddr = "127.0.0.1"
             namespace = "seata"
             group = "SEATA_GROUP"
             username = "nacos"
             password = "nacos"
         }
         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"}
        }

3.7 把批改好的配置文件拷贝回 seata 容器

docker cp registry.conf seata-server:/seata-server/resources
docker cp file.conf seata-server:/seata-server/resources

3.8 重启 seata-server 容器

docker restart seata-server

如果启动胜利会在 nacos 上看到这个服务

3.9 通过脚本把配置传到 nacos

3.9.1 下载源码：https://github.com/seata/seata/tree/1.2.0
3.9.2 用 idea 关上
3.9.3 定位到截图地位，并批改 /script/config-center/config.txt 配置

transport.heartbeat=true
transport.enableClientBatchSendRequest=false
transport.threadFactory.bossThreadPrefix=NettyBoss

transport.threadFactory.clientSelectorThreadSize=1
transport.threadFactory.clientWorkerThreadPrefix=NettyClientWorkerThread
transport.threadFactory.bossThreadSize=1
transport.threadFactory.workerThreadSize=default
transport.shutdown.wait=3
## 所有须要用到 Seata 的微服务名，须要跟微服务中 Seata 的配置统一

3.9.4 idea 执行 nacos-config.sh 脚本，86 行改为 config.txt 的门路
 for line in $(cat ../config.txt | sed s/[[:space:]]//g); do

3.9.5 idea terminal 运行，如果运行胜利 terminal 会打印出所有配置，并在 nacos 上 seata 对应的 namespace 也能看到这些配置
bash nacos-config.sh -h nacos 的 ip -p nacos 的端口 -g nacos 上 seata 的 group -t nacos 上 seata 的 namespace
## 例如
bash nacos-config.sh -h 127.0.0.1 -p 8848 -g seata -t SEATA_GROUP
