Docker安装配置Seata-Server
1 部署
官方文档指引
1.1 client
每个业务数据库都要新建 undo_log 表。
对 springboot 应用,执行 client - MySQL - AT,切tag=1.5.2:
https://github.com/seata/seata/blob/v1.5.2/script/client/at/db/mysql.sql
1.2 server
新建 seata-for-hire 数据库,执行 server - MySQL:
https://github.com/seata/seata/blob/v1.5.2/script/server/db/mysql.sql
2 Docker
拉取镜像:
$ docker pull seataio/seata-server:1.5.2

拷贝命令:
3 启动容器
$ docker run --name seata-server \
-p 8091:8091 \
-d seataio/seata-server:1.5.2

4 配置
进入容器内部看配置文件:
$ docker exec -it seata-server sh
/seata-server # ls -l
total 16
drwxr-xr-x 6 root root 4096 Jan 1 1970 classes
drwxr-xr-x 1 root root 4096 Jan 1 1970 libs
drwxr-xr-x 6 root root 4096 Jan 1 1970 resources
drwxr-xr-x 2 root root 4096 Jun 20 07:07 sessionStore
/seata-server # cd resources/
/seata-server/resources # ls -l
total 44
drwxr-xr-x 3 root root 4096 Jan 1 1970 META-INF
-rw-r--r-- 1 root root 4471 Jan 1 1970 application.example.yml
-rw-r--r-- 1 root root 960 Jan 1 1970 application.yml
-rw-r--r-- 1 root root 2602 Jan 1 1970 logback-spring.xml
application.yml,要挂载它。退出容器,将刚才那个配置文件复制到宿主机:
$ docker cp seata-server:/seata-server/resources /Users/javaedge/Downloads/soft/seata/
Successfully copied 64.5kB to /Users/javaedge/Downloads/soft/seata/
这就复制到我的宿主机了:

rewriteBatchedStatements
默认 false。无论 'allowMultiQueries' 设置如何,驱动是否应使用多查询,以及在调用 'executeBatch()' 时,是否应对 INSERT 和 REPLACE 类型的预备语句进行改写,把它们变为多值子句语句?
如果使用的是非预处理的简单声明,并且没有对输入数据进行妥善清理,这可能导致 SQL 注入。此外,对预备语句,如在使用 'PreparedStatement.set*Stream()' 时没有指定流长度,驱动将无法确定每批次的最优参数数量,并可能报错说生成的数据包过大。 对于仅包括 INSERT 或 REPLACE 语句的批次重写,'Statement.getGeneratedKeys()' 方法才有效果。
当同时用 "rewriteBatchedStatements=true"、"INSERT ... ON DUPLICATE KEY UPDATE" 对语句改写时,服务器对批量操作中所有受影响(或已找到)的行只会返回一个统一值,并且无法将之正确映射回最初的语句。此时,如果批量操作的总计数为零,驱动会为每一个批量语句返回 "0";如果总计数大于零,则返回 'Statement.SUCCESS_NO_INFO'。

外部的配置文件修改完毕后,还要挂载,需要重建容器:
javaedge@JavaEdgedeMac-mini resources % docker stop seata-server
seata-server
javaedge@JavaEdgedeMac-mini resources % docker rm seata-server
seata-server
启动容器:
javaedge@JavaEdgedeMac-mini resources % docker run --name seata-server \
-p 8091:8091 \
-p 7091:7091 \
-v /Users/javaedge/Downloads/soft/seata/resources://seata-server/resources \
-d seataio/seata-server:1.5.2
