sharding-proxy docker 打包部署和测试

1、准备好mysql master/slave 环境。

2、自己打包部署：

自己打包，先下载 apache-shardingsphere-4.1.1-sharding-proxy-bin.tar.gz

curl -O https://archive.apache.org/dist/shardingsphere/4.1.1/apache-shardingsphere-4.1.1-sharding-proxy-bin.tar.gz

解压后，如果连mysq8.0，需把 mysql-connector-java-8.0.15.jar 驱动包拷贝到 lib 下

[Dockfile]
FROM openjdk:8-jre-slim
MAINTAINER summer

RUN ln -sf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
ADD apache-shardingsphere-4.1.1-sharding-proxy-bin /opt/sharding-proxy

ENTRYPOINT ["/bin/sh","-c","/opt/sharding-proxy/bin/start.sh ${PORT} && tail -f /opt/sharding-proxy/logs/stdout.log"]

[Build]
docker build -t summer/sharding-proxy:v1.0.0 .
    
docker run \
    -v /root/dev/sharding-proxy/conf:/opt/sharding-proxy/conf \
    -v /root/dev/sharding-proxy/logs:/opt/sharding-proxy/logs \
    --link mysql-master:mysql-master-host \
    --link mysql-slave0:mysql-slave0-host \
    -e PORT=3306 -p3307:3306 --name sharding-proxy -d summer/sharding-proxy:v1.0.0

2、用官方镜像打包部署

docker pull apache/sharding-proxy:4.1.1

建立 
 /root/dev/sharding-proxy/conf
 /root/dev/sharding-proxy/logs
 /root/dev/sharding-proxy/ext-lib

将 mysql-connector-java-8.0.15.jar 拷贝到 ext-lib


docker run \
    -v /root/dev/sharding-proxy/conf:/opt/sharding-proxy/conf \
    -v /root/dev/sharding-proxy/logs:/opt/sharding-proxy/logs \
    -v /root/dev/sharding-proxy/ext-lib:/opt/sharding-proxy/ext-lib \
    --link mysql-master:mysql-master-host \
    --link mysql-slave0:mysql-slave0-host \
    -e PORT=3306 -p3307:3306 --name apache-sharding-proxy -d apache/sharding-proxy:4.1.1



修改配置文件: 

[server.yaml]
authentication:
  users:
    root:
      password: root
    sharding:
      password: sharding
      authorizedSchemas: sharding_db

props:
  max.connections.size.per.query: 1
  acceptor.size: 16  # The default value is available processors count * 2.
  executor.size: 16  # Infinite by default.


[config-base.yaml]
schemaName: sharding_db

dataSources:
  master_ds:
    url: jdbc:mysql://mysql-master-host:3306/shardingjdbc?serverTimezone=UTC&useSSL=false
    username: base_sa
    password: base_sa
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50
  slave_ds_0:
    url: jdbc:mysql://mysql-slave0-host:3306/shardingjdbc?serverTimezone=UTC&useSSL=false
    username: base_sa
    password: base_sa
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50

masterSlaveRule:
  name: ms_ds
  masterDataSourceName: master_ds
  slaveDataSourceNames:
    - slave_ds_0

如果有报错：
com.mysql.cj.jdbc.MysqlXAException: XAER_RMERR: Fatal error occurred in the transaction branch - check your data for consistency
原因是atomikos 解决分布式事务报错
解决方案：给账号加系统权限
GRANT XA_RECOVER_ADMIN ON *.* TO base_sa@'%' ;

3、测试应用的配置文件

spring:
  main:
    lazy-initialization: false
  jmx:
    enabled: false
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://xxxxxxxxxx:3307/sharding_db?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=GMT%2B8
    username: sharding
    password: sharding
