借本地虚机环境安装 ShardingSphere-Proxy 5.2.1 机会,记录了安装过程,供大家参考。

ShardingSphere 支持多种安装方式,如通过二进制包、使用 Docker使用 Helm。本文档介绍如何通过二进制包快速构建 ShardingSphere-Proxy 测试环境,使用版本为 5.2.1。更详细的安装说明,请参考用户手册:使用二进制发布包安装 ShardingSphere-Proxy。

环境要求

  • 操作系统:Linux,Windows
  • Java JRE:8 或以上版本

安装 ShardingSphere-Proxy

通过 5 个步骤完成快速安装:

  1. 下载产品包
  2. 解压产品包
  3. 修改配置文件(server.yaml)
  4. 引入数据库驱动
  5. 启动服务

环境信息如下:

  • 配置:1c/2g
  • 操作系统:CentOS 7.6
  • Java:1.8.0

下载产品包

可通过 wget 方式直接下载到测试机,或点此下载 apache-shardingsphere-5.2.1-shardingsphere-proxy-bin.tar.gz 软件包后,手动上传至测试机。

# cd /opt
# wget https://archive.apache.org/dist/shardingsphere/5.2.1/apache-shardingsphere-5.2.1-shardingsphere-proxy-bin.tar.gz

解压产品包

# pwd 
/opt
# tar xf apache-shardingsphere-5.2.1-shardingsphere-proxy-bin.tar.gz
# cd apache-shardingsphere-5.2.1-shardingsphere-proxy-bin 
# ls
LICENSE  NOTICE  README.txt  bin  conf  lib  licenses

修改配置文件(server.yaml)

先对初始配置文件拷贝备份。

# pwd
/opt/apache-shardingsphere-5.2.1-shardingsphere-proxy-bin
# cp ./conf/server.yaml ./conf/server.yaml.bak

默认的配置文件将不能被直接使用,需要对运行模式权限配置进行修改。

# pwd
/opt/apache-shardingsphere-5.2.1-shardingsphere-proxy-bin
# vi ./conf/server.yaml
--可将如下内容追加至 server.yaml 末尾

mode:
  type: Standalone
  repository:
    type: JDBC

rules:
  - !AUTHORITY
    users:
      - root@%:root
      - sharding@:sharding
    provider:
      type: ALL_PERMITTED

引入数据库驱动(可选)

ShardingSphere 产品包内包含了 PostgreSQL 和 openGauss 数据库驱动。如需引入其他数据库驱动,如 MySQL,则需要单独处理。

# pwd
/opt/apache-shardingsphere-5.2.1-shardingsphere-proxy-bin
# mkdir ext-lib
# wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.11/mysql-connector-java-8.0.11.jar -P ./ext-lib/
# ls ext-lib/
mysql-connector-java-8.0.11.jar

启动服务

通过 bin 目录下的启动脚本启动服务。

# pwd
/opt/apache-shardingsphere-5.2.1-shardingsphere-proxy-bin
# ls ./bin
start.bat  start.sh  stop.sh

# ./bin/start.sh

# tail -100f ./logs/stdout.log
[INFO ] 2022-11-12 16:13:16.307 [main] o.a.s.d.p.c.l.PipelineContextManagerLifecycleListener - mode type is not Cluster, mode type='Standalone', ignore
[INFO ] 2022-11-12 16:13:16.797 [main] o.a.s.p.frontend.ShardingSphereProxy - ShardingSphere-Proxy Standalone mode started successfully

启动成功后,查看服务对应的进程信息。

# ps -ef|grep shardingsphere|grep -v grep

使用数据库客户端访问

# mysql -uroot -p -h127.0.0.1 -P3307

启动与关闭

ShardingSphere-Proxy 服务启动和关闭的脚本位于 ./bin 路径下。

启动

使用以下脚本启动后,服务端口为 ShardingSphere-Proxy 的 3307 缺省端口。

./bin/start.sh

关闭

./bin/stop.sh

总结

ShardingSphere-Prxoy 安装过程比较简单,准备好 Java 环境,获取安装包、解包、修改配置文件后即可启动服务。如果对接的数据库是 MySQL,建议在启动服务前引入 MySQL 驱动,否则需在重启服务后可识别驱动。
