07、ShardingSphere实战：ShardingSphere-Proxy读写分离部署

shardingSphere-proxy8104 项目

1、修改配置文件

修改配置config-readwrite-splitting.yaml

schemaName: readwrite_splitting_db

dataSources:
  write_ds:
    url: jdbc:mysql://192.168.100.201:3306/db_user?serverTimezone=UTC&useSSL=false
    username: root
    password: 123456
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50
    minPoolSize: 1
  read_ds_0:
    url: jdbc:mysql://192.168.100.201:3307/db_user?serverTimezone=UTC&useSSL=false
    username: root
    password: 123456
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50
    minPoolSize: 1
  read_ds_1:
    url: jdbc:mysql://192.168.100.201:3308/db_user?serverTimezone=UTC&useSSL=false
    username: root
    password: 123456
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50
    minPoolSize: 1

rules:
- !READWRITE_SPLITTING
  dataSources:
    readwrite_ds:
      type: Static
      props:
        write-data-source-name: write_ds
        read-data-source-names: read_ds_0,read_ds_1

将配置文件上传至/atguigu/server/proxy-a/conf目录

重启容器

docker restart server-proxy-a

2、实时查看日志

可以通过这种方式查看服务器中输出的SQL语句

docker exec -it server-proxy-a env LANG=C.UTF-8 /bin/bash
tail -f /opt/shardingsphere-proxy/logs/stdout.log

3、远程访问测试

mysql> show databases;
mysql> use readwrite_splitting_db;
mysql> show tables;
mysql> select * from t_user;
mysql> select * from t_user;
mysql> insert into t_user(uname) values('wang5');
