最近接到一个“动态报表”需求:需要动态配置各种数据库的连接,然后查找到指定数据返回。这时候测试数据库就很麻烦了,需要各种类的数据库进行测试。感恩docker,这一切容易了很多很多。
准备环境:
1.系统:centos7.6
2.硬盘:40G (数据库占用内存特别的大)
3.内存:3G (可能同时运行着很多的数据库)
1. 搭建docker 环境 及 相关依赖
#1. 基本配置
// 拉取docker
// 网络拉取
// 编辑器
// 文件导入导出
// 压缩文件
yum install -y docker
yum install -y wget
yum install -y vim
yum install -y lszrz
yum install -y unzip zip
PS:可能出现的异常
【转载】Docker 安装后 报 Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? 解决办法
解决办法
systemctl daemon-reload
sudo service docker restart
sudo service docker status
#2.配置docker 阿里镜像
PS:不配置可能之后等哭了(镜像地址好像要个人账号申请,就不公开了)
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["XXXXX"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
#3. 安装docker-compose
// 输入命令行
// 配置权限
// 查看版本
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
上面完成了基本配置,下面开始进行数据库的安装。
如果已经有镜像,可以直接导入
(本例子中所用的镜像https://pan.baidu.com/s/1tNJ1RL5mpdGmBmP2ciu1Ow 提取码:7p69)
docker load < db2.tar
docker load < mssql-server-linux.tar

2. docker-compose 构建数据库
MySQL
version: '2'
services:
mysql01:
image: docker.io/mysql:5.7
container_name: mysql01
privileged: true
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=Root123456
volumes:
- /home/mysql/logs:/logs
- /home/mysql/conf:/etc/mysql/conf.d

连接参数:
username:root
password:Root123456
port:3306
MSSQL
services:
mssql01:

连接参数:
username:sa
password:Root123456
port:1433
Oracle11g
version: '2'
services:
oracle01:
image: oracleinanutshell/oracle-xe-11g
container_name: oracle01
privileged: true
restart: always
# shm_size: "1g"
ports:
- "1521:1521"
- "8090:8080"
# environment:
# - ORACLE_PWD=root123456
volumes:
- /home/oracle/oradata:/u01/app/oracle/product/11.2.0/xe/oradata
连接参数:
username:system

container_name: oracle02
privileged: true
restart: always
# shm_size: "1g"
ports:
- "1522:1521"
- "8091:8080"
# environment:
# - ORACLE_PWD=root123456
# volumes:
# - /home/oracle/oradata:/u01/app/oracle/oradata
连接参数:
username:system
password:oracle
port:1522
sid:xe
DB2
version: '2'
services:
db2_01:
image: docker.io/ibmcom/db2
container_name: db2_01
privileged: true
ports:
- "50000:50000"
environment:
- DB2INST1_PASSWORD=Root123456

- DBNAME=testdb
volumes:
- /home/db2/database:/database
连接参数:
database:testdb
username:db2inst1
password:Root123456
port:50000
postgres
version: '2'
services:
psql01:
image: docker.io/postgres:9.6
container_name: psql01
privileged: true
ports:
- "5432:5432"
environment:
- POSTGRES_PASSWORD=Root123456
volumes:
- /home/pgsql/database/:/var/lib/postgresql/data
连接参数:
database:postgres
username:postgres
password:Root123456
port:5432
3. 相关的jdbc依赖
对于上面这些数据库,肯定需要对相关的jdbc进行操作,下面是常用的相关 jdbc jar 依赖:
DB2
<dependency>
<groupId>com.ibm.db2.jcc</groupId>
<artifactId>db2jcc</artifactId>
<version>db2jcc4</version>
</dependency>
Oracle 11g 12c
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3</version>
</dependency>
MSSQL
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>11.2.0.3</version>
</dependency>
PgSQL
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.8</version>
</dependency>
MySQL
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
相关的url:
"mysql", "jdbc:mysql://${host}:${port}/${dbName}?characterEncoding=utf8&serverTimezone=UTC"
"oracle", "jdbc:oracle:thin:@${host}:${port}:XE";
"mssql", "jdbc:sqlserver://${host}:${port};${dbName}";
"postgresql", "jdbc:postgresql://${host}:${port}/${dbName}";
"db2", "jdbc:db2://${host}:${port}/${dbName}";
以上就基本描述完环境的搭建
