通过 Docker 实现国产数据库 OpenGauss 开发环境搭建

通过 Docker 实现国产数据库 OpenGauss 开发环境搭建

一 前置准备

2.1 下载镜像

docker pull enmotech/opengauss:5.0.1

构建镜像的 Dockerfile，方便后期实现个性化定制：

2.2 环境变量配置说明

GS_PASSWORD：必须设置该参数。该参数值不能为空或者不定义。该参数设置了 openGauss 数据库的超级用户 omm 以及测试用户 gaussdb 的密码。openGauss 安装时默认会创建 omm 超级用户，该用户名暂时无法修改。测试用户 gaussdb 是在 entrypoint.sh 中自定义创建的用户。openGauss 镜像配置了本地信任机制，因此在容器内连接数据库无需密码，但是如果要从容器外部（其它主机或者其它容器）连接则必须要输入密码。openGauss 的密码有复杂度要求，需要：密码长度 8 个字符及以上，必须同时包含英文字母大小写，数字，以及特殊符号。

GS_NODENAME：指定数据库节点名称 默认为 gaussdb。

GS_USERNAME：指定数据库连接用户名 默认为 gaussdb。

GS_PORT：指定数据库端口，默认为 5432。

2.3 启动容器

启动命令如下：

docker run -d --name opengauss \--privileged=true \--restart=always \-v /home/ivan/data/opengauss:/var/lib/opengauss  \-u root \-p 15432:5432 \-e GS_NODENAME=gaussdb \-e GS_USERNAME=gaussdb \-e GS_PASSWORD='C*x#1a2b' \enmotech/opengauss:5.0.1

2.4 使用 gsql 连接数据库

示例如下：

gsql -d "host=127.0.0.1 port=5432 dbname=gaussdb user=omm password='C*x#1a2b'"

2.5 建库建表

示例如下：

CREATE USER IF NOT EXISTS cmams WITH PASSWORD 'ghaF&fZugC9y';
CREATE DATABASE IF NOT EXISTS cmams ENCODING 'UTF8' OWNER cmams;
CREATE SCHEMA IF NOT EXISTS cmams;
GRANT CREATE,USAGE ON SCHEMA cmams TO cmams;
GRANT SELECT,INSERT,UPDATE,DELETE ON ALL TABLES IN SCHEMA public TO cmams;
GRANT USAGE,SELECT ON ALL SEQUENCES IN SCHEMA cmams TO cmams;
DROP TABLE IF EXISTS cmams.cmams_status;
CREATE TABLE cmams_status
(cmams_id               varchar(18) not null constraint cmams_status_pk primary key,cmams_province         varchar(20) not null,cmams_concurrency      integer   not null,cmams_successful_count integer   not null,cmams_failure_count    integer   not null,cmams_queue_length     integer   not null,cmams_update_time      timestamp   not null
);COMMENT ON COLUMN cmams_status.cmams_id IS '主键ID';
COMMENT ON COLUMN cmams_status.cmams_province IS '省份';
COMMENT ON COLUMN cmams_status.cmams_concurrency IS '当前并发数';
COMMENT ON COLUMN cmams_status.cmams_successful_count IS '成功调用次数';
COMMENT ON COLUMN cmams_status.cmams_failure_count IS '调用失败次数';
COMMENT ON COLUMN cmams_status.cmams_queue_length IS 'Redis队列长度';
COMMENT ON COLUMN cmams_status.cmams_update_time IS '数据更新时间';
