Docker 搭建 GBase 8s数据库服务

1，Docker服务已经创建 2，足够的空间（GBase 8s For Docker最少需要2G的空间及1G以上的内存）

具体步骤

1，查找GBase 8s 镜像版本

[root@localhost ~]# docker search gbase8s
NAME                DESCRIPTION             STARS               OFFICIAL            AUTOMATED
liaosnet/gbase8s    GBase8sV8.7_2.0.1a2_2   1                                       

2，拉取GBase 8s镜像

[root@localhost ~]# docker pull liaosnet/gbase8s:2.0.1a2_2
2.0.1a2_2: Pulling from liaosnet/gbase8s
9b4ebb48de8d: Pull complete 
feabbffc73e8: Pull complete 
b361dbaead54: Pull complete 
c84f88b6f6bf: Pull complete 
Digest: sha256:5e84d1b00de967a033facb115d4c3630fcd931b2fb68820eb4662fb52d8f1153
Status: Downloaded newer image for liaosnet/gbase8s:2.0.1a2_2
docker.io/liaosnet/gbase8s:2.0.1a2_2

拉取时间可能会有些长，记得配置使用国内镜像。

3，查看本地镜像

[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
liaosnet/gbase8s    2.0.1a2_2           d8f4c547d6ae        10 days ago         986MB

上面可以看到我们已经安装了最新版本2.0.1a2_2版本的GBase 8s镜像。

4，运行容器

[root@localhost ~]# docker run -itd -p 19088:9088 liaosnet/gbase8s:2.0.1a2_2

参数说明：

-p 19088:9088：映射容器服务的 9088端口到宿主机的 19088端口，外部主机可以直接通过 宿主机ip:19088访问到 GBase 8s的服务。

5，安装成功

通过docker ps 命令查看安装是否成功

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                     NAMES
194b078358cc        liaosnet/gbase8s:2.0.1a2_2   "/bin/sh -c 'su - gb…"   5 seconds ago       Up 3 seconds        0.0.0.0:19088->9088/tcp   strange_poincare

进入容器，查看数据库状态

[root@localhost ~]# docker exec -it 194b078358cc bash
[root@194b078358cc /]# su - gbasedbt
[gbasedbt@194b078358cc ~]$ onstat -g ntt
