docker-informix实践

Answer

基于Debian/Ubuntu 的docker container with IBM Informix Dynamic Server。

Informix数据库服务器提供的版本,包括免费的开发者版本,为小型和中型企业版本,版本支持完整的特性集和最大的设计用于支持企业应用程序。如果你对选用哪个版本的Informix感到困惑，请参见Informix12.1不同版本的特性描述。

Informix通常被认为是低成本高优化零管理的高效易用数据库,包括用作嵌入式数据库。它具有稳定性高，长时间的维持很高的事务支持率等等。因此，Informix被广泛部署在零售业,在店内的低管理开销很有用的部署。

建立Informix container image (Ubuntu host)

## 去除标准的Ubuntu Docker 安装

sudo apt-get purge docker.io
curl -s https://get.docker.io/ubuntu/ | sudo sh

## 生成 enviroment for docker-informix container build
mkdir informix_build
cd informix_build
git clone https://github.com/0x1fff/docker-informix.git

## 下载IBM Informix 安装文件并完成拷贝
cp iif.*.linux-x86_64.tar .

## 启动 HTTP server with Informix image
python -m SimpleHTTPServer 9090 &
PY_HTTP=$!

## Build docker image (Dockerfile may require minor changes)
sudo docker build -t docker-informix docker-informix

## Shutdown HTTP server
kill $PY_HTTP

启动 Informix container (Ubuntu host)

在端口90088上部署Informix

sudo docker run -it -v "/home/informix/data/" -p 9088:9088 --name informix docker-informix

生成一个空的database： "test"

sudo docker run -it -v "/home/informix/data/" -p 9088:9088 --name informix -e DB_USER=test -e DB_PASS=test -e DB_NAME=test docker-informix

创建container (Informix Database)

johny@ThinkPad:~/$ docker ps -a

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
00e73b00c498 docker-informix:latest "/bin/bash" About an hour ago Exited (0) 6 seconds ago informix

johny@ThinkPad:~/$ docker start 00e73b00c498
00e73b00c498

johny@ThinkPad:~/$ docker attach 00e73b00c498

连接Informix数据库

对于连接到Informix数据库可以使用SQLWorkbench / J与额外的Informix JDBC驱动程序的包或单独从IBM Informix JDBC驱动程序下载页面下载 IBM Informix JDBC Driver Download Page .

JDBC连接串如下：

jdbc:informix-sqli://127.0.0.1:9088/test:INFORMIXSERVER=dev;user=test;password=test;CLIENT_LOCALE=en_US.utf8;DB_LOCALE=en_US.utf8

对于Docker (仅对于x86_64版本)可用的informix版本如下：

· 12.10FC4TL - Informix Enterprise Time-Limited Edition for Linux x86_64 (iif.12.10.FC4TL.linux-x86_64.tar)

· 12.10FC4DE - Informix Developer Edition for Linux x86_64 (iif.12.10.FC4DE.linux-x86_64.tar)

· 12.10FC4IE - Informix Innovator-C Edition for Linux x86_64 (iif.12.10.FC4IE.linux-x86_64.tar)

· 11.70FC8DE - Informix Developer Edition for Linux x86_64 (iif.11.70.FC8DE.linux-x86_64.tar)

· 11.70FC8IE - Informix Innovator-C Edition for Linux x86_64 (iif.11.70.FC8IE.linux-x86_64.tar)

· 11.50FC9DE - Informix Developer Edition for Linux x86_64 (iif.11.50.FC9DE.linux-x86_64.tar)

Informix Version (x86_64)	Ubuntu 14.10	Ubuntu 14.04	Debian 7 (wheezy)
12.10.FC4 Time Limited
12.10.FC4 Innovator Edition
12.10.FC4 Developer Edition
11.70.FC8 Developer Edition
11.70.FC8 Innovator Edition
11.70.FC8 Time Limited

图例:

· - Installation completed succesfully

· - Instalation failed

· - Notes

附加说明:

1. 需Informix 11.70 以上版本.

2. Informix 安装测试限于 Debian 7 Wheezy 及 Ubuntu 14.04 LTS+ OS.

3. 虽然Informix在Ubuntu 13.10, Ubuntu 12.04 运行得都不错，但测试建议还是Ubuntu 14.04支持到位。.

4. 假如您使用的是Informix 11.50版本，将不可用。
