docker安装db2

这里是单机安装，直接安装db2express-c，介绍网址 : libmcom / db2express-c

    docker search db2express-c
-p 50000:50000 允许远程的客户端可以从50000 端口连接到数据库实例.
通过指定 -e DB2INST1_PASSWORD=db2root-pwd 参数, 你可以为缺省的Db2实例用户db2inst1设置密码.注意：这里“DB2INST1”是用户名，而“b2root-pwd”是密码。
通过指定-e LICENSE=accept参数, 表示你接受了使用Db2软件的许可证协议.
有教程说要添加 --network=host ，我在添加后各种莫名的报错╮(╯▽╰)╭
4、切换用户并运行DB2
    $ su - db2inst1     //切换用户
    $ db2start          //启动DB2
    $ db2sampl          //创建默认数据库“SAMPLE”
5、常用命令
    db2 create db [dbname] #创建数据库 
    db2 list db directory #列出所有数据库 
    db2 list active databases #列出所有激活的数据库 
    db2 get db cfg #列出所有数据库配置

[db2inst1@connections ~]$ db2 update dbm cfg using SVCENAME 50000
