先决条件

设置T2.Medium类型的EC2实例
ubuntu 20.04 lts as ami
硬盘空间的30 GB
SSH打开端口22，DB2
创建一个IBM帐户，用于下载Db2 community edition

安装

登录到您的EC2实例并验证发行版本

$ ssh -i ibm-db2.pem ubuntu@54.234.180.34

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.6 LTS
Release:        20.04
Codename:       focalDownload and extract Db2 community edition tarball on EC2 instance
You can download the community edition from this URL

在您的本地计算机上下载最新的IBM DB2 Linux（X64）版本
下载完成后，将下载的文件复制到您的EC2实例

$ scp -i ibm-db2.pem v11.5.8_linuxx64_server_dec.tar.gz ubuntu@54.234.180.34:/home/ubuntu

$ pwd
/home/ubuntu

$ ls
v11.5.8_linuxx64_server_dec.tar.gz

$ tar -xzvf v11.5.8_linuxx64_server_dec.tar.gz

$ ls
server_dec  v11.5.8_linuxx64_server_dec.tar.gz

移至提取的目录并执行db2prereqcheck命令这将检查安装DB2的先决条件要求

$ cd server_dec

$ ls
db2  db2_deinstall  db2_install  db2checkCOL.tar.gz  db2checkCOL_readme.txt  db2ckupgrade  db2ls  db2prereqcheck  db2setup  installFixPack

$ sudo ./db2prereqcheck

For more information see the DB2 installation log at
"/tmp/db2_install.log.5295".

$ cat /tmp/db2_install.log.5295
Post-installation instructions
-------------------------------

Required steps:
Set up a DB2 instance to work with DB2.

Optional steps:
Notification SMTP server has not been specified. Notifications cannot be sent to contacts in your contact list until this is specified. For more information see the DB2 administration documentation.

To validate your installation files, instance, and database functionality, run the Validation Tool, /opt/ibm/db2/V11.5/bin/db2val. For more information, see "db2val" in the DB2 Information Center.

让我们通过执行db2val命令来验证我们的安装并验证日志文件我们可以看到一切都还好

$ sudo /opt/ibm/db2/V11.5/bin/db2val
DBI1379I  The db2val command is running. This can take several minutes.

DBI1335I  Installation file validation for the DB2 copy installed at
      /opt/ibm/db2/V11.5 was successful.

DBI1343I  The db2val command completed successfully. For details, see
      the log file /tmp/db2val-230430_051357.log.

DBI1343I  The db2val command completed successfully. For details, see
      the log file /tmp/db2val-230430_051357.log.

后安装

为DB2创建所需的组

$ sudo groupadd -g 998 db2iadm1

$ sudo groupadd -g 997 db2fsdm1

$ sudo groupadd -g 996 dasadm1

为DB2创建所需的用户

$ sudo useradd -u 1004 -g db2iadm1 -m -d /home/db2inst1 db2inst1

$ sudo useradd -u 1003 -g db2fsdm1 -m -d /home/db2fenc1 db2fenc1

$ sudo useradd -u 1002 -g dasadm1 -m -d /home/dasusr1 dasusr1

为用户设置密码

$ sudo passwd db2inst1
New password:
Retype new password:
passwd: password updated successfully

$ sudo passwd db2fenc1
New password:
Retype new password:
passwd: password updated successfully

$ sudo passwd dasusr1
New password:
Retype new password:
passwd: password updated successfully

使用db2icrt命令为DB2创建一个实例，并验证日志文件以获取有关连接到数据库的信息

$ sudo /opt/ibm/db2/V11.5/instance/db2icrt -a server -u db2fenc1 db2inst1
DBI1446I  The db2icrt command is running.


DB2 installation is being initialized.

$ cat /tmp/db2icrt.log.85927

Required steps:
You can connect to the DB2 instance "db2inst1" using the port number "25000". Record it for future reference.

让我们使用以下命令启动数据库实例

$ sudo su - db2inst1

$ db2ls

You can issue database manager commands and SQL statements from the command
prompt. For example:
    db2 => connect to sample
    db2 => bind sample.bnd

For general help, type: ?.
For command help, type: ? command, where command can be
the first few keywords of a database manager command. For example:
 ? CATALOG DATABASE for help on the CATALOG DATABASE command
 ? CATALOG          for help on all of the CATALOG commands.

To exit db2 interactive mode, type QUIT at the command prompt. Outside
interactive mode, all commands must be prefixed with 'db2'.
To list the current command option settings, type LIST COMMAND OPTIONS.
