[root@localhost opt]# ls

4.注册license
[root@localhost opt]# cd ibm/db2/V9.7/adm
[root@localhost adm]# pwd
/opt/ibm/db2/V9.7/adm
[root@localhost adm]# ls
cieadmsv cieprcnt db2audit db2chparm db2fmp db2genp db2govlg db2inidb db2path db2rfpen db2set db2stop db2sysc

[root@localhost adm]#
5.创建三个用户组
[root@localhost adm]# groupadd -g 901 db2iadm1
[root@localhost adm]# groupadd -g 902 db2fadm1
[root@localhost adm]# groupadd -g 903 db2dadm1
6.创建三个用户(分别是拥有实例的用户,受防护的用户,DAS用户)且指定对应的用户组
[root@localhost adm]# useradd -g db2iadm1 -u 101 -d /home/db2inst1 -m db2inst1
[root@localhost adm]# useradd -g db2fadm1 -u 102 -d /home/db2fenc1 -m db2fenc1
[root@localhost adm]# useradd -g db2dadm1 -u 103 -d /home/db2dasusr1 -m db2dasusr1
参数说明:
-u uid 使用者的ID值,必须为唯一的ID值,除非用-o选项可以不唯一,数字不可为负值,0~999传统上是保留给系统帐号使用。
-d path 使用者目录
-m 使用者目录如不存在则自动建立
-s shell 使用者登入后使用shell名称作为提示符,如果不写系统会帮你指定预设的登入shell
例子:
[root@localhost ~]# groupadd -g 888 testgroup
[root@localhost ~]# useradd -g testgroup -u 555 -d /home/testuser1 -m testuser1
或[root@localhost ~]# useradd -g testgroup -u 555 -d /home/testuser1 -m -s /bin/sh testuser1
[root@localhost ~]# userdel testuser1
[root@localhost ~]# groupdel testgroup
当加上-s /bin/sh时,在root用户下切换到testuser1时变成sh-3.1$
查看echo $PS1变成了\s-\v\$
所以想更改成以前的那种登陆提示符,修改PS1环境变量的值
sh-3.1$ export PS1="[\u@\h \W]\$ "
\h 显示主机名
\u 显示当前用户的用户名
\W 显示当前工作目录的名字
\w 显示当前工作目录的路径
\s 显示当前运行的shell的名字
\v 显示shell的版本
\t 显示当前时间
\d 显示当前日期
\\ 显示反斜杠
\$ 显示$符作为提示符,如果用户是root的话,则显示#号
\# 显示当前命令的命令编号
\! 显示该命令的历史记录编号
\n 打印新行
\nnn 显示nnn的八进制值
7.添加三个用户的密码
添加实例的用户密码
[root@localhost adm]# passwd db2inst1
Changing password for user db2inst1.
New UNIX password: 输入新密码(如Sunrier)
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password: 再输入新密码(如Sunrier,跟第一次输入相同)
passwd: all authentication tokens updated successfully.
[root@localhost adm]#
添加受防护的用户密码
[root@localhost adm]# passwd db2fenc1
Changing password for user db2fenc1.
New UNIX password: 输入新密码
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password: 再输入新密码(两次需相同,否则需要重新输入)
passwd: all authentication tokens updated successfully.
[root@localhost adm]#
添加DAS用户密码
[root@localhost adm]# passwd db2dasusr1
Changing password for user db2dasusr1.
New UNIX password: 输入新密码
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password: 再输入新密码(两次需相同,否则需要重新输入)
passwd: all authentication tokens updated successfully.
[root@localhost adm]#
8.检查用户组和用户是否创建成功
用户组: more /etc/group | grep db2
用户: more /etc/passwd | grep db2
[root@localhost adm]# more /etc/group | grep db2
db2iadm1:x:901:
db2fadm1:x:902:
db2dadm1:x:903:
[root@localhost adm]# more /etc/passwd | grep db2
db2inst1:x:101:901::/home/db2inst1:/bin/sh
db2fenc1:x:102:902::/home/db2fenc1:/bin/sh
db2dasusr1:x:103:903::/home/db2dasusr1:/bin/sh
[root@localhost adm]#
9.创建实例
进入/opt/ibm/db2/V9.7/instance目录
[root@localhost adm]# cd /opt/ibm/db2/V9.7/instance
[root@localhost instance]# pwd
/opt/ibm/db2/V9.7/instance
[root@localhost instance]# ./dascrt -u db2dasusr1 (注:创建DB2管理服务器)
[root@localhost instance]# ./db2icrt -u db2fenc1 db2inst1 (注:创建DB2实例)
或者[root@localhost instance]# ./db2icrt -a server -u db2fenc1 db2inst1 (注:创建DB2实例)
这里dascrt创建的是DB2 adminstration server,每台服务器只有一个这种server,为进行DB2管理(比如运行控制中心)所必须,同时指定其管理用户是db2dasusr1 ,db2icrt创建的是实例,其名字一般和管理用户名一样,这里db2fenc1指定db2inst1为它的防护用户,而db2inst1为一实例用户
10.配置DB2
1)设置DB2自启动(注:依然在root用户下)
[root@localhost instance]# pwd
/opt/ibm/db2/V9.7/instance
[root@localhost instance]# ./db2iauto -on db2inst1
db2set MsgRC=1306, P1=\'\', P2=\'\'
[root@localhost instance]#
设置对db2inst1在Linux启动时自动启动。
2)修改网络服务端口(注:在db2inst1用户下)
修改DB2的服务端口为50658,默认情况下端口是50000
[root@localhost instance]# su - db2inst1
[db2inst1@localhost ~]$ db2 update dbm cfg using SVCENAME 50658
DB20000I The UPDATE DATABASE MANAGER CONFIGURATION command completed
successfully.
[db2inst1@localhost ~]$
3)修改DB2连接方式为TCP/IP
[db2inst1@localhost ~]$ db2set DB2COMM=TCPIP
[db2inst1@localhost ~]$
修改DB2连接方式为TCPIP,然后可通过JDBC、ODBC等访问本DB2服务器上的数据库,安装了DB2客户端的其它机器也可访问数据库。
11.查看DB2许可证情况
[root@localhost ~]$ su - db2inst1
[db2inst1@localhost ~]$ db2licm -l
