db2没有独立的用户管理系统,必须借助OS用户来提供安全认证
建立三个管理的用户组,分别是das管理组,实例组,受防护组
groupadd -g 900 db2agrp
groupadd -g 901 db2igrp
groupadd -g 902 db2fgrp
添加用户
useradd -m -d /home/db2das -g db2agrp -u 803 db2das
useradd -m -d /home/db2inst1 -g db2igrp -u 801 db2inst1
useradd -m -d /home/db2fenc1 -g db2fgrp -u 802 db2fenc1
设置密码
passwd db2inst1
passwd db2fenc1
passwd db2das
查看是否创建成功
cat /etc/passwd | grep db2
cat /etc/group | grep db2
创建实例,需要有一个db2 用户对DB2进行管理
/opt/ibm/db2/V9.7/instance # ./dascrt -u db2das
./db2icrt -a server -u db2inst1 db2inst1
一般实例名字和其管理用户名是一样的
启动db2admin管理器
su - db2das
db2admin start
启动实例
su - db2inst1
db2start
设置对linux上面的数据库自动启动
./db2iauto -on db2inst1
修改db2的服务端口位50001,默认端口是50000
db2 update dbm cfg using SVCENAME 50001
查看实例的配置信息
db2 get dbm cfg
修改数据库的连接方式为TCPIP
db2set DB2COMM=TCPIP
