【操作步骤】

1.安装

解压： db2_v101_linuxia32_expc.tar.gz
cd expc/
./db2_intall

2配置

2.1添加组和用户

[root@localhost expc]# groupadd -g 2000 db2iadm1
[root@localhost expc]# groupadd -g 2001 db2fadm1
[root@localhost expc]# useradd -m -g db2iadm1 -d /home/db2inst1 db2inst1
[root@localhost expc]# useradd -m -g db2fadm1 -d /home/db2fenc1 db2fenc1
[root@localhost expc]# passwd db2inst1
[root@localhost expc]# passwd db2fenc1

2.2创建实例样本

[root@localhost instance]# pwd
/opt/ibm/db2/V10.1/instance
[root@localhost instance]# chmod -R 775 *
[root@localhost instance]# ./db2icrt -p 50000 -u db2fenc1 db2inst1
[root@localhost instance]# su - db2inst1
[db2inst1@localhost ~]$ db2sampl

[db2inst1@localhost ~]$ db2start
SQL1026N The database manager is already active.
[db2inst1@localhost ~]$ db2 connect to sample
Database Connection Information
Database server = DB2/LINUX 10.1.2
SQL authorization ID = DB2INST1
Local database alias = SAMPLE

2.3 创建das管理

为了远程客户端能够用控制中心来控制数据库服务器，需要在数据库服务器上安装 das,当然，如果只是远程连接而不是远程管理，可以不用装，这里我安装了一下。

[root@localhost expc]# groupadd -g 2002 db2asgrp
[root@localhost expc]# useradd -m -g db2asgrp -d /home/db2as db2as
[root@localhost expc]# passwd db2as
[db2as@localhost ~]$ su - db2as # 这里测试新建用户
[db2as@localhost ~]$ su # 这里进入root权限
[root@localhost ~]# cd /opt/ibm/db2/V10.1/instance/
[root@localhost instance]# ./dascrt -u db2as
DBI1070I Program dascrt completed successfully.
[root@localhost instance]# su - db2as
[db2as@localhost ~]$ db2admin start
SQL4409W The DB2 Administration Server is already active.

3设置端口号

vim /etc/services
su - db2inst1
db2set DB2_EXTENDED_OPTIMIZATION=ON
db2set DB2_DISABLE_FLUSH_LOG=ON
db2set AUTOSTART=YES
db2set DB2_STRIPED_CONTAINERS=ON
db2set DB2_HASH_JOIN=Y
db2set DB2COMM=tcpip
db2set DB2_PARALLEL_IO=*
db2set DB2CODEPAGE=819 # PS:这个地方比较重要
# db2 update database manager configuration using svcename db2inst1
