db2 9.7 for linux 5.4安装详细步骤 1、解压缩安装包 #gunzip v9.7_linuxia32_server.tar.gz #tar -xvf v9.7_linuxia32_server.tar 2、进入解压后的文件目录，执行安装：（我们选择手动安装） 注意：DB2_install为手动安装 db2_setup为图形安装 www.2cto.com #./Db2_install-------no-----aese 3、创建DB2运行所需的组和用户： #groupadd -g 901 db2grp #groupadd -g 902 db2fgrp #groupadd -g 903 db2agrp #useradd -g db2grp -u 801 -d /home/db2inst1-m -s /bin/bash db2inst1 --管理当前实例 #useradd -g db2fgrp -u 802 -d /home/db2fenc-m -s /bin/bash db2fenc #useradd -g db2agrp -u 803 -d /home/db2das-m -s /bin/bash db2das --管理所有实例 4、设置密码： passwd db2inst1 passwd db2fenc passwd db2das 5、创建实例 #cd /opt/ibm/db2/V9.7/instance #./dascrt -u db2das #./db2icrt -u db2inst1 db2inst1 注意：DBI1922N The host name is not valid.报无法解析错误，在/etc/hosts文件中添加解析参数即可 www.2cto.com 注释： 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db2das。 db2icrt：创建的是实例，其名字一般和管理用户名一样，这里均为db2inst1。 6、启动DB2 # su - db2das $ db2admin start ----启动DB2管理服务器 SQL4409W The DB2 Administration Server is already active. $su - db2inst1 $ db2start ----启动数据库实例 05/07/2012 01:30:04 0 0 SQL1063N DB2START processing was successful. SQL1063N DB2START processing was successful. 7、检查DB2是否起来，状态如下： [db2inst1@jetsen ~]$ ps -ef|grep db2 db2das 10828 1 0 01:23 ? 00:00:00 /home/db2das/das/adm/db2dasrrm root 11345 1 0 01:23 ? 00:00:00 /opt/ibm/db2/V9.7/bin/db2fmcd db2das 11354 1 0 01:23 ? 00:00:00/opt/ibm/db2/V9.7/das/bin/db2fmd -i db2das -m/opt/ibm/db2/V9.7/das/lib/libdb2dasgcf.so.1 root 17267 2768 0 01:29 pts/1 00:00:00 su - db2das db2das 17268 17267 0 01:29 pts/1 00:00:00 -bash root 17329 17268 0 01:29 pts/1 00:00:00 su - db2inst1 db2inst1 17332 17329 0 01:29 pts/1 00:00:00 -bash root 17446 1 1 01:29 pts/1 00:00:01 db2wdog 0 db2inst1 17448 17446 1 01:29 pts/1 00:00:01 db2sysc 0 root 17449 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0 root 17450 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0 www.2cto.com root 17451 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0 db2inst1 17455 17448 1 01:30 pts/1 00:00:01 db2vend (PD Vendor Process -1) db2inst1 17462 17446 0 01:30 pts/1 00:00:01 db2acd 0,0,0,0,1,0,0,0000,1,0,8a67a4,14,1e014,2,0,1,11fd0,0x125f0000,0x125f0000,1600000,588003,2,b5800b db2inst1 17494 17332 0 01:32 pts/1 00:00:00 ps -ef db2inst1 17495 17332 0 01:32 pts/1 00:00:00 grep db2 [db2inst1@jetsen ~]$ 8、配置DB2自动启动，用root用户登录 #cd /opt/ibm/db2/V9.7/instance/ # ./db2iauto -on db2inst1 9、配置网络 #su - db2inst1 $db2 update dbm cfg using SVCENAME50000 ----改变DB2的远程访问端口，默认是5000 $db2set DB2COMM=TCPIP ----修改DB2的连接方式为TCPIP， 注意：也可以通过JDBC,ODBC等方式来访问DB2数据库 10、实例的启动和关闭 #su - db2inst1 $db2 force applications all ----关闭所有和DB2相关的应用程序 $db2stop ----关闭数据库实例 $db2start ----启动数据库实例 11、创建数据库 #su - db2inst1 $db2 create database test ----创建数据库实例 DB20000I The CREATE DATABASE command completed successfully. 12、连接到我们刚才创建的数据库 #su - db2inst1 $db2 www.2cto.com db2 => Connect to test user db2inst1 Enter current password for db2inst1: Database Connection Information Database server = DB2/LINUX 9.7.5 SQLauthorization ID = DB2INST1 Local database alias = TEST db2 => 附录： 1、创建演示数据库 #su - db2inst1 $ $cd /opt/ibm/db2/V9.7/bin $ ./db2sampl Creating database "SAMPLE"...
