1. Copy tar to /opt, use the root account, and install the software package
cd / opt tar - zxvf v9.5fp3b_linuxx64_server.tar.gz （64 cd server ./db2_install
2. Create users and groups
groupadd -g 999 db2iadm1 groupadd -g 998 db2fadm1 groupadd -g 997 dasadm1
useradd -u 1004 -g db2iadm1 -m -d /home/db2inst1 db2inst1 useradd -u 1003 -g db2fadm1 -m -d /home/db2fenc1 db2fenc1 useradd -u 1002 -g dasadm1 -m -d /home/dasusr1 dasusr1
Ø Change the password for each user
passwd db2inst1 (enter password)
passwd db2fenc1 (enter password)
passwd dasusr1 (enter password)
3. Create a DB2 Administration Server (DAS)
/ opt / ibm / db2 / V9. 7 / instance / dascrt -u dasusr1
4. Create an instance using db2icrt
/opt/ibm/db2/V9.7/instance/db2icrt -a server -u db2fenc1db2inst1
5. Configure the communication protocol of the instance
su - db2inst1 db2set DB2_SKIPINSERTED=ON db2set DB2_EVALUNCOMMITTED=ON db2set DB2_SKIPDELETED=ON db2set DB2_HASH_JOIN=YES db2set DB2_RR_TO_RS=YES db2set DB2CODEPAGE=1386 db2set DB2COMM=TCPIP db2set DB2_PARALLEL_IO=* db2 update dbm cfg using svcename 50000
6. Update the license
Ø Crack and copy the db2ese_t.lic file to the DB2 server /opt/ibm/db2/V9.5/adm/db2licm -a filename filename is the path to the copy of db2ese_t.lic Ø Select language #vi / home / db2inst1 / .bash_profile export LANG =en_US -- add this to the last line of this file Ø View the current DB2 license status are db2inst1 d2licm -l
7. Create the sample database SAMPLE
Under db2inst1, directly enter the command db2sampl
8. Start and stop the database
start database db2start
stop database db2stop
9. Other commonly used SQL
#create database $ db2 "CREATE DATABASE DBTEST1 ALIAS DBTEST1 USING CODESET ISO8859-1 TERRITORY US" $ db2 "CREATE DATABASE DBTEST2 ALIAS DBTEST2 USING CODESET UTF-8 TERRITORY CN" The above statement takes a long time to output "DB20000I The CREATE DATABASE command completed successfully." $ db2 connect to DBTEST1 #create table $ db2 "CREATE table mytaba(col1 INTEGER NOT NULL, col2 VARCHAR(40), col3 DECIMAL(9,2))" #Add record $ db2 "INSERT INTO mytaba(col1,col2,col3) VALUES(1,'hello',9.2)" #Inquire $ db2 "SELECT * FROM mytabaFETCH FIRST 10 ROWS ONLY"
Note: Execute the pre-detection script db2prereqcheck to check the system configuration
Install the pam package (if the execution is unsuccessful, manually make a soft link for libpam.so)
Where --nodeps removes dependencies from package installation
Install compat-libstdc++
