linux命令进入db2 linux命令进入桌面( 三 )

IT技术执行


5、ISCSI 共享存储配置
Iscsi server端配置(node01上执行):
修改/etc/ietd.conf,添加如下内容：
Target iqn.2014-03.node01.site:scsidisk01
Lun 0 Path=/dev/sda4,Type=fileio
注意：我的未分区硬盘为/dev/sda4,你的可能不一样的@_@~~~~
添加自启动
#chkconfig -a iscsitarget
检查是否成功
#chkconfig -l iscsitarget
结果：iscsitarget 0:off 1:off 2:off 3:on 4:off 5:on 6:off
重启iscsitarget服务
# /etc/init.d/iscsitarget restart
iscsi client端配置(node01、node02、node03执行,):
iscsitarget文件内容如下:
#! /bin/sh
### BEGIN INIT INFO
# Provides: iscsiclsetup
#node02与node03上如果未装iscsitarget需将下下行的$iscsitarget
# Required-Start: $network $syslog $iscsitarget $remote_fs smartd
# Required-Stop:
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Description: ISCSI client setup
### END INIT INFO
case "$1" in start)
iscsiadm --mode discoverydb --type sendtargets --portal 192.168.18.201 --discover
iscsiadm --m node --targetname iqn.2014-03.node01.site:scsidisk01 --portal 192.168.18.201:3260 --login
;;
stop)
iscsiadm -m node -T iqn.2014-03.node01.site:scsidisk01 -p 192.168.18.201 --logout
;;
restart) ## Stop the service and regardless of whether it was ## running or not, start it again.
$0 stop
$0 start
;;
*)
Esac
保存后执行:#/etc/init.d/iscsiclient restart
验证iscsiclient是否启动成功:
#fdisk -l
检查有无/dev/sdb出现
6、配置Linux环境变量
/etc/profie.local添加内容
alias sl='tail -f /var/log/messages'
alias fc='fcslogrpt /var/log/messages'
export PATH=/root/bin:/usr/sbin/rsct/bin:/opt/ibm/db2/v10.5/bin:$PATH
export PATH=/usr/lpp/mmfs/bin:$PATH
export DB2USENONIB=TRUE
export DB2_CFS_GPFS_NO_REFRESH_DATA=https://www.04ip.com/post/true
然后执行# . /etc/profile.local ， 完成后你就可以安装purescale了，我猜测应该是设置了变量DB2USENONIB ， 使purescale不再要求你强制InfiniBand或万兆网卡，使我等穷人可以有机会玩这种高档、洋气、上档次的数据库 。。。
7、DB2 V10.5 的安装:
node01:~/server_t # ./db2_install
DBI1324W Support of the db2_install command is deprecated. For
more information, see the DB2 Information Center.
