1、IP规划
vi /etc/hosts
#rac1
192.168.75.11 rac1
192.168.72.13 rac1-vip
10.0.2.11 rac1-priv
#rac2
192.168.75.12 rac2
192.168.75.14 rac2-vip
10.0.10.12 rac2-priv
#Scan IP
192.168.75.24 rac-scan
2、挂载
mount /dev/cdrom /mnt
cd /etc/yum.repos.d
mkdir bk
mv *.repo bk/
echo "[AppStream]" >> /etc/yum.repos.d/rhel.repo
echo "name =AppStream" >> /etc/yum.repos.d/rhel.repo
echo "baseurl=file:///mnt/AppStream" >> /etc/yum.repos.d/rhel.repo
echo "gpgcheck=0" >> /etc/yum.repos.d/rhel.repo
echo "enabled=1" >> /etc/yum.repos.d/rhel.repo
echo "[BaseOS]" >> /etc/yum.repos.d/rhel.repo
echo "name =BaseOS" >> /etc/yum.repos.d/rhel.repo
echo "baseurl=file:///mnt/BaseOS " >> /etc/yum.repos.d/rhel.repo
echo "gpgcheck=0" >> /etc/yum.repos.d/rhel.repo
echo "enabled=1" >> /etc/yum.repos.d/rhel.repo
cat /etc/yum.repos.d/rhel.repo
3、iscsi
yum install iscsi-initiator-utils -y
rpm -ivh /mnt/Packages/iscsi-initiator-utils-6.2.0.874-10.el7.x86_64.rpm
cat /etc/iscsi/initiatorname.iscsi
echo "options=--whitelisted --replace-whitespace" > /etc/scsi_id.config
systemctl enable iscsi
systemctl start iscsi
iscsiadm -m discovery -t st -p 192.168.75.100:3260
iscsiadm -m discovery -t st -p 10.0.10.100:3260
iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.a631d70891ee -p 192.168.75.100:3260 -l
iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.a631d70891ee -p 10.0.10.100:3260 -l
4、multipath
rpm -qa|grep multipath
modprobe dm-multipath
modprobe dm-round-robin
lsmod |grep dm_multipath
systemctl enable multipathd
systemctl start multipathd
multipath -v2
cp /usr/share/doc/device-mapper-multipath/multipath.conf /etc/multipath.conf
for i in `cat /proc/partitions | awk '{print$4}' |grep sd | grep [a-z]$`; do
echo "### $i: `/lib/udev/scsi_id --whitelisted --device=/dev/$i`"; done
iscsiadm -m session -P 3 |grep "Attached"
fdisk -l|grep "/dev/sd"
ls -l /dev/disk/by-id
multipath -ll|grep mpath
for i in a b;
do
echo "sd$i" "`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i` ";
done
