1、shell实现无密码登陆
host=$1 expect << EOF spawn ssh-copy-id $host expect "password:" send "123456\r" expect eof EOF
2、一个节点分类的shell脚本
network="eth0" host1=`uname -n` base=`uname -n|cut -c 1-3` id1=`uname -n|cut -c 4-6` if ((10#$id1 %2 == 1));then ((id2=10#$id1+1)) else ((id2=10#$id1-1)) fi if ((10#$id1 < 9 || 10#$id1 == 10));then host2=${base}00${id2} elif ((10#$id1 < 99 || 10#$id1 == 100));then host2=${base}0${id2} else host2=${base}${id2} fi
rm -fr /tmp/targets mkdir -p /tmp/targets
#ha.cf
cp templates/ha.cf /tmp/targets/ha.cf echo "ucast $network $host2" >> /tmp/targets/ha.cf echo "ping 20.0.255.254" >> /tmp/targets/ha.cf echo "auto_failback on" >> /tmp/targets/ha.cf echo "node $host1" >> /tmp/targets/ha.cf echo "node $host2" >> /tmp/targets/ha.cf
#haresources
cp templates/haresources /tmp/targets/haresources echo "$host1 Lustre::$host1-targets" >> /tmp/targets/haresources echo "$host2 Lustre::$host2-targets" >> /tmp/targets/haresources #authkeys cp templates/authkeys /tmp/targets/authkeys cp -fr /tmp/targets/ha.cf /etc/ha.d/ cp -fr /tmp/targets/haresources /etc/ha.d/haresources cp -fr /tmp/targets/authkeys /etc/ha.d/authkeys
3、yum源的配置方法,yum源的目标文件为/etc/yum.repos.d/yum.repo
[Server] name=RHEL 6.6 baseurl=ftp://10.0.0.2/mnt/rhel6.6/Server enable=1 gpgcheck=0 gpgkey=ftp://10.0.0.2/mnt/rhel6.6/RPM-GPG-KEY-redhat-release [HA] name=RHEL 6.6 HA baseurl=ftp://10.0.0.2/mnt/rhel6.6/HighAvailability enable=1 gpgcheck=0 gpgkey=ftp://10.0.0.2/mnt/rhel6.6/RPM-GPG-KEY-redhat-release
4、tiotest测试盘阵性能的脚本(nohup 后台执行)
5、使用tiotest测试盘阵性能的简单脚本
#cd /mnt/1;nohup tiotest -f 20000 -b 1048576 -t 8 >/tmp/d1.`hostname`.out 2>&1 & #cd /mnt/2;nohup tiotest -f 20000 -b 1048576 -t 8 >/tmp/d2.`hostname`.out 2>&1 & #cd /mnt/3;nohup tiotest -f 20000 -b 1048576 -t 8 >/tmp/d3.`hostname`.out 2>&1 & cd /mnt/4;nohup tiotest -f 20000 -b 1048576 -t 8 >>/tmp/d4.`hostname`.out 2>&1 & cd /mnt/5;nohup tiotest -f 20000 -b 1048576 -t 8 >>/tmp/d5.`hostname`.out 2>&1 & cd /mnt/6;nohup tiotest -f 20000 -b 1048576 -t 8 >>/tmp/d6.`hostname`.out 2>&1 & ~
6、重定向符号的使用
1> 指标准信息输出路径
2> 指错误信息输出路径
2>&1 将标准信息输出路径指定为错误信息输出路径(也就是都输出在一起)
7、添加环境变量
#!/bin/sh export SW_CLUSTER_PATH=/usr/sw-cluster export MPI_ROOT=$SW_CLUSTER_PATH/mpi2 export SLURM_ROOT=$SW_CLUSTER_PATH/slurm-14.11.3 source $SW_CLUSTER_PATH/intel/composer_xe_2013_sp1.3.174/bin/compilervars.sh intel64 source $SW_CLUSTER_PATH/intel/composer_xe_2013_sp1.4.211//bin/compilervars.sh intel64 export PATH=$PATH:$SLURM_ROOT/bin:$MPI_ROOT/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SLURM_ROOT/lib:$MPI_ROOT/lib export PATH=$PATH:/usr/sw-mpp/bin:/usr/sw-cluster/slurm-14.11.3/bin:
8、使用tiotest的简单脚本
base=`hostname|cut -c 5-6` ((idx=10#$base*3-3)) if [ x$1 = x ];then echo "too few argument" exit 1 fi mkdir -p result/$1 cp /tmp/*.out result/$1/ for((i=$idx;i<$idx+3;i++));do rm -fr OST$i; done for((i=$idx;i<$idx+3;i++));do mkdir OST$i lfs setstripe -i $i -c 1 OST$i if [ $? -ne 0 ];then exit 1 fi cd OST$i nohup tiotest -b 1048576 -f 20000 -t 8 > /tmp/OST$i.out 2>&1 & cd .. done 9、使用tiotest的简单测试脚本 base=`hostname|cut -c 5-6` ((idx=10#$base*3-3)) while true do for((i=$idx;i<$idx+3;i++));do rm -fr OST$i; done for((i=$idx;i<$idx+3;i++));do mkdir OST$i lfs setstripe -i $i -c 1 OST$i cd OST$i nohup tiotest -b 1048576 -f 20000 -t 8 -k1 -k2 -k3 > /tmp/OST$i.out 2>&1 & done sleep 600 cd .. done done
10、挂载nfs网络文件系统
mkdir /usr/sw-cluster -p mount -t nfs nfs_nas:/vol/vol_nas001/sw-cluster /usr/sw-cluster mkdir /usr/sw-mpp -p mount -t nfs nfs_nas:/vol/vol_nas001/sw-mpp-app /usr/sw-mpp
11、 一个排序的小指令
du -sh * |sort -nr
显示出所有文件的排序和大小
