Shell scripts for daily use

1, shell implementation without password login

host=$1<<ssh-copy-ID"Password: "  "123456\r"expect eofeof

2. A node-categorized shell script

network="eth0"host1=`uname-N ' base=`uname-n|Cut-C1-3' Id1=`uname-n|Cut-C4-6`if((Ten# $id 12==1)); Then((Id2=Ten# $id 1+1))Else((Id2=Ten# $id 1-1))fiif((Ten# $id 1 <9||Ten# $id 1 = =Ten)); ThenHost2=${base}xx${id2}elif((Ten# $id 1 < About||Ten# $id 1 = = -)); ThenHost2=${base}0${id2}ElseHost2=${base}${id2}fi

3, Yum Source configuration method, yum source target file is/etc/yum.repos.d/yum.repo

4, tiotest Test disk array Performance script (nohup background execution)

5. Simple script to test the performance of the disk array using Tiotest

#cd/mnt/1; Nohup tiotest-f20000-B1048576-T8>/tmp/d1. 'hostname'. Out2>&1&#cd/mnt/2; Nohup tiotest-f20000-B1048576-T8>/tmp/d2. 'hostname'. Out2>&1&#cd/mnt/3; Nohup tiotest-f20000-B1048576-T8>/tmp/d3. 'hostname'. Out2>&1&CD/mnt/4; Nohup tiotest-f20000-B1048576-T8>>/tmp/d4. 'hostname'. Out2>&1&CD/mnt/5; Nohup tiotest-f20000-B1048576-T8>>/tmp/d5. 'hostname'. Out2>&1&CD/mnt/6; Nohup tiotest-f20000-B1048576-T8>>/tmp/d6. 'hostname'. Out2>&1&~

6. Use of redirection symbols

1> refers to the standard information output path
2> refers to the error message output path
2>&1 Specify the standard information output path as the error message output path (that is, all output together)

7. Add Environment variables

#!/bin/SHExport Sw_cluster_path=/usr/sw-Cluster export Mpi_root= $SW _cluster_path/MPI2 Export Slurm_root= $SW _cluster_path/slurm-14.11.3Source $SW _cluster_path/intel/composer_xe_2013_sp1.3.174/bin/compilervars.SHIntel64 source $SW _cluster_path/intel/composer_xe_2013_sp1.4.211//bin/compilervars.sh Intel64Export 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. Simple script using Tiotest

Base= 'hostname|Cut-C5-6' (IDX=Ten# $base *3-3))   if[x$1= x]; Then        Echo "too few argument"Exit1   fi   mkdir-P result/$1   CP/tmp/*. Out result/$1/   for ((i= $idx;i< $idx +3;i++));d o rm-fr ost$i; done   for ((i= $idx;i< $idx +3;i++);d o        mkdir ost$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 &  &nb sp;     CD.    done 9, simple test script using tiotest       base= ' hostname|cut-c 5-6 '       ((idx=10# $base *3-3)    true   do   for ((i= $idx;i< $idx +3;i++));d o rm-fr ost$i; done   for ((i= $idx;i< $idx +3;i++);d o        mkdir ost$i        LFS setstripe-i $i-C 1 ost$i    & nbsp;   CD ost$i        nohup tiotest-b 1048576-f 20000-t 8-k1-k2-k3 &G T /tmp/ost$i.out 2>&1 &        done         Sleep 600        CD.    done   Done

10. Mount NFS Network File system

    mkdir /usr/sw-cluster-Mount -T NFS  nfs_nas:/vol/vol_nas001/sw-cluster/usr/sw- mkdir /usr/sw-mpp-Mount -T NFS Nfs_nas:/vol/vol_nas001/sw-mpp-app/usr/sw-mpp

11, a sort of small instructions
