自动分区、格式化、挂载脚本
功能：自动检测是否有尚未分区的数据盘，格式化新的数据盘并自动挂载
解决了什么问题：一键式检测是否有尚未分区的数据盘，并能对其格式化和自动挂载，省去了复杂的命令和步骤
执行方法：以root身份执行命令
| 1 2 3 | wget http: //mirrors .linuxeye.com /scripts/auto_fdisk .sh chmod +x auto_fdisk.sh . /auto_fdisk .sh |
结果：出现如下即自动分区、格式化、挂载成功：
脚本内容如下：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 | #!/bin/bash # author: yeho <lj2007331 at gmail.com> # blog: https://blog.linuxeye.com # # notes: oneinstack for centos/radhat 5+ debian 6+ and ubuntu 12+ # # project home page: # http://oneinstack.com # https://github.com/lj2007331/oneinstack export path= /usr/local/sbin : /usr/local/bin : /sbin : /bin : /usr/sbin : /usr/bin clear printf " ####################################################################### # oneinstack for centos/radhat 5+ debian 6+ and ubuntu 12+ # # auto fdisk # # for more information please visit http://oneinstack.com # ####################################################################### " echo = echo for cmd in echo /bin/echo ; do $cmd > /dev/null 2>&1 || continue if ! $cmd -e "" | grep -qe '^-e' ; then echo =$cmd break fi done csi=$($ echo -e "\033[" ) cend= "${csi}0m" cdgreen= "${csi}32m" cred= "${csi}1;31m" cgreen= "${csi}1;32m" cyellow= "${csi}1;33m" cblue= "${csi}1;34m" cmagenta= "${csi}1;35m" ccyan= "${csi}1;36m" csuccess= "$cdgreen" cfailure= "$cred" cquestion= "$cmagenta" cwarning= "$cyellow" cmsg= "$ccyan" # check if user is root [ $( id -u) != "0" ] && { echo "${cfailure}error: you must be root to run this script${cend}" ; exit 1; } mount_dir= /data fstab_file= /etc/fstab count=0 tmp1= /tmp/ .tmp1 tmp2= /tmp/ .tmp2 > $tmp1 > $tmp2 # check lock file, one time only let the script run one time lockfile= /tmp/ .$( basename $0) if [ -f "$lockfile" ]; then echo echo "${cwarning}the script is already exist, please next time to run this script${cend}" echo exit else echo echo "${cmsg}step 1.no lock file, begin to create lock file and continue${cend}" echo touch $lockfile fi # check disk partition check_disk() { > $lockfile for i in ` fdisk -l | grep "disk" | grep "/dev" | awk '{print $2}' | awk -f: '{print $1}' | grep "vd" ` do device_count=$( fdisk -l $i | grep "$i" | awk '{print $2}' | awk -f: '{print $1}' | wc -l) new_mount=$( df -h) if [ $device_count -lt 2 ]; then if [ -n "$(echo $new_mount | grep -w " $i ")" -o "$(grep -v '^#' $fstab_file | grep -v ^$ | awk '{print $1,$2,$3}' | grep -w " $i " | awk '{print $2}')" == '/' -o "$(grep -v '^#' $fstab_file | grep -v ^$ | awk '{print $1,$2,$3}' | grep -w " $i " | awk '{print $3}')" == 'swap' ]; then echo "${cwarning}the $i disk is mounted${cend}" else echo $i >> $lockfile echo "you have a free disk, now will fdisk it and mount it" fi fi done disk_list=$( cat $lockfile) if [ "x$disk_list" == "x" ]; then echo echo "${cwarning}no free disk need to be fdisk. exit script${cend}" echo rm -rf $lockfile exit 0 else echo "${cmsg}this system have free disk :${cend}" for i in ` echo $disk_list` do echo "$i" count=$((count+1)) done [ $count -gt 1 ] && { echo "${cwarning}this system has at least two free disk, you must manually mount it${cend}" ; exit 0; } fi } # check os check_os() { os_release=$( grep "aliyun linux release" /etc/issue 2> /dev/null ) os_release_2=$( grep "aliyun linux release" /etc/aliyun-release 2> /dev/null ) if [ "$os_release" ] && [ "$os_release_2" ]; then if echo "$os_release" | grep "release 5" > /dev/null 2>&1; then os_release=aliyun5 modify_env fi fi } # install ext4 modify_env() { modprobe ext4 yum -y install e4fsprogs } # fdisk ,formating and create the file system fdisk_fun() { fdisk -s 56 $1 << eof n p 1 wq eof sleep 5 mkfs.ext4 ${1}1 } # make directory make_dir() { echo "${cmsg}step 4.begin to make directory${cend}" [ -d "$mount_dir" ] && mv ${mount_dir}{,_bk} mkdir -p $mount_dir echo "$mount_dir" >> $tmp1 } # config /etc/fstab and mount device main() { for i in ` echo $disk_list` do echo echo "${cmsg}step 3.begin to fdisk free disk${cend}" [ -n "`df -h | grep ${i}1`" ] && { echo "${cfailure}the ${i}1 already mount${cend}" ; echo ; exit 0; } fdisk_fun $i > /dev/null 2>&1 echo echo "${i}1" >> $tmp2 done make_dir > $lockfile paste $tmp2 $tmp1 > $lockfile echo echo "${cmsg}step 5.begin to write configuration to /etc/fstab and mount device${cend}" while read a b do [ -z "`grep ^${a} $fstab_file`" -a -z "`grep ${b} $fstab_file`" ] && echo "${a} $b ext4 defaults 0 0" >> $fstab_file done < $lockfile mount -a echo } # start script echo "${cmsg}step 2.begin to check free disk${cend}" #service mysqld stop #mv /data /root check_os check_disk main df -h #mv /root/data/* /data #service mysqld start rm -rf $lockfile $tmp1 $tmp2 |
