注意：本文中的磁盘/dev/xvdb 为作者测试服务器上的命名，在您的服务器中可能是 /dev/sdb /dev/vdb 等等，请按您的磁盘名称修改</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
0、创建挂载目录</p><pre class="brush:bash;toolbar:false">mkdir -p /www</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">1、确认是否有没有分区的磁盘,如下图，没有分区的磁盘是 /dev/xvdb ,在您的服务器中可能是 /dev/vdb 请注意按实际名称修改<br/></p><pre class="brush:bash;toolbar:false">fdisk -l</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764678622386.png" src="/uploads/allimg/180307/144S21W4-0.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
2、为磁盘分区，若已分区的，请跳过！</p><pre class="brush:bash;toolbar:false">fdisk /dev/xvdb</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764678825970.png" src="/uploads/allimg/180307/144S2B59-1.png" style="margin: 0px; padding: 0px; border: 0px none; box-sizing: inherit !important;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
3、输入n开始创建分区</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="1476467888753.png" src="/uploads/allimg/180307/144S2J61-2.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
4、输入p创建主分区</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764678911902.png" src="/uploads/allimg/180307/144S2N29-3.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
5、选择分区号，这里输入1</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764678974383.png" src="/uploads/allimg/180307/144S2M51-4.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
6、输入分区开始位置，直接回车</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679066906.png" src="/uploads/allimg/180307/144S23Z3-5.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
7、输入分区结束位置，直接回车</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679101188.png" src="/uploads/allimg/180307/144S22D5-6.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
8、输入wq 保存退出</p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679123835.png" src="/uploads/allimg/180307/144S221W-7.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
9、检查是否分区成功</p><pre class="brush:bash;toolbar:false">fdisk -l</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679159426.png" src="/uploads/allimg/180307/144S2I23-8.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
10、格式化分区，这里请输入你看到的磁盘加分区号，如下图，已格式化过的，请跳过</p><pre class="brush:bash;toolbar:false">mkfs.ext4 /dev/xvdb1</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679185233.png" src="/uploads/allimg/180307/144S24E9-9.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679237879.png" src="/uploads/allimg/180307/144S22R6-10.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
11、将分区挂载信息添加到开启动挂载</p><pre class="brush:bash;toolbar:false">echo "/dev/xvdb1 /www ext4 defaults 0 0" >> /etc/fstab</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679262526.png" src="/uploads/allimg/180307/144S250W-11.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
12、重新挂载所有分区</p><pre class="brush:bash;toolbar:false">mount -a</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679301321.png" src="/uploads/allimg/180307/144S25629-12.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;">
13、检查是否挂载成功</p><pre class="brush:bash;toolbar:false">df</pre><p style="margin: 0px 0px 6px; padding: 0px; box-sizing: inherit !important;"><img alt="14764679337124.png" src="/uploads/allimg/180307/144S23P0-13.png" style="margin: 0px; padding: 0px; box-sizing: inherit !important; border: 0px none; max-width: 100%;"/></p><ul class="clearfix list-unstyled list-paddingleft-2" style="list-style-type: none;"><li><p>
</p></li></ul><p><br/></p>
