VmVare的centos虚拟主机琐碎

安利一篇我翻译的国外大牛的神经网络入门文章

克隆虚拟主机时候需要重新生成网卡的mac地址

启动完成需要修改/etc/udev/rule.d/70-presistent-net.rules将老的网卡(即被克隆之前的网卡)删除，并且需要将新的网卡名称改成老的网卡名称(看一下就知道了)

修改主机名称

修改文件/etc/sysconfig/network

修改虚拟机网络连接中的物理地址

新增硬盘后如何初始化并挂载

假设新增的硬盘为/dev/sdb
则开机后root执行下面的命令

[root@centos66-2 liujinliu]# fdisk /dev/sdb

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

Command (m for help): n  ----选择新建分区
Command action
   e   extended
   p   primary partition (1-4)
p ---选择新建主分区

分区建好后需要格式化并挂载

mkfs.ext4 /dev/sdb1
mkdir /srv/docker_reg_disk
mount /dev/sdb1 /srv/docker_reg_disk

为了让开机时自动挂载需要修改文件/etc/fstab，增加如下内容:
