ubuntu安装AMH

挂载数据盘

查看数据盘
```
fdisk -l 
```

可以看到类似输出

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000af383
Device Boot      Start         End      Blocks   Id System
/dev/sda1   *           1        1244     9992398+ 83 Linux
Disk /dev/sdb: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

这里可以看到/dev/xvdb 就是新添加的硬盘，需要给新的硬盘分区。在终端输入：

fdisk /dev/xvdb

之后键入：m，可以看到帮助信息，
键入：n，添加新分区
键入：p，选择添加主分区
键入：l，选择主分区编号为1，这样创建后的主分区为xvdb1
之后，fdisk会让你选择该分区的开始值和结束值，直接回车
最后键入：w，保存所有并退出，完成新硬盘的分区。

2 . 格式化磁盘

mkfs -t ext3 /dev/xvdb1

用ext3格式对/dev/xvdb1 进行格式化

3 . 挂载该分区到 /home

echo '/dev/xvdb1  /home ext3    defaults    0  0' >> /etc/fstab

cat /etc/fstab

命令查看结果

4 . 挂载新分区

mount -a

然后用

df -h

命令查看，出现以下信息就说明挂载成功，可以开始使用新的分区了。

附加步骤（可选）更新ubuntu源，换成国内的源

编辑以下文件，替换里面的内容为阿里云服务器或其它国内服务器的内容之一

/etc/apt/sources.list

然后

apt-get update

安装AMH

参见官网说明

wget http://amh.sh/file/AMH/4.2/amh.sh && chmod 775 amh.sh && ./amh.sh 2>&1 | tee amh.log

将数据库目录连接到数据盘（重要）

操作前，把PHP、MySQL、Nginx都停止了

amh nginx stop
amh php stop
amh mysql stop

建立数据库文件目录链接

cd /home
mkdir mysqldata
cd /usr/local/mysql  #进入数据库文件的上层目录
mv data /home/mysqldata           #把data文件夹转移到/mnt目录
ln -s  /home/mysqldata/data

完成后重新启动面板

/etc/init.d/amh-start
