solusvm 主控端迁移

难点在于solusvm被控端已经开了小鸡的情况。

备份数据库：

#!/bin/sh

## Vars
CONF=/usr/local/solusvm/includes/solusvm.conf
FILENAME=solusvm_database_dump.gz

## Get the database details
DN=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DU=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DP=`grep -m1 $: ${CONF} | cut -d ':' -f `;

## Do the dump
echo "Dumping database..."
mysqldump --opt -h localhost --user=${DU} --password=${DP} ${DN} > ~/${FILENAME};
echo "Complete."

新主动端恢复数据库：

#!/bin/sh

## Vars
CONF=/usr/local/solusvm/includes/solusvm.conf
FILENAME=solusvm_database_dump.gz

## Get the database details
DN=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DU=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DP=`grep -m1 $: ${CONF} | cut -d ':' -f `;

## Do the dump
echo "Restoring database..."
mysql --user=${DU} --password=${DP} ${DN} < ~/${FILENAME};
echo "Complete."

注意恢复数据库后，重新到界面对node，更新其key password。

顺便改进下，做个快键键登录连接数据库：

!/bin/sh

## Vars
CONF=/usr/local/solusvm/includes/solusvm.conf

## Get the database details
DN=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DU=`grep -m1 $: ${CONF} | cut -d ':' -f `;
DP=`grep -m1 $: ${CONF} | cut -d ':' -f `;

mysql --user=${DU} --password=${DP} ${DN};
