2021-11-05 Mysql远程同步数据库的脚本（expect）

cat mysql-dump.sh

#!/usr/bin/expect -f
# 变量定义
set HOST "192.168.26.42"
set USERNAME ipms
set PASSWORD ipms
set DB ipms
set DIR "/home/ipms/bs/bin"
set FILE $DB.bak
set DB_USER root
set DB_PASS root

# 传输文件，直到传输完成
spawn mysqldump -u$DB_USER -p$DB_PASS --databases $DB > $DIR/$FILE
spawn scp -P 22 $DIR/$FILE $USERNAME@$HOST:$DIR/$FILE
expect {
    "password" {set timeout -1; send "$PASSWORDn"; exp_continue;}
    "(yes/no)?" {send "yesn";}
}

# SSH登录
spawn ssh $USERNAME@$HOST
expect {
    "password" {send "$PASSWORDn"}
    "(yes/no)?" {send "yesn";}
}

# 恢复数据库
expect "$USERNAME@*"  {send "mysql -u$DB_USER -p$DB_PASS < $DIR/$FILEn"}

# 退出SSH登录
expect "$USERNAME@*"  {send "exitn"}

expect eof

根据实际测试情况

1. 如果远程已有该数据库，则会被覆盖。
2. 如果远程无该数据库，则会被增加
