mysql RDS数据库恢复

[mysqld_multi]
mysqld = /usr/local/lnmp/mysql/bin/mysqld_safe
mysqladmin = /usr/local/lnmp/mysql/bin/bin/mysqladmin
user = root

[mysqld1]
port = 3306
socket = /tmp/mysql.sock
datadir = /date/lnmp/mysql

log-error = /date/lnmp/log1/mysql_error.log

[mysqld2]
port = 3307
socket = /tmp/mysql2.sock
datadir = /mysql2
pid-file = /mysql2/mysql.pid
log-error = /date/lnmp/log1/mysql_error2.log
innodb_data_file_path=ibdata1:200M:autoextend
innodb_log_files_in_group=2
innodb_log_file_size=1048576000       #这三行很重要，在/mysql2/mysql-my.cnf中有，复制过来就可以了，不然innodb表打不开

启动实例

/usr/local/lnmp/mysql/bin/mysqld_multi --defaults-file=/etc/my.cnf start 1

/usr/local/lnmp/mysql/bin/mysqld_multi --defaults-file=/etc/my.cnf start 2 

停止实例方法

kill -9 `ps -ef | grep 3307 | grep -v grep | awk ‘{print $2}‘ | xargs`

修改mysql数据库用户名

mysql -uroot -proot -S /tmp/mysql2.sock

grant all on *.* to root@‘localhost‘ identified by ‘password‘

4,以上第3步是针对一台多个实例，如果就一个实例的话就不需要那么麻烦了，第3步就是如下了：

vi /etc/my.cnf

[mysqld]

innodb_data_file_path=ibdata1:200M:autoextend
innodb_log_files_in_group=2
innodb_log_file_size=1048576000     #只要加这三行就可以了
