MYSQL 日志(log-bin)备份

1.启动日志

mysqld_safe --log-bin --user=mysql &

2.修改my.cnf文件

[mysqld]
server-id=1
log-bin=master 日志名称
log-bin-index=master
binlog_format=statement

3.查看是否启动了binlog日志

mysql> set binlog_rows_query_log_events=1;

4.重新启动mysqld

systemctl restart systemd


mysql> show binlog events G
*************************** 1. row ***************************
   Log_name: 131-bin.000001
        Pos: 4
 Event_type: Format_desc
  Server_id: 1
End_log_pos: 106
       Info: Server ver: 5.1.34-log, Binlog ver: 4
1 row in set (0.00 sec)

5.创建库 　　创建表 　　刷新日志 　　flush logs 　　插入数据　　物理删除库

mysql > create database upup;
mysql > use upup;
mysql > create table t1(id int,name char(10));
mysql > flush logs
mysql > insert into t1 values(1 ,'ww');
mysql > drop database upup;

6.杀mysql进程(关闭2进制binlog)

pkill mysqld



[mysqld]
secure_file_priv =
#server-id=1
#log-bin=master
#log-bin-index=master
#binlog_format=statement

7.初始化数据库

[root@localhost mysql]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data 

8.启动mysql

systemctl restart mysqldd

9.恢复全备

 mysql -u root -p123456 < /backup/all.sql

10.恢复binlog

 mysqlbinlog /backup/master.000001 | mysql -u root -p123456
