笔记整理之 MySQL复制--最快的从库搭建方法（tar包）

最快的从库搭建方法0，准备从库第一次数据备份，临时锁所有表

开启窗口1：

mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)

mysql> show master status;         
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 |   194554 |              |                  |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

PS：这个窗口不能exit，要一直保持知道tar完包为止。

重新开一个shell窗口，去数据文件目录tar包
开启窗口2

[root@myfstv_21_11 data]# tar -zcvf mysqla1.tar.gz mysqla
tar -zcvf ```mysqla1.tar.gz mysqla  压缩完毕

切换到窗口1，执行解锁命令

mysql> unlock tables;             
Query OK, 0 rows affected (0.00 sec)mysql>

进入21.12，传输tar包

[root@myfstv_21_12 data]# scp xx.xx0.xx.11:/data/mysqla1.tar.gz ./

1，在/usr/local/mysqla/my.cnf里面添加

log-bin=/log/mysqla/mysql-bin
long_query_time = 1
slow_query_log
log_slow_queries=/log/mysqla/slow.log
max_binlog_size=1024M
binlog_cache_size=4M
max_binlog_cache_size=512M
binlog_format=mixed
log_slave_updates = 1
read_only=1
relay-log=relay-bin
relay-log-index=relay-bin

2，在xx.12上面mysqla上面执行

mysql> change master to master_user='repl', master_password='mb', master_host='xx.xx0.xx.11', master_log_file='mysql-bin.000003',master_log_pos=194554;
mysql> start slave;
mysql> show slave status\G;
