MySQL复制--最快的从库搭建方法（tar包）

-- 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;
