mysql master slave



slave


GRANT ALL PRIVILEGES ON *.* TO 'repl'@'192.168.1.3' IDENTIFIED BY 'repl' WITH GRANT OPTION;



[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
server_id=10
lower_case_table_names=1
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid


解决办法二、

首先停掉Slave服务：slave stop
到主服务器上查看主机状态：
记录File和Position对应的值

进入master

mysql> show master status;
+----------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+----------------------+----------+--------------+------------------+
| localhost-bin.000094 | 33622483 | | |
+----------------------+----------+--------------+------------------+
1 row in set (0.00 sec)



slave手动同步：

mysql> change master to master_host='192.168.1.3', master_user='repl',master_password='repl', master_port=3306, master_log_file='mysql-bin.000003', master_log_pos=671 ;
1 row in set (0.00 sec)
mysql> slave start;





master 上   show master status;    empty ??
server-id               = 1

datadir = /var/lib/mysql
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/var/mysql-relay-bin.index
log-error = /var/lib/mysql/mysql.err
master-info-file = /var/lib/mysql/mysql-master.info
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
log-bin = /var/lib/mysql/mysql-bin
