mysql 存储过程中definer和invoker详解

在Ubuntu Server上实现MySQL Master/Slave设置。

1. Set up a replication user

grant replication slave on *.* TO 'repl'@'%' identified by 'repl';

2. Change Master's my.cnf under section '[mysqld]'

server-id               = 1
log_bin                 = /var/log/mysql/mysql-bin.log

3. Restart service

4. Check the master status:

mysql> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000001
Position: 314
Binlog_Do_DB:
Binlog_Ignore_DB:
1 row in set (0.00 sec)

5. Change Slave's my.cnf under section '[mysqld]'

server-id               = 2

6. Change Slave's master

change master to master_host='192.168.1.161', master_user='repl', master_password='repl';

7. Check slave status:

mysql> show slave status\G
