MYSQL主、从服务器配置及错误处理
来源:互联网 发布:农村淘宝名片 编辑:程序博客网 时间:2024/06/11 21:59
一. MySQL主服务器配置
1.建立用户
grant replication slave on *.* to gd@192.168.6.101 identified by '123456';
# grant replication slave on *.* to ‘用户名’@'主机’ identified by ‘密码’;
# 可在B Slave上做连接测试: mysql -h 192.168.8.100 -ugd -p
2.编辑配置文件/etc/my.cnf
# 确保有如下行
server-id = 1
log-bin=mysql-bin
binlog-do-db=test
binlog-ignore-db=mysql
#binlog-do-db=需要备份的数据库名,可写多行
#binlog-ignore-db=不需要备份的数据库名,可写多行
二.MySQL从服务器配置
编辑/etc/my.cnf
server-id=2
log-bin=mysql-bin
master-host=192.168.6.100
master-user=gd
master-password=123456
master-port=3306
replicate-do-db=test
# replicate-do-db=test 需要备份的数据库名
# replicate-ignore-db=mysql 忽略的数据库
# master-connect-retry=60 如果从服务器发现主服务器断掉,重新连接的时间差(秒)
修改配置需要注意,需要删除从服务器上的/var/lib/mysql/master.info文件
[root@CentOS-2 ~]# rm -f /var/lib/mysql/master.info
[root@CentOS-2 ~]# /etc/init.d/mysql restart
再次打开/var/lib/mysql/master.info ,可以看到以下的信息:
14
4
192.168.6.100
gd
123456
3306
60
0
在 192.168.6.101 上,用帐号 gd 登录,查看 主服务器的 状态:
mysql> show master status;
ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation
在 192.168.6.100 上,给 gd@192.168.6.101 分配权限:
mysql> select * from mysql.user where user='gd';

1.建立用户
grant replication slave on *.* to gd@192.168.6.101 identified by '123456';
# grant replication slave on *.* to ‘用户名’@'主机’ identified by ‘密码’;
# 可在B Slave上做连接测试: mysql -h 192.168.8.100 -ugd -p

二.MySQL从服务器配置
编辑/etc/my.cnf

master-user=gd
master-password=123456

# master-connect-retry=60 如果从服务器发现主服务器断掉,重新连接的时间差(秒)
修改配置需要注意,需要删除从服务器上的/var/lib/mysql/master.info文件
[root@CentOS-2 ~]# rm -f /var/lib/mysql/master.info
