因线路或安全需要我们不得不考虑mysql的备份,特把mysql数据备份的方法整理下。
测试环境.基本上数据是瞬间同步,希望对大家有帮助
RedHat ES 3 update 3
MYSQL 5.0.15
MYSQL数据同步备份
A服务器: 192.168.1.2 主服务器master
B服务器: 192.168.1.3 副服务器slave
A服务器设置
#mysql –u root –p
mysql>GRANT FILE ON *.* TO backup@192.168.1.3 IDENTIFIED BY ‘1234';
mysql>exit
上面是Master开放一个账号backup密码1234给IP:192.168.1.3有档案处理的权限
mysqladmin –u root –p shutdown
导出Master的数据库到slave的机器,可以选择导出需要同步的数据库
在A机器上修改/etc/my.cnf
在[mysqld]区段内加入参数
log-bin=mysql-bin
server-id=1
binlog_do_db = gbbbs(要同步的数据库)
binlog_ignore_db = mysql,test,information_schema (不需要同步的库,5.0 有information_schema这个库)
sql-bin-update-same
重启A服务器mysql
B服务器设置
设定/etc/my.cnf
在[mysqld]区段加入
server-id = 2 (如果还有slave用户,他们的ID也随之增加,如server-id=3)
master-host = 192.168.112.71
master-user = backup
master-password = 1234
replicate-do-db = gbbbs
#replicate-do-db = database2
log-warnings
master-port=3306
master-connect-retry = 60
重启B服务器的MYSQL
在数据库的文件夹里有master.info文件,用来查看同步信息
其实就是MYSQL Replication

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
