不停机xtrabackup创建slave节点(四)
ogfile1 mysql xtrabackup_binary xtrabackup_checkpoints
[mysql@master2 3307]$ ls data/test/
j1.frm j1.ibd j2.MYD j2.MYI j2.frm t1.frm t1.ibd
?
?
3、创建复制环境专用账户
master: (system@localhost) [(none)]> grant replication slave on *.* to 'repl'@'10.1.1.%' identified by 'replsafe'; Query OK, 0 rows affected (0.09 sec) (system@localhost) [(none)]> select user,host from mysql.user; +--------+-----------+ | user | host | +--------+-----------+ | dcw | % | | repl | 10.1.1.% | | test | 10.1.1.% | | system | localhost | | xtrabk | localhost | +--------+-----------+
?
?
4、配置slave节点初始化参数文件
[mysql@master1 3306]$ scp my.cnf 10.1.1.18:/data/mysqldata/3307 [mysql@master2 ~]$ vim /data/mysqldata/3307/my.cnf server-id=2 [mysql@master2 ~]$ sed -i 's/3306/3307/g' /data/mysqldata/3307/my.cnf [mysql@master2 ~]$ mysqld_safe --defaults-file=/data/mysqldata/3307/my.cnf & slave节点少创建了tmp和binlog两个文件夹 [mysql@master2 3307]$ mkdir tmp [mysql@master2 3307]$ mkdir binlog [mysql@master2 3307]$ ls binlog data lost+found my.cnf mysql-error.log tmp 启动数据库 [mysql@master2 3307]$ mysqld_safe --defaults-file=/data/mysqldata/3307/my.cnf &
?

5、配置slave节点复制环境
查看备份集信息：
[mysql@master2 3307]$ cat data/xtrabackup_binlog_info mysql-bin.000011 812 [mysql@master2 3307]$ mysql -usystem -p'5ienet.com' -S /data/mysqldata/3307/mysql.sock (system@localhost) [(none)]> change master to master_host='10.1.1.17',master_port=3306,master_user='repl',master_password='replsafe',master_log_file='mysql-bin.000011',master_log_pos=812; Query OK, 0 rows affected, 2 warnings (0.09 sec) (system@localhost) [(none)]> start slave; Query OK, 0 rows affected (0.14 sec)
?
?
6、检查
(system@localhost) [(none)]> start slave;
Query OK, 0 rows affected (0.14 sec)
(system@localhost) [(none)]> show slave status\G
