mariadb master and salve configure

mariadb master and salve configure

主从复制配置：

master：192。168.8.200
salve：192.168.8.201

主服务器配置：

主服务器需要启动二进制日志，主服务器每次数据的改变，都会记录到二进制日志；
配置主服务my.cnf文件；
[root@localhost data]# egrep -v "^$|^#" /etc/my.cnf
datadir = /mydata/data
skip_name_resolve = ON     //跳过域名解析
innodb_file_per_table = ON   //innodb使用独立表空间；
log-bin=mysql-bin			//启动二进制日志
binlog_format=mixed			//日志滚动方式；
server-id	= 1             //唯一id
创建可复制权限账号：
MariaDB [(none)]> grant replication slave,replication client on *.* to 'glq'@'192.168.%.%' identified by '123123';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> show master status;     //查看二进制日志文件file和postion，需要在slave制定复制日志信息；
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |

从服务器配置：
[root@localhost ~]# egrep -v "^$|^#" /etc/my.cnf
skip_name_resolve = ON
innodb_file_per_table = ON
datadir =  /mydata/data
relay-log = relay-log		//开启中继日志；
relay-log = relay-log.index
log-bin=mysql-bin
binlog_format=mixed
server-id	= 2
[root@localhost ~]# service mysqld restart
MariaDB [(none)]> change master to master_host='192.168.8.200',master_user='glq',master_password='123123',master_log_file='mysql-bin.000005',master_log_pos='245';    //设置复制线程，指定master password，user，二进制日志信息；

MariaDB [(none)]> start slave;     启动从server
MariaDB [(none)]> show slave statusG

在主服务器创建数据库，插入数据
MariaDB [(none)]> create database testdb;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> use testdb;
Database changed
MariaDB [testdb]> create table GEELY(id int unsigned not null auto_increment primary key,name char(20) not null,cardID varchar(10));
Query OK, 0 rows affected (0.01 sec)

MariaDB [testdb]> desc GEELY
    -> ;
