1. Mysql installation
Refer to http://blog.itpub.net/28536251/viewspace-2138854 to install Mysql on both nodes.
2. Master node configuration
(1) modify the configuration file
[root@dbrac16 ~] # vim / etc/my.cnf
[mysqld]
Datadir=/usr/local/mysql/data
Socket=/usr/local/mysql/mysql.sock
User=mysql
Symbolic-links=0
Character-set-server=utf8
Server-id = 8416
Log-bin=/usr/local/mysql/data/mysql-bin
Binlog_format=mixed
Slow-query-log
Long_query_time=3
Log-output=TABLE
Expire_logs_days = 7
Event_scheduler=1

Innodb_log_file_size=536870912
Innodb_buffer_pool_size=1073741824
Max_binlog_size=1073741824
Log_bin_trust_function_creators=1
Innodb_stats_on_metadata=0
Max_connect_errors = 1000000
Max_connections = 5000

[mysqld_safe]
Log-error=/var/log/mysqld.log
Pid-file=/usr/local/mysql/my.pid
[client]
Socket=/usr/local/mysql/mysql.sock
[mysql]
Prompt= (\ u @\ h) [\ d]\ _
(2) restart Mysql
[root@dbrac16 ~] # / etc/init.d/mysqld restart
Shutting down MySQL. SUCCESS!
Starting MySQL. SUCCESS!
(3) create a replication user
(root@localhost) [(none)] GRANT REPLICATION SLAVE ON *. * TO 'repl'@'10.163.84.%' IDENTIFIED BY' repl'
Query OK, 0 rows affected, 1 warning (0.06 sec)
(root@localhost) [(none)] flush privileges
Query OK, 0 rows affected (0.08 sec)
(4) obtain log information
(root@localhost) [(none)] show master status
+-+
| | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | |
+-+
| | mysql-bin.000002 | 154 | |
+-+
1 row in set (0.01 sec)
3. Slave node configuration
(1) modify the configuration file
[root@dbrac17 ~] # vim / etc/my.cnf
[mysqld]
Datadir=/usr/local/mysql/data
Socket=/usr/local/mysql/mysql.sock
User=mysql
Symbolic-links=0
Character-set-server=utf8
Server-id=8417
Slow-query-log
Long_query_time=3
Log-output=TABLE
Expire_logs_days = 7
Event_scheduler=1
Innodb_file_per_table=1
Innodb_log_file_size=536870912
Innodb_buffer_pool_size=1073741824
Max_binlog_size=1073741824
Log_bin_trust_function_creators=1
Innodb_stats_on_metadata=0
Max_connect_errors = 1000000
Max_connections = 5000
Skip_name_resolve = 1
Explicit_defaults_for_timestamp=true
[mysqld_safe]
Log-error=/var/log/mysqld.log
Pid-file=/usr/local/mysql/my.pid
[client]
Socket=/usr/local/mysql/mysql.sock
[mysql]
Prompt= (\ u @\ h) [\ d]\ _
(2) Delete auto.cnf file
[root@dbrac17 ~] # rm / usr/local/mysql/data/auto.cnf
Rm: remove regular file `/ usr/local/mysql/data/auto.cnf'? Y
(3) restart Mysql
[root@dbrac17 ~] # / etc/init.d/mysqld restart
Shutting down MySQL. SUCCESS!
Starting MySQL. SUCCESS!
(4) configure the connection to the primary node
(root@localhost) [(none)] CHANGE MASTER TO MASTER_HOST='10.163.84.16',MASTER_PORT=3306,MASTER_USER='repl',MASTER_PASSWORD='repl',MASTER_LOG_FILE='mysql-bin.000002',MASTER_LOG_POS=154
Query OK, 0 rows affected, 2 warnings (0.05 sec)
(5) start replication and check the status
(root@localhost) [(none)] start slave
Query OK, 0 rows affected (0.03 sec)
(root@localhost) [(none)] show slave status\ G

4. Test
(1) the master node creates a library, tables and inserts data
(root@localhost) [(none)] create database test
Query OK, 1 row affected (0.01sec)
(root@localhost) [(none)] use test
Database changed
(root@localhost) [test] create table tb1 (id int)
Query OK, 0 rows affected (0.07 sec)
(root@localhost) [test] insert into tb1 values (1)
Query OK, 1 row affected (0.04 sec)
(2) View from the node
(root@localhost) [(none)] use test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with-A
Database changed
(root@localhost) [test] select * from tb1
