1.準備兩臺裝好mysql的機器
mysql單機安裝步驟請參考https://my.oschina.net/qbj/blog/1850086
我的兩臺主機分別爲 10.20.4.58 和10.20.4.59
58爲mater機器 59爲slave機器
在msater上的mysql創建一個用戶
mysql> grant replication slave on *.* to 'repl'@'10.20.4.59' identified by '{yourPassword}';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
{yourPassword} 自己設定的密碼
2. 修改master(58)的my.cnf
server-id=58
log-bin=mysqlbin-log
binlog_format=mixed
read-only=0
binlog-ignore-db=information_schema
binlog-ignore-db=mysql
binlog-ignore-db=performance_schema
binlog-ignore-db=sys
auto_increment_increment=2
auto_increment_offset=1
重啓mysql服務
3. 修改slave(59)的my.cnf
server-id=59
log-bin=mysqlbin-log
binlog_format=mixed
replicate-ignore-db=information_schema
replicate-ignore-db=mysql
replicate-ignore-db=performance_schema
replicate-ignore-db=sys
log-slave-updates=ON
重啓mysql服務
4 . 查看master機器的狀態,在mysql下運行
mysql> show master status\G
*************************** 1. row ***************************
File: mysqlbin-log.000003
Position: 1270
Binlog_Do_DB:
Binlog_Ignore_DB: information_schema,mysql,performance_schema,sys
Executed_Gtid_Set:
1 row in set (0.00 sec)
記住 Position和File
5. 在slave機器配置master的信息
mysql> CHANGE MASTER TO MASTER_HOST='10.20.4.58', MASTER_USER='repl', MASTER_PASSWORD='{yourPassword}', MASTER_LOG_FILE='mysqlbin-log.000003', MASTER_LOG_POS=1270;
Query OK, 0 rows affected, 2 warnings (0.02 sec)
查看slave狀態,如果 Slave_IO_Running和 Slave_SQL_Running都爲Yes,說明配置就是成功了。
mysql> show slave status\G
*************************** 1. row ***************************

6. 驗證
在master上創建一個表,看是否能夠正常同步到slave機器上。
