mysql 5.7 GTID如何實現(xiàn)主從配置

這篇文章給大家分享的是有關mysql 5.7 GTID如何實現(xiàn)主從配置的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。

binlog-format：二進制日志的格式，有row、statement和mixed幾種類型；需要注意的是：當設置隔離級別為READ-COMMITED必須設置二進制日志格式為ROW，現(xiàn)在MySQL官方認為STATEMENT這個已經(jīng)不再適合繼續(xù)使用；但mixed類型在默認的事務隔離級別下，可能會導致主從數(shù)據(jù)不一致；

log-slave-updates、gtid-mode、enforce-gtid-consistency、report-port和report-host：用于啟動GTID及滿足附屬的其它需求；

master-info-repository和relay-log-info-repository：啟用此兩項，可用于實現(xiàn)在崩潰時保證二進制及從服務器安全的功能；

sync-master-info：啟用之可確保無信息丟失；

slave-paralles-workers：設定從服務器的SQL線程數(shù)，根據(jù)cpu核數(shù)設定；0表示關閉多線程復制功能；

binlog-checksum、master-verify-checksum和slave-sql-verify-checksum：啟用復制有關的所有校驗功能；

binlog-rows-query-log-events：啟用之可用于在二進制日志記錄事件相關的信息，可降低故障排除的復雜度；

log-bin：啟用二進制日志，這是保證復制功能的基本前提；

server-id：同一個復制拓撲中的所有服務器的id號必須惟一。

report-host：

The host name or IP address of the slave to be reported to the master during slave registration. This value appears in the output of SHOW SLAVE HOSTS on the master server.

report-port:

The TCP/IP port number for connecting to the slave, to be reported to the master during slave registration.

master-info-repository:

The setting of this variable determines whether the slave logs master status and connection information to a FILE (master.info), or to a TABLE (mysql.slave_master_info)

relay-log-info-repository：

This option causes the server to log its relay log info to a file or a table.

log_slave_updates：

Whether updates received by a slave server from a master server should be logged to the slave's own binary log. Binary logging must be enabled on the slave for this variable to have any effect.

參數(shù)：

把master.info 和relay.info 保存在表中，默認是myisam引擎，官方建議修改為innodb

mysql> use mysql;

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

mysql> alter table slave_master_info engine=innodb;

Query OK, 0 rows affected (0.29 sec)

Records: 0  Duplicates: 0  Warnings: 0

mysql> alter table slave_relay_log_info engine=innodb;

Query OK, 0 rows affected (0.07 sec)

Records: 0  Duplicates: 0  Warnings: 0

mysql> alter table slave_worker_info engine=innodb;

Query OK, 0 rows affected (0.13 sec)

Records: 0  Duplicates: 0  Warnings: 0

忽略過濾表：

配置文件，需要重啟

replicate-ignore-table=test.t1

在線動態(tài)修改，無需重啟

CHANGE REPLICATION FILETER REPLICATE_DO_DB=(DB1,DB2);

CHANGE REPLICATION FILETER REPLICATE_IGNORE_DB=(DB1,DB2);

CHANGE REPLICATION FILETER REPLICATE_DO_TABLE=(DB1.T1);

CHANGE REPLICATION FILETER REPLICATE_IGNORE_TABLE=(DB1.T1);

CHANGE REPLICATION FILETER REPLICATE_WILD_DO_TABLE=(DB1.T%);

CHANGE REPLICATION FILETER REPLICATE_WILD_IGNORE_TABLE=(DB%.T%);

CHANGE REPLICATION FILETER REPLICATE_REWRITE_DB=(FROM_DB,TO_DB);
