這篇文章給大家分享的是有關(guān) mysql 5.7 GTID 如何實(shí)現(xiàn)主從配置的內(nèi)容。丸趣 TV 小編覺得挺實(shí)用的,因此分享給大家做個(gè)參考,一起跟隨丸趣 TV 小編過來看看吧。
binlog-format:二進(jìn)制日志的格式,有 row、statement 和 mixed 幾種類型;需要注意的是:當(dāng)設(shè)置隔離級(jí)別為 READ-COMMITED 必須設(shè)置二進(jìn)制日志格式為 ROW,現(xiàn)在 MySQL 官方認(rèn)為 STATEMENT 這個(gè)已經(jīng)不再適合繼續(xù)使用;但 mixed 類型在默認(rèn)的事務(wù)隔離級(jí)別下,可能會(huì)導(dǎo)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(dòng) GTID 及滿足附屬的其它需求;
master-info-repository 和 relay-log-info-repository:啟用此兩項(xiàng),可用于實(shí)現(xiàn)在崩潰時(shí)保證二進(jìn)制及從服務(wù)器安全的功能;
sync-master-info:啟用之可確保無信息丟失;
slave-paralles-workers:設(shè)定從服務(wù)器的 SQL 線程數(shù),根據(jù) cpu 核數(shù)設(shè)定;0 表示關(guān)閉多線程復(fù)制功能;
binlog-checksum、master-verify-checksum 和 slave-sql-verify-checksum:啟用復(fù)制有關(guān)的所有校驗(yàn)功能;
binlog-rows-query-log-events:啟用之可用于在二進(jìn)制日志記錄事件相關(guān)的信息,可降低故障排除的復(fù)雜度;
log-bin:啟用二進(jìn)制日志,這是保證復(fù)制功能的基本前提;
server-id:同一個(gè)復(fù)制拓?fù)渲械乃蟹?wù)器的 id 號(hào)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.

把 master.info 和 relay.info 保存在表中,默認(rèn)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

忽略過濾表:
