Der folgende Editor bringt Ihnen einen Artikel MySQL-Konfigurationsschritte für die Gruppenreplikation (empfohlen). Der Herausgeber findet es ziemlich gut, deshalb werde ich es jetzt mit Ihnen teilen und es allen als Referenz geben. Folgen wir dem Editor, um einen Blick darauf zu werfen.
MySQL-Group-Replication ist eine neue Funktion, die in der MySQL-Version 5.7.17 entwickelt wurde. Sie erreicht eine starke Konsistenz zwischen Master und Slave.
Aber vorerst Der Hauptgrund ist, dass die Leistung nicht sehr gut ist.
【1】Stellen Sie sicher, dass die aktuelle MySQL-Datenbankversion 5.7.17 und höher ist
/usr/local/mysql/bin/mysqld --version /usr/local/mysql/bin/mysqld Ver 5.7.17 for linux-glibc2.5 on x86_64 (MySQL Community Server (GPL))
【 2 】Die experimentelle Umgebung besteht darin, drei MySQLs auf einem Host zu installieren. Die drei bilden eine Gruppenreplikationsgruppe
/tmp/4406.cnf. Der Inhalt lautet wie folgt:

[3]Initialisieren Sie drei Datenbankinstanzen
cd /usr/local/mysql/ ./bin/mysqld --defautls-file=/tmp/4406.cnf --datadir=/tmp/4406 --initialize-insecrue ./bin/mysqld --defautls-file=/tmp/5506.cnf --datadir=/tmp/5506 --initialize-insecrue ./bin/mysqld --defautls-file=/tmp/6606.cnf --datadir=/tmp/6606 --initialize-insecrue
[4]Konfigurieren Sie die erste Instanz der Gruppenreplikation
/usr/local/mysql/bin/mysqld --defaults-file=/tmp/4406.cnf &
mysql -h127.0.0.1 -uroot -P4406
-- 增加用户
set sql_log_bin=0;
create user rpl_user@'%' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'%';
create user rpl_user@'127.0.0.1' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'127.0.0.1';
create user rpl_user@'localhost' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'localhost';
set sql_log_bin=1;
-- 增加复制凭证
change master to
master_user='rpl_user',
master_password='123456'
for channel 'group_replication_recovery';
-- 安装组复制物件
install plugin group_replication soname 'group_replication.so';
-- 启动组复制
set global group_replication_bootstrap_group=on;
start group_replication;
set global group_replication_bootstrap_group=off;【5】Der Konfigurationsprozess der 5506-Instanz ist wie folgt:
/usr/local/mysql/bin/mysqld --defaults-file=/tmp/5506.cnf &
mysql -h127.0.0.1 -uroot -P5506
-- 增加用户
set sql_log_bin=0;
create user rpl_user@'%' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'%';
create user rpl_user@'127.0.0.1' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'127.0.0.1';
create user rpl_user@'localhost' identified by '123456';
grant replication slave,replication client on *.* to rpl_user@'localhost';
set sql_log_bin=1;
-- 增加复制凭证
change master to
master_user='rpl_user',
master_password='123456'
for channel 'group_replication_recovery';
-- 安装组复制物件
install plugin group_replication soname 'group_replication.so';
-- 启动组复制
start group_replication; # 注意这里不是初始化了，只要加入就行【6】Der Vorgang der 6606-Instanz ist der gleiche wie der der 5506. Der Vorgang ist der gleiche und die Konfiguration der Gruppenreplikation ist abgeschlossen.
