MariaDB Galera Cluster的配置测试

参考的https://fykuan.hsnuer.net/blog/2015/01/23/debian-%E4%B8%8A%E5%AE%89%E8%A3%9D-mariadb-galera-cluster/

ip列表

192.168.1.119（主）
192.168.1.115

主从都装

sudo apt-get install python-software-properties
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xcbcb082a1bb943db
sudo add-apt-repository 'http://mirrors.ustc.edu.cn/mariadb/repo/10.1/debian/ wheezy main'

sudo apt-get update
sudo apt-get install mariadb-galera-server

配置用户

mysql -uroot -p
mysql> insert into mysql.user(host,user,password) values('localhost','repuser','123456');
mysql> GRANT USAGE ON *.* TO cluster@'%' IDENTIFIED BY 'abcdefg'; 
mysql> GRANT ALL PRIVILEGES ON *.* TO cluster@'%'; 
mysql> GRANT USAGE ON *.* TO cluster@'localhost' IDENTIFIED BY 'abcdefg'; 
mysql> GRANT ALL PRIVILEGES ON *.* TO cluster@'localhost'; 
mysql> FLUSH ALL PRIVILEGES;

master上

sudo cp /usr/share/mysql/wsrep.cnf /etc/mysql/conf.d

改成下面

[MYSQLD]
wsrep_provider=/usr/lib/galera/libgalera_smm.so
binlog_format=ROW
wsrep_cluster_name="my_cluster"
wsrep_node_address=192.168.1.119

#下面这行不能缺
wsrep_cluster_address="gcomm://"
wsrep_sst_method=rsync

#这是用来同步的用户
wsrep_sst_auth=repuser:123456

从机

[MYSQLD]
wsrep_provider=/usr/lib/galera/libgalera_smm.so
binlog_format=ROW
wsrep_cluster_name="my_cluster"
wsrep_node_address=192.168.1.115

wsrep_cluster_address="gcomm://192.168.1.119"
wsrep_sst_method=rsync

#这是用来同步的用户
wsrep_sst_auth=repuser:123456

测试可以多主写入，主挂掉，从自动变主
