有没有可能用mariadb设置多主多从的galera？

[galera]
wsrep_on=ON
wsrep_provider=/usr/lib/galera/libgalera_smm.so
wsrep_cluster_name="my_cluster"
wsrep_cluster_address="gcomm://node1_ip,node2_ip,node3_ip"
wsrep_node_address="current_node_ip"
wsrep_node_name="current_node_name"

sudo systemctl start mariadb
sudo mysql_secure_installation
sudo mysql -u root -p -e "CREATE USER 'galera'@'%' IDENTIFIED BY 'password';"
sudo mysql -u root -p -e "GRANT ALL PRIVILEGES ON *.* TO 'galera'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;"
sudo mysql -u root -p -e "FLUSH PRIVILEGES;"
sudo mysql -u root -p -e "SET GLOBAL wsrep_cluster_address='gcomm://';"
sudo mysql -u root -p -e "SET GLOBAL wsrep_provider_options='pc.bootstrap=1';"
sudo mysql -u root -p -e "CREATE DATABASE mydb;"
sudo mysql -u root -p -e "CREATE TABLE mydb.mytable (id INT PRIMARY KEY, name VARCHAR(20));"
sudo mysql -u root -p -e "INSERT INTO mydb.mytable (id, name) VALUES (1, 'John');"

sudo systemctl start mariadb
sudo mysql -u root -p -e "SET GLOBAL wsrep_cluster_address='gcomm://node1_ip,node2_ip,node3_ip';"
