2 三臺機器搭建PXC
192.168.10.159
192.168.10.160
192.168.10.161
2.1 第一節點
2.1.1參數
/etc/my.cnf
wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc1 wsrep_node_address=192.168.10.159 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 |
2.1.2第一個節點啓動
systemctl start [email protected]
2.1.3創建用戶
在error log中找到root@localhost的temporary password
grep temp mysql_error.log
CREATE USER 'sstuser'@'localhost' IDENTIFIED BY 'passw0rd'; GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO'sstuser'@'localhost'; FLUSH PRIVILEGES; |
2.2 第二節點
server_id需要修改
wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc2 wsrep_node_address=192.168.10.160 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 |
啓動：systemctl start mysql
2.3 第三節點
server_id需要修改
wsrep_provider=/usr/lib64/galera3/libgalera_smm.so wsrep_cluster_name=pxc wsrep_cluster_address='gcomm://192.168.10.159,192.168.10.160,192.168.10.161' wsrep_node_name=pxc3 wsrep_node_address=192.168.10.161 wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:passw0rd pxc_strict_mode=ENFORCING binlog_format=ROW default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 |
啓動：systemctl start mysql
