我已经通过这里的说明安装了mariadb 10.1：
https://mariadb.com/kb/en/mariadb/yum/#installing-mariadb-galera-cluster-with-yum
但是当我运行服务器：
sudo service mysql start --wsrep-new-cluster 该服务器不作为cluser运行：
MariaDB [(none)]> show status like 'wsrep%'; +--------------------------+----------------------+ | Variable_name | Value | +--------------------------+----------------------+ | wsrep_cluster_conf_id | 18446744073709551615 | | wsrep_cluster_size | 0 | | wsrep_cluster_state_uuid | | | wsrep_cluster_status | Disconnected | | wsrep_connected | OFF | | wsrep_local_index | 18446744073709551615 | | wsrep_provider_name | | | wsrep_provider_vendor | | | wsrep_provider_version | | | wsrep_ready | ON | +--------------------------+----------------------+
但是我没有碰到my.cnf，就像没有提到的说明一样。 我需要额外做些什么吗？
我的MariaDB版本是
mysql Ver 15.1 Distrib 10.1.9-MariaDB, for Linux (x86_64) using readline 5.1
我已经解决了这个问题，我正在使用centos7，我不得不：
1.）把这个添加到/etc/my.cnf.d/server.cnf
[mysqld] bind-address=0.0.0.0 [galera] wsrep_on=ON wsrep_provider=/usr/lib64/galera/libgalera_smm.so binlog_format=ROW wsrep_cluster_address='gcomm://' wsrep_cluster_name='galera_cluster' wsrep_node_name='node1'
2.）我必须禁用selinux和firewalld才能让其他节点连接到群集。 （我知道生产使用你应该处理selinux和防火墙的规则，但在我的情况下，这是一个本地机器上的testing，所以如果你用它来正确处理这个）
3.）在连接节点中用/etc/my.cnf.d/server.cnf指定：
[mysqld] bind-address=0.0.0.0 [galera] wsrep_on=ON wsrep_provider=/usr/lib64/galera/libgalera_smm.so binlog_format=ROW wsrep_cluster_address='gcomm://ip_of_the_master,ip_of_other_nodes' wsrep_cluster_name='galera_cluster' wsrep_node_name='nodeX'
然后启动mysql服务。
现在我的集群看起来像这样：
