加莱拉引导失败，没有错误

我整个周末一直在试图让Galera群集运行起来，在CentOS 7上使用MariaDB 10.1.5（其中包括Galera 25.3.9）。该服务器运行两个数据库实例，一个是本地的，一个是集群的一部分。

我已经多次完成了这个确切的设置，没有问题，但现在我无能为力了。

my.cnf：

[mysqld_multi] mysqld=/usr/bin/mysqld_safe --basedir=/usr user=mysql # # Server local DB # [mysqld1] mysqld=/usr/bin/mysqld_safe --basedir=/usr user=mysql port=3307 pid-file=/storage/local/mysqld.pid socket=/storage/local/mysqld.sock datadir=/storage/local log-error=/var/log/mariadb-local.log # # Server cluster DB # [mysqld2] wsrep_new_cluster wsrep_cluster_address=gcomm:// #wsrep_cluster_address="gcomm://172.16.1.91,172.16.1.94,172.16.1.95" wsrep_debug=1 query_cache_size=0 log-bin=/var/log/mariadb/cluster-bin.log binlog_format=ROW default_storage_engine=innodb innodb_autoinc_lock_mode=2 wsrep_provider=/usr/lib64/galera/libgalera_smm.so wsrep_cluster_name="MyApps" wsrep_node_address=172.16.1.91 wsrep_node_name="dbnode1" wsrep_sst_method=xtrabackup-v2 wsrep_sst_auth=sstuser:sstpass mysqld=/usr/bin/mysqld_safe --basedir=/usr user=mysql port=3306 pid-file=/storage/cluster/mysqld.pid socket=/storage/cluster/mysqld.sock datadir=/storage/cluster log-error=/var/log/mariadb-cluster.log 

当启动这个节点时，我在日志中得到这个：

这表明一切正常，但检查wsrepvariables显示， WSREP_READY = OFF ，任何尝试访问引擎返回

 ERROR 1047 (08S01): WSREP has not yet prepared node for application use 

日志看起来很好，没有错误（除了崩溃恢复，这是因为关机时间太长，可能是因为挂了什么），唯一让我担心的是

 WSREP: New COMPONENT: primary = yes, bootstrap = no, my_idx = 0, memb_num = 1 

我觉得奇怪，我引导群集，如果这不是bootstrap = yes ？
