Question

我无法在centos 7中配置galera集群。在这里，我按照https://mariadb.com/resources/blog/getting-started-with-mariadb-galera-and-mariadb-maxscale-on-centos/的建议进行了以下操作。这是我的操作系统详细信息：[root @ localhost my.cnf.d]＃cat / etc / redhat-release CentOS Linux版本7.4.1708（核心）如链接中所述，对server.cnf文件进行以下更改。发出galera_new_cluster命令后，仍然可以看到群集尚未启动。让我惊讶的是，我发现server.cnf文件中的任何更改都不会影响maria db，如果如果我写出juck data，仍然在发出galera_new_cluster之后，maria db starts，状态看起来像 ariaDB [（none）]>显示类似'wsrep％'的全局状态； </ p>

Answer 1

检查文件/etc/my.cnf 应该是这样的：

 #
 # This group is read both both by the client and the server
 # use it for options that affect everything
 # [client-server]

 #
 # include all files from the config directory

 includedir /etc/my.cnf.d

Answer 2

这是重新安装后才发现未引用/etc/my.cnf.d/的对我有用的方法，而是在my.cnf中添加了galera配置，并且有效样本my.cnf：

 #
 [galera]
 binlog_format=row
 default-storage-engine=InnoDB

 innodb_autoinc_lock_mode=2

 bind-address=0.0.0.0

 wsrep_on=ON

 wsrep_provider=/usr/lib64/galera/libgalera_smm.so

 wsrep_cluster_address="gcomm://172.16.1.2,172.16.1.3” # include all of the master node ips



 ## Galera Cluster Configuration

 wsrep_cluster_name=“test_cluster”



 ## Galera Synchronization Configuration

 wsrep_sst_method=rsync



 ## Galera Node Configuration

 wsrep_node_address=“172.16.1.3” 
 wsrep_node_name=“node-0”
