Mariadb,添加第四个Galera节点失败

galera database-replication cluster-computing mariadb mysql

Dora · 技术社区 · 7 年前

我有三个 node 在过去的几个月里,安装和运行都很完美。最近我想再加一个 节点 在另一个地方,但不知怎么的,我一直在犯错。

一开始,我只是按照这个教程(几个月前我第一次在这里设置) https://www.howtoforge.com/tutorial/how-to-install-and-configure-galera-cluster-on-ubuntu-1604/ 我没有从头开始所有的节点,我只需要找到 /mysql/conf.d/galera.cnf 其他三个 nodes 我添加了新的 节点 IP进入前三个。所以对于第四个我有 /etc/mysql/conf.d/galera.cnf 设置为…

[mysqld]
binlog_format=ROW
default-storage-engine=innodb
innodb_autoinc_lock_mode=2
bind-address=0.0.0.0
# Galera Provider Configuration
wsrep_on=ON
wsrep_provider=/usr/lib/galera/libgalera_smm.so
# Galera Cluster Configuration
wsrep_cluster_name="galera_cluster"
wsrep_cluster_address="gcomm://node1_ip,node2_ip,node3_ip,node4_ip"

# Galera Synchronization Configuration
wsrep_sst_method=rsync

# Galera Node Configuration
wsrep_node_address="xx.xx.xxx.xxx"
wsrep_node_name="Node4"

不知怎的,我得到了这个巨大的错误,

对于旧的3节点MARIAB版本,P.S为101.29,新节点为101.33。

提前谢谢你的建议。
