错误 WSREP`：gcs/src/gcs.cpp:gcs_open():1379:` 无法打开通道“test_cluster”

Question

我有三台要在其上安装 Galera 集群的服务器，我按照此链接进行安装和配置。但是当我想启动第一台服务器时，我收到了这个错误：

root@node107:/home/debian# service mysql start --wsrep-new-clusterping 
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.

和 ：

root@node107:/home/debian# journalctl -xn

这些是三个服务器的配置文件：

vim /etc/mysql/conf.d/cluster.cnf

服务器1：

[mysqld]

binlog_format=ROW
default-storage-engine=innodb
innodb_autoinc_lock_mode=2
query_cache_type=0

服务器 2：

服务器 3：

#wsrep_sst_auth=user:pass

# Galera Node Configuration
wsrep_node_address="192.168.120.117"
wsrep_node_name="node117"

我不明白我错过了什么。我该怎么办？

Answer 1

我们应该在以下参数中启动第一个节点my.cnf： wsrep_cluster_address="gcomm://192.168.120.107,192.168.120.111,192.168.120.117"

然后正常启动其他节点：

/etc/init.d/mysql start

第一个节点应该像其他节点一样正常启动。
