ubuntu-14.04 - 错误 Galer 集群 : Failed to read 'ready <addr>' from: wsrep_sst_rsync --role 'joiner'

Question

你可以帮助我吗..我是 mariadb 集群的新手。当我开发新的 galera 集群时，当我重新启动其中一个集群时出现错误:无法从以下位置读取“ready”:wsrep_sst_rsync --role 'joiner'

Thera 是五服务器

这是我的galera.cnf

[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="dev_cluster"
wsrep_cluster_address="gcomm://192.168.0.18,192.168.0.19,192.168.0.20,192.168.0.22,192.168.0.23"

# Galera Synchronization Configuration
wsrep_sst_method=rsync

# Galera Node Configuration
wsrep_node_address="192.168.0.20"
wsrep_node_name="galera_node5"

这是我的主人

192.168.0.18    galera_node01
192.168.0.19    galera_node04

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

这是错误

有人可以帮忙吗？

非常感谢

当我尝试使用日志文件中显示的参数手动运行 wsrep_sst_rsync 时，我发现了同样的问题并得到了解决方案。 就我而言，是: wsrep_sst_rsync --角色'加入者'--地址'10.0.1.82'--datadir'/var/lib/mysql/'--defaults-file'/etc/mysql/my.cnf'--defaults-group-suffix' ' --父'5048' ''

这表明有一个 rsync 进程已经在监听端口 4444。杀死它可以解决问题。
