Question

我在VMware VM上安装了ubuntu 16.04。然后我从mariadb网站添加了回购，我安装了最新版本的mariadb 10.1。

安装工作正常

然后我创建了一个文件

sudo nano /etc/mysql/conf.d/cluster.cnf

以下

[mysqld]

# Cluster node configurations
wsrep_cluster_address="gcomm://20.0.1.51"
wsrep_node_address="20.0.1.51"
innodb_buffer_pool_size=800M

# Mandatory settings to enable Galera
wsrep_on=ON
wsrep_provider=/usr/lib/galera/libgalera_smm.so
binlog_format=ROW
default-storage-engine=InnoDB
innodb_autoinc_lock_mode=2
innodb_doublewrite=1
query_cache_size=0
bind-address=0.0.0.0

# Galera synchronisation configuration
wsrep_sst_method=rsync

我只想引导第一个节点，然后添加新节点

所以我跑

sudo service mysql bootstrap

但是我收到了这个错误

我做错了什么？

Answer 1

它是系统化的东西。在具有systemd的系统上，应使用 galera_new_cluster 来引导新群集。 https://mariadb.com/kb/en/mariadb/systemd/

MariaDB Galera不会引导第一个节点
