MariaDB Galera Clusterの新しいノードでSSTが起動しない
2つのMariaDBサーバーを使用して、新しいMariaDB Galera Cluster：
- サーバーmysql1、一部のデータを含み、donorとして構成されています
- サーバーmysql2、データなし、
/var/lib/mysql空、これは新しいノードとして新しいクラスターに参加します - MariaDBのバージョン：10.2.13
- SSTメソッド：xtrabackup-v2
Mysql1のMariaDBが稼働しているので、データベースを参照できます。
root@mysql1:/etc/mysql/conf.d# ps ax|grep mysql
21494 pts/0 Sl 0:03 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib/mysql/plugin --user=mysql --wsrep_on=ON --wsrep_provider=/usr/lib/galera/libgalera_smm.so --skip-log-error --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306 --wsrep_start_position=580c1d7d-293a-11e8-bbc6-73374d41b35e:77
問題は、新しいノードmysql2でMariaDBを起動すると、SSTプロセスが起動せず、新しいノードがクラスターに参加しないことです。
これは、クラスターに参加しようとしたときのmysql2のエラーです：
