Mariadb
SST 未在 MariaDB Galera 集群上的新節點上啟動
我有兩台MariaDB 伺服器，我想用它來創建一個新的MariaDB Galera 集群：
- 伺服器mysql1，帶有一些數據並配置為供體
- 伺服器mysql2，無數據且
/var/lib/mysql為空，我想作為新節點加入新集群- MariaDB 版本：10.2.13
- SST 方法：xtrabackup-v2
mysql1 上的 MariaDB 已啟動並執行，我可以瀏覽數據庫，一切似乎都很好：
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問題是，如果我在新節點 mysql2 上啟動 MariaDB，SST 程序不會啟動並且新節點不會加入集群。
這是嘗試加入集群時mysql2上的錯誤：
