![无法向 Galera Cluster 添加更多服务器 --> [错误] /usr/sbin/mysqld: 未知选项‘--’。](https://linux22.com/image/691609/%E6%97%A0%E6%B3%95%E5%90%91%20Galera%20Cluster%20%E6%B7%BB%E5%8A%A0%E6%9B%B4%E5%A4%9A%E6%9C%8D%E5%8A%A1%E5%99%A8%20--%3E%20%5B%E9%94%99%E8%AF%AF%5D%20%2Fusr%2Fsbin%2Fmysqld%3A%20%E6%9C%AA%E7%9F%A5%E9%80%89%E9%A1%B9%E2%80%98--%E2%80%99%E3%80%82.png)
我尝试在我的 Debian 8 服务器上使用 Galera 设置 MariaDB 集群。
当我尝试将服务器添加到集群中已存在的服务器时：
systemctl start mysql
我收到此错误：
mariadb.service 的作业失败。请参阅“systemctl status mariadb.service”和“journalctl -xn”了解详情。
我在输出中找到了这一行journalctl -xn：
Okt 12 09:35:29 node2 sh[5272]: 2016-10-12 9:35:27 3045435776 [ERROR] /usr/sbin/mysqld: unknown option '--.'
于是我/etc/init.d/mysql用打开nano，但却找不到--任何地方。
有人知道如何解决这个问题吗？
结果如下systemctl status mariadb.service：

答案1
您需要定义节点的地址，例如：
# this server ip, change for each server
wsrep_node_address="192.168.2.162"
请注意在测试时禁用所有防火墙，以防防火墙阻止节点之间的连接
