Question

我正在使用Ubuntu 16.04并通过AWS中的apt-get安装MySQL版本5.7。

之后，我通过official website使用apt-get install galera-3 galera-arbitrator-3 mysql-wsrep-5.6

跟踪{{3}}中的文档，设法将MySQL升级到Galera群集

之后我将文件/etc/mysql/conf.d/galera.cnf配置为：

[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="test_cluster"
wsrep_cluster_address="gcomm://this_node_ip,second_ip,third_ip"

# Galera Synchronization Configuration
wsrep_sst_method=rsync

# Galera Node Configuration
wsrep_node_address="this_node_ip"
wsrep_node_name="this_node_name"

对其他2个节点（使用它自己的IP地址）重复上述步骤。并为每个节点使用以下命令sudo service mysql stop停止mysql。

在第一个节点中，我尝试使用以下命令开始：

sudo service mysql start --wsrep-new-cluster

但它返回：Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.

在systemctl status mysql.service中，它说：

● mysql.service - LSB: start and stop MySQL

Feb 09 15:53:16 systemd[1]: mysql.service: Unit entered failed state.

希望这些信息有所帮助。
