基本环境配置
修改hosts文件
#cat /etc/hosts
# controller
10.0.0.11 controller # virtual IP
10.0.0.12 controller1
10.0.0.13 controller2
10.0.0.14 controller3
memcache相关配置,例如keystone配置
Memcached_servers=controller1:11211,controller2:11211,controller3:11211
配置共享服务
数据库配置
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
binlog_format=ROW
bind-address=10.0.0.12
# InnoDB Configuration
default_storage_engine=innodb
innodb_autoinc_lock_mode=2
innodb_flush_log_at_trx_commit=0
innodb_buffer_pool_size=122M
# Galera Cluster Configuration
wsrep_provider=/usr/lib/libgalera_smm.so
wsrep_provider_options="pc.recovery=TRUE;gcache.size=300M"
wsrep_cluster_name="my_example_cluster"
wsrep_cluster_address="gcomm://GALERA1-IP,GALERA2-IP,GALERA3-IP"
wsrep_sst_method=rsync
可能需要添加
wsrep_node_address="192.168.1.1"
wsrep_node_name="Galera1"
