安装MariaDB 10.1

yum install MariaDB-server MariaDB-client -y

 

初始化数据库:

/usr/bin/mysql_install_db --datadir=/data/mysql --user=mysql

 

配置参数:

vim /etc/my.cnf.d/server.cnf

[mysqld]

server-id = 1

datadir = /data/mysql

log_error = /data/mysql/err.log

log_bin = mysql-bin

wsrep_sst_method=rsync

wsrep_sst_auth="sst:86rt6y1qaz@WSX"

# Allow server to accept connections on all interfaces.

bind-address=0.0.0.0

启动第一个数据库:192.168.0.241

/etc/init.d/mysql start --wsrep-new-cluster

注:在集群中启动第一台数据库时,必须加上参数--wsrep-new-cluster

 

依次启动多台数据库:192.168.0.242 192.168.0.243

/etc/init.d/mysql start --wsrep_cluster_address=gcomm://192.168.0.241

注:依次启动多台数据库时,需要加上参数--wsrep_cluster_address并指定IP地址,以加入集群

 

当集群中的所有数据库全部关闭后第一台启动的数据库:

需要添加 --wsrep-new-cluster选择

 

当集群中只要有一台数据库未关闭,其它集群节点启动不需要添加任何额外的参数

 

注:关闭数据库一定要正常关闭,否则数据库可能会无法启动

 

 

查看集群状态:

mysql>show status like wsrep%;

 

初次启动碰到的故障:

 

 [ERROR] InnoDB: auto-extending data file ./ibdata1 is of a different size 640 pages (rounded down to MB) than specified in the .cnf file: initial 768 pages, max 0 (relevant if non-zero) pages!

问题原因:

在初始化数据库时系统自动建立了ibdata1,ib_logfile0,ib_logfile1几个文件

在配置文件中由于配置了:innodb_data_file_path = ibdata1:10M;ibdata2:10M:autoextend,跟初始化时的ibdata1的大小不一致导致的

默认的ibdata1大小为8M,而我在此配置的为10M,是导致问题的原因

解决办法:

mysqldata目录下,删除ibdata1,ib_logfile0,ib_logfile1

在重新启动mysql,系统会根据配置再次生成ibdata文件
