  • Mariadb Galera Cluster 搭建集群

    1.安装MariaDB 和Galera

    见另外一篇博客

    2.环境修改

      2.1 防火墙和SELinux

      这里不做说明,参照网上教程,和官方的配置

      2.2. 创建用于节点同步的账号

    [root@localhost ~]# mysql -uroot -p
    MariaDB [(none)]> grant usage on *.* to sst@'%' identified by 'ssTT-488';
    MariaDB [(none)]> flush privileges;

      2.3. 修改mysql默认字符集

    MariaDB [(none)]> show variables like 'character%';
    MariaDB [(none)]> set character_set_server = utf8;
    MariaDB [(none)]> set character_set_database = utf8;

     

    3.配置相关的参数

    http://galeracluster.com/documentation-webpages/training/tutorials/wsrep-configuration.html

    https://mariadb.com/kb/en/library/configuring-mariadb-galera-cluster/

      注意:

         1.启动第一个节点用的是命令:galera_new_cluster

         2.遇到错误查看日志:journalctl -xe

         3.参照的一篇博客:https://www.cnblogs.com/liujiduo/p/5066803.html

         4.没有很多东西了,配置文件  /etc/my.cnf 很重要

    4.相关命令实例   文件位置  /etc/my.cnf

     [mysqld]
    binlog_format = ROW
    #bind-address = 192.168.126.129
    default_storage_engine = innodb
    innodb_autoinc_lock_mode = 2
    innodb_flush_log_at_trx_commit = 0
    innodb_buffer_pool_size = 122M
    wsrep_provider=/usr/lib64/galera/libgalera_smm.so
    wsrep_provider_options ="gcache.size = 300M; gcache.page_size = 300M"
    wsrep_cluster_name ="MyCluster"
    wsrep_cluster_address="gcomm://192.168.126.129"
    wsrep_sst_method = rsync
    wsrep_node_name = Node11
    wsrep_node_address ="192.168.126.129"
    wsrep_sst_auth=sst:ssTT-488  
    wsrep_on=ON

      注意:1.wsrep_provider 路径以系统中实际文件路径为准

         2.wsrep_cluster_address 后面的参数没有空格,实例中有的是有空格的,把空格去掉

    5.检查是否启动成功

     命令:mysql -u root -p    登录MariaDB 数据库
