MariaDB集群安装部署v1.0.doc

MariaDB集群安装部署v1.0 MariaDB集群 一、 准备 利用keepalived构建高可用MySQL-HA，保证两台MySQL数据的一致性，然后用keepalived实现虚拟VIP，通过keepalived自带的服务监控功能来实现MySQL故障时自动切换。 硬件拓扑如下： VIP：192.168.1.200 mysql2:192.168.1.202 二、 安装maridDB： #MariaDB简化安装 I. 建立用户、组及文件夹 [root@localhost ~]# groupadd mysql [root@localhost ~]# useradd -g mysql mysql [root@localhost ~]#mkdir /server [root@localhost ~]#chmod 755 /server II. 拷贝上传MariaDB安装文件到/server文件夹 [root@localhost ~]# cd /server [root@localhost server]# tar -zxvf mariadb-5.5.31-linux-x86_64.tar.gz III. 建立快捷链接 [root@localhost server]# ln -s /server/ mariadb-5.5.31-linux-x86_64 /usr/local/mysql [root@localhost server]# cd /usr/local/mysql [root@localhost mysql]# chown -R /usr/local/mysql . [root@localhost mysql]# chgrp -R /usr/local/mysql . [root@localhost mysql]# scripts/mysql_install_db --user=mysql [root@localhost mysql]# chown -R root . [root@localhost mysql]# chown -R mysql data [root@localhost mysql]# bin/mysqld_safe --user=mysql amp; IV. 拷贝服务到/etc/init.d，配置文件到/etc下 [root@localhost mysql]#cp support-files/mysql.server /etc/init.d/mysql #/etc/init.d/mysql后的mysql是服务名，可自定义 [root@localhost mysql]#cp support-files/my-medium.cnf /etc/my.cnf V. 修改环境变量，设置开机启动 [root@localhost mysql]#vi /etc/profile export PATH=/usr/local/mysql/bin:$PATH #ESC退出编辑，:wq保存 [root@localhost mysql]#source /etc/profile VI. 服务自启动 [root@localhost mysql]#chkconfig mysql on [root@localhost mysql]#service mysql start VII. 测试 [root@localhost mysql]#mysql MariaDB [(none)]gt; use mysql MariaDB [mysql]gt; select user,host,password from user; VIII. 删除不安全用户 MariaDB [mysql]gt; drop user #39;#39;@#39;localhost#39;; Query OK, 0 rows affected (0.05 sec) MariaDB [mysql]gt; drop user #39;root#39;@#39;::1#39;; Query OK, 0 rows affected (0.00 sec) MariaDB [mysql]gt; drop user #39;root#39;@#39;127.0.0.1#39;; Query OK, 0 rows affected (
