MariaDB是基于二机制包安装的,不需要编译
一、数据磁盘准备
我们在虚拟机上另外挂一块磁盘,大小自己定,这里的是2G的 创建分区
查看新加的磁盘位置

我们所用的是lv逻辑卷,所以要选择类型,最要不要忘记保存分区
已创建完成 创建逻辑卷,大小2G提示空间不够,可能是计算方法不一样,就只好使用1.99G了 创建文件系统 1

修改/etc/fstab文件实现开机自动挂载 创建挂载目录
1
| [iyunv@localhost~]# mkdir /data

创建数据库目录
1
| [iyunv@localhost ~]# mkdir /data/mysql
|
创建系统用户组mysql,系统用户mysql,并更改/data/mysql/属主属组均为mysql

[iyunv@localhost local]# ls
bin etc games include lib lib64 libexec mariadb-5.5.36-linux-i686 sbin share src
[iyunv@localhost local]# ln -sv mariadb-5.5.36-linux-i686/ mysql //创建软链接
`mysql' -> `mariadb-5.5.36-linux-i686/'

配置MariaDB
1
2
| [iyunv@localhost local]# cd /usr/local/mysql
[iyunv@localhost mysql]# scripts/mysql_install_db --user=mysql--datadir=/data/mysql //运行初始化脚本,指明以用户mysql运行,数据库目录为/data/mysql
|
为MariaDB提供配置文件,并修改此文件中thread_concurrency的值为你的CPU个数乘以2,指定mysql数据库存放数据位置,比如这里使用如下行:
1
| [iyunv@localhost mysql]# cp support-files/my-large.cnf /etc/mysql.cnf
|
为mysql添加服务脚本
1
2
3
| [iyunv@localhost mysql]# cp support-files/mysql.server/etc/rc.d/init.d/mysqld
[iyunv@localhost mysql]# chmod +x /etc/rc.d/init.d/mysqld
[iyunv@localhost mysql]# chkconfig --add mysqld
|
并按照下图修改安装路径、数据路径以及配置文件路径
导出mysql环境变量
1
| [iyunv@localhost ~]# vim /etc/profile.d/mysql.sh
|
使环境变量生效
1
| [iyunv@localhost mysql]# . /etc/profile.d/mysql.sh
|
此时配置已经完成了,可以使用服务脚本启动了
启动成功
进入数据库命令行
