mysql数据库的安装配置

mysql二进制包的安装过程

 

#解压二进制包到/usr/local

[root@station58 ~]# tar -vxf mysql-5.5.19-linux2.6-i686.tar.gz -C /usr/local

#为解压的包创建软链接

[root@station58 ~]# cd /usr/local
[root@station58 local]# ln -sv mysql-5.5.19-linux2.6-i686 mysql

 

#创建mysql组和用户

[root@station58 local]# groupadd mysql
[root@station58 local]# useradd -g mysql -s /sbin/nologin -M mysql
[root@station58 local]# id mysql

 

#更改mysql目录的属主和属组

[root@station58 local]# cd mysql
[root@station58 mysql]# chown -R mysql:mysql ./
[root@station58 mysql]# ll

 

#创建磁盘分区
[root@station58 mysql]# fdisk /dev/sdb

#查看磁盘分区情况
Command (m for help): p

#创建新分区大小为10G

Command (m for help): n
First cylinder (3652-15665, default 3652):
Using default value 3652
Last cylinder or +size or +sizeM or +sizeK (3652-15665, default 15665): +10G

#转换分区的格式

Command (m for help): t
Partition number (1-5): 5
Hex code (type L to list codes): 8e
Changed system type of partition 5 to 8e (Linux LVM)

#保存并退出

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

#系统内核重读磁盘分区信息

[root@station58 mysql]# partprobe /dev/sdb

 

#创建物理卷

[root@station58 mysql]# pvcreate /dev/sdb5
  Physical volume "/dev/sdb5" successfully created           #此行表示物理卷创建成功

#创建逻辑卷组

[root@station58 mysql]# vgcreate myvg /dev/sdb5 

/dev/cdrom: open failed: Read-only file system
  Attempt to close device '/dev/cdrom' which is not open.
  Volume group "myvg" successfully created                         #此行表示逻辑卷组创建成功

[root@station58 mysql]# lvcreate -L 3G -n mydata myvg
  Logical volume "mydata" created

[root@station58 mysql]# lvs
