安装环境   centos x86_64

最小化安装

安装  “development tools"  "server platform development"

"desktop platform development" 组件

二进制包安装

一  准备数据存放的文件系统

新建逻辑卷  挂载到 /mydata ,然后新建目录   /my

data/data作为数据库存放目录

1 安装LVM

[root@www ~]# rpm -ql lvm
[root@www ~]# yum install lvm2

2 新增一块硬盘，划分分区，查看磁盘分区

[root@www ~]# fdisk -l /dev/sdb
Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x47e9e58bDevice Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1306    10490413+  83  Linux
/dev/sdb2            1307        2610    10474380    5  Extended
/dev/sdb5            1307        2610    10474348+  83  Linux

3 创建逻辑分区

修改分区ID 号

fdisk /dev/sdb
WARNING: DOS-compatible mode is deprecated. It's strongly recommended toswitch off the mode (command 'c') and change display units tosectors (command 'u').
Command (m for help): p

[root@www ~]# pvcreate /dev/sdb1Physical volume "/dev/sdb1" successfully created[root@www ~]# pvcreate /dev/sdb5Physical volume "/dev/sdb5" successfully created

[root@www ~]# vgcreate myvg /dev/sdb1 /dev/sdb5Volume group "myvg" successfully created[root@www ~]# lvcreate -n mydata -L 10G myvgLogical volume "mydata" created [root@www ~]# mke2fs -t ext4 /dev/myvg/mydata
[root@www ~# mkdir mydata
[root@www ~]# mount /dev/myvg/mydata /mydata/
[root@www ~]# vim /etc/fstab
/dev/myvg/mydata/mydata ext4 defaults 0 0
[root@www ~]# mount -a
[root@www ~]# mount

4 在/mydata下创建子目录，作为mysql数据库目录

[root@www ~]# mkdir /mydata/data/

二 创建mysql 用户 修改权限

[root@www ~]# useradd mysql

[root@www ~]# chown -R mysql:mysql /mydata/data/

三 安装mysql

1 解压缩到/usr/local/  更改权限

[root@www ~]# tar xf mysql-5.5.37-linux2.6-x86_64.tar.gz -C /usr/local/

[root@www local]# ln -sv mysql-5.5.37-linux2.6-x86_64  mysql

[root@www local]# chown -R mysql:mysql mysql

2 配置my.cnf

[root@www mysql]# cd support-files/
[root@www support-files]# cp my-large.cnf /etc/my.cnf
[root@www mysql]# vim /etc/my.cnf
添加datadir=/mydata/data thread_cache_size=4 (物理核心的一到二倍）

3 服务脚本

[root@www support-files]# cp mysql.server /etc/rc.d/init.d/mysqld
[root@www mysql]# chkconfig mysqld on

4 初始化脚本

[root@www mysql]#scripts/mysql_install_db --user=mysql --datadir=/mydata/data/  Installing MySQL system tables....
/bin/mysqld
: error whileloading shared libraries
[root@www mysql]# yum install libaio

[root@www mysql]# ls /mydata/data/

5 修改PATH变量

[root@www mysql]# vim /etc/profile.d/mysql.sh
添加exportPATH=/usr/local/mysql/bin:$PATH
[root@www mysql]# source /etc/profile.d/mysql.sh

6 输出mysql头文件至系统头文件路径

[root@www mysql]# ln -sv /usr/local/mysql/include/ /usr/include/mysql

7 输出mysql库文件至系统库文件查找路径

[root@www mysql]# vim /etc/ld.so.conf.d/mysql.conf
添加/usr/local/mysql/lib
[root@www mysql]# ldconfig -v

8 输出mysql man 手册至man命令查找路径

[root@www mysql# vim /etc/man.config
添加MANPATH/usr/local/mysql/man

9测试连接

[root@www ~]# mysql
