编译安装MySQL

一、环境介绍

操作系统：Redhat5.8_64bit
MySQL版本:mysql-5.5.28.tar.gz
所需要的软件：
cmake-2.8.8.tar.gz
mysql-5.5.28.tar.gz
二、安装前环境准备

#yum grouplist  //检查开发环境是否安装了
没有执行下面命令安装：
#yum groupinstall "Development Libraries" -y
#yum groupinstall "Development Tools" -y

三、安装cmake

# tar xf cmake-2.8.8.tar.gz
# cd cmake-2.8.8
# ./configure
# make
# make install

四、为MySQL准备数据存放目录

# fdisk /dev/sdb   （特意为mysql准备一块磁盘）
Command (m for help): n
Command action
e   extended
p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-2610, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-2610, default 2610): +20G  //设置分区大小
Command (m for help): t  //修改分区类型
Selected partition 1
Hex code (type L to list codes): 8e  //类型为8e
Changed system type of partition 1 to 8e (Linux LVM)
Command (m for help): p
Disk /dev/sdb: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        2610    20964793+  8e  Linux LVM
Command (m for help): w    //保存
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
#partprobe /dev/sdb1  //同步分区信息
#pvcreate /dev/sdb1   //创建PV
Writing physical volume data to disk "/dev/sdb1"

#vgcreate myvg /dev/sdb1   //创建VG

#lvcreate -L 10G -n mydata myvg   //创建LV

#lvs

mydata myvg -wi-a- 10.00G
#mke2fs -j /dev/myvg/mydata   //格式化文件系统
#mkdir /mydata   //创建LV的挂载目录
#vim /etc/fstab   //设置开机自动挂载
/dev/myvg/mydata  /mydata ext3 defaults 0 0   -->添加这行内容就可以
#mount -a    //加载/etc/fstab文件
#mkdir /mydata/data   //创建MySQL数据文件存放的目录

五、创建用户和组

#groupadd -r mysql
#useradd -r -g mysql -s /sbin/nologin mysql
#chown -R mysql.mysql /mydata/data

六、安装mysql
1、解压安装MySQL

#tar xf mysql-5.5.28.tar.gz
#cd mysql-5.5.28
#cmake . -LH
#cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/mydata/data \
-DSYSCONFDIR=/etc \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_ZLIB=system \
-DWITH_LIBWRAP=0 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci
#make
#make install

2、初始化mysql

# cd /usr/local/mysql/
# chown -R :mysql .   //修改属组为mysql
# scripts/mysql_install_db --user=mysql --datadir=/mydata/data

3、修改配置文件

# cd /usr/local/mysql/
# cp support-files/my-large.cnf /etc/my.cnf
# cp support-files/mysql.server /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --list mysqld
mysqld  0:off 1:off 2:on  3:on  4:on  5:on  6:off

4、启动MySQL服务

# service mysqld start

5、配置mysql登录密码

# /usr/local/mysql/bin/mysqladmin -u root password '123456'
# /usr/local/mysql/bin/mysql -uroot -p

6、添加Mysql环境变量

# cd /etc/profile.d/
# vim mysql.sh   //添加如下一行内容：
export PATH=$PATH:/usr/local/mysql/bin
# chmod +x mysql.sh
# . /etc/profile.d/mysql.sh

以上完成编译安装MySQL！！！
