编译安装MySQL-5.5.28通用二进制

[iyunv@localhost local]# groupadd -r -g 306 mysql  为mysql创建一个系统用户

[iyunv@localhost local]# useradd -r -g 306 -u 306 mysql

[iyunv@localhost local]# tar -xf mysql-5.5.28-linux2.6-x86_64.tar.gz

[iyunv@localhost local]# ln -sv  mysql-5.5.28-linux2.6-x86_64 mysql

[iyunv@localhost local]# chown -R mysql.mysql mysql/*

[iyunv@localhost local]# chmod -R 750 mysql/*

[iyunv@localhost mysql]# less INSTALL-BINARY  查看安装说明

[iyunv@localhost mysql]# ls scripts/

mysql_install_db  初始化系统的脚本

[iyunv@localhost mysql]# scripts/mysql_install_db  --help 查看说明

--datadir=path 改变data目录的位置，建议放到一个逻辑卷上

--user=user_name  以哪个用户进行初始化

创建一个逻辑卷

fdisk /dev/sda

n

4

n

e

+20G

t

5

8e

p

w

partprobe /dev/sda

pvcreate /dev/sda5 创建物理卷

vgcreate myvg /dev/sda5 把sda5创建成卷组叫myvg

lvcreate -n mydata -L 5G myvg 指定逻辑卷大小和逻辑卷名

lvs 查看逻辑卷

mke2fs -j /dev/myvg/mydata 格式化

[iyunv@localhost mysql]# mkdir -p /mydata/data

[iyunv@localhost mysql]# vim /etc/fstab 开机自动挂载

/dev/myvg/mydata        /mydata                 ext3    defaults        0 0

[iyunv@localhost mysql]# chown -R mysql.mysql /mydata/data

[iyunv@localhost mysql]# chmod o-rx /mydata/data

[iyunv@localhost mysql]# scripts/mysql_install_db   --user=mysql   --datadir=/mydata/data/

[iyunv@mylinux mysql]# chown -R root /usr/local/mysql/*

/mydata/data   必须是mysql:mysql

[iyunv@mylinux mysql]# cp support-files/mysql.server  /etc/init.d/mysqld  把mysql脚本放到init.d下

[iyunv@mylinux mysql]# ls -l /etc/init.d/mysqld 查看是否有执行权限

[iyunv@mylinux mysql]# chkconfig  --add  mysqld

[iyunv@mylinux mysql]# chkconfig  --list mysqld

此时还不能启动，没有配置文件

/etc/my.cnf  -->  /etc/mysql/my.cnf  -->  $BASEDIR/my.cnf  -->$DATADIR/my.cnf  --> ~/.my.cnf

以最后一个为准

[iyunv@mylinux support-files]# head my-huge.cnf

# This is for a large system with memory of 1G-2G where the system runs mainly

根据内存大小选择合适的配置文件

[iyunv@mylinux support-files]# cp my-large.cnf  /etc/my.cnf

thread_concurrency = 2    此项填写CPU个数*2

[iyunv@mylinux support-files]# cat /proc/cpuinfo 查看cpu个数

加一项 datadir=/mydata/data

service mysqld start

netstat -tnlp

[iyunv@mylinux support-files]# vim /etc/profile.d/mysql.sh

export PATH=$PATH:/usr/local/mysql/bin

MySQL服务器维护了两类变量：

服务器变量：

定义MySQL服务器运行特性

show global variables [like 'STRING’]；

状态变量：

show global status [like 'STRING’]；

MySQL 通配符

_任意单个字符

%任意长度的任意字符

[iyunv@localhost ~]# vim /etc/man.config

MANPATH /usr/man

MANPATH /usr/share/man

MANPATH /usr/local/man

MANPATH /usr/local/share/man

MANPATH /usr/X11R6/man

MANPATH /usr/local/mysql/man 新增一条

[iyunv@localhost ~]# vim /etc/ld.so.conf.d/mysql.conf

/usr/local/mysql/lib

[iyunv@localhost ~]# ldconfig -v 让系统重新读取

[iyunv@localhost ~]# ls -l /etc/ld.so.cache 缓存到这个文件

-rw-r--r--. 1 root root 41662 Jul 27 17:15 /etc/ld.so.cache

[iyunv@localhost mysql]# ln -sv /usr/local/mysql/include  /usr/include/mysql
