innodb的innodb_buffer_pool_size 在32机器上只能最大为2G，这样本来增加内存为了提高速度，受这个限制发挥不出来。听说想到64位的环境可以用超过2G的内存，于是就开始重新部署。
环境：
Mysql 5.1.33
安装
Centos安装没有什么特别，只是要记得下载64的系统,
MYSQL编译安装，对于安装过的人，也是很简单，这里还是把某些过程写一下，以供参考。
安装完Centos后，就按以下步骤操作：
1.换CentOS的yum源
cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.bak
wget http://blog.s135.com/soft/linux/centos/5.2/CentOS-Base.repo
2.定时校正服务器时钟
yum install ntp #如果ntp已经安装可以略过
crontab -e
加入如下一行：
15 3 * * * /usr/sbin/ntpdate 210.72.145.44 > /dev/null 2>&1
3.安装所需的程序
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel
4.下载软件
mkdir -p /opt/software
wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.33.tar.gz/from/http://mysql.he.net/
wget http://www.sphinxsearch.com/downloads/sphinx-0.9.9-rc1.tar.gz
5.编译安装软件
5.2编译安装mysql
以下内容存为mysql-install.sh
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.33.tar.gz
#sphinx安装
cd /opt/software
tar zxvf sphinx-0.9.9-rc1.tar.gz -C /opt
cd /opt/sphinx-0.9.9-rc1
cp -R /opt/sphinx-0.9.9-rc1/mysqlse /opt/mysql-5.1.33/storage/sphinx
cd /opt/mysql-5.1.33
sh BUILD/autorun.sh
cd mysql-5.1.33/
./configure --prefix=/usr/local/webserver/mysql/ --without-debug --without-bench --enable-thread-safe-client --enable-assembler --enable-profiling --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --with-charset=latin1 --with-extra-charsets=utf8 --with-plugins=innobase --with-mysqld-user=mysql --without-embedded-server --with-server-suffix=-yicike --enable-local-infile --with-plugins=sphinx --with-plugins=all --with-unix-socket-path=/usr/local/webserver/mysql/sock/mysql.sock
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ../
执行(如果不是另存为mysql-install.sh的可以忽略这一步)
chmod +x mysql-install.sh
./mysql-install.sh
5.2.1创建MySQL数据库存放目录 www.britepic.org
mkdir -p /data/mysql/data/
chown -R mysql:mysql /data/mysql/
5.2.2以mysql用户帐号的身份建立数据表
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data/mysql/data --user=mysql
可能会失败，如果机器里以前安装了mysql，需要将原来的my.cnf名称修改为my.cnf.temp
5.2.3创建my.cnf配置文件
vim /data/mysql/my.cnf
输入以下内容
[client]
default-character-set = utf8
port = 3306
socket = /tmp/mysql.sock
[mysql]
prompt="(\u:www.yicike.com:)[\d]> "
