Linux下64位MySQL安装部署过程

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：

CentOS 5.3 64位

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
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 ://mysql.he.net/
wget
 
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

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
