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 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]> "

no-auto-rehash

#slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 8G #由于我的机器是16G

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

[mysqldump]

quick

max_allowed_packet = 32M
5.2.4创建管理MySQL数据库的shell脚本
vim /data/mysql/mysql

输入以下内容

#!/bin/sh

mysql_username="admin"

mysql_password="12345678"

function_start_mysql()

{

printf "Starting MySQL...\n"

[align=center] [/align]

/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data/mysql/my.cnf 2>&1 > /dev/null &

}

function_stop_mysql()

{

printf "Stoping MySQL...\n"

/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown

}

function_restart_mysql()

{

printf "Restarting MySQL...\n"

function_stop_mysql

sleep 5

function_start_mysql

}

function_kill_mysql()

{

kill -9 $(ps -ef | grep 'bin/mysqld_safe' | awk '{printf $2}')

kill -9 $(ps -ef | grep 'libexec/mysqld' | awk '{printf $2}')

}

if [ "$1" = "start" ]; then

function_start_mysql

elif [ "$1" = "stop" ]; then

function_stop_mysql

elif [ "$1" = "restart" ]; then

function_restart_mysql

elif [ "$1" = "kill" ]; then

function_kill_mysql

else

printf "Usage: /data/mysql/mysql {start|stop|restart|kill}\n"

fi

加上可执行权限

chmod +x /data/mysql/mysql

5.2.5创建一个具有root权限的用户（admin）和密码（12345678）

启动数据库

/data/mysql/mysql start

通过命令行登录管理MySQL服务器(不用密码)

/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

创建账号

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';

FLUSH PRIVILEGES;

停止数据库

/data/mysql/mysql stop

phpmyadmin管理

可能phpmyadmin连接不上mysql，这是由于原来安装了MYSQL，需要修改php.ini，加上以下这个

mysql.default_socket =/tmp/mysql.sock

部署成功后，我们价网的速度明显快多了。
