LINUX下安装MYSQL

升级系统先

yum -y install gcc gcc-c++ ncurses ncurses-devel

下载MYSQL

wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.46.tar.gz/from/http://mysql.cdpa.nsysu.edu.tw/

创建用户和组

groupadd mysql
useradd -g mysql mysql

编译安装

./configure --prefix=/usr/local/mysql --without-debug --with-charset=utf8 --with-extra-charsets=gbk,gb2312,utf8 --with-unix-socket-path=/tmp/mysql.sock --with-plugins=partition,innobase,myisammrg --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-big-tables --with-read-line --with-ssl --with-embedded-server --with-pthread --enable-thread-safe-client --enable-local-infile --enable-assembler

make

make install


创建数据库存储目录

mkdir -p /data0/mysql/3306/data
mkdir -p /data0/mysql/3306/binlog
mkdir -p /data0/mysql/3306/relaylog
chown -R mysql:mysql /data0/mysql/

初始化MYSQL表

/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data0/mysql/3306/data --user=mysql

创建MYSQL配置文件

vi /data0/mysql/3306/my.cnf

fi

修改执行权限

chmod +x /data0/mysql/3306/mysql

启动服务

/data0/mysql/3306/mysql start

登陆到MYSQL创建一个用户

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