Centos 6.5下安装MySQL 5.6教程

1.下载linux对应的rpm包

wget http://cdn.mysql.com//downloads/mysql-5.6/mysql-5.6.33-1.el6.x86_64.rpm-bundle.tar

2.解压tar包

tar -xvf mysql-5.6.33-1.el6.x86_64.rpm-bundle.tar

3.安装mysql

rpm -ivh mysql-server-5.6.33-1.el6.x86_64.rpm 
rpm -ivh mysql-client-5.6.33-1.el6.x86_64.rpm 
rpm -ivh mysql-devel-5.6.33-1.el6.x86_64.rpm

如果出现:

error: failed dependencies:
    libaio.so.1()(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64
    libaio.so.1(libaio_0.1)(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64
    libaio.so.1(libaio_0.4)(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64

下载libaio

yum install libaio

如果出现:

error: failed dependencies:
    libnuma.so.1()(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64
    libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64
    libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-server-5.6.33-1.el6.x86_64

下载numactl

yum install numactl

4.初始化mysql及设置密码

/usr/bin/mysql_install_db
service mysql start

如果启动失败可能是数据块所在目录没有权限

cat /root/.mysql_secret #查看root账号密码
mysql> set password = password('123456');
mysql> exit

如果.mysql_secret文件不存在,先停止mysql进入安全模式设置密码

service mysql stop
mysqld_safe --skip-grant-tables&
mysql -u root mysql
mysql> update user set password=password("new password") where user='root';
mysql> flush privileges;

5.允许远程登陆

mysql> use mysql;
mysql> select host,user,password from user;
mysql> update user set host='%' where user='root' and host='localhost';
mysql> flush privileges;
mysql> exit

6.设置开机自启动

chkconfig mysql on
chkconfig --list | grep mysql
mysql      0:off  1:off  2:on  3:on  4:on  5:on  6:off

7.mysql的默认安装位置

/var/lib/mysql/        #数据库目录
/usr/share/mysql       #配置文件目录
/usr/bin           #相关命令目录
/etc/init.d/mysql       #启动脚本

8.常用命令

1.使用客户端工具连接到数据库

mysql -u root -p

2.查看mysql服务器中包含那些数据库

mysql>show databases;

3.查看数据库中的数据表信息

mysql>show tables;

4.切换数据库

mysql>use mysql;

5.创建新的数据库

mysql>create database 数据库名字;

6.创建新的数据表

mysql>create table 表名 (字段定义)

7.删除一个数据表

mysql>drop table 数据库名.表名;

8.删除一个数据库

mysql>drop database 数据库名

9.备份整个数据库

mysqldump -u root -p auth > mysql-auth.sql

10.备份数据库mysql中的user表

mysqldump -u root -p mysql user > mysql.host-user.sql

11.备份mysql服务器中所有数据库

mysqldump -u root -p -all-databases > mysql-all.sql

12.恢复数据库

mysql -u root -p [数据库名]< mysql-all.sql

13.授予用户权限

grant 权限列表 on 数据库名.表名 to 用户名@来源地址 [identified by '密码']
grant select on mysql.user to daxiong@'localhost' identified by'123456';
