Centos 6.5下安装MySQL 5.6教程

1.下载Linux对应的RPM包

http://dev.mysql.com/downloads/mysql/5.6.html

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_dbservice 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 stopmysqld_safe --skip-grant-tables&mysql -u root mysqlmysql> 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 onchkconfig --list | grep mysqlmysql 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
