这篇文章主要介绍了centos 6.5下安装安装 5.6教程,非常不错，具有参考借鉴价值，需要的朋友可以参考下
1.下载安装对应的RPM包
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进入安装设置密码
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]<p>13.授予用户权限</p><pre class="brush:sql;">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';
