Linux下MySQL-5.6.26 RPM包安装

1.前言

       

本文测试环境：

CentOS release 6.4（Linux version 2.6.32-358.el6.x86_64）

MySQL-5.6.26 RPM包下载地址：http://dev.mysql.com/downloads/mysql/，相关的文档参详：http://dev.mysql.com/doc/refman/5.7/en/linux-installation-rpm.html。
MySQL社区版对应的RPM包如下：

Package Name	Summary
mysql-community-server	Database server and related tools
mysql-community-client	MySQL client applications and tools
mysql-community-common	Common files for server and client libraries
mysql-community-devel	Development header files and libraries for MySQL database client applications

mysql-community-libs-compat	Shared compatibility libraries for previous MySQL installations
mysql-community-embedded	MySQL embedded library
mysql-community-embedded-devel	Development header files and libraries for MySQL as an embeddable library
mysql-community-test	Test suite for the MySQL server

2.安装前准备

1）检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm–e名称）

[root@nn ~]# rpm -qa | grep -i mysql

[root@nn ~]# yum -y remove mysql-libs*

2）下载Linux对应的RPM包，如：CentOS6.4_64对应的RPM包，本文已在官网下载，这里就不详叙了。

3）MySQL默认安装路径

Directory	Contents of Directory
/usr/bin	Client programs and scripts
/usr/sbin	The mysqld server
/var/lib/mysql	Log files, databases
/usr/share/info	Manual in Info format
/usr/share/man	Unix manual pages
/usr/include/mysql	Include (header) files
/usr/lib/mysql	Libraries
/usr/share/mysql	Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation
/usr/share/sql-bench	Benchmarks

3.安装MySQL

[root@nn ~]# cd /home/MySql/MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle/

[root@nn MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle]# rpm -ivh MySQL-server-5.6.26-1.linux_glibc2.5.x86_64.rpm

[root@nn MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle]# rpm -ivh MySQL-client-5.6.26-1.linux_glibc2.5.x86_64.rpm

4.初始化MySQL及密码

[root@nn ~]# service mysql start

[root@nn ~]# more /root/.mysql_secret

[root@nn ~]# mysql -u root -p

mysql> set PASSWORD=PASSWORD('123456');

5.允许远程登陆

mysql> use mysql;

mysql> select host,user,password from user;

mysql> update user set password=password('123456') where user='root';

mysql> update user set host='%' where user='root' and host='localhost';

mysql> flush privileges;

6. 修改字符集和数据存储路径

配置/etc/my.cnf文件，修改数据存放路径、mysql.sock路径以及默认编码utf-8。

[root@nn ~]# cp /usr/my.cnf /etc/my.cnf

7.设置开机自启动

[root@nn ~]# chkconfig mysql on

[root@nn ~]# chkconfig --list | grep mysql

8.允许远程登录

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT option;

         该SQL的作用是将所有的用户名，都设置能远程访问该mysql中所有的表，如果不想都放开，可以根据这个规则，来设置.grant权限1，权限2，…权限n
on数据库名.表名to用户名@用户地址identified
by‘口令’。
