Linux系统上安装MySQL 5.6

安装环境 :

软件版本位数MySQL5.6.2232CentOS6.432VMware9.0.132

Mysql官方下载地址，可以根据当前系统自动识别适合当前系统版本的mysql版本：

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

官网比较慢，百度云盘包含32位和64位的：

一，卸载自带mysql，删除MySQL的lib库，服务文件

[root@localhost  ~]# yum remove mysql mysql-server mysql-libs

如果之前安装过，则执行rpm -ev进行删除，删除失败，则是有依赖项，则先删除依赖项

[root@localhost  ~]# rpm -ev MySQL-server-5.0.22-0.i386
[root@localhost  ~]# rpm -ev MySQL-client-5.0.22-0.i386

清除所有mysql相关文件：

[root@localhost  ~]#find / -name mysql
[root@localhost  ~]#rm -rf 文件或者文件夹

查看是否有残留文件：

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

执行命令卸载MySQL相关的文件

[root@localhost  ~]# yum -y remove MySQL*

二，安装MySQL

1.复制mysql安装包到安装目录

[root@localhost opt]# mkdir mysql[root@localhost opt]# cp /home/duke147/Desktop/Tools/MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tar /opt/mysql/[root@localhost opt]# cd mysql/[root@localhost mysql]# ls -a .  ..  MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tar

2.解压安装包

[root@localhost mysql]# tar xvf MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tarMySQL-test-5.6.22-1.linux_glibc2.5.i386.rpm                   #MySQL的测试组件MySQL-shared-5.6.22-1.linux_glibc2.5.i386.rpm                 #MySQL的共享库MySQL-shared-compat-5.6.22-1.linux_glibc2.5.i386.rpm          #MySQL版本兼容的包MySQL-client-5.6.22-1.linux_glibc2.5.i386.rpm                 #MySQL客户端程序MySQL-devel-5.6.22-1.linux_glibc2.5.i386.rpm                  #MySQL的库和头文件MySQL-embedded-5.6.22-1.linux_glibc2.5.i386.rpm               #MySQL的嵌入式程序MySQL-server-5.6.22-1.linux_glibc2.5.i386.rpm                 #MySQL服务端程序

3.安装服务端

4.查看，安装客户端，库文件

[root@localhost mysql]# rpm -qa | grep -i mysqlMySQL-server-5.6.22-1.linux_glibc2.5.i386[root@localhost mysql]# rpm -ivh MySQL-client-5.6.22-1.linux_glibc2.5.i386.rpmPreparing...                ########################################### [100%]   1:MySQL-client           ########################################### [100%][root@localhost mysql]# rpm -ivh MySQL-devel-5.6.22-1.linux_glibc2.5.i386.rpm Preparing...                ########################################### [100%]   1:MySQL-devel            ########################################### [100%]

MySQL默认安装路径：

a.数据库目录： /var/lib/mysql/
b.配置文件：     /usr/share/mysql
c.相关命令：     /usr/bin
d.启动脚本：     /etc/rc.d/init.d/

5.修改配置文件，将MySQL的配置文件拷贝到/etc目录下。

[root@localhost mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

#如果使用默认配置，则不需要进行修改

[root@localhost mysql]# vi /etc/my.cnf

6.初始化MySQL

[root@localhost mysql]# /usr/bin/mysql_install_db

7.启动MySQL

[root@localhost mysql]# service mysql startStarting MySQL.... SUCCESS! 

检测mysql 3306是否安打开

[root@localhost mysql]# netstat -nattcp        0      0 :::3306                     :::*                        LISTEN  

8.查看root账号初始信息

[root@localhost mysql]# cat /root/.mysql_secret# The random password set for the root user at Thu Dec 18 21:08:44 2014 (local time): vuN8xfuKTRnmqX3I

9.使用默认密码登陆mysql

[root@localhost mysql]# mysql -u root -pvuN8xfuKTRnmqX3IWarning: Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 4Server version: 5.6.22Copyright (c) 2000, 2014, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> 

修改默认密码：

mysql> set password = password('123456');Query OK, 0 rows affected (0.02 sec)

退出mysql

mysql> quit;Bye

10.添加自启动服务

[root@localhost ~]# chkconfig --add mysql[root@localhost ~]# chkconfig mysql on

11.配置远程访问

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;Query OK, 0 rows affected (0.01 sec)

刷新权限

mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

配置单个IP访问权限，*.* 指 【数据库.表】：

mysql > GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.56' IDENTIFIED BY '123456' WITH GRANT OPTION;flush privileges;

关闭防火墙

[root@localhost ~]# service iptables stopiptables: Flushing firewall rules:                         [  OK  ]iptables: Setting chains to policy ACCEPT: filter          [  OK  ]iptables: Unloading modules:                               [  OK  ][root@localhost ~]# service iptables statusiptables: Firewall is not running.

修改密码

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

查看数据库

mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || performance_schema || test               |+--------------------+4 rows in set (0.00 sec)
