Redhat 6.5 安装 mysql 5.6

1. 下载需要的mysql版本

下载地址：http://dev.mysql.com/downloads/mysql/
rpm包：MySQL-client-5.6.23-1.el6.x86_64.rpm
MySQL-server-5.6.23-1.el6.x86_64.rpm
将rpm包放在自己想要放的路径，例如：/christina/mysql

2. 安装mysql-server

# cd /christina/mysql
# rpm -ivh MySQL-server-5.6.23-1.el6.x86_64.rpm
# netstat -nat

问题解决：

1）安装失败

Preparing...                ########################################### [100%]
file /usr/share/mysql/czech/errmsg.sys from install of MySQL-server-5.6.23-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.71-1.el6.x86_64

解决方法：查看系统是否装有mysql相关rpm包，如果有，则是包冲突，删除之。

# rpm -qa | grep mysql
mysql-libs-5.1.71-1.el6.x86_64
# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64

2）安装结束通过netstat -nat查看3306端口（mysql默认端口）是否被打开，如果打开，则表示服务已经启动， 安装成功，如果没有，查看mysql状态，如果是failed, 则手动启动mysql.

# /etc/rc.d/init.d/mysql status
MySQL is not running                                       [FAILED]
# /etc/rc.d/init.d/mysql start
Starting MySQL.                                            [  OK  ]
# /etc/rc.d/init.d/mysqll status
MySQL running (2126)                                       [  OK  ]

# netstat -nat

3. 安装mysql-client

# cd /christina/mysql
# rpm -ivh MySQL-client-5.6.23-1.el6.x86_64.rpm
Preparing...                ########################################### [100%]

4. 连接数据库

大费周折
总是出现这个问题：Mysql ERROR 1045 (28000): Access denied for user 'root'@'localhost'
解决方法：

# /etc/init.d/mysql stop   (service mysqld stop )
# /usr/bin/mysqld_safe --skip-grant-tables
//另外开个SSH连接
# mysql
mysql>use mysql
mysql>update user set password=password("mysql") where user="root";
mysql>flush privileges;
mysql>exit
# pkill -KILL -t pts/0 //可将pts为0的**用户(之前运行mysqld_safe的用户窗口)强制踢出

//正常启动 MySQL：</span>

# /etc/init.d/mysql start   (service mysqld start)

解决之后使用数据库又出现问题：ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

解决方法：

mysql> SET PASSWORD = PASSWORD('mysql');
