如果之前安装过mysql，请执行如下操作

-----------------------------------------------------------------

UBUNTU 彻底删除 MYSQL 然后重装 MYSQL

删除 mysql

sudo apt-get autoremove --purge mysql-server-5.0
sudo apt-get remove mysql-server
sudo apt-get autoremove mysql-server
sudo apt-get remove mysql-common //这个很重要
上面的其实有一些是多余的。

清理残留数据

dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

----------------------------------------------------------------------------

这里是正常的开始安装步骤：

1.在官网下载mysql安装包

2.将包上传至服务器，并将该文件解压
解压命令为：
tar –xvf mysql-server_5.6.28-1ubuntu14.04_amd64.deb-bundle.tar
解压后得到一系列的.deb文件。依次为：

libmysqlclient18_5.6.28-1ubuntu14.04_amd64.deb
libmysqlclient-dev_5.6.28-1ubuntu14.04_amd64.deb
libmysqld-dev_5.6.28-1ubuntu14.04_amd64.deb
mysql-client_5.6.28-1ubuntu14.04_amd64.deb
mysql-common_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-bench_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-client_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-server_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-source_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-test_5.6.28-1ubuntu14.04_amd64.deb
mysql-server_5.6.28-1ubuntu14.04_amd64.deb
mysql-testsuite_5.6.28-1ubuntu14.04_amd64.deb

3.安装文件
这里这些文件存在着依赖关系，如果一个一个安装，要安装顺序来安装：
sudo dpkg -i mysql-common_5.6.28-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqlclient18_5.6.28-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqlclient-dev_5.6.28-1ubuntu14.04_amd64.deb
sudo dpkg -i libmysqld-dev_5.6.28-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-community-server_5.6.28-1ubuntu14.04_amd64.deb
注意在安装mysql-community-server会要求输入root账户密码
sudo dpkg -i mysql-server_5.6.28-1ubuntu14.04_amd64.deb
到这里个人认为服务器应该可以使用了（未测试），但是mysql命令还不能使用
sudo dpkg -i mysql-community-client_5.6.28-1ubuntu14.04_amd64.deb
sudo dpkg -i mysql-client_5.6.28-1ubuntu14.04_amd64.deb
到这里，mysql的安装完成
还有几个文件没有用，用处现在不知道
mysql-community-bench_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-source_5.6.28-1ubuntu14.04_amd64.deb
mysql-community-test_5.6.28-1ubuntu14.04_amd64.deb
mysql-testsuite_5.6.28-1ubuntu14.04_amd64.deb

安装过程中可能会提示缺少依赖包，这里安装依赖包就好  比如：

这里安装一下 libmecab2    可能会在这出现输入数据库的密码界面

4.启动和停止mysql服务命令
/etc/init.d/mysql start
/etc/init.d/mysql stop
    
    


    
    
    
    

     
     
mysql的root账户,我在连接时通常用的是localhost或127.0.0.1,公司的测试服务器上的mysql也是localhost所以我想访问无法访问,测试暂停. 解决方法如下: 1,修改表,登录mysql数据库,切换到mysql数据库,使用sql语句查看"select host,user from user ;" mysql -u root -pvmwaremysql>use mysql; mysql>update user set host = '%' where user ='root'; mysql>select host,user from user; mysql>flush privileges; 注意:最后一句很重要,目的是使修改生效.如果没有写,则还是不能进行远程连接. 2,授权用户,你想root使用密码从任何主机连接到mysql服务器
     
     
GRANT ALL PRIVILEGES ON *.* TO'root'@'%' IDENTIFIED BY 'admin123' WITH GRANT OPTION; flush privileges; 
     
     
如果你想允许用户root从ip为192.168.1.104的主机连接到mysql服务器
     
     
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.104' IDENTIFIED BY 'admin123' WITH GRANT OPTION; flush privileges;

    
    
    
    


    
    
    
    

     
     我装的版本是2.7.16  打开配置文件my.cnf  里面跟以前不一样了 
     
     好像是指向其他文件:
    
    
    
    

     
     
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
     
     

     
     
网上找了下说是在/etc/mysql/mysql.conf.d里面，果然在路径/etc/mysql/mysql.conf.d/mysqld.cnf是真实的配置文件路径

     
     mysqld.cnf配置如下：
