mysql 5.7.17 安装配置方法图文教程（ubuntu 16.04）
在MySQL官网上下载最新版的UbuntuLinux专用的MySQL。我这里下载的是：
mysql-server_5.7.17-1ubuntu16.04_amd64.deb-bundle.tar
也可从以下mirrors下载：
http://mirrors.sohu.com/mysql/MySQL-5.7/
解压文件命令为：
root@ubuntu:/fly/mysql#tar-xvf../mysql-server_5.7.17-1ubuntu16.04_amd64.deb-bundle.tar-C./
解压开来后，一共有11个deb包，用sudodpkg-i[包名]命令逐个安装，因为包与包中间存在依赖关系，这里安装有个先后顺序。

我的安装的顺序是：
1.mysql-common_5.7.17-1ubuntu16.04_amd64.deb
2.libmysqlclient20_5.7.17-1ubuntu16.04_amd64.deb
3.libmysqlclient-dev_5.7.17-1ubuntu16.04_amd64.deb
4.libmysqld-dev_5.7.17-1ubuntu16.04_amd64.deb
5.mysql-community-client_5.7.17-1ubuntu16.04_amd64.deb
6.mysql-client_5.7.17-1ubuntu16.04_amd64.deb
7.mysql-community-source_5.7.17-1ubuntu16.04_amd64.deb
这里需要再安装一个依赖包叫libmecab2，安装好后，继续安装最后一个：
8.mysql-community-server_5.7.17-1ubuntu16.04_amd64.deb
安装过程中需要设置数据库密码。
到这里，所有的已经安装完毕。输入Mysql-uroot-p可以登陆数据库了。

mysql简单安装方式：
1.sudoapt-getinstallmysql-server
2.apt-getisntallmysql-client
3. sudoapt-getinstalllibmysqlclient-dev
安装过程中会提示设置密码什么的，注意设置了不要忘了，安装完成之后可以使用如下命令来检查是否安装成功：
sudonetstat-tap|grepmysql
通过上述命令检查之后，如果看到有mysql的socket处于listen状态则表示安装成功。
登陆mysql数据库可以通过如下命令：
mysql-uroot-p
-u表示选择登陆的用户名，-p表示登陆的用户密码，上面命令输入之后会提示输入密码，此时输入密码就可以登录到mysql。
然后通过showdatabases;就可以查看当前的数据库。
我们选择mysql数据库就行下一步操作，使用usemysql命令，显示当前数据库的表单：showtables
mysql下如何执行sql脚本
mysql>createdatabasemydatabase; QueryOK,1rowaffected(0.00sec) mysql>usemydatabase; Databasechanged mysql>source./mysql.sql QueryOK,0rowsaffected,1warning(0.00sec) QueryOK,0rowsaffected(0.00sec) QueryOK,0rowsaffected(0.33sec) Records:0Duplicates:0Warnings:0 QueryOK,0rowsaffected,1warning(0.00sec) QueryOK,0rowsaffected(0.00sec) QueryOK,0rowsaffected,1warning(0.00sec) QueryOK,0rowsaffected(0.04sec) QueryOK,0rowsaffected,1warning(0.00sec) QueryOK,0rowsaffected(0.00sec) mysql>showtables;
dpkg安装出现的问题：
安装mysqlserver时产生软件依赖问题：
mysql-community-serverdependsonapparmor;however:
Packageapparmorisnotinstalled.
mysql-community-serverdependsonlibmecab2(>=0.996-1.2ubuntu1);however:
Packagelibmecab2isnotinstalled.
那就先安装上：
sudoapt-getinstalllibmecab2
然后mysql-community-server，mysql-server就能正常使用了
在ubuntu下安装任何软件都提示以下错误：

解决方法：
删除提示的kate和kscope两个未完全安装的软件。
