ubuntu 16.04安装mysql-server_5.7.17

在MySQL官网上下载最新版的Ubuntu Linux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sudo dpkg -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 -u root -p可以登陆数据库了。

mysql简单安装方式：

1. sudo apt-get install mysql-server

2. apt-get isntall mysql-client

3.  sudo apt-get install libmysqlclient-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：

sudo netstat -tap | grep mysql

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 -u root -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 show databases; 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use mysql 命令，显示当前数据库的表单：show tables

mysql下如何执行sql脚本

mysql> create database mydatabase;Query OK, 1 row affected (0.00 sec)mysql> use mydatabase;Database changedmysql> source ./mysql.sqlQuery OK, 0 rows affected, 1 warning (0.00 sec)Query OK, 0 rows affected (0.00 sec)Query OK, 0 rows affected (0.33 sec)Records: 0  Duplicates: 0  Warnings: 0Query OK, 0 rows affected, 1 warning (0.00 sec)Query OK, 0 rows affected (0.00 sec)Query OK, 0 rows affected, 1 warning (0.00 sec)Query OK, 0 rows affected (0.04 sec)Query OK, 0 rows affected, 1 warning (0.00 sec)Query OK, 0 rows affected (0.00 sec)mysql> show tables;

dpkg安装出现的问题：

安装mysql server时产生软件依赖问题： 
mysql-community-server depends on apparmor; however: 
Package apparmor is not installed. 
mysql-community-server depends on libmecab2 (>= 0.996-1.2ubuntu1); however: 
Package libmecab2 is not installed. 
那就先安装上： 
sudo apt -get install libmecab2 
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：

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 kate : Depends: kdelibs4c2a (>= 4:3.5.9) but it is not going to be installed
        Depends: libqt3-mt (>= 3:3.3.8b) but it is not going to be installed
        Recommends: kregexpeditor but it is not installable
 kscope : Depends: kdelibs4c2a (>= 4:3.5.7-1) but it is not going to be installed
          Depends: libaudio2 but it is not going to be installed
          Depends: libqt3-mt (>= 3:3.3.8really3.3.7) but it is not going to be installed
          Depends: cscope but it is not going to be installed
          Depends: exuberant-ctags but it is not going to be installed
          Depends: graphviz but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

解决方法：

     删除提示的kate和kscope两个未完全安装的软件。

    $sudo dpkg --purge kate

    $sudo dpkg --purge kscope
