在MySQL官網上下載最新版的Ubuntu Linux專用的MySQL。我這里下載的是：
mysql-server_5.7.17-1ubuntu16.04_amd64.deb-bundle.tar
也可從以下mirrors下載：
http://mirrors.sohu.com/mysql/MySQL-5.7/
解壓文件 命令為：
root@ubuntu:/# tar -zxvf mysql-server_5.7.17-1ubuntu16.04_amd64.deb-bundle.tar -C ./opt/
解壓開來后，一共有11個deb包，用sudo dpkg -i [包名]命令逐個安裝，因為包與包中間存在依賴關系，這里安裝有個先后順序。

我的安裝的順序是：
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
這里需要再安裝一個依賴包叫libmecab2,安裝好后，繼續安裝最后一個：
8.mysql-community-server_5.7.17-1ubuntu16.04_amd64.deb
安裝過程中需要設置數據庫密碼。
到這里，所有的已經安裝完畢。輸入Mysql -u root -p可以登陸數據庫了。
mysql簡單安裝方式：
1. sudo apt-get install mysql-server
2. apt-get isntall mysql-client
3. sudo apt-get install libmysqlclient-dev
安裝過程中會提示設置密碼什么的，注意設置了不要忘了，安裝完成之后可以使用如下命令來檢查是否安裝成功：
sudo netstat -tap | grep mysql
通過上述命令檢查之后，如果看到有mysql 的socket處於 listen 狀態則表示安裝成功。
登陸mysql數據庫可以通過如下命令：
mysql -u root -p
-u 表示選擇登陸的用戶名， -p 表示登陸的用戶密碼，上面命令輸入之后會提示輸入密碼，此時輸入密碼就可以登錄到mysql。
然后通過 show databases; 就可以查看當前的數據庫。
我們選擇 mysql數據庫就行下一步操作，使用use mysql 命令，顯示當前數據庫的表單：show tables;
mysql下如何執行sql腳本
- mysql> create database mydatabase;
- Query OK, 1 row affected (0.00 sec)
- mysql> use mydatabase;
- Database changed
- mysql> source ./mysql.sql
- Query 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: 0
- Query 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安裝出現的問題：
安裝mysql server時產生軟件依賴問題：
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.
那就先安裝上：
sudo apt -get install libmecab2
然后mysql-community-server，mysql-server就能正常使用了
在ubuntu下安裝任何軟件都提示以下錯誤：
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).
解決方法：
刪除提示的kate和kscope兩個未完全安裝的軟件。
$sudo dpkg --purge kate
$sudo dpkg --purge kscope
