Ubuntu18.04安裝mysql5.7，供大家參考，具體內容如下

1.1安裝

首先執行下面三條命令：

# 安裝mysql服務
sudo apt-get install mysql-server
# 安裝客戶端
sudo apt install mysql-client
# 安裝依賴
sudo apt install libmysqlclient-dev
# 檢查狀態
sudo netstat -tap | grep mysql

1.2設定root密碼

mysql5.7安裝完成後普通使用者不能進mysql，原因：root的plugin被修改成了auth_socket，用密碼登陸的plugin應該是mysql_native_password，直接用root許可權登入就不用密碼,修改root密碼和登入驗證方式：

$ sudo su
# mysql
mysql>
mysql> select user,plugin from mysql.user;
+------------------+-----------------------+
| user | plugin |
+------------------+-----------------------+
| root | auth_socket |
| mysql.session | mysql_native_password |
| mysql.sys | mysql_native_password |
| debian-sys-maint | mysql_native_password |
+------------------+-----------------------+
4 rows in set (0.00 sec)
mysql> update mysql.user set authentication_string=PASSWORD('123456'),plugin='mysql_native_password' where user='root';
mysql> flush privileges;
mysql> exit
Bye
# exit
$ sudo /etc/init.d/mysql restart
$ mysql -uroot -p

Enter password:

1.3配置mysql遠端登入

# 修改配置檔案，註釋掉bind-address = 127.0.0.1
$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

# 儲存退出，然後進入mysql服務，執行授權命令：
$ mysql -uroot -p

mysql> grant all on *.* to root@'%' identified by '123456' with grant option;
Query OK,0 rows affected,1 warning (0.00 sec)

mysql> flush privileges;
Query OK,0 rows affected (0.00 sec)

mysql> exit
Bye
$ sudo /etc/init.d/mysql restart
