Ubuntu18.04安裝mysql5.7，供大家參考，具體內(nèi)容如下
1.1安裝
首先執(zhí)行下面三條命令：
# 安裝mysql服務(wù)
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(tài)
sudo netstat -tap | grep mysql
1.2設(shè)置root密碼
mysql5.7安裝完成后普通用戶不能進mysql，原因：root的plugin被修改成了auth_socket，用密碼登陸的plugin應(yīng)該是mysql_native_password，直接用root權(quán)限登錄就不用密碼,修改root密碼和登錄驗證方式：
$ 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遠程登錄
# 修改配置文件，注釋掉bind-address = 127.0.0.1
$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf
# 保存退出，然后進入mysql服務(wù)，執(zhí)行授權(quán)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
