這篇文章主要爲大家詳細介紹了Ubuntu 18.04 安裝mysql 5.7的相關資料,具有一定的參考價值,感興趣的小夥伴們可以參考一下
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設置root密碼
mysql5.7安裝完成後普通用戶不能進mysql,原因:root的plugin被修改成了auth_socket,用密碼登陸的plugin應該是mysql_native_password,直接用root權限登錄就不用密碼,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: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.22-0ubuntu18.04.1 (Ubuntu) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
1.3配置mysql遠程登錄
# 修改配置文件,註釋掉bind-address = 127.0.0.1 $ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf # 保存退出,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
