Ubuntu18.04安裝mysql5.7

Ubuntu18.04安裝mysql5.7

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，緣由：root的plugin被修改爲了auth_socket，用密碼登錄的plugin應該是mysql_native_password，直接用root權限登陸就不用密碼,修改root密碼和登陸驗證方式：

$ 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.

1.3配置mysql遠程登陸

# 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，而後進入mysql服務，執行受權命令： $ 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
