前言
如今紅帽Linux上默認是沒有yum源的mysql
yum軟件倉庫裏面只有MariaDB的安裝包因此咱們須要本身先配置yum源sql
實驗準備(如下操做在VMware中進行)
一臺Linux主機 (我這裏用的是RHEL7.4)
已經聯網
不要掛載yum鏡像
數據庫
一、配置yum源
下載yum源(我這裏已經找好了)this
wget 'https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm'
yum源下載連接:MySQLspa
安裝yum源code
rpm -Uvh mysql57-community-release-el7-11.noarch.rpm
查看有哪些版本的mysqlorm
yum repolist all | grep mysql
二、安裝
yum install -y mysql-community-server
三、啓動mysql
注意啓動的時候是mysqld而不是mysqlserver
systemctl start mysqld
查看狀態教程
systemctl status mysqld
四、登陸數據庫,修改數據庫密碼
找到密碼: 紅框的地方就是密碼get
[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log 2020-12-18T15:15:55.572640Z 1 [Note] A temporary password is generated for root@localhost: 9sX3oDXGti)P 密碼:9sX3oDXGti)P
五、登陸MySQL
[root@localhost ~]# mysql -uroot -p'9sX3oDXGti)P' mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.32 Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> ---出現這個表示登陸成功
查看數據庫
mysql>show databases; ---這裏會報錯,須要從新修改密碼 ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
修改密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'XXGC.lab123'; Query OK, 0 rows affected (0.01 sec) ---表示修改爲功
刷新
mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
退出
mysql> exit
六、使用新密碼登陸數據庫
[root@localhost ~]# mysql -uroot -p'XXGC.lab123' mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.32 MySQL Community Server (GPL) Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> ---登陸成功
查看一下
mysql> show databses; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0.00 sec) mysql>
以上就是在RHEL7.4中配置MySQL的教程
