前段时间搞了个阿里云服务器自己玩玩,jdk以及Tomcat都安装好了,就剩下MySQL数据库不会安装,在网上找了很多教程也没有安装成功。后来一次偶然,发现了一个资源,就试着安装,没成想真的安装好了,就记录下了本次MySQL数据库安装的大概步骤。
阿里云服务器MySQL数据库配置
mysql安装:
1.检查系统中是否已安装了MySQL
rpm -qa|grep mysql
2.如果有,建议先卸载
yum -y remove mysql
yum -y remove ...
rm -rf /var/lib/mysql/
3.新建一个software文件夹下载:
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
4.安装yum源
rpm -ivh mysql57-community-release-el7-8.noarch.rpm
5.安装MySQL
yum -y install mysql-server
6.启动MySQL
systemctl start mysqld
7.检查MySQL的状态
service mysqld status
8.如何获取MySQL产生的随机密码
grep "temporary password" /var/log/mysqld.log
9.登录MySQL
mysql -uroot -p
10.更改MySQL(8.0以上)密码:
alter user 'root'@'localhost' IDENTIFIED BY '123456';
