linux环境搭建之mysql

此次安装，是基于Centos7版本，未安装任何软件！！！
照着我的history安装，一把过的几率是99.99%，所以在此就不对各类异常的解决方案进行举例了

1.Yum的安装
首先执行命令安装Yum，是为了可以使用yum去安装其他的东西

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

2.Yum安装rpm

yum -y install mysql57-community-release-el7-10.noarch.rpm

3.MYSQL的安装

yum -y install mysql-community-server 

4.MYSQL的启动

systemctl start  mysqld.service 

5.MYSQL的状态查看

systemctl status mysqld.service

6.MYSQL的密码查看

grep password /var/log/mysqld.log

7.MYSQL登陆
mysql -u root -p 执行后输入密码

8.MYSQL密码修改

ALTER USER 'root'@'localhost' IDENTIFIED BY 'z?guwrBhH7p>';

如果不成功则exit退出mysql重试，试了好几次不行于是系统重装，但我发现直接复制就是ok的

9.本地MYSQL的连接
首先授权 grant all privileges on *.* to root@'%' identified by 'z?guwrBhH7p>' with grant option;
然后在腾讯云的本地规则中将端口号加入即可

10.执行过的history（不要怂，直接复制）
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
systemctl start mysqld.service
systemctl status mysqld.service
grep “password” /var/log/mysqld.log
mysql -u root -p
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘z?guwrBhH7p>’;
grant all privileges on . to root@’%’ identified by ‘z?guwrBhH7p>’ with grant option;
