yum、源码安装mysql5.7

一、yum安装

yum安装比较简单，只需要机器能上网，找到一些开源镜像站配置yum就能下载安装了

1.配置yum源

# vim /etc/yum.repos.d/mysql57.repo

[mysql57]
name=mysql5.7
baseurl=https://mirrors.ustc.edu.cn/mysql-repo/yum/mysql-5.7-community/el/7/x86_64/
enabled=1
gpgcheck=0

2. 安装

# yum install -y mysql-community-server

3.启动服务

# systemctl start mysqld

 4.登录

查找临时密码

# grep password /var/log/mysqld.log

# mysql -uroot -p

修改密码 

# ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

或者

# mysqladmin -u root -p'old_password' pass
