1.安裝wget  yum -y install wget2.安裝源  wget https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm  rpm -ivh mysql57-community-release-el7-8.noarch.rpm3.安裝mysql  yum install mysql-server4.啟動mysql服務  systemctl start mysqld5.查看MySQL的啟動狀態  systemctl status mysqld6.開機啟動  systemctl enable mysqld  systemctl daemon-reload7.修改root本地登錄密碼  查找mysql生成的隨機密碼  grep 'temporary password' /var/log/mysqld.log  mysql -uroot -p  修改密碼，注意：mysql5.7默認安裝了密碼安全檢查插件（validate_password），默認密碼檢查策略要求密碼必須包含：大小寫字母、數字和特殊符號，并且長度不能少于8位。否則會提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements錯誤  ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!'; 8.配置默認編碼為utf8  修改/etc/my.cnf配置文件，在[mysqld]下添加編碼配置  [mysqld]  character_set_server=utf8  init_connect='SET NAMES utf8'9.配置mysql遠程連接  mysql -uroot -p  use mysql;  Grant all on *.* to 'root'@'%' identified by 'root用戶的密碼' with grant option;flush privileges;然后用以下命令查看哪些用戶和host可以訪問，%代表任意ip地址select user,host from user;防火墻添加3306端口firewall-cmd --zone=public --add-port=3306/tcp --permanentfirewall-cmd --reload10.mysql忘記密碼1.修改MySQL的配置文件（默認為/etc/my.cnf）,在[mysqld]下添加一行skip-grant-tables2.service mysqld restart后，即可直接用mysql進入3.mysql> update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';  mysql> flush privileges;  mysql> quit; 將/etc/my.cnf文件還原，重新啟動mysql:service mysql restart,這個時候可以使用mysql -u root -p'123qwe'進入了 mysql>SET PASSWORD = PASSWORD('newpasswd'); 設置新密碼
