添加源rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm安装yum install php70w

1.安装wget  yum -y install wget2.安装源  wget https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm  rpm -ivh mysql57-community-release-el7-8.noarch.rpm3.安装mysql  yum install mysql-server4.启动mysql服务  systemctl start mysqld5.查看MySQL的启动状态  systemctl status mysqld6.开机启动  systemctl enable mysqld  systemctl daemon-reload7.修改root本地登录密码  查找mysql生成的随机密码  grep 'temporary password' /var/log/mysqld.log  mysql -uroot -p  修改密码，注意：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误  ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!'; 8.配置默认编码为utf8  修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置  [mysqld]  character_set_server=utf8  init_connect='SET NAMES utf8'9.配置mysql远程连接  mysql -uroot -p  use mysql;  Grant all on *.* to 'root'@'%' identified by 'root用户的密码' with grant option;flush privileges;然后用以下命令查看哪些用户和host可以访问，%代表任意ip地址select user,host from user;防火墙添加3306端口firewall-cmd --zone=public --add-port=3306/tcp --permanentfirewall-cmd --reload10.mysql忘记密码1.修改MySQL的配置文件（默认为/etc/my.cnf）,在[mysqld]下添加一行skip-grant-tables2.service mysqld restart后，即可直接用mysql进入3.mysql> update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';  mysql> flush privileges;  mysql> quit; 将/etc/my.cnf文件还原，重新启动mysql:service mysql restart,这个时候可以使用mysql -u root -p'123qwe'进入了 mysql>SET PASSWORD = PASSWORD('newpasswd'); 设置新密码
