这是查看centos版本的命令
cat /etc/redhat-release

# 设置centos的阿里镜像源。
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum install -y wget epel-release
yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm


yum install -y yum-utils

## 设置epel的阿里镜像源。
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

  
yum-config-manager --enable remi-php72

# 设置remi 的清华大学镜像源。
yum-config-manager --setopt=remi-php72.baseurl="https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/7/php72/$basearch/" --save

yum-config-manager --setopt=remi-php56.baseurl="https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/7/php56/$basearch/" --save

yum install -y mysql57-community-release-el7-11.noarch.rpm
yum install -y mysql-community-server
systemctl start mysqld

# 这一步查看到初始密码
grep "password" /var/log/mysqld.log

# 这一步输入刚才的初始密码
mysql -uroot -p
 
  # 以下语句在mysql的shell里执行，最后一句是设置密码
  set global validate_password_policy=0;
