1 SUDO权限及机器名标准化
使用root用户登录：
1）添加用户hadoop
groupadd hadoop
useradd -g hadoop hadoop
passwd hadoop dtsw1234
2）sudo权限配置
chmod u+w /etc/sudoers
vim /etc/sudoers
...
hadoop ALL=(ALL) NOPASSWD:ALL
...
chmod u-w /etc/sudoers
【注：更改完成后记得关闭写权限，sudoers修改注意位置，不可直接加至末尾或开头】
使用hadoop用户，机器名标准化
sudo hostnamectl set-hostname dtsw-001
sudo vim /etc/hosts
11111.11.11.11 qq
2 SSH无密码登录
hadoop用户执行： ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@aa
3 安装元数据库（MySQL为例）
wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
sudo rpm -ivh mysql57-community-release-el7-8.noarch.rpm --nodeps --force
sudo yum install mysql-server
sudo systemctl start mysqld
sudo systemctl enable mysqld
找到初始密码，设置新密码
grep 'temporary password' /var/log/mysqld.log
mysql -u root -p
mysql> Enter password: （输入刚才查询到的随机密码）
mysql> SET PASSWORD FOR 'root'@'da1'= "aaa";
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'aa' WITH
GRANT OPTION;
mysql>FLUSH PRIVILEGES;
创建ambari元数据库
create database ambari character set utf8 ;
CREATE USER 'ambari'@'%'IDENTIFIED BY 'bigdata';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
FLUSH PRIVILEGES;
