1 SUDO權(quán)限及機器名標(biāo)準化
使用root用戶登錄：
1）添加用戶hadoop
groupadd hadoop
useradd -g hadoop hadoop
passwd hadoop dtsw1234
2）sudo權(quán)限配置
chmod u+w /etc/sudoers
vim /etc/sudoers
...
hadoop ALL=(ALL) NOPASSWD:ALL
...
chmod u-w /etc/sudoers
【注：更改完成后記得關(guān)閉寫權(quán)限，sudoers修改注意位置，不可直接加至末尾或開頭】
使用hadoop用戶，機器名標(biāo)準化
sudo hostnamectl set-hostname dtsw-001
sudo vim /etc/hosts
11111.11.11.11? qq
2 SSH無密碼登錄
hadoop用戶執(zhí)行： ssh-keygen -t rsa?
ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@aa
3 安裝元數(shù)據(jù)庫（MySQL為例）
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
找到初始密碼，設(shè)置新密碼
grep 'temporary password' /var/log/mysqld.log
mysql -u root -p
mysql> Enter password: （輸入剛才查詢到的隨機密碼）
mysql> SET PASSWORD FOR 'root'@'da1'= "aaa";
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'aa' WITH
GRANT OPTION;
mysql>FLUSH PRIVILEGES;
創(chuàng)建ambari元數(shù)據(jù)庫
create database ambari character set utf8 ;
CREATE USER 'ambari'@'%'IDENTIFIED BY 'bigdata';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
FLUSH PRIVILEGES;
