五、安装ambari-server
yum -y install ambari-server
六、安装MariaDB数据库并配置数据库
1、安装MariaDB数据库
yum -y install mariadb-server systemctl enable mariadb.service systemctl start mariadb.service netstat -anp | grep 3306
2、设置数据库初始密码
mysqladmin -uroot password "ambari"
3、设置可以远程登录
mysql -uroot -pambari grant all privileges on *.* to 'root'@'ambari' identified by 'ambari' with grant option; grant all privileges on *.* to 'root'@'10.20.90.59' identified by 'ambari' with grant option; flush privileges; systemctl restart mariadb.service
4、创建ambari数据库
mysql -uroot -pambari -hambari create database ambari DEFAULT CHARSET utf8; use ambari source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
七、ambari-server初始化配置
[root@ambari home]# ambari-server setup Using python /usr/bin/python Setup ambari-server Checking SELinux... SELinux status is 'disabled' Customize user account for ambari-server daemon [y/n] (n)? y Enter user account for ambari-server daemon (root):root Adjusting ambari-server permissions and ownership...

拷贝jdbc驱动包，并在ambari.properties配置文件中添加jdbc驱动的配置
mkdir /usr/share/java cp /home/mysql-connector-java-8.0.20.jar /usr/share/java/mysql-connector-java.jar vi /etc/ambari-server/conf/ambari.properties #追加一行 server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar
ambari-server start
八、ambari web界面向导搭建集群
注意：这里的URL最后面的/斜杠需要去掉，（图误）
九、排错
1、Confirm Hosts时出现安装ambari-agent的报错的解决方法
修改 /etc/ambari-agent/conf/ambari-agent.ini 文件，在 [security] 配置部分添加 [security] ... force_https_protocol=PROTOCOL_TLSv1_2
2、yum.conf配置文件修改
vi /etc/yum.conf installonly_limit=5改为 installonly_limit=600
