ambari的安装

一、环境初始化

1、配置yum源

用的公司配好的yum源，可以自己配置，repo文件也需要放到agent端机器。

[root@hadoop1 yum.repos.d]# cat ambari.repo #VERSION_NUMBER=2.5.1.0-159[ambari-2.5.1.0]name=ambari Version - ambari-2.5.1.0baseurl=http://mirror.xxxx.com/yum/ambari/centos6/gpgcheck=1gpgkey=http://mirror.xxxx.com/yum/ambari/centos6/RPM-GPG-KEY/RPM-GPG-KEY-Jenkinsenabled=1priority=1

2、时间同步

最简单的是手同步执行date -s 'xxx:xxx:xxx'
ntp时间同步服务器

3、检查防火墙

[root@hadoop1 opt]# service iptables status[root@hadoop1 opt]# service iptables stop

4、检查java是否安装

jdk的tar包安装

5、mysql的安装

mysql-5.5.39版本的安装
mysql-5.7.20版本的安装

二、准备工作

1、ambari数据库创建

[ambari@hadoop1 opt]# mysql -uroot -pmysql> create database ambari character set utf8;mysql> create user ambari identified by '1234';mysql> grant all privileges on ambari.* to 'ambari'@'localhost' identified by '1234';mysql> grant all privileges on ambari.* to 'ambari'@'%' identified by '1234';mysql> grant all privileges on ambari.* to 'ambari'@'192.168.30.145' identified by '1234';mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> quit;Bye

三、ambari的安装

[root@hadoop1 opt]# yum install ambari-server

[root@hadoop1 opt]# ambari-server setup

解决方案：

#除了server端要升级mysql-connetor,agent端也需要安装，切记。[root@hadoop1 opt]# yum install mysql-connector-java -y[root@hadoop1 opt]# cd /usr/share/java/[root@hadoop1 java]# ls

设置Setup-JDBC

[root@hadoop1 opt]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jarUsing python  /usr/bin/pythonSetup ambari-serverCopying /usr/share/java/mysql-connector-java.jar to /var/lib/ambari-server/resourcesIf you are updating existing jdbc driver jar for mysql with mysql-connector-java.jar. Please remove the old driver jar, from all hosts. Restarting services that need the driver, will automatically copy the new jar to the hosts.JDBC driver was successfully initialized.Ambari Server 'setup' completed successfully.

启动ambari

[root@hadoop1 opt]# ambari-server start
