ambari部署

1.环境信息

CentOS6.5	10.0.0.41	node1	mysql, ambari server
CentOS6.5	10.0.0.42	node2
CentOS6.5	10.0.0.43	node3

2.创建ambari用户并初始化密码
2.1创建用户

[root@node1 ~]# for i in {41..43}; do ssh 10.0.0.$i "groupadd ambari && useradd -g ambari -d /home/ambari ambari"; done

2.2初始化密码

[root@node1 ~]# for i in {41..43}; do ssh 10.0.0.$i "echo '123456' | passwd --stdin ambari"; done

3.ambari用户之间打通key
3.1生成key

#切换到ambari用户下
[root@node1 ~]# su - ambari
#执行keygen
[ambari@node1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/opt/ambari/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /opt/ambari/.ssh/id_rsa.
Your public key has been saved in /opt/ambari/.ssh/id_rsa.pub.
The key fingerprint is:
db:0f:64:75:d9:7a:4e:ce:e8:f0:96:96:24:71:c0:cd ambari@bgs-8p80-udp-01
The key's randomart image is:
+--[ RSA 2048]----+
| . o |
| o Eo |
| ..o .|
| ..... |
| S o o. o|
| = . .B |
| . o .o.o+|
| o += |
| .oo |
+-----------------+
[ambari@node1 ~]# for i in {41..43};do ssh-copy-id [email protected].$i;done
#此时需要输入一遍41-43的ambari密码

3.2验证是否打通

[ambari@node1 ~]# for i in {41..43};do ssh 10.0.0.$i "echo Ok";done
It's Ok
It's Ok
It's Ok
#此时输出3遍It's Ok即为没问题

4.root用户之间打通key
4.1生成key

[root@node1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
db:0f:64:75:d9:7a:4e:ce:e8:f0:96:96:24:71:c0:cd root@bgs-8p80-udp-01
The key's randomart image is:
+--[ RSA 2048]----+
| . o |
| o Eo |
| ..o .|
| ..... |
| S o o. o|
| = . .B |
| . o .o.o+|
| o += |
| .oo |
+-----------------+
[root@node1 ~]# for i in {41..43};do ssh-copy-id [email protected].$i;done
#此时需要输入一遍41-43的root密码

4.2验证是否打通

[root@node1 ~]# for i in {41..43};do ssh 10.0.0.$i "echo "It's Ok";done
It's Ok
It's Ok
It's Ok
#此时输出3遍It's Ok即为没问题

5.ambari数据库创建

[ambari@node1 soft]# mysql -uroot -p
mysql> create database ambari character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> create user ambari identified by 'baifendian';
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on ambari.* to 'ambari'@'localhost' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> grant all privileges on ambari.* to 'ambari'@'172.24.8.80' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on ambari.* to 'ambari'@'bgs-8p80-maxin' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on ambari.* to 'ambari'@'%' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> quit;
Bye
[ambari@node1 soft]

6.hive数据库创建

[ambari@node1 soft]# mysql -uroot -p
mysql> create database hive character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> create user hive identified by 'baifendian';
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'localhost' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'172.24.8.80' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'bgs-8p80-maxin' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'%' identified BY '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
