ambari安装注意事项

官方教程:https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html

1,用root操做;

设置ip:
vi /etc/network/interface
static
address 192.168.199.210
netmask 255.255.255.0
geteway 192.168.199.1
dns-nameservers 114.114.114.114
网卡重启
sudo ifdown eth0 && sudo ifup eth0
root密码初始化
sudo passwd root
root ssh启用 
sudo vi /etc/ssh/sshd_config

PermitRootLogin -> yes 属性值修改成yes
#AuthorizedKeysFile      %h/.ssh/authorized_keys 启用删除#

主机名,host映射修改
vim /etc/hostname  
vim /etc/hosts
xinju.master
xinju.slave1
xinju.slave2
或者用命令
hostname xxxx

修改hostname,重启生效
时间同步:
sudo apt-get install ntp -y 
root@com:~# systemctl restart ntp
免密登陆
ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub root@com.mt.master
ssh-copy-id -i ~/.ssh/id_rsa.pub root@com.mt.slave001
ssh-copy-id -i ~/.ssh/id_rsa.pub root@com.mt.slave002

本地数据库安装:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
flush privileges;
外网绑定:
/etc/mysql/my.cnf
关闭防火墙
ufw disable
sudo iptables -X
sudo iptables -t nat -F
sudo iptables -t nat -X
sudo iptables -t mangle -F
sudo iptables -t mangle -X
sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT

ulimit -n 10000

selinux关闭
apt install selinux-utils -y 
setenforce 0

umask
umask 0022
echo umask 0022 >> /etc/profile

禁用大内存页面 
echo never > /sys/kernel/mm/transparent_hugepage/enabled

2,添加源ambari源

wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.5.1.0/ambari.list
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD
apt-get update
apt-get install ambari-server -y

 

安装

apt-get install install ambari-server &&　ambari-server setup && ambari-server start

若是机子内存小,cpu慢,修改安装超时时间:

vim /etc/ambari-server/conf/ambari.properties

agent.package.install.task.timeout=1800
改成2700

过程截图:

1,check warning必须所有处理:

选主从:

ambari从本地数据源下载太慢,则必须作本地仓库:

https://docs.hortonworks.com/,ambari,根据版本找

下载本地数据

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-installation/content/ambari_repositories.html

异常记录:

1,节点cpu和内存不能过小,不然会发生cpu或者内存吃光的现象,致使相互没法通信:

2,配置hive数据库,jdbc地址,3306默认没有配置,要本身加!

血的教训

 

阿里云服务器bug也是多:

1,买服务器的时候,选中三台slave,下订单点两下结果出来6台,(⊙﹏⊙)b,

2,100m最大带宽,给我干到150m,有图为证:
