1, 用 root 操作；
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 属性值修改为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
vi /etc/ntp.conf
注释掉所有server ..*的指向，新添加一条可连接的ntp服务器(我选的本公司的ntp测试服务器)
server cn.pool.ntp.org iburst
在其他节点上把ntp指向master服务器地址即可(/etc/ntp.conf下) server master iburst
重启ntp服务 service ntpd restart
开机启动 systemctl enable ntpd.service
重新启动 ntp 服务：service ntpd restart
设置开机自启：systemctl enable ntpd.service
查看与时间同步服务器的时间偏差ntpdc -c loopinfo
查看当前同步的时间服务器 ntpq -p
节点服务器的同步服务器是master服务器即可
免密登录
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:
tar -xvf mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar
yum -y localinstall mysql-community-common-5.7.31-1.el7.x86_64.rpm
yum -y localinstall mysql-community-libs-5.7.31-1.el7.x86_64.rpm
yum -y localinstall mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm
yum -y localinstall mysql-community-devel-5.7.31-1.el7.x86_64.rpm
yum -y localinstall mysql-community-client-5.7.31-1.el7.x86_64.rpm
yum -y localinstall mysql-community-server-5.7.31-1.el7.x86_64.rpm
如果出现mariadb lib冲突,卸载
yum remove mariadb
yum list installed | grep mariadb
yum remove mariadb-libs
将其卸载
rm -rf /etc/my.cnf
或：
rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
yum -y install mysql-community-server --nogpgcheck
启动
systemctl start mysqld
开机自启动
systemctl enable mysqld
查看临时密码
cat /var/log/mysqld.log | grep password
临时密码填充到引号内，执行
mysql -uroot -p'ly0h!Gw4PyBk'
修改密码:
降低密码校验规则,生产环境慎用
set global validate_password_length=4;
set global validate_password_policy=0;
set password=PASSWORD('root');
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
flush privileges;
外网绑定:
/etc/mysql/my.cnf
创建库
create database cmf default character set = 'utf8';
create database amon default character set = 'utf8';
create database hive default character set = 'latin1';
create database hue default character set = 'utf8';
create database oozie default character set = 'utf8';
quit;
所有节点保存数据库驱动文件
mv mysql-connector-java-5.1.40.jar mysql-connector-java.jar
mkdir /usr/share/java
mv mysql-connector-java.jar /usr/share/java/
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
查看防火墙状态
firewall-cmd --state
selinux关闭
apt install selinux-utils -y
setenforce 0
vi /etc/selinux/config
SELINUX=disabled
禁用透明页(所有节点）
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
永久生效 在/etc/rc.local 添加上面命令
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
如果机子内存小，cpu 慢，修改安装超时时间:
vim /etc/ambari-server/conf/ambari.properties
agent.package.install.task.timeout=1800
改为2700
过程截图:
1,check warning 必须全部处理:
选主从:
ambari 从本地数据源下载太慢，则必须做本地仓库:
https://docs.hortonworks.com/,ambari, 根据版本找
下载本地数据
异常记录:
1, 节点 cpu 和内存不能太小，否则会发生 cpu 或者内存吃光的现象，导致相互无法通讯:
2, 配置 hive 数据库，jdbc 地址，3306 默认没有配置，要自己加！
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:
安装成功:
8088
