    qianfeng03
    

免密登陆

  • 生产密钥
ssh-keygen -t rsa   一路回车即可
  • 分发密钥,分发给自己就行了,克隆后再ssh

    语法格式:ssh-copy-id -i 公钥文件 远程用户名@远程机器IP
    
    作用:将本机当前用户的公钥文件,复制到远程机器的相关用户的主目录的隐藏目录.ssh下,同时自动更名为authorised_keys.
    
    注意:.ssh目录的权限是700
    	authorised_keys的权限是600
    

firewalld和NetworkManager以及selinux的关闭

查看服务状态:	systemctl status firewalld

临时关闭:	systemctl stop firewalld
临时启动:	systemctl start firewalld

设置开机不启动: systemctl disable firewalld        	#下次开机生效
设置开机启动: 	systemctl enable firewalld		#下次开机生效



systemctl  status NetworkManager
systemctl  start   NetworkManager
systemctl  stop  NetworkManager
systemctl  disable NetworkManager
systemctl  enable  NetworkManager


[root@nz202 ~]# vi /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing		<----  需要将enforcing改为disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

克隆虚拟机

  • 修改主机名

    ]# hostnamectl set-hostname qianfeng02
    
  • 修改IP

    [root@qianfeng02 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
    
    TYPE=Ethernet
    BOOTPROTO=static
    NAME=ens33
    DEVICE=ens33
    ONBOOT=yes
    
    
    IPADDR=192.168.10.102			<--- 修改ip地址即可,别的都不用动
    NETMASK=255.255.255.0
    GATEWAY=192.168.10.2
    DNS1=192.168.10.2
    DNS2=8.8.8.8
    DNS3=114.114.114.114
    
  • 重启网络并检查ip

    systemctl restart network
    ip addr
    
    ping外网
    ping主机
    主机ping虚拟机mysql的安装
    

mysql的安装

  • 上传安装包,解压

    [root@qianfeng01 ~]# tar -xvf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar -C /usr/local/mysql
    
    mysql-community-embedded-5.7.28-1.el7.x86_64.rpm
    mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm
    mysql-community-devel-5.7.28-1.el7.x86_64.rpm
    mysql-community-embedded-compat-5.7.28-1.el7.x86_64.rpm
    mysql-community-libs-5.7.28-1.el7.x86_64.rpm
    mysql-community-test-5.7.28-1.el7.x86_64.rpm
    mysql-community-common-5.7.28-1.el7.x86_64.rpm
    mysql-community-embedded-devel-5.7.28-1.el7.x86_64.rpm
    mysql-community-client-5.7.28-1.el7.x86_64.rpm
    mysql-community-server-5.7.28-1.el7.x86_64.rpm
    
  • 安装mysql所依赖的环境perl,移除mysql的冲突软件mariadb

    [root@qianfeng01 ~]# yum -y install perl
    [root@qianfeng01 ~]# yum -y install net-tools
    [root@qianfeng01 ~]# rpm -qa | grep mariadb
    mariadb-libs-5.5.64-1.el7.x86_64
    [root@qianfeng01 ~]# rpm -e mariadb-libs-5.5.64-1.el7.x86_64 --nodeps
    
  • 按照mysql的依赖顺序来安装mysql的rpm包

    [root@qianfeng01 ~]# rpm -ivh mysql-community-common-5.7.28-1.el7.x86_64.rpm
    [root@qianfeng01 ~]# rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm
    [root@qianfeng01 ~]# rpm -ivh mysql-community-client-5.7.28-1.el7.x86_64.rpm
    [root@qianfeng01 ~]# rpm -ivh mysql-community-server-5.7.28-1.el7.x86_64.rpm
    
  • 启动mysql的服务项,并检查状态

    [root@qianfeng01 ~]# systemctl start mysqld
    [root@qianfeng01 ~]# systemctl status mysqld
    ● mysqld.service - MySQL Server
       Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
       Active: active (running) since 五 2020-05-29 11:25:57 CST; 9s ago
         Docs: man:mysqld(8)
               http://dev.mysql.com/doc/refman/en/using-systemd.html
      Process: 2406 ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS (code=exited, status=0/SUCCESS)

    5月 29 11:25:57 qianfeng01 systemd[1]: Started MySQL Server.
    
  • 查询mysql的初始密码(密码保存在/var/log/mysqld.log文件中,此文件是服务项启动后生成的)

    [root@qianfeng01 ~]# cat /var/log/mysqld.log | grep password
    
  • 使用初始密码进行登录

    [root@qianfeng01 ~]# mysql -uroot -p‘密码‘
    
  • 登录成功后,要降低密码策略机制,改为low,也可以将密码长度6.

    set global validate_password_policy=low;
    set global validate_password_length=6;
    
    查看密码策略,是否修改成功
    show variables like ‘%validate_password%‘;
    
  • 修改密码

    alter user root@localhost identified by ‘新密码‘
    
  • 如果想要远程连接mysql,需要进行远程授权操作(注意,一定要关闭虚拟机防火墙)

    *.*:所有库下的所有表
    root@“%”:root下的所有ip
    
    grant all privileges on *.* to root@"%" identified by ‘111111‘ with grant option;
    

hive的安装

  • 上传解压,更名

    [root@qianfeng01 local]# tar -zxvf apache-hive-2.1.1-bin.tar.gz -C /usr/local
    [root@qianfeng01 local]# mv apache-hive-2.1.1-bin/ hive
    
  • 环境变量的配置

    [root@qianfeng01 local]# vi /etc/profile 
    # 添加如下内容: 
    export HIVE_HOME=/usr/local/hive 
    export PATH=$HIVE_HOME/bin:$PATH #让profile生效 [root@qianfeng01 local
    ]# source /etc/profile
    
  • hive-env.sh

    export HIVE_CONF_DIR=/usr/local/hive/conf 
    export JAVA_HOME=/usr/local/jdk 
    export HADOOP_HOME=/urs/local/hadoop 
    export HIVE_AUX_JARS_PATH=/usr/local/hive/lib
    
  • hive-site.xml

hbase完全分布式

安装zookeeper

  • 上传并解压更名

    [root@qianfeng01 ~]# tar -zxvf zookeeper-3.4.10.tar.gz -C /usr/local/
    [root@qianfeng01 ~]# cd /usr/local/ [root@qianfeng01 local]# mv zookeeper-3.4.10 zookeeper
    
  • 配置环境变量

    [root@qianfeng01 local]# vi /etc/profile .........省略...... export ZOOKEEPER_HOME=/usr/local/zookeeper export PATH=$ZOOKEEPER_HOME/bin:$PATH
    
  • 生效

    [root@qianfeng01 local]# source /etc/profile
    
  • 验证配置是否成功:使用tab键看看是否可以提示zookeeper相关脚本

  • 进入conf目录下,复制一个zoo.cfg文件

    cp zoo_sample.cfg  zoo.cfg
    
  • 修改zoo.cfg文件

    dataDir=/usr/local/zookeeper/zkData
    clientPort=2181
    server.1=qianfeng01:2888:3888
    server.2=qianfeng02:2888:3888
    server.3=qianfeng03:2888:3888
    
  • 如果dataDir属性指定的目录不存在,那么要创建出来

    mkdir /usr/local/zookeeper/zkData
    
  • 在zkData目录下创建myid写入相应数字

  • 将/etc/profile文件和zookeeper目录scp到其他机器上

  • 启动zookeeper集群,每台机器上都要运行一下命令

    zkServer.sh start
    zkServer.sh status
    

安装hbase

  • 上传解压更名

    [root@qphone01 software]# tar -zxvf hbase-1.2.1-bin.tar.gz -C /opt/apps/
    
  • 配置hbase-env.sh

    [root@qphone01 conf]# vi hbase-env.sh
    
    # The java implementation to use.  Java 1.7+ required.
    export JAVA_HOME=/opt/apps/jdk1.8.0_45
    
    # Tell HBase whether it should manage it‘s own instance of Zookeeper or not.
    export HBASE_MANAGES_ZK=true
    
  • hbase-site.xml

    <configuration>
            <property>
                    <name>hbase.cluster.distributed</name>
                    <value>true</value>
            </property>
            <property>
                    <name>hbase.rootdir</name>
                    <value>hdfs://qphone01:9000/hbase</value>
            </property>
            <property>
                    <name>hbase.zookeeper.quorum</name>
                    <value>qphone01,qphone02,qphone03</value>
            </property>
    </configuration>
    
  • regionservers

    qphone01
    qphone02
    qphone03
    
  • 将/etc/profile文件和hbase目录scp到其他机器上

  • 在qphone01的hbase的conf目录下创建backup-masters,写入qphone02做备用机器

    qphone02
    
  • 测试

    [root@qphone01 apps]# start-hbase.sh
    
    http://192.168.49.200:16010/master-status
    
  • jps查看进程

    • HMaster//必须的,表示hbase正常,因为配置了两个master一个是active状态一个是备用状态,所以在qianfeng01和qiangfeng02上各有一个hmaster
    • QuorumPeerMain//必须单独配置的Zookeeper集群,如果是内置的则为HQuorumPeer,表示zookeeper正常
  • 进入hbase的shell

    hbase shell
