爱被打了一巴掌 2023-05-21 15:19 5阅读 0赞

### 首先声明，这篇博文相对比较长，大约需要10 min ###

## ##

### 1、阿里云官网登录，购买ecs云服务器     www.aliyun.com/ ###

如果你是新用户，需要注册，之后充值100

购买ecs服务器

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 5][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 6][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 8][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 9][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 10][]

我们可以看到公网和内网IP，将公网IP配置笔记本上的hosts文件，地址自己去找吧，这里不说了，我配置后的结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 11][]

这里顺便说下停止ecs服务器

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 12][]

### 2、配置远程连接 ###

我这里使用的远程连接工具是xshell,你们也可以使用crt或者MobaXterm工具

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 13][]

输入用户root和自己设置的密码就OK了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 14][]

然后以同样的方式进行后两台的连接

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 15][]

至此，3台机器已能够实现远程连接。

### 3、安装包准备 ###

> 1）JDK
> 
> 2）MySQL
> 
> 3）MySQL jdbc  jar包
> 
> 4）cm tar包   
> 
>   下载地址： [http://archive.cloudera.com/cm5/cm/5/][http_archive.cloudera.com_cm5_cm_5]
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 16][]
> 
> 5）parcel文件  3个
> 
>    下载地址：[http://archive.cloudera.com/cdh5/parcels/5.16.2/][http_archive.cloudera.com_cdh5_parcels_5.16.2]
> 
> ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 17][]

cm和parcel官网下载会非常慢，可以考虑使用迅雷

最终结果:

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 18][]

上传安装包到/root/cdh5.16.2，上传前增加滴1台机器的带宽

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 19][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 20][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2N6ejExNDE5Nzk1NzA_size_16_color_FFFFFF_t_70 21][]

然后上传，之后再将带宽修改为1M即可。

### 4、集群节点初始化 ###

1）hosts文件准备（**3台都需要配置**）

[root@mycluster001 ~]# cat /etc/hosts
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    
    172.16.170.107    mycluster001
    172.16.170.106    mycluster002
    172.16.170.105    mycluster003

2）防火墙关闭

自己的机房或者IDC托管的机器需要关闭，如果是云主机可以忽略关闭操作，但是云主机有web防火墙

systemctl stop firewalld
    systemctl disable firewalld
    iptables -F

3）关闭selinux,云主机是关闭状态的，如果不是disabled,可以使用下列命令进行关闭

sed -i 's#SELINUX=enable#SELINUX=disabled#g' /etc/selinux/config

4）时区/时钟同步(**如果机器为云主机，下面操作可忽略**)

[root@mycluster001 ~]# timedatectl
          Local time: Sat 2020-04-18 11:22:06 CST
      Universal time: Sat 2020-04-18 03:22:06 UTC
            RTC time: Sat 2020-04-18 11:22:06
           Time zone: Asia/Shanghai (CST, +0800)
         NTP enabled: yes
    NTP synchronized: yes
     RTC in local TZ: yes
          DST active: n/a

ntp选择第一台节点作为ntp的主节点，其他节点为从节点

yum -y install ntp（3台都需要操作）
    vi /etc/ntp.conf（只在第一台机器进行配置）
        #time
        server 0.asia.pool.ntp.org
        server 1.asia.pool.ntp.org
        server 2.asia.pool.ntp.org
        server 3.asia.pool.ntp.org
    
        #当外部时间不可用，可以使用当前本地硬件时间
        server 127.127.1.0 iburst local clock
    
        #允许哪些网段的机器来同步时间
        restrict 172.16.170.0 mask 255.255.255.0 nomodify notrap
    
    除了001机器，其他都关闭
    systemctl  stop ntpd
    systemctl disable ntpd
    [root@mycluster002 ~]# ntpdate mycluster001
    18 Apr 11:54:58 ntpdate[2394]: adjust time server 172.16.170.107 offset -0.004965 sec
    [root@mycluster003 ~]# ntpdate mycluster001
    18 Apr 11:55:23 ntpdate[2383]: adjust time server 172.16.170.107 offset 0.002791 sec

在002和003机器配置定时任务
    [root@mycluster002 ~]# crontab -e
    no crontab for root - using an empty one
    
    00 00 * * * ntpdate mycluster001

5）jdk tar包解压部署

>     （3台均需操作）
>     mkdir /usr/java/
>     tar -zxvf jdk-8u45-linux-x64.gz -C /usr/java/
>     cd /usr/java/
>     [root@mycluster001 java]# ll
>     total 4
>     drwxr-xr-x 8 10 143 4096 Apr 11  2015 jdk1.8.0_45
>     [root@mycluster001 java]# chown -R root:root jdk1.8.0_45/
>     [root@mycluster001 java]# ll
>     total 4
>     drwxr-xr-x 8 root root 4096 Apr 11  2015 jdk1.8.0_45
> 
> **坑： 上面解压后的jdk属主和属组改为root**

vi /etc/profile

![20200418121809898.png][]  
source /etc/profile

java -version    \#查看是否安装成功

6）离线部署MySQL

1.解压及创建目录
    [root@mycluster001 cdh5.16.2]# mv mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz.zip.001 /usr/local/
    [root@mycluster001 local]# tar xzvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz
    [root@mycluster001 local]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql
    [root@mycluster001 local]# mkdir mysql/arch mysql/data mysql/tmp
    
    
    2.创建my.cnf
    [root@mycluster001 local]# vi /etc/my.cnf
    [client]
    port            = 3306
    socket          = /usr/local/mysql/data/mysql.sock
    default-character-set=utf8mb4
    
    [mysqld]

    key_buffer_size = 256M
    sort_buffer_size = 256M
    read_buffer = 2M
    write_buffer = 2M
    
    3.创建用户组及用户
    [root@mycluster001 local]# groupadd -g 101 dba
    [root@mycluster001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
    useradd: warning: the home directory already exists.
    Not copying any file from skel directory into it.
    根据命令操作结果的提示：
    4.copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量
    [root@mycluster001 local]# cp /etc/skel/.* /usr/local/mysql  ###important
    
    5.配置环境变量
    [root@mycluster001 local]# vi mysql/.bash_profile
    
    # .bash_profile
    
    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
            . ~/.bashrc
    fi
    
    # User specific environment and startup programs
    export MYSQL_BASE=/usr/local/mysql
    export PATH=${MYSQL_BASE}/bin:$PATH
    
    
    unset USERNAME
    
    #stty erase ^H
    set umask to 022
    umask 022
    PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1
    
    ## end
    
    
    6.赋权限和用户组，切换用户mysqladmin，安装
    [root@mycluster001 local]# chown  mysqladmin:dba /etc/my.cnf 
    [root@mycluster001 local]# chmod  640 /etc/my.cnf  
    [root@mycluster001 local]# chown -R mysqladmin:dba /usr/local/mysql
    [root@mycluster001 local]# chmod -R 755 /usr/local/mysql 
    
    7.配置服务及开机自启动
    [root@mycluster001 local]# cd /usr/local/mysql
    [root@mycluster001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 
    [root@mycluster001 mysql]#  chmod +x /etc/rc.d/init.d/mysql
    [root@mycluster001 mysql]# chkconfig --add mysql
    [root@mycluster001 mysql]#  chkconfig --level 345 mysql on
    
    8.安装libaio及安装mysql的初始db
    [root@mycluster001 mysql]# yum -y install libaio
    [root@mycluster001 mysql]# sudo su - mysqladmin
    Last login: Sat Apr 18 12:51:42 CST 2020 on pts/0
    mycluster001:mysqladmin:/usr/local/mysql:>bin/mysqld \
    > --defaults-file=/etc/my.cnf \
    > --user=mysqladmin \
    > --basedir=/usr/local/mysql/ \
    > --datadir=/usr/local/mysql/data/ \
    > --initialize
    在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中
    （在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）
    
    9.查看临时密码
    mycluster001:mysqladmin:/usr/local/mysql:>cd data/
    mycluster001:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password 
    2020-04-18T05:01:49.024813Z 1 [Note] A temporary password is generated for root@localhost: (Oz5geZ31RaX
    
    10.启动
    mycluster001:mysqladmin:/usr/local/mysql/data:>/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
    
    11.登录及修改用户密码
    mycluster001:mysqladmin:/usr/local/mysql/data:>mysql -uroot -p'Oz5geZ31RaX'
    mysql> alter user root@localhost identified by '000000';
    Query OK, 0 rows affected (0.00 sec)
    mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '000000' ;
    Query OK, 0 rows affected, 1 warning (0.00 sec)
    mysql>  flush privileges;
    Query OK, 0 rows affected (0.00 sec)
    mysql> exit
    Bye
    
    12.重启
    mycluster001:mysqladmin:/usr/local/mysql/data:>service mysql restart
    Shutting down MySQL..2020-04-18T05:08:53.985098Z mysqld_safe mysqld from pid file /usr/local/mysql/data/hostname.pid ended

8)移动并重命名jdbc连接包

[root@mycluster001 cdh5.16.2]# ls
    CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel           manifest.json
