操作系统配置

虚拟机建议配置mastet节点2核8G内存50G硬盘,其它节点2核4G内存40G硬盘(硬盘建议SSD)

 

red had 7.2 ip配置 (虚拟机nat模式)

参考:nat联网设置:https://blog.csdn.net/ping0817/article/details/45867547

vi /etc/sysconfig/network-scripts/ifcfg-eno16777736

TYPE=Ethernet

BOOTPROTO=static

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

NAME=eno16777736

DEVICE=eno16777736

ONBOOT=yes

IPADDR=32.188.35.51

GATEWAY=32.188.35.2

NETMASK=255.255.255.0

DNS1=32.188.35.2

 

network配置(所有节点)

vim /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=cdh001

配置hosts(所有节点)

vim /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

32.188.35.51 cdh001

32.188.35.52 cdh002

32.188.35.53 cdh003

关闭防火墙和selinux(所有节点)

systemctl stop firewalld

systemctl disable firewalld

vim /etc/selinux/config(修改下列)

SELINUX=disabled

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

ssh无密码登录

 

1)在每一个节点根目录下执行以下操作:

ssh-keygen -t rsa

一路回车到结束,在/root/.ssh/下面会生成一个公钥文件

id_rsa.pub

2)将公钥追加到authorized_keys,在每个节点执行该操作:

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

3)修改权限,在每个节点执行

chmod 600 ~/.ssh/authorized_keys

4)将id_rsa.pub从当前节点分发到其他各个节点

5)每个节点将远程复制过来的公钥追加到authorized_keys里面(即每个节点的authorized_keys存储所有节点的公匙)

6)各节点执行ssh root@hostname 测试是否可以实现免密登录

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

配置本地os的yum源(节点1操作)

mkdir /mnt/rhel7.2

mount -o loop /opt/os/rhel-server-7.2-x86_64-dvd.iso /mnt/rhel7.2

【重启后需重新mount,

可以修改/etc/fstab文件开机自动mount: vi /etc/fstab 添加

/opt/os/rhel-server-7.2-x86_64-dvd.iso /mnt/rhel7.2 iso9660 defaults,loop 0 0

mount –a #测试挂载】

vi /etc/yum.repos.d/local.repo

[iso]

name= rhel-server-7.2-x86_64-dvd.iso

baseurl=file:///mnt/rhel7.2

gpgcheck=0

enabled=1

yum clean all

yum makecache

 

 

安装Httpd服务(节点1)

yum install httpd

service httpd start

设置httpd服务开机自启

systemctl enable httpd.service

 

mkdir /var/www/html/iso/

ln -s /mnt/rhel7.2 /var/www/html/iso/

 

配置其他节点os的yum源(其他节点操作)

vi /etc/yum.repos.d/local.repo

[http_iso]

name=iso_7.2

baseurl=http://cdh001/iso/rhel7.2

gpgcheck=0

enabled=1

 

yum clean all

yum makecache

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

配置NTP服务(所有节点)

 

修改时区(改为中国标准时区)

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

 

 

安装ntp

yum -y install ntp

 

vi /etc/ntp.conf

ntp主机配置

restrict 32.188.35.0 mask 255.255.255.240 nomodify notrap

server 127.127.1.0 # local clock

fudge 127.127.1.0 stratum 10

 

以下内容注释掉

#server 0.rhel.pool.ntp.org iburst

#server 1.rhel.pool.ntp.org iburst

#server 2.rhel.pool.ntp.org iburst

#server 3.rhel.pool.ntp.org iburst

 

 

 

其它节点配置

server cdh001

fudge cdh001 stratum 10

重新启动 ntp 服务:

service ntpd restart

设置开机自启systemctl enable ntpd.service

rhel7.x中默认安装了chrony,关闭chronyd 的开机自启systemctl disable chronyd.service

ntpdc -c loopinfo #查看与时间同步服务器的时间偏差

ntpq -p #查看当前同步的时间服务器

ntpstat #查看状态

 

配置成功状态(服务开启后前面出现*说明成功):

 

参考:ntp相关配置:https://blog.csdn.net/wisdom_c_1010/article/details/56830837

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

修改Linux swappiness参数(所有节点)

 

【为了避免服务器使用swap功能而影响服务器性能,一般都会把vm.swappiness修改为0(cloudera建议10以下)

echo 0 > /proc/sys/vm/swappiness

这样操作重启机器还是还原

修改配置文件,开机自动设置参数

编辑vim /etc/sysctl.conf

在最后添加vm.swappiness=0】

 

上述方法rhel6有效,rhel7.2中

tuned服务会动态调整系统参数

查找tuned中配置,直接修改配置

[root@cdh01 ~]# cd /usr/lib/tuned/

[root@cdh01 tuned]# grep "vm.swappiness" * -R

查询出后依次修改

修改完确认

参考:sysctl修改内核参数 重启不生效https://blog.csdn.net/ygtlovezf/article/details/79014299

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

禁用透明页(所有节点)

设置方法

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

给与可执行权限:

chmod +x /etc/rc.d/rc.local

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

JDK安装(所有节点)

卸载原有java

rpm -qa | grep java # 查询已安装的java

yum remove java* # 卸载

安装JDK以及配置环境变量

rpm -ivh /opt/JDK/jdk-8u144-linux-x64.rpm

 

vi /etc/profile

# 末尾添加

export JAVA_HOME=/usr/java/jdk1.8.0_144

export CLASSPATH=.:$CLASSPTAH:$JAVA_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin

 

source /etc/profile

 

创建/usr/share/java目录,将mysql-jdbc包放过去

mkdir -p /usr/share/java

mv /opt/mysql-j/mysql-connector-java.jar /usr/share/java/

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

MYSQL安装(主节点)

1卸载mariadb

[root@cdh001 opt]# rpm -qa|grep mariadb

mariadb-libs-5.5.44-2.el7.x86_64

[root@cdh001 opt]# rpm -e mariadb-libs-5.5.44-2.el7.x86_64

error: Failed dependencies:

libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

[root@cdh001 opt]# rpm -e postfix-2:2.10.1-6.el7.x86_64

[root@cdh001 opt]# rpm -e mariadb-libs-5.5.44-2.el7.x86_64

2 MYSQL安装

cd /opt/mysql/

tar -xvf ./mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

 

rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm

3 MYSQL配置

mysqld --initialize --user=mysql # 初始化mysql使mysql目录的拥有者为mysql用户

cat /var/log/mysqld.log # 最后一行将会有随机生成的密码

systemctl start mysqld.service # 设置mysql服务自启

mysql -uroot –p

# 输入临时密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root'; # 修改密码

 

4 创建库(后续安装服务等使用)

CREATE DATABASE cmserver DEFAULT CHARACTER SET utf8;

GRANT ALL on cmserver.* TO 'cmserveruser'@'%' IDENTIFIED BY 'password';

 

CREATE DATABASE metastore DEFAULT CHARACTER SET utf8;

GRANT ALL on metastore.* TO 'hiveuser'@'%' IDENTIFIED BY 'password';

 

CREATE DATABASE amon DEFAULT CHARACTER SET utf8;

GRANT ALL on amon.* TO 'amonuser'@'%' IDENTIFIED BY 'password';

 

CREATE DATABASE rman DEFAULT CHARACTER SET utf8;

GRANT ALL on rman.* TO 'rmanuser'@'%' IDENTIFIED BY 'password';

 

CREATE DATABASE oozie DEFAULT CHARACTER SET utf8;

GRANT ALL on oozie.* TO 'oozieuser'@'%' IDENTIFIED BY 'password';

 

CREATE DATABASE hue DEFAULT CHARACTER SET utf8;

GRANT ALL on hue.* TO 'hueuser'@'%' IDENTIFIED BY 'password';

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

配置Cloudera Manager包yum源(主节点)

mkdir -p /var/www/html/cloudera-repos

将下载的cm包文件移到此目录下

创建repodata

[root@cdh001 cm6]# createrepo .

创建.repo

[root@cdh001 cm6]# vim /etc/yum.repos.d/cloudera-manager.repo

[cloudera-manager]

name = Cloudera Manager, Version

baseurl = http://cdh001/cloudera-repos/cm6/

gpgcheck = 1

~

yum clean all

yum makecache

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 

安装 Cloudera Manager(主节点)

sudo yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

#安装完CM后/opt/ 下会出现cloudera目录

mv /opt/parcels/* /opt/cloudera/parcel-repo # 将parcel包移动到指定位置

在/opt/cloudera/parcel-repo执行以下命令:

sha1sum CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel | awk '{ print $1 }' > CDH-6.0.0-1.cdh6.0.0.p0.537114-el7.parcel.sha

 

# 执行初始化脚本

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql cmserver cmserveruser password

 

# 打开server服务

service cloudera-scm-server start

top命令查看cpu占用大幅升高,cpu使用率下降后说明服务已起

 

查看CM页面是否已可以打开

http://32.188.35.51:7180

 

 

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

集群安装配置

 

 

 

 

按Option1说明配置auto-tls

JAVA_HOME=/usr/java/jdk1.8.0_144 /opt/cloudera/cm-agent/bin/certmanager --location /opt/cloudera/CMCA setup --configure-services

service cloudera-scm-server restart

重启后打开7180自动跳转至7183

 

 

 

 

所有节点JDK已安装,这里不勾选

Agents安装

parcels分发

 

检测

 

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

集群安装配置(可后续依需求单个服务安装,此处选择Essentials安装)

 

选择服务安装节点(namenode与secondaryNameNode尽量不要放在一个节点,我这里当时比较随意没注意,后续可以迁移)

填入之前创建的库名用户密码,测试连接success后continue

各项配置

 

初次运行

 

完成

 

 

 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

安装过程中可能遇到的问题:

需要使用sha1sum校验parcel包生成校验文件,不然parcel包不识别

allkeys.asc 文件忘记下载,安装Agents会报错
