由于我们的操作系统为CentOS7,需要下载以下文件:

系统准备
1. 准备虚拟机(根据自己的系统资源分配虚拟机资源)
操作系统 | cpu | 内存 | 硬盘 | hostname | ip | 角色 |
---|---|---|---|---|---|---|
CentOS 7 (64 位) | 2vCpu | 16GiB | 800GiB | manager | 192.168.124.100 | clouder-manager |
CentOS 7 (64 位) | 12vCpu | 32GiB | 800GiB | node1 | 192.168.124.101 | |
CentOS 7 (64 位) | 12vCpu | 32GiB | 800GiB | node2 | 192.168.124.102 | |
CentOS 7 (64 位) | 12vCpu | 32GiB | 800GiB | node3 | 192.168.124.103 |
2. 静态IP设置(每个节点)
网络配置vim /etc/sysconfig/network-scripts/ifcfg-ens192
service network restart 重启网络生效
yum install -y net-tools ifconfig查看设置
3. 编辑/etc/hosts文件(每个节点)
vim /etc/hosts
192.168.124.100 manager
192.168.124.101 node1
192.168.124.102 node2
192.168.124.103 node3
4. 关闭防火墙、禁止防火墙开机自启(每个节点)
- systemctl stop firewalld 关闭防火墙
- systemctl disable firewalld 禁止防火墙开机自启
-
vim /etc/selinux/config —> SELINUX=disabled (修改)
防火墙
5. ssh无密码登录
- manager节点执行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
- cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 将公钥追加到authorized_keys
- chmod 600 ~/.ssh/authorized_keys 修改权限
- 将~/.ssh从当前节点分发到其他各个节点。如:scp -r ~/.ssh/ root@node1:~/.ssh/
- ssh 各个节点互相登陆
6. 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
-
ntp主机配置 vim /etc/ntp.conf
-
manager节点
ntp -
其余节点
-
重新启动 ntp 服务:service ntpd restart
-
设置开机自启:systemctl enable ntpd.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):
success success2
7. 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
-
cd /usr/lib/tuned/
-
grep “vm.swappiness” * -R 查询出后依次修改
ori修改完确认:
success -
参考:sysctl修改内核参数 重启不生效https://blog.csdn.net/ygtlovezf/article/details/79014299
8. 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
toumingye -
给与可执行权限:chmod +x /etc/rc.d/rc.local
9. JDK安装(所有节点)
- rpm -qa | grep java # 查询已安装的java
- yum remove java* # 卸载
- rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm
- vi /etc/profile 末尾添加
# java
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
export CLASSPATH=.:$CLASSPTAH:$JAVA_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin
- source /etc/profile
- java -version验证
10. 创建/usr/share/java目录,将mysql-jdbc包放过去(所有节点)
- mkdir -p /usr/share/java
- mv /opt/mysql-j/mysql-connector-java-5.1.34.jar /usr/share/java/
- mysql-connector-java-5.1.34.jar 一定要命名为mysql-connector-java.jar
11. 为保证防火墙、虚拟机参数修改后生效,各节点机器需要重启 reboot
12. Mysql安装
-
卸载mariadb:rpm -qa|grep mariadb
-
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
-
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
-
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 如果不能登陆
-
设置免密登录并重启mysql服务
-
vi /etc/my.cnf
mysql -
systemctl restart mysqld
-
登录
$>mysql -u root
mysql>use mysql;
mysql>update user set authentication_string = password(‘123456’), password_expired = ‘N’, password_last_changed = now() where user = ‘root’;
mysql>exit; -
创建库(后续安装服务等使用)
CREATE DATABASE cmserver DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON cmserver.* TO 'cmserveruser'@'%' IDENTIFIED BY 'Yyf5211314!';
CREATE DATABASE metastore DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON metastore.* TO 'hiveuser'@'%' IDENTIFIED BY 'Yyf5211314!';
CREATE DATABASE amon DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON amon.* TO 'amonuser'@'%' IDENTIFIED BY 'Yyf5211314!';
CREATE DATABASE rman DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON rman.* TO 'rmanuser'@'%' IDENTIFIED BY 'Yyf5211314!';
CREATE DATABASE oozie DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON oozie.* TO 'oozieuser'@'%' IDENTIFIED BY 'Yyf5211314!';
CREATE DATABASE hue DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
GRANT ALL ON hue.* TO 'hueuser'@'%' IDENTIFIED BY 'Yyf5211314!';
13. 安装Httpd服务(manager)
- yum install httpd
- service httpd start
- systemctl enable httpd.service 设置httpd服务开机自启
14. 防止出现莫名错误,事先安装以下插件(所有节点)
- yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server --skip-broken --nogpgcheck
15. 配置Cloudera Manager包yum源(manager节点)
-
mkdir -p /var/www/html/cloudera-repos/
-
将下载的cm包文件移到此目录下:
-
mv cm6 /var/www/html/cloudera-repos/
-
cd /var/www/html/cloudera-repos/cm6/
-
创建repodata: createrepo .
cm6
-
vim /etc/yum.repos.d/cloudera-manager.repo
pro -
yum clean all
-
yum makecache
16.导入GPG key(如果没有这步操作,很可能cloudera服务安装失败)manager节点
rpm --import https://archive.cloudera.com/cm6/6.2.0/redhat7/yum/RPM-GPG-KEY-cloudera
17. 安装 Cloudera Manager(manager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-6.2.0-1.cdh6.2.0.p0.967373-el7.parcel | awk ‘{ print $1 }’ > CDH-6.2.0-1.cdh6.2.0.p0.967373-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
- 静候几分钟,打开http://manager:7180
