所有节点执行以下操作:
firewalld
或iptables
);selinux
;ntp
。所有节点设置/etc/hosts
cat << EOF >> /etc/hosts
# hadoop nodes
172.30.200.75 master
172.30.200.76 slave01
172.30.200.77 slave02
172.30.200.78 slave03
EOF
在所有节点生成秘钥
ssh-keygen -t rsa
在master节点生成authorized_keys
文件
cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
在master节点执行,将集群每个节点的公钥id_rsa.pub
放入master节点的authorized_keys
文件中
for i in {1..3}; do ssh root@slave0$i cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys; done
authorized_keys
文件放置到集群每个节点的/root/.ssh/
目录,依然命名位authorized_keys
公钥检查
,可通过在/etc/ssh/ssh_config
文件中设置StrictHostKeyChecking no
绕过,或使用-o
参数跳过。for i in {1..3}; do scp /root/.ssh/authorized_keys root@slave0$i:/root/.ssh/authorized_keys; done
所有节点都需要安装JDK。
安装JDK
cd /usr/local/src
tar -zxvf jdk-8u181-linux-x64.tar.gz
mkdir -p /usr/java
mv jdk1.8.0_181/ /usr/java/

目录
tar -zxvf /usr/local/src/cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz -C /opt/cloudera-manager/
在所有slave节点修改/opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/config.ini

useradd --system --home=/opt/cloudera-manager/cm-5.16.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
在所有节点为/opt/cloudera-manager

chown cloudera-scm:cloudera-scm /opt/cloudera-manager/cm-5.16.1/share/cmf/lib/mysql-connector-java-8.0.13.jar
在master节点重启MySQL服务
service mysqld restart

设置为最大值10
。
swappiness
值控制操作系统尝试交换内存的积极;swappiness=0
:表示最大限度使用物理内存,之后才是swap空间;swappiness=100
:表示积极使用swap分区,并且把内存上的数据及时搬迁到swap空间;swappiness
。临时调整:
