linux hadoop-ha 三台机器 安装
0.规定
IP hostname role 10.156.50.35 master1 主节点 10.156.50.36 master2 备份主节点 10.156.50.37 slaver1 从节点
1. 创建 zkkafka 用户
useradd zkkafka passwd zkkafka zkkafka
2.修改 sudoers
chmod -R 777 /etc/sudoers ## Allow root to run any commands anywhere root ALL=(ALL) ALL zkkafka ALL=(ALL) ALL ## Allows members of the 'sys' group to run networking, software, ## service management apps and more. # %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS ## Allows people in group wheel to run all commands %wheel ALL=(ALL) ALL %wheel ALL=(ALL) NOPASSWD: ALL ## Same thing without a password chmod -R 440 /etc/sudoers sudo scp /etc/sudoers root@10.156.50.36:/etc/ sudo scp /etc/sudoers root@10.156.50.37:/etc/
3.修改 hosts
[zkkafka@yanfabu2-35 ~]$ sudo cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.156.50.35 yanfabu2-35.base.app.dev.yf zk1 hadoop1 master1 master 10.156.50.36 yanfabu2-36.base.app.dev.yf zk2 hadoop2 master2 10.156.50.37 yanfabu2-37.base.app.dev.yf zk3 hadoop3 slaver1 sudo scp /etc/hosts root@10.156.50.36:/etc/ sudo scp /etc/hosts root@10.156.50.37:/etc/
4.修改主机交换空间 集群的selinux
vim /etc/sysctl.conf
vm.swappiness = 0
setenforce 0
vi /etc/selinux/config
SELINUX=disabled
sudo scp /etc/sysctl.conf root@10.156.50.36:/etc/
sudo scp /etc/sysctl.conf root@10.156.50.37:/etc/
5.关闭防火强
service iptables status service iptables stop
6.生成免密登陆 第一次ssh需要密码
master slave
ssh-keygen -t rsa 空格 空格
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
slave
ssh-copy-id -i hadoop1
ssh-copy-id -i hadoop1
master
chmod 600 authorized_keys
scp ~/.ssh/authorized_keys zkkafka@10.156.50.36:~/.ssh/
scp ~/.ssh/authorized_keys zkkafka@10.156.50.37:~/.ssh/

7.4 修改环境变量
vi ~/.bash_profile export HADOOP_HOME=/home/zkkafka/hadoop export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$PATH source ~/.bash_profile
7.5 需要修改文件
/home/zkkafka/hadoop/etc/hadoop/hadoop-env.sh /home/zkkafka/hadoop/etc/hadoop/yarn-env.sh /home/zkkafka/hadoop/etc/hadoop/core-site.xml /home/zkkafka/hadoop/etc/hadoop/hdfs-site.xml /home/zkkafka/hadoop/etc/hadoop/mapred-site.xml /home/zkkafka/hadoop/etc/hadoop/yarn-site.xml
