组件安装
- 安装 expect 命令,实现脚本交互
#所有节点
yum install expect -y
- rhel 7 默认没有pstree命令,使用以下命令进行安装
#所有节点
yum install psmisc -y
- rhel 7 如果为最小安装时,全报客户端部署错误,此时一般是由于缺程序引起的,常见的是缺perl
#所有节点
yum install perl -y
- hue 需要使用到 httpd
#所有节点
yum install httpd mod_ssl -y
- kudu 需要以下组件
#所有节点
yum install gcc python-devel -y
yum install cyrus-sasl* -y
调整host文件
#所有节点
cat >> /etc/hosts <<EOF
192.168.88.220 worker-1
192.168.88.221 worker-2
192.168.88.222 worker-3

关闭selinux
#所有节点
grep ^SELINUX= /etc/selinux/config
sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
getenforce
关闭iptables
#所有节点
systemctl disable firewalld
systemctl stop firewalld
ssh互信
#所有节点
ssh-keygen -t rsa
- 在每台机器械上执行
#逐条执行
ssh-copy-id root@worker-1
ssh-copy-id root@worker-2
ssh-copy-id root@worker-3
- 主节点执行
scp ~/.ssh/authorized_keys root@worker-1:/root/.ssh/
scp ~/.ssh/authorized_keys root@worker-2:/root/.ssh/
scp ~/.ssh/authorized_keys root@worker-3:/root/.ssh/
验证ssh效果
- 调整系统使用swap的策略
调整系统使用swap的策略,设置为1,即最大限度使用物理内存,少使用swap空间
#所有节点执行
#检查当前设置值
sysctl -a | grep vm.swappiness
echo 1 > /proc/sys/vm/swappiness
sysctl -a | grep vm.swappiness
#更改默认配置
cat >> /etc/sysctl.conf <<EOF
vm.swappiness=1

#设置立即生效
sysctl vm.swappiness=1
#设置下次启动生效
cat >> /etc/rc.d/rc.local <<EOF

#从节点执行,且只能填写ip不能使用hostname,对应的ip为主节点的ip地址
mv -n /etc/ntp.conf /etc/ntp.conf.bak
cat > /etc/ntp.conf << EOF
server 192.168.88.220 iburst
EOF
#禁用chronyd服务,RHEL 7中默认启用了,这会导致ntpd服务无法开机启动
systemctl disable chronyd
