修改主机名

hostnamectl set-hostname bigdata-cdh01.kfk.com

修改本机DNS /etc/host

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.52.130 bigdata-cdh01.kfk.com bigdata-cdh01

关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service （开机不启动）
systemctl status firewalld.service

禁用selinux cat /etc/sysconfig/selinux

SELINUX=disabled

临时关闭selinux

getenforce
setenforce 0
getenforce

禁用ipv6

echo "            " >> /etc/modprobe.d/dist.conf
echo "alias net-pf-10 off" >> /etc/modprobe.d/dist.conf
echo "alias ipv6 off" >> /etc/modprobe.d/dist.conf

卸载JDK

rpm -qa | grep java
rpm -e --nodeps xxx

设置文件打开数目和用户最大进程数
文件打开数目

ulimit -a

用户最大进程数

ulimit -u

设置 /etc/security/limits.conf

*    soft   nofile 32768
*    hard   nofile 1048576
*    soft   nproc  65536
*    hard   nporc  unlimited
*    soft   memlock unlimited
*    hard   memlock unlimited

ssh互信

ssh-keygen -t rsa
touch authorized_keys
chmod 600 authorized_keys
cat id_rsa.pub > authorized_keys
ssh-copy-id -i id_rsa.pub root@192.168.52.130

使用ntp进行时间同步
主节点

driftfile /var/lib/ntp/drift
restrict 192.168.52.130 nomodify notrap nopeer noquery    
restrict 127.0.0.1
restrict ::1
restrict 192.168.52.2 mask 255.255.255.0 nomodify notrap
server 127.127.1.0
Fudge  127.127.1.0 stratum 10
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor

从节点，其他节点同理

driftfile /var/lib/ntp/drift
restrict 192.168.52.131 nomodify notrap nopeer noquery    
restrict 127.0.0.1
restrict ::1
restrict 192.168.52.2 mask 255.255.255.0 nomodify notrap
server 192.168.52.130
Fudge  192.168.52.130 stratum 10
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor

先关闭ntpd

ntpdate 192.168.52.130
service ntpd restart
systemctl enable ntpd

ntpq -p 检查是否同步，有*表示已经同步

关闭透明大页和交换内存

    echo never > /sys/kernel/mm/transparent_hugepage/defrag  
    echo never > /sys/kernel/mm/transparent_hugepage/enabled   
    echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local  
    echo "echo never > /sys/kernel/mm/transparent_hugepage/defrag" >> /etc/rc.local  
    chmod +x /etc/rc.d/rc.local  
    echo "vm.swappiness=1" >> /etc/sysctl.conf  
    sysctl -p    //使配置生效
