关掉防火墙:

systemctl status firewalld.service  // 查看防火墙状态
systemctl stop firewalld.service    // 关掉防火墙
systemctl disable firewalld.service  // 关掉防火墙开机自启

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.

定时同步阿里云服务器时间:

yum -y install ntpdate
crontab -e 
*/1 * * * * /usr/sbin/ntpdate time1.aliyun.com

集群多机器之间设置免密登录:

ssh-keygen -t rsa 
// 三台机器在root用户下,执行以下命令将公钥拷贝到node01服务器上面去
ssh-copy-id  node01
// node01在root用户下,执行以下命令,将authorized_keys拷贝到node02与node03服务器
cd /root/.ssh/
scp authorized_keys  node02:$PWD
scp authorized_keys  node03:$PWD
