1，确定防火墙处于关闭状态
2，CentOS取消打开文件数限制
vim /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 * soft nproc 131072 * hard nproc 131072
vim /etc/security/limits.d/20-nproc.conf * soft nofile 65536 * hard nofile 65536 * soft nproc 131072 * hard nproc 131072
3，将上述配置文件同步到其他要安装ClickHouse的节点
scp /etc/security/limits.d/20-nproc.conf node2:/etc/security/limits.d/20-nproc.conf scp /etc/security/limits.d/20-nproc.conf node3:/etc/security/limits.d/20-nproc.conf
4，安装依赖
yum install -y libtool yum install -y *unixODBC*
5，Centos取消selinux
vim /etc/selinux/config SELINUX=disabled
分发到其他结点：
scp /etc/selinux/config node2:/etc/selinux/config scp /etc/selinux/config node3:/etc/selinux/config

把
5，分发配置文件到其他服务器
