///离线安装/
ubuntu 16:
在有网的服务器上下载clickhouse安装包：
https://repo.yandex.ru/clickhouse/deb/stable/main/
clickhouse-client_19.4.3.11_all.deb
clickhouse-common-static_19.4.3.11_amd64.deb
clickhouse-server_19.4.3.11_all.deb
clickhouse-server-base_19.4.3.11_amd64.deb
clickhouse-server-common_19.4.3.11_all.deb
在有网的服务器上下载zk安装包：
https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
//用客户提供的服务器或者测试服务器，配置好离线环境的apt源
echo "172.31.135.108 ck001
172.31.135.110 ck002
172.31.135.109 ck003" > /etc/hosts
将ck和zk安装包上传到ck001, ck002, ck003的/opt/ckdeploy目录下
//1. 配置系统环境
//设置cpu频率模式
apt-get install cpufrequtils
cpufreq-set -c 0 -g performance
cat /proc/cpuinfo | grep MHz

apt-get install tzdata
echo "export TZ='Asia/Shanghai'" >> /etc/profile
echo "export LANG=zh_CN.UTF8" >> /etc/profile
source /etc/profile
swapoff -a
apt install -y openjdk-8-jdk
//2. 安装zookeeper
cd /opt/ckdeploy
tar -xzvf zookeeper-3.4.9.tar.gz
mv zookeeper-3.4.9 /opt/
cd /opt
ln -s zookeeper-3.4.9 zookeeper
cd zookeeper/conf

cd /opt/zookeeper
mkdir data
mkdir logs
//在ck001/ck002/ck003上分别执行以上操作，然后依次执行设置zk id的操作
//ck001
echo '1' > data/myid
//ck002
echo '2' > data/myid
//ck003
echo '3' > data/myid
//将三台服务器上zk都启动
/opt/zookeeper/bin/zkServer.sh start
//3. 安装clickhouse
//在三台服务器上分别用下面方法配置完clickhouse
cd /opt/ckdeploy
dpkg -i *.deb
cd /etc/clickhouse-server
vim config.xml
///config.xml中yandex节点下添加///
//
//注意!!!!!!!!config.xml中listen_host在三台服务器上分别配置为ck001/ck002/ck003
vim myconf.xml
///myconf.xml全部内容///
//
mkdir users.d
cd users.d
vim huxl.xml
///huxl.xml全部内容///
//
//分别在三台服务器上启动clickhouse服务
sudo service clickhouse-server start
//常用配置
//配置文件: /etc/clickhouse-server下
//ck服务器错误日志：/var/log/clickhouse-server/
///初始化3节点3分片2副本的集群/
