一、简介
二、生产集群搭建
准备
- Zookeeper集群
- Linux服务器四台(以四台为列)
创建用户组和用户
groupadd clickhouse ---创建用户组
useradd -m -d /home/clickhouse -g clickhouse clickhouse ---创建用户
passwd clickhouse ---修改密码
下载
准备好ClickHouse安装包，官网下载地址（选择需要下载的版本）
- clickhouse-common-static-$LATEST_VERSION.tgz
- clickhouse-common-static-dbg-$LATEST_VERSION.tgz
- clickhouse-server-$LATEST_VERSION.tgz
- clickhouse-client-$LATEST_VERSION.tgz
解压、安装(注意切换用户clickhouse)
tar -xzvf clickhouse-common-static-$LATEST_VERSION.tgz
sudo clickhouse-common-static-$LATEST_VERSION/install/doinst.sh
tar -xzvf clickhouse-common-static-dbg-$LATEST_VERSION.tgz
sudo clickhouse-common-static-dbg-$LATEST_VERSION/install/doinst.sh
tar -xzvf clickhouse-server-$LATEST_VERSION.tgz
sudo clickhouse-server-$LATEST_VERSION/install/doinst.sh
#启动命令
sudo systemctl start clickhouse-server 或 sudo /etc/init.d/clickhouse-server start
#安装clickhouse-client,在其中一台机器安装即可,用于命令连接clickhouse-server
tar -xzvf clickhouse-client-$LATEST_VERSION.tgz
sudo clickhouse-client-$LATEST_VERSION/install/doinst.sh
修改配置
安装成功后，在/etc/clickhouse-server/ 目录下生成配置文件config.xml及user.xml、自定义配置目录config.d及users.d，推荐在config.d及users.d下新建配置文件，然后在config.xml及user.xml中引入config.d及users.d下的配置文件。
- 修改config.xml
mkdir /opt/clickhouse_data #新建ClickHouse数据目录
chown -R clickhouse:clickhouse /opt/clickhouse_data #注意修改目录权限
sudo vim /etc/clickhouse-server/config.xml
<level>trace</level>
<log>/opt/clickhouse_data/log/clickhouse-server/clickhouse-server.log</log>
<errorlog>/opt/clickhouse_data/log/clickhouse-server/clickhouse-server.err.log</errorlog>
<path>/opt/clickhouse_data/clickhouse/</path>
<tmp_path>/opt/clickhouse_data/clickhouse/tmp/</tmp_path>
<user_files_path>/opt/clickhouse_data/clickhouse/user_files/</user_files_path>
<include_from>/etc/clickhouse-server/config.d/metrika.xml</include_from> <!--添加该参数-->
- 新建/etc/clickhouse-server/config.d/metrika.xml
vim /etc/clickhouse-server/config.d/metrika.xml
