环境准备

#创建clickhouse用户与用户组
sudo groupadd clickhouse
sudo useradd -m clickhouse -g clickhouse
#密码为clickhouse
sudo passwd clickhouse

#赋予权限
chmod -R 777 /opt/comm_app

#配置使用sudo命令的用户
vim /etc/sudoers
clickhouse    ALL=(ALL:ALL) ALL

配置调整

1.配置开放外网访问

vim /etc/clickhouse-server/config.d/listen.xml
<clickhouse>
    <listen_host>0.0.0.0</listen_host>
</clickhouse>


2.配置修改登录密码

vim /etc/clickhouse-server/users.d/default-password.xml
<clickhouse>
    <users>
        <default>
            <password>EqcT3KF4kQ?v</password>
        </default>
    </users>
</clickhouse
