5 启动

5.1 如果没有service，可以运行如下命令在后台启动服务

# 查看命令
[root@ecs-65685 ~]# clickhouse-server --help
usage:
clickhouse-server [OPTION] [-- [ARG]...]
positional arguments can be used to rewrite config.xml properties, for
example, --http_port=8010

-h, --help                        show help and exit
-V, --version                     show version and exit
-C<file>, --config-file=<file>    load configuration from a given file
-L<file>, --log-file=<file>       use given log file
-E<file>, --errorlog-file=<file>  use given log file for errors only
-P<file>, --pid-file=<file>       use given pidfile
--daemon                          Run application as a daemon.
--umask=mask                      Set the daemon"s umask (octal, e.g. 027).
--pidfile=path                    Write the process ID of the application to given file.

# 启动
sudo /etc/init.d/clickhouse-server start

# 停止
sudo /etc/init.d/clickhouse-server stop

日志文件将输出在 /var/log/clickhouse-server 文件夹。

如果服务器没有启动，检查 /etc/clickhouse-server/config.xml 中的配置。

5.2 手动从控制台启动服务器

[root@ecs-65685 ~]# clickhouse-server --config-file=/etc/clickhouse-server/config.xml

在这种情况下，日志将被打印到控制台，这在开发过程中很方便。

如果配置文件在当前目录中，则不需要指定——config-file参数。默认情况下，它的路径为./config.xml。

5.3 root 用户启动失败

检查 ClickHouse 相关的用户目录，会发现用户和组都是ClickHouse

ll /etc/clickhouse-server
ll /var/log/clickhouse-server
ll /var/lib/clickhouse

5.4 clickhouse 用户启动

用 clickhouse 用户来启动 clickhouse server

sudo -u "clickhouse" /usr/bin/clickhouse-server --config-file /etc/clickhouse-server/config.xml --pid-file /var/run/clickhouse-server/clickhouse-server.pid

# 查看进程
[root@ecs-65685 ~]# ps -ef |grep clickhouse
clickho+    1803       1  0 20:17 ?        00:00:00 clickhouse-watchdog        --config=/etc/clickhouse-server/config.xml --pid-file=/run/clickhouse-server/clickhouse-server.pid

root        3079    2949  0 20:19 pts/0    00:00:00 grep --color=auto clickhouse

6 root 用户启动

将 ClickHouse 相关的用户目录全部设置成 root

chown -R root:root /var/lib/clickhouse /var/log/clickhouse-server /etc/clickhouse-server /etc/clickhouse-client

6.1 使用root用户命令启动

[root@ecs-65685 ~]# sudo /etc/init.d/clickhouse-server start
 chown -R clickhouse: "/var/run/clickhouse-server/"
Will run sudo -u "clickhouse" /usr/bin/clickhouse-server --config-file /etc/clickhouse-server/config.xml --pid-file /var/run/clickhouse-server/clickhouse-server.pid --daemon
Waiting for server to start
Waiting for server to start
Server started

7 命令行客户端

ClickHouse 提供了一个原生命令行客户端 clickhouse-client 客户端支持命令行。

安装部署后，系统默认会安装 clickhouse-client(同时它属于clickhouse-client安装包中)。

# 没有密码可不加 --password
[root@ecs-65685 ~]# clickhouse-client --password
ClickHouse client version 22.10.2.11 (official build).
Password for user (default):
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 22.10.2 revision 54460.

Warnings:
 * Linux transparent hugepages are set to "always". Check /sys/kernel/mm/transparent_hugepage/enabled
 * Maximum number of threads is lower than 30000. There could be problems with handling a lot of simultaneous queries.

ecs-65685 :)

不同的客户端和服务器版本彼此兼容，但是一些特性可能在旧客户机中不可用。建议使用与服务器应用相同版本的客户端。

默认情况下，使用default用户并不携带密码连接到localhost:9000。

还可以使用--host参数连接到指定服务器。终端必须使用 UTF-8 编码。

三、允许远程访问

1 ClickHouse 默认不允许远程访问，需要修改配置文件

2 重启 ClickHouse

clickhouse restart

3 使用浏览器验证一下，服务器 IP:8123

四、使用DBeaver连接 ClickHouse

第一次链接要安装相应驱动，填写对应IP和端口，用户名，密码[没有设置可以不填]。

测试连接

五、防火墙

# 关闭防火墙
systemctl stop firewalld

firewall-cmd --zone=public --add-port=8123/tcp --permanent

# 配置立即生效
firewall-cmd --reload

# 重启防火墙生效
systemctl restart firewalld

云主机配置安全组，在入方向规则，允许8123放行。
