在Ubuntu20.04安装单节点ClickHouse22.8.4并解决DB::NetException: Connection refused (192.168.88.22:9000). (NETWORK_ERROR)导致无法远程访问的问题

前言

参照ClickHouse官网提供的安装文档:https://clickhouse.com/docs/zh/getting-started/install

虚拟机准备

轻车熟路,参照:https://lizhiyong.blog.csdn.net/article/details/126236516

基础网络

静态IP:192.168.88.22

子网掩码:255.255.255.0

网关:192.168.88.2

DNS:8.8.8.8

禁用IPV6

更换源

不一定每次都指定阿里云。。。自动选个速度最快的即可。

安装必要命令

sudo apt-get install net-tools
sudo apt-get install openssh-server
sudo apt-get install openssh-client
apt install vim

之后可以使用MobaXterm连接:

zhiyong@zhiyong-ck1:~$ hostname

指令集检查

根据官方文档介绍:

ClickHouse可以在任何具有x86_64,AArch64或PowerPC64LE CPU架构的Linux,FreeBSD或Mac OS X上运行。

官方预构建的二进制文件通常针对x86_64进行编译,并利用SSE 4.2指令集,因此,除非另有说明,支持它的CPU使用将成为额外的系统需求。下面是检查当前CPU是否支持SSE 4.2的命令:

$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"

要在不支持SSE 4.2AArch64PowerPC64LE架构的处理器上运行ClickHouse,您应该通过适当的配置调整从源代码构建ClickHouse

执行:

zhiyong@zhiyong-ck1:~$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
SSE 4.2 supported

笔者的Intel Xeon 2693V3双路显然支持该指令集,可以使用官方编译好的包继续安装。

安装ClickHouse

官方离线安装包下载地址:https://packages.clickhouse.com/deb/pool/stable/

大版本号目前最新是22.8。自己玩玩,当然是最新版。。。

安装包列表:

  • clickhouse-common-static — ClickHouse编译的二进制文件。
  • clickhouse-server — 创建clickhouse-server软连接,并安装默认配置服务
  • clickhouse-client — 创建clickhouse-client客户端工具软连接,并安装客户端配置文件。
  • clickhouse-common-static-dbg — 带有调试信息的ClickHouse二进制文件。

使用Deb安装包

由于虚拟机是Ubuntu,当然应该是用Deb的apt安装包。如果一定要使用RPM的yum源,自己想办法实现,坑不是一般的大。。。dev没什么安全策略,直接在线下载安装就行:

sudo apt-get install -y apt-transport-https ca-certificates dirmngr
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 8919F6BD2B48D754

echo "deb https://packages.clickhouse.com/deb stable main" | sudo tee \\
    /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

sudo apt-get install -y clickhouse-server clickhouse-client

sudo service clickhouse-server start
clickhouse-client # or "clickhouse-client --password" if you've set up a password.

照着敲即可【安装包265M,慢慢下载】:

zhiyong@zhiyong-ck1:~$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
SSE 4.2 supported
zhiyong@zhiyong-ck1:~$ sudo apt-get install -y apt-transport-https ca-certificates dirmngr

由于设置了密码=123456,需要敲密码才能使用客户端连接。

至此,单机版本ClickHouse安装成功。可以根据Log看到目前安装的单节点ClickHouse是22.8.4。

更多命令行使用方法可以参照官网:https://clickhouse.com/docs/zh/interfaces/cli/

贴一些命令行参数:

  • --host, -h -– 服务端的host名称, 默认是localhost。您可以选择使用host名称或者IPv4或IPv6地址。
  • --port – 连接的端口,默认值:9000。注意HTTP接口以及TCP原生接口使用的是不同端口。
  • --user, -u – 用户名。 默认值:default
  • --password – 密码。 默认值:空字符串。
  • --query, -q – 使用非交互模式查询。
  • --database, -d – 默认当前操作的数据库. 默认值:服务端默认的配置(默认是default)。
  • --multiline, -m – 如果指定,允许多行语句查询(Enter仅代表换行,不代表查询语句完结)。
  • --multiquery, -n – 如果指定, 允许处理用;号分隔的多个查询,只在非交互模式下生效。
  • --format, -f – 使用指定的默认格式输出结果。
  • --vertical, -E – 如果指定,默认情况下使用垂直格式输出结果。这与–format=Vertical相同。在这种格式中,每个值都在单独的行上打印,这种方式对显示宽表很有帮助。
  • --time, -t – 如果指定,非交互模式下会打印查询执行的时间到stderr中。
  • --stacktrace – 如果指定,如果出现异常,会打印堆栈跟踪信息。
  • --config-file – 配置文件的名称。
  • --secure – 如果指定,将通过安全连接连接到服务器。
  • --history_file — 存放命令历史的文件的路径。
  • --param_<name> — 查询参数配置查询参数.

fe00::0 ip6-localnet

可以看到只能使用localhost作为-h的参数。。。使用IP及host都会失败,也是醉了。

在另一台Ubuntu的dev机器只安装ClickHouse的Client:

目前这状态显然是不正常的。正常情况需要能够远程连接到服务器,正常人谁会localhost访问。。。

DB::NetException: Connection refused (192.168.88.22:9000). (NETWORK_ERROR)这个问题必须解决,否则之后通过JDBC等方式远程访问大概率也不正常。
