clickhouse安裝(單機版)—服務安裝

1、添加hadoop賬號
2、設置hadoop賬號具有sudo權限

#切換root賬號，執行visudo
[root@bigdata-k-01 ~]# visudo
#在visudo 中root    ALL=(ALL)       ALL下添加一行hadoop
......
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
hadoop  ALL=(ALL)       ALL
.....

3、校驗cpu是否支持sse 4.2

[hadoop@bigdata-k-01 ~]$  grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
SSE 4.2 supported

4、安裝
https://clickhouse.tech/docs/en/getting_started/install/

#添加rpm repository
[hadoop@bigdata-k-01 ~]$ sudo yum install yum-utils
[hadoop@bigdata-k-01 ~]$ sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
[hadoop@bigdata-k-01 ~]$ sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64

#安裝
[hadoop@bigdata-k-01 ~]$ sudo yum install clickhouse-server clickhouse-client

#啓動
[hadoop@bigdata-k-01 ~]$ sudo service clickhouse-server start
Start clickhouse-server service: Path to data directory in /etc/clickhouse-server/config.xml: /var/lib/clickhouse/
Creating directory /var/lib/clickhouse/
Changing owner of [/var/lib/clickhouse/] to [clickhouse:clickhouse]
DONE
#日誌文件在
[hadoop@bigdata-k-01 ~]$ ll /var/log/clickhouse-server/
total 24
-rw-r----- 1 clickhouse clickhouse  2172 Apr 14 15:51 clickhouse-server.err.log
-rw-r----- 1 clickhouse clickhouse 12377 Apr 14 15:52 clickhouse-server.log
-rw-r----- 1 clickhouse clickhouse   568 Apr 14 15:51 stderr.log
-rw-r----- 1 clickhouse clickhouse     0 Apr 14 15:51 stdout.log

5、執行

[hadoop@bigdata-k-01 ~]$  clickhouse-client
ClickHouse client version 20.3.5.21 (official build).
Connecting to localhost:9000 as user default.

安裝完成。
接下來進行數據導入：clickhouse 數據導入

6、啓動的時候可能會包數據目錄或日誌目錄沒有權限

[root@bigdata-k-01 0]# service clickhouse-server start
Start clickhouse-server service: Path to data directory in /etc/clickhouse-server/config.xml: /mnt/disk/0/clickhouse/
Changing owner of [/var/log/clickhouse-server/*] to [clickhouse:clickhouse]
chown: cannot access '/var/log/clickhouse-server/*': No such file or directory
Changing owner of [/var/log/clickhouse-server] to [root:clickhouse]

[root@bigdata-k-01 clickhouse-server]# service clickhouse-server start
Start clickhouse-server service: Path to data directory in /etc/clickhouse-server/config.xml: /mnt/disk/0/clickhouse/
Changing owner of [/var/log/clickhouse-server/*] to [clickhouse:clickhouse]
Changing owner of [/var/log/clickhouse-server] to [root:clickhouse]
UNKNOWN

解決：可以指定有權限的目錄或者將目錄的權限修改爲clickhouse:clickhouse

[root@ip-10-130-68-178 0]# cat /etc/clickhouse-server/config.xml | grep "/var/lib/clickhouse"
    <path>/var/lib/clickhouse/</path>
    <tmp_path>/var/lib/clickhouse/tmp/</tmp_path>
    <user_files_path>/var/lib/clickhouse/user_files/</user_files_path>
    <access_control_path>/var/lib/clickhouse/access/</access_control_path>
    <format_schema_path>/var/lib/clickhouse/format_schemas/</format_schema_path>

[root@ip-10-130-68-178 log]# pwd
/var/log
[root@ip-10-130-68-178 log]# chown clickhouse:clickhouse clickhouse-server

#啓動前一定要把日誌目錄和數據目錄提前創建好切必須把用戶和組更新爲clickhouse
[root@ip-10-130-68-178 log]# service clickhouse-server status
clickhouse-server service is running
[root@ip-10-130-68-178 0]# cat /etc/clickhouse-server/config.xml | grep "/var/lib/clickhouse"
    <path>/var/lib/clickhouse/</path>
    <tmp_path>/var/lib/clickhouse/tmp/</tmp_path>
    <user_files_path>/var/lib/clickhouse/user_files/</user_files_path>
    <access_control_path>/var/lib/clickhouse/access/</access_control_path>
    <format_schema_path>/var/lib/clickhouse/format_schemas/</format_schema_path>

#將數據目錄修改爲/mnt/disk/0/clickhouse目錄
[root@ip-10-130-68-178 log]# sed -i "s/\/var\/lib\/clickhouse/\/mnt\/disk\/0\/clickhouse/g" /etc/clickhouse-server/config.xml

[root@ip-10-130-68-178 log]# pwd
/var/log
#在/var/log下創建clickhouse-server 和 clickhouse-lient目錄，並將目錄權限改爲clickhouse:clickhouse
[root@ip-10-130-68-178 log]# mkdir dir clickhouse-server  clickhouse-lient
[root@ip-10-130-68-178 log]# chown clickhouse:clickhouse clickhouse-server

[root@ip-10-130-68-178 log]# chown clickhouse:clickhouse clickhouse-client

#然後重新啓動即可
