卸载clickhouse
如果没有安装过clickhouse可以跳转至安装部分
1.首先查看 clickhouse-server 服务状态 如果服务是开启的 请关闭它
systemctl status clickhouse-server # 查看服务状态
systemctl stop clickhouse-server # 关闭服务2.删除之前安装过clickhouse产生的目录和文件
rm -rf /var/lib/clickhouse
rm -rf /etc/clickhouse-*
rm -rf /var/log/clickhouse-server3.删除clickhouse所有解压过的安装包
cd /opt/module/clickhouse/ # 此教程将安装包解压至/opt/module/clickhouse/
rm -rf ./*离线安装clickhouse
1、首先准备安装clickhouse所需的安装包 此教程放在了/opt/software/clickhouse/中
[rootbigdata1 clickhouse]# cd /opt/software/clickhouse/
[rootbigdata1 clickhouse]# ll
total 1020904
-rw-r--r-- 1 root root 82788 Apr 29 2022 clickhouse-client-21.9.4.35.tgz
-rw-r--r-- 1 root root 188699225 Apr 29 2022 clickhouse-common-static-21.9.4.35.tgz
-rw-r--r-- 1 root root 856509550 Apr 29 2022 clickhouse-common-static-dbg-21.9.4.35.tgz
-rw-r--r-- 1 root root 103467 Apr 29 2022 clickhouse-server-21.9.4.35.tgz2、将所有安装包解压至目标目录
cd /opt/software/clickhouse/for i in /opt/software/clickhouse/*;do tar -zxf $i -C /opt/module/clickhouse/;done[rootbigdata1 clickhouse]# cd /opt/module/clickhouse/[rootbigdata1 clickhouse]# ll
total 0
drwxr-xr-x 5 root root 43 Sep 23 2021 clickhouse-client-21.9.4.35
drwxr-xr-x 4 root root 32 Sep 23 2021 clickhouse-common-static-21.9.4.35
drwxr-xr-x 4 root root 32 Sep 23 2021 clickhouse-common-static-dbg-21.9.4.35
drwxr-xr-x 6 root root 54 Sep 23 2021 clickhouse-server-21.9.4.35
3、严格按照顺序执行安装脚本
cd /opt/module/clickhouse/clickhouse-common-static-21.9.4.35/install/doinst.shclickhouse-common-static-dbg-21.9.4.35/install/doinst.shclickhouse-server-21.9.4.35/install/doinst.shclickhouse-client-21.9.4.35/install/doinst.sh执行到第三个安装脚本时会要求设置default用户的密码可设置为123456
还会要求输入y/n:Allow server to accept connections from the network (default is localhost only), [y/N] ,这里推荐填y
4、修改配置文件
首先需要修改/etc/clickhouse-server/config.d/listen.xml 将listen_host::/listen_host 修改为 listen_host0.0.0.0/listen_host (如果服务器支持ipv6则不需要改)
vim /etc/clickhouse-server/config.d/listen.xmlyandexlisten_host0.0.0.0/listen_host
/yandex然后需要修改/etc/clickhouse-server/config.xml
将第82、622、632、638、646、652、661、668、685行的9000修改为9001 因为9000端口会和hdfs的端口冲突
vim /etc/clickhouse-server/config.xml[rootbigdata1 clickhouse]# cat -n /etc/clickhouse-server/config.xml | grep 900182 tcp_port9001/tcp_port622 port9001/port632 port9001/port638 port9001/port646 port9001/port652 port9001/port661 port9001/port668 port9001/port685 port9001/port5、启动服务并查看服务状态
systemctl start clickhouse-server
systemctl status clickhouse-server● clickhouse-server.service - ClickHouse Server (analytic DBMS for big data)Loaded: loaded (/etc/systemd/system/clickhouse-server.service; enabled; vendor preset: disabled)Active: active (running) since Fri 2024-05-10 20:55:18 CST; 5s agoMain PID: 17660 (clckhouse-watch)CGroup: /docker/9c3a9bea4923101aab063d7028419e9d0e5d812f6d5bacc91922eb1f310dcdf2/system.slice/clickhouse-server.service├─17660 clickhouse-watchdog --config/etc/clickhouse-server/config.xml --pid-file/run/clickho...└─17661 /usr/bin/clickhouse-server --config/etc/clickhouse-server/config.xml --pid-file/run/...‣ 17660 clickhouse-watchdog --config/etc/clickhouse-server/config.xml --pid-file/run/clickho...安装完成~
