sudo vim /etc/security/limits.d/20-nproc.conf
发送到从节点
scp /etc/security/limits.conf cdh03:/etc/security/limits.conf scp /etc/security/limits.d/20-nproc.conf1.3.主节点安装依赖
sudo yum install -y libtool sudo yum install -y *unixODBC*1.4.取消SELINUX
sudo vim /etc/selinux/config SELINUX=disabled
查看:getenforce
从节点重复上述操作/SCP过去也可
scp -r clikchouse/ cdh03:/home/clikchouse/2.3.安装
进入文件目录后,三个节点各自执行
sudo rpm -ivh *.rpm
查看安装情况
sudo rpm -qa|grep clickhouse2.4.修改配置文件
sudo vim /etc/clickhouse-server/config.xml
把
机以外的服务器访问
发送给从节点
scp /etc/clickhouse-server/config.xml cdh03:/etc/clickhouse-server/2.5.安装中遇到的问题
- 端口被占用
修改config.xml 更改端口号即可 config.xml/tcp_port 记得重启 sudo clickhouse restart
- 用户不存在/密码错误
删除users.d文件即可
- 拒绝访问
3.登录方式这种情况一般是端口号被占用
netstat -anp |grep 9000
修改下端口号即可,
参考2.5.1
sudo systemctl start clickhouse-server clickhouse-client -m -h 127.0.0.1 或者 clickhouse-client -m -h 127.0.0.1 --port 9050 更改了端口的登录方式
