安装单节点clickhouse

单节点安装跟集群安装都需要提前把clickhouse-server软件装好。
单节点与集群的区别就是一个连接了zookeeper，另外一个只读本地文件。
单节点
前置检查
CPU是否支持sse4_2
centos系统查看方法：
[root@clickhouse01 ~]# grep -c sse4_2 /proc/cpuinfo
1
运行前置脚本
前置脚本目的是拉去yum源， 如果是离线安装，也可以自己取yum源指向的节点下载好安装包。
- clickhouse-common-static-20.8.3.18-1.el7.x86_64.rpm
- clickhouse-client-20.8.3.18-1.el7.x86_64.rpm
- clickhouse-server-common-20.8.3.18-1.el7.x86_64.rpm
- clickhouse-server-20.8.3.18-1.el7.x86_64.rpm
- 先挂载ISO 我的系统版本是
[root@192 ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
- 运行脚本
[root@192 ~]# curl -s https://packagecloud.io/install/repositories/altinity/clickhouse/script.rpm.sh | sudo bash
...

格式化新的分区
格式化分区的目的是为了存放clickhouse的数据
pvcreate /dev/sdb
vgcreate vgdata /dev/sdb
lvcreate -l 5119 vgdata
[root@localhost ~]# mkfs.xfs /dev/vgdata/lvol0
meta-data=/dev/vgdata/lvol0 isize=512 agcount=4, agsize=1310464 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=5241856, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
## 使用yum安装之后,如果希望重新挂载这个目录,则需要授权给clickhouse用户
[root@localhost lib]# pwd
/var/lib
[root@localhost lib]# ls -ld clickhouse/
drwx------ 2 clickhouse clickhouse 4096 Nov 28 10:31 clickhouse/
[root@localhost lib]# mount /dev/mapper/vgdata-lvol0 /var/lib/clickhouse/
[root@localhost lib]# chown -R clickhouse:clickhouse /var/lib/clickhouse/
[root@localhost lib]# chmod 700 clickhouse/
[root@localhost lib]# echo "/dev/mapper/vgdata-lvol0 /var/lib/clickhouse/ xfs defaults 0 0" >> /etc/fstab
使用yum安装
使用yum安装
yum install -y clickhouse-server clickhouse-client
[root@192 ~]# yum install -y clickhouse-server clickhouse-client

查看启动状态
安装好默认就启动了。 一般生产环境都不是自动启动的。 不然体现不出运维的价值了。
测试环境无所谓，我这里改成随着系统启动而启动。
[root@192 ~]# systemctl enable clickhouse-server

配置clickhouse用户
如果希望使用clickhouse用户管理数据库，可以重新配置用户基本信息。
- 家目录
[root@localhost ~]# grep clickhouse /etc/passwd
clickhouse:x:998:996:Clickhouse server:/var/lib/clickhouse:/sbin/nologin
[root@localhost ~]# mkdir /home/clickhouse
[root@localhost ~]# usermod -d /home/clickhouse clickhouse
[root@localhost ~]# grep clickhouse /etc/passwd
clickhouse:x:998:996:Clickhouse server:/home/clickhouse:/sbin/nologin
[root@localhost ~]# usermod -s /bin/bash clickhouse
[root@localhost ~]# grep clickhouse /etc/passwd
clickhouse:x:998:996:Clickhouse server:/home/clickhouse:/bin/bash
[root@localhost ~]# cp -a /etc/skel/. /home/clickhouse

配置clickhouse
- clickhouse 服务端默认的配置文件是/etc/clickhouse-server/config.xml
打开远程监听
-
jdbc的连接端口是8123
-
console 的连接端口是9000
从下面lsof结果看 cslistener就是9000端口，这个名称引用了 /etc/services ，可以尝试查看这个文件的9000端口，名称就是cslistener。
如果手欠调整了这个名称，假如改成ckport， 则lsof返回的就是自定义名称。
[root@192 ~]# vi /etc/clickhouse-server/config.xml
添加配置，默认是注释的，可以打开注释。
<listen_host>::1</listen_host>
<listen_host>0.0.0.0</listen_host>
这俩选项都得打开，否则登录的时候会报错
报错内容：Code: 210. DB::NetException: Connection refused (localhost:9000)
