1. 安装jdk(101/102/103上执行)
[root@node101 /usr/local/src]# tar xf jdk-8u171-linux-x64.tar.gz -C /usr/local/
[root@node101 /usr/local/src]# ln -s /usr/local/jdk1.8.0_171/ /usr/local/jdk1.8
[root@node101 /usr/local/src]# vim /etc/profile.d/jdk.sh #添加以下内容
export JAVA_HOME=/usr/local/jdk1.8
export JRE_HOME=/usr/local/jdk1.8
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

[root@node101 /usr/local/src]# tar xf zookeeper-3.4.12.tar.gz -C /usr/local/
[root@node101 /usr/local/src]# ln -s /usr/local/zookeeper-3.4.12/ /usr/local/zookeeper

[root@node101 /usr/local/src]# mkdir /data/zookeeper
[root@node101 /usr/local/src]# vim /data/zookeeper/myid #101为1，102为2，103为3
1

[root@node101 /usr/local/src]# chown keung.keung /data/zookeeper -R
[root@node101 /usr/local/src]# su - keung -c "/usr/local/zookeeper/bin/zkServer.sh start"

3. 安装ck(100/101/102/103上执行)
(1). 安装yum源
[root@node101 /usr/local/src]# curl -s https://packagecloud.io/install/repositories/altinity/clickhouse/script.rpm.sh | bash
The repository is setup! You can now install packages.
(2). 安装ck
[root@node101 /usr/local/src]# yum -y install clickhouse-server clickhouse-client clickhouse-server-common clickhouse-compressor
[root@node101 /usr/local/src]# mkdir /data/clickhouse -p

(3). 配置config.xml
[root@node101 /usr/local/src]# vim /data/clickhouse/config.xml
<?xml version="1.0"?>

(6). 修改启动脚本
[root@node101 /usr/local/src]# vim /etc/init.d/clickhouse-server
CLICKHOUSE_LOGDIR=/data/clickhouse/logs
LOCALSTATEDIR=/data/clickhouse
CLICKHOUSE_CONFIG=/data/clickhouse/config.xml
LOCKFILE=/data/clickhouse/clickhouse.lock
CLICKHOUSE_PIDDIR=/data/clickhouse
CLICKHOUSE_PIDFILE="/data/clickhouse/clickhouse.pid"

(7). 修改权限
[root@node101 /usr/local/src]# mkdir /data/clickhouse/logs
[root@node101 /usr/local/src]# chown clickhouse.clickhouse /data/clickhouse/ -R

(8). 启动ck
[root@node101 /usr/local/src]# /etc/init.d/clickhouse-server start
Start clickhouse-server service: Path to data directory in /data/clickhouse/config.xml: /data/clickhouse/
DONE

您好，大神我根据你的clickhouse集群安装文档，用四台虚拟机安装了clickhouse,但是启动clickhouse-client -m --password ****,出现报错：Code: 210. DB::NetException: Connection refused (localhost:9000, ::1)
；我查看了错误日志发现： Application: DB::Exception: Cannot lock file /data/clickhouse/status. Another server instance in same directory is already running.（不能锁定这个 /data/clickhouse/status 目录下的status文件，在相同目录下有另一个服务器实例已经在运行），我不明白报错是什么意思？另外我看了status这个文件里是在运行clickhouse-server的进程。
您能告诉我我的配置是哪里错了，为什么拒绝连接？我是按照您给的配置呀

    您好，我看了error.log,报错信息是： Application: DB::Exception: Cannot lock file /data/clickhouse/status. Another server instance in same directory is already running.
    
    我的/etc/init.d/clickhouse-server start 这个都能启动成功，就是clickhouse-client -m --password ****,出现报错：Code: 210. DB::NetException: Connection refused (localhost:9000, ::1）

      上面的问题解决了，还是clickhouse-client -m --password ****出现报错：Code: 210. DB::NetException: Connection refused (localhost:9000, ::1），我看了下错误日志： void DB::DDLWorker::run(): Code: 999, e.displayText() = Coordination::Exception: All connection tries failed while connecting to ZooKeeper. Addresses: 192.xxx.xx.xxx:2181, 192.xxx.xx.xxx:2181, 192.xxx.xx.xxx:2181,报错说不能连接zookeeper,
      然后我查看 cat zookeeper.out 文件，hdp02这台机子的zookeeper.out文件内容觉得有问题：2019-01-07 15:43:49,623 [myid:2] - INFO [ProcessThread(sid:2 cport:-1)::PrepRequestProcessor@645] - Got user-level KeeperException when processing sessionid:0x168273a00510000 type:create cxid:0x1 zxid:0x250000000f txntype:-1 reqpath:n/a Error Path:/clickhouse Error:KeeperErrorCode = NodeExists for /clickhouse。我不知道为什么连接zookeeper2181端口失败？您能帮我分析下吗？

        检查一下防火墙看下端口通不通，selinux关了没有

  Code: 210. DB::NetException: Connection refused (localhost:9000, ::1)这个问题是添加0.0.0.0造成的吗，怎么解决

  chickhouse把数据分片进行储存，也就是划分为一个或多shard，每个shard里面一般包含两个或以上的副本，你可以把其他的一个副本停掉，看一下是否还可以使用

大神你好，我有设置权限，chown clickhouse.clickhouse /data/clickhouse/ -R，但是sudo -u clickhouse clickhouse-server --config-file=/etc/clickhouse-server/config.xml的时候仍然提示Couldn't save preprocessed config to /data/clickhouse/clickhousedata//preprocessed_configs/config.xml: Access to file denied: /data/clickhouse
Poco::Exception. Code: 1000, e.code() = 13, e.displayText() = Access to file denied: /data/clickhouse，请问这是什么原因呢？

  你看下/data/clickhouse/clickhousedata//preprocessed_configs/目录是否存在，可能需要事先创建目录
