**1，安装包系在路径：
https://mirrors.aliyun.com/clickhouse/tgz/stable/\*\*
2，环境准备
1.配置主机名
hostnamectl set-hostname ${hostname}
2.配置hosts
ip hostname
3.关闭防火墙
vim /etc/selinux/config 改为 SELINUX=disabled
ps：
1）关闭systemctl stop firewalld
2）查看防火墙端口是否开发
lsof -i:80 or netstat -apnt |grep 80
重启防火墙：systemctl restart firewalld.service
查看所有开放端口：firewall-cmd --list-ports
查看防火墙状态：firewall-cmd --state
开启防火墙：systemctl start firewalld.service
设置防火墙开机自启动：systemctl enable firewalld.service
重启防火墙：systemctl restart firewalld.service
3，clickhouse 前期准备
1.创建用户
useradd clickhouse
passwd clickhouse
2.clickhouse用户授权
visudo
添加 clickhouse ALL=(ALL) ALL
4.jdk 安装
5.zk 安装
三：安装clickhouse
1.安装
sudo rpm -ivh clickhouse-*.rpm
2. 修改config.xml 文件
yaml

</yandex>2.修改users.xml
yaml
<?xml version="1.0"?>
<yandex>
<!-- Profiles of settings. -->
<profiles>
<!-- Default settings. -->
<default>
<!-- Maximum memory usage for processing single query, in bytes. -->
<max_memory_usage>10000000000</max_memory_usage>

<skip_unavailable_shards>1</skip_unavailable_shards> <!-- 1=true，0=false -->
<!-- How to choose between replicas during distributed query processing.
random - choose random replica from set of replicas with minimum number of errors
nearest_hostname - from set of replicas with minimum number of errors, choose replica
with minimum number of different symbols between replica's hostname and local hostname
(Hamming distance).
in_order - first live replica is chosen in specified order.
first_or_random - if first replica one has higher number of errors, pick a random one from replicas with minimum number of errors.
-->
<load_balancing>random</load_balancing>
</default>
<!-- Profile that allows only read queries. -->
<readonly>
<readonly>1</readonly>
</readonly>
</profiles>
<!-- Users and ACL. -->
<users>
<!-- If user name was not specified, 'default' user is used. -->
<default>
<!-- Password could be specified in plaintext or in SHA256 (in hex format).
If you want to specify password in plaintext (not recommended), place it in 'password' element.
Example: <password>qwerty</password>.
Password could be empty.
If you want to specify SHA256, place it in 'password_sha256_hex' element.
Example: <password_sha256_hex>65e84be33532fb784c48129675f9eff3a682b27168c0ea744b2cf58ee02337c5</password_sha256_hex>
Restrictions of SHA256: impossibility to connect to ClickHouse using MySQL JS client (as of July 2019).
If you want to specify double SHA1, place it in 'password_double_sha1_hex' element.
Example: <password_double_sha1_hex>e395796d6546b1b65db9d665cd43f0e858dd4303</password_double_sha1_hex>
If you want to specify a previously defined LDAP server (see 'ldap_servers' in main config) for authentication, place its name in 'server' element inside 'ldap' element.
Example: <ldap><server>my_ldap_server</server></ldap>
How to generate decent password:
Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
In first line will be password and in second - corresponding SHA256.
How to generate double SHA1:
Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'
In first line will be password and in second - corresponding double SHA1.

<password></password>
<!-- List of networks with open access.
To open access from everywhere, specify:
<ip>::/0</ip>
To open access only from localhost, specify:
<ip>::1</ip>
<ip>127.0.0.1</ip>
Each element of list has one of the following forms:
<ip> IP-address or network mask. Examples: 213.180.204.3 or 10.0.0.1/8 or 10.0.0.1/255.255.255.0
2a02:6b8::3 or 2a02:6b8::3/64 or 2a02:6b8::3/ffff:ffff:ffff:ffff::.
<host> Hostname. Example: server01.yandex.ru.
To check access, DNS query is performed, and all received addresses compared to peer address.
<host_regexp> Regular expression for host names. Example, ^server\d\d-\d\d-\d\.yandex\.ru$
To check access, DNS PTR query is performed for peer address and then regexp is applied.
Then, for result of PTR query, another DNS query is performed and all received addresses compared to peer address.
Strongly recommended that regexp is ends with $
All results of DNS requests are cached till server restart.
-->
<networks incl="networks" replace="replace">

3.配置metrika.xml 文件
yaml

<host>bigdata57</host> <!-- 节点 IP -->
<port>9000</port> <!-- TCP 端口（正确） -->
</replica>
</shard>
<!-- 分片2 -->
<shard>
<replica>
<host>bigdata93</host>
<port>9000</port>
</replica>
</shard>
</shards_0replicas>
</clickhouse_remote_servers>
<!-- ZooKeeper 配置（修正标签：<host> → <node>） -->
