2023-12-22 14:30:33

一.下载安装包

二.集群文件配置修改?

ip地址服务名称
192.168.110.110influxdb,meta
192.168.110.111influxdb,meta
192.168.110.118meta

1.influxdb-meta.conf配置文件修改

meta至少三个节点修改配置比较简单

hostname = "192.168.110.110"

dir = "/data/var/lib/influxdb/meta"

hostname = "192.168.110.111"

dir = "/data/var/lib/influxdb/meta"

hostname = "192.168.110.118"

dir = "/data/var/lib/influxdb/meta"

2.influxdb.conf配置修改:红色为修改参数

influxdb-mate.conf每台只需要修改下面参数

hostname = "192.168.110.110"

[meta].
? dir = "/data/var/lib/influxdb/meta"

第一个influx的配置influxdb.conf修改

hostname = "192.168.110.110"
[meta]
? # Directory where the cluster metadata is stored.
? dir = "/data/var/lib/influxdb/meta"
[data]
? dir = "/data/var/lib/influxdb/data"
? wal-dir = "/data/var/lib/influxdb/wal"
? wal-fsync-delay = "1ms"
? index-version = "tsi1"
? cache-max-memory-size = "48g"
? cache-snapshot-memory-size = "4096m"
? max-concurrent-compactions = 12
? series-id-set-cache-size = 100

[coordinator]
? max-select-point = 1000000
? max-select-series = 1000000

[hinted-handoff]

# The directory where the hinted handoff queues are stored.
dir = "/data/var/lib/influxdb/hh"

第二个influx的配置influxdb.conf修改

hostname = "192.168.110.111"
[meta]
? # Directory where the cluster metadata is stored.
? dir = "/data/var/lib/influxdb/meta"
[data]
? dir = "/data/var/lib/influxdb/data"
? wal-dir = "/data/var/lib/influxdb/wal"
? wal-fsync-delay = "1ms"
? index-version = "tsi1"
? cache-max-memory-size = "48g"
? cache-snapshot-memory-size = "4096m"
? max-concurrent-compactions = 12
? series-id-set-cache-size = 100

[coordinator]
? max-select-point = 1000000
? max-select-series = 1000000

[hinted-handoff]

# The directory where the hinted handoff queues are stored.
dir = "/data/var/lib/influxdb/hh"

三.集群构建启动

1.meta元数据集群的构建

启动meta集群(所有的mate节点上执行)

nohup influxd-meta -config /data/influxdb/etc/influxdb/influxdb-meta.conf > nohup.out 2>&1 &

在其中一个节点上执行

influxd-ctl add-meta 192.168.110.110:8091 influxd-ctl add-meta 192.168.110.111:8091 influxd-ctl add-meta 192.168.110.88:8091

2.influxdb集群服务

启动data服务(所有influx的数据节点上执行)

nohup influxd -config /data/influxdb/etc/influxdb/influxdb.conf > nohup.out 2>&1 &

将data节点加入集群(其中一个data节点上)

influxd-ctl add-data 192.168.10.110:8088 influxd-ctl add-data 192.168.10.111:8088

四.配置负载均衡

nginx配置参数如下


#user ?nobody;
worker_processes ?1;

#error_log ?logs/error.log;
#error_log ?logs/error.log ?notice;
#error_log ?logs/error.log ?info;

#pid ? ? ? ?logs/nginx.pid;


events {
? ? worker_connections ?1024;
}


http {
? ? include ? ? ? mime.types;
? ? default_type ?application/octet-stream;

? ? #log_format ?main ?'$remote_addr - $remote_user [$time_local] "$request" '
? ? # ? ? ? ? ? ? ? ? ?'$status $body_bytes_sent "$http_referer" '
? ? # ? ? ? ? ? ? ? ? ?'"$http_user_agent" "$http_x_forwarded_for"';

? ? #access_log ?logs/access.log ?main;

? ? sendfile ? ? ? ?on;
? ? #tcp_nopush ? ? on;

? ? #keepalive_timeout ?0;
? ? keepalive_timeout ?65;

? ? #gzip ?on;
?? ?upstream influxdb {
? ? ? ? server 192.168.110.110:8086;
? ? ? ? server 192.168.110.111:8086;
? ? }
? ? server {
? ? ? ? listen ? ? ? 8181;
? ? ? ? server_name ?localhost;

? ? ? ? #charset koi8-r;

? ? ? ? #access_log ?logs/host.access.log ?main;

? ? ? ? location / {
?? ? ? ? ? ?proxy_set_header Host $proxy_host;
? ? ? ? ? ?? ?proxy_pass ? http://influxdb/;
? ? ? ? }
? ? ? ? error_page ? 500 502 503 504 ?/50x.html;
? ? ? ? location = /50x.html {
? ? ? ? ? ? root ? html;
? ? ? ? }

? ? }

}
?

负载均衡测试

数据测试写入

curl -i -XPOST 'http://192.168.110.110:8181/influx/write?db=test' --data-binary 'mymeasurement,mytag=1 myfield=90'

数据查询

curl -XPOST "http://192.168.10.110:8181/influx/query?db=test" --data-urlencode "q=Select * from mymeasurement" --header "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZXhwIjoxNjc5NjQyNTEyfQ.7mIPMjB60kFGFQuTSyf7KvYF921MkMmL662_icTfvRQ"

五.命令手册

influxd-meta config 显示所有meta的配置

influxd config 显示所有influxdata的配置

influx-ctl show 显示集群节点

create database iot_env_data

创建用户设置密码

create user iot_admin with password 'xxx1' with all privileges
