安裝

官網提供一鍵安裝腳本
bash <(curl -Ss https://my-netdata.io/kickstart.sh)

國內使用一鍵安裝腳本需要添加參數
bash <(curl -Ss https://my-netdata.io/kickstart.sh) --stable-channel

修改主節點的配置

# 主服務器配置

# 生成uuid格式的字符串
root@cby:~# uuidgen
856a8565-75ac-441f-89e1-2d983272cfde



root@cby:~# vim /etc/netdata/stream.conf
root@cby:~# cat /etc/netdata/stream.conf
[856a8565-75ac-441f-89e1-2d983272cfde]
    enabled = yes
    default history = 3600
    default memory mode = save
    health enabled by default = auto
    allow from = *
root@cby:~# 
root@cby:~# 
# allow from 可以設置數據流的允許來源以保證安全
# destination 是主節點ip地址


# 重啟netdata
root@cby:~# systemctl restart netdata
root@cby:~# 

配置其他節點

# 其它服務器配置
root@cby:~# vim /etc/netdata/netdata.conf 
root@cby:~# cat /etc/netdata/netdata.conf
[global]
    run as user = netdata
    page cache size = 32
    dbengine multihost disk space = 256
    memory mode = none
    hostname = node-1
[web]
    mode = none
root@cby:~# 

root@cby:~# vim /etc/netdata/stream.conf
root@cby:~# cat /etc/netdata/stream.conf
[stream]
    enabled = yes
    destination = 101.43.189.29:19999
    api key = 856a8565-75ac-441f-89e1-2d983272cfde
root@cby:~# 
root@cby:~# 
# destination填寫服務端的IP和端口

# 重啟netdata
root@cby:~# systemctl restart netdata
root@cby:~# 

啟用插件

以MySQL插件為例

# 創建權限用戶
root@cby:~# mysql -u root -p

# 配置Netdata的mysql.conf
root@cby:/etc/netdata# cd /etc/netdata
root@cby:/etc/netdata# sudo ./edit-config go.d/mysql.conf

······略······
  # netdata
  - name: local
    dsn: netdata:password@unix(/var/lib/mysql/mysql.sock)
  - name: local
    dsn: netdata:password@tcp(127.0.0.1:3306)/db_test
······略······

# 異常查看
root@cby:/etc/netdata# cd /usr/libexec/netdata/plugins.d/
root@cby:/etc/netdata# sudo -u netdata -s
root@cby:/etc/netdata# ./go.d.plugin -d -m mysql

systemctl restart netdata
