背景
作為一個Linux狗，必須要掌握一個專門的系統監控工具，能随時了解系統資源的占用情況，如應用的記憶體使用規律，應用的網絡峰值時段，CPU使用情況等資訊，對優化應用性能，保證伺服器健康運作有着極為重要的作用。
工具
netdata
Netdata是一款秒級資料收集與可視化呈現的Linux伺服器性能監測工具，他具有這樣一些特性：
- 高實時性：Netdata是用純C編寫的，關鍵系統插件也是用C語言編寫的。 它的速度隻能與本機控制台系統管理工具進行比較。當netdata在現代計算機上運作時（即使在CELERON處理器上），大多數圖表查詢都會在不到3毫秒的時間内得到回複！
- 不占用系統IO：除了日志系統外，netdata将不會使用任何磁盤的IO資源，您也可以通過配置檔案禁用掉日志系統。
- 不需要root權限
- 自帶Web服務系統
- 開箱即用，上手不需要寫任何配置
- 可視化的QOS
- 安裝便捷，根據安裝文檔訓示，有些系統可以直接從軟體庫中安裝，樹莓派上我通過克隆安裝成功，CentOS上有一鍵安裝腳本
- 告警系統，通過配置檔案，我們可以配置netdata在某些名額達到閥值的時候進行告警。
nginx
鼎鼎大名的代理伺服器，不用多說。
過程
本次安裝的機器是CentOS7 64位，我們選擇64位的安裝腳本
bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)
接下來它會自動下載下傳安裝包

You are about to install netdata to this system.
netdata will be installed at:
/opt/netdata
The following changes will be made to your system:
# USERS / GROUPS
User 'netdata' and group 'netdata' will be added, if not present.
# LOGROTATE
This file will be installed if logrotate is present.
- /etc/logrotate.d/netdata
# SYSTEM INIT
This file will be installed if this system runs with systemd:
- /etc/systemd/system/netdata.service
or, for older Centos, Debian/Ubuntu or OpenRC Gentoo:
- /etc/init.d/netdata will be created
This package can also update a netdata installation that has been
created with another version of it.
Your netdata configuration will be retained.
After installation, netdata will be (re-)started.
netdata re-distributes a lot of open source software components.

安裝後預設是通過
http://xxx:19999/
通路
由于netdata沒有帳号密碼體系，為保護伺服器隐私，我們要使用nginx反代，通過域名通路，并使用賬号密碼授權。
首先，我們安裝apache工具集，我們需要其中的
htpasswd
為我們生成使用者資訊（PS：網上找到的資料是apache2-utils，但我們在CentOS7的源中已經搜尋不到這個包）。
yum install httpd-tools -y
安裝過程如下：
Loaded plugins: fastestmirror, langpacks
Repository epel is listed more than once in the configuration
Loading mirror speeds from cached hostfile

接下來建立目錄，建立賬号
mkdir /usr/local/nginx
htpasswd -c /usr/local/nginx/passwd.db username
pwd
re-type pwd
添加一個nginx的配置
vim /etc/nginx/conf.d/netdata.conf
，内容如下
upstream netdatahttp
{
server 127.0.0.1:19999;
}
server {
listen *:80;
server_name netdata.xxx.com;
auth_basic "netdata";
auth_basic_user_file /usr/local/nginx/passwd.db;
location /
{
proxy_pass http://netdatahttp;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real_IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
打開域名測試一下效果
要求輸入賬号密碼
