背景
作為一個(gè)Linux狗，必須要掌握一個(gè)專門的系統(tǒng)監(jiān)控工具恼蓬，能隨時(shí)了解系統(tǒng)資源的占用情況惊完，如應(yīng)用的內(nèi)存使用規(guī)律，應(yīng)用的網(wǎng)絡(luò)峰值時(shí)段处硬，CPU使用情況等信息小槐，對(duì)優(yōu)化應(yīng)用性能，保證服務(wù)器健康運(yùn)行有著極為重要的作用。
工具
netdata
Netdata是一款秒級(jí)數(shù)據(jù)收集與可視化呈現(xiàn)的Linux服務(wù)器性能監(jiān)測(cè)工具凿跳，他具有這樣一些特性：
- 高實(shí)時(shí)性：Netdata是用純C編寫(xiě)的件豌，關(guān)鍵系統(tǒng)插件也是用C語(yǔ)言編寫(xiě)的。 它的速度只能與本機(jī)控制臺(tái)系統(tǒng)管理工具進(jìn)行比較控嗜。當(dāng)netdata在現(xiàn)代計(jì)算機(jī)上運(yùn)行時(shí)（即使在CELERON處理器上）茧彤，大多數(shù)圖表查詢都會(huì)在不到3毫秒的時(shí)間內(nèi)得到回復(fù)！
- 不占用系統(tǒng)IO：除了日志系統(tǒng)外疆栏，netdata將不會(huì)使用任何磁盤的IO資源曾掂，您也可以通過(guò)配置文件禁用掉日志系統(tǒng)。
- 不需要root權(quán)限
- 自帶Web服務(wù)系統(tǒng)
- 開(kāi)箱即用壁顶，上手不需要寫(xiě)任何配置
- 可視化的QOS
- 安裝便捷珠洗，根據(jù)安裝文檔指示，有些系統(tǒng)可以直接從軟件庫(kù)中安裝若专，樹(shù)莓派上我通過(guò)克隆安裝成功许蓖，CentOS上有一鍵安裝腳本
- 告警系統(tǒng)，通過(guò)配置文件调衰，我們可以配置netdata在某些指標(biāo)達(dá)到閥值的時(shí)候進(jìn)行告警膊爪。
nginx
鼎鼎大名的代理服務(wù)器，不用多說(shuō)嚎莉。
過(guò)程
本次安裝的機(jī)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(lái)它會(huì)自動(dòng)下載安裝包

安裝后默認(rèn)是通過(guò)http://xxx:19999/訪問(wèn)
由于netdata沒(méi)有帳號(hào)密碼體系琼懊，為保護(hù)服務(wù)器隱私阁簸，我們要使用nginx反代，通過(guò)域名訪問(wèn)哼丈，并使用賬號(hào)密碼授權(quán)启妹。
首先，我們安裝apache工具集醉旦，我們需要其中的htpasswd為我們生成用戶信息（PS：網(wǎng)上找到的資料是apache2-utils饶米，但我們?cè)贑entOS7的源中已經(jīng)搜索不到這個(gè)包）。
yum install httpd-tools -y
安裝過(guò)程如下：
Loaded plugins: fastestmirror, langpacks
Repository epel is listed more than once in the configuration

接下來(lái)創(chuàng)建目錄车胡，創(chuàng)建賬號(hào)
mkdir /usr/local/nginx
htpasswd -c /usr/local/nginx/passwd.db username
pwd
re-type pwd
添加一個(gè)nginx的配置vim /etc/nginx/conf.d/netdata.conf檬输，內(nèi)容如下
upstream netdatahttp
{
server 127.0.0.1:19999;
}
server {

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(kāi)域名測(cè)試一下效果
