安裝nginx

首先需要下載nginx安裝tar包，地址爲：http://nginx.org/download/，並將其上傳至機器，對其進行解壓

> tar -zxvf nginx-1.2.6.tar.gz

> yum -y install pcre pcre-devel zlib zlib-devel

創建nginx用戶：#useradd -s /sbin/nologin -M nginx

開始安裝：

#./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module

#make && make install

測試是否安裝成功：

echo "hadoop" >>/usr/local/nginx/html/index.html

/usr/local/nginx/sbin/nginx

curl localhost

修改vi /usr/local/nginx/conf/nginx.conf配置文件

檢測語法是否正常：/usr/local/nginx/sbin/nginx -t
重載：kill -HUP $(cat /usr/local/nginx/logs/nginx.pid)

編寫shell腳本：

#!/bin/bash

HOST="127.0.0.1"
PORT="80"

#nginx if not exeit
function ping {
  /sbin/pidof nginx |wc -l
}

#nginx  performance
function active {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Active' |awk '{print $NF}'
}
function reading {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Reading' |awk '{print $2}'
}
function writing {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Writing' |awk '{print $4}'
}
function waiting {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|grep 'Waiting' |awk '{print $6}'
}
function accepts {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $1}'
}
function handled {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $2}'
}
function requests {
  /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null|awk NR==3 |awk '{print $3}'
}
