編譯安裝

1.解決依賴關系

yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel //安裝編譯的依賴

2.下載nginx原始碼包

yum -y install wget
wget http://nginx.org/download/nginx-1.19.5.tar.gz

3.解壓nginx原始碼包并編譯開始安裝

tar xzf nginx-1.19.5.tar.gz
cd nginx-1.19.5
./configure --prefix=/srv/nginx
make && make install 

nginx大部分常用模塊，編譯時./configure --help以–without開頭的都默認安裝，

–prefix=PATH ： 指定nginx的安裝目錄，如 /srv/nginx

4.啟動

/srv/nginx/sbin/nginx -c /srv/nginx/conf/nginx.conf    //nginx啟動并選擇要啟動的組態檔
kill -15  `cat /srv/nginx/logs/nginx.pid`	//nginx啟動后可以根據它啟動的pid來進行結束行程
 /srv/nginx/sbin/nginx -s reload -c /srv/nginx/conf/nginx.conf //nginx啟動后重啟

5.撰寫啟動腳本

翻到最后

匯入編譯完安裝包

1.下載編譯完的原始碼包并解壓

cd /srv && curl -o nginx.tar.gz http://182.92.165.158/nginx.tar.gz  //切換到srv目錄下開始下載
cd /srv && tar xzf nginx.tar.gz  //解壓

2.配置log目錄和web目錄

mkdir -p /data/web/www
mkdir -p /data/log/nginx/
echo "test" > /data/log/nginx/index.html

3.啟動腳本使用

wget http://182.92.165.158/nginx_install.sh
bash nginx_install start    //使用引數有：start|stop|reload|status|test

啟動腳本

#!/bin/bash

ng_b=`netstat -nlpt | grep 80`
ng_a=$?
