寫了個nginx編譯安裝指令碼
版本：nginx-1.19.2

#!/bin/bash

# 安裝依賴關係包
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gcc-c++ autoconf automake make &>/dev/null

# 下載安裝包
curl -O http://nginx.org/download/nginx-1.19.2.tar.gz

# 新建用來啟動nginx的使用者
useradd nginx -s /sbin/nologin

# 解壓原始碼包，進入解壓後的目錄
tar xf nginx-1.19.2.tar.gz
cd nginx-1.19.2

# 編譯安裝前的配置
./configure --prefix=/usr/local/nginx --user=nginx --with-http_realip_module  --with-http_ssl_module  --with-pcre

# 編譯安裝
make
make install

補充：nginx監聽80埠，如果apache或者Tomcat已經把80端口占用，nginx服務將會無法啟動。可以先用 netstat -anplut 檢查一下80埠是否被佔用，再考慮是殺死佔用80埠的程序，還是更改nginx監聽的埠，這裡就不細說了。
