linux nginx安裝（基礎版）

• 系統版本：centos7

• 檢查系統是否安裝了gcc、pcre-devel、zlib-devel、openssl-devel

  yum list installed | grep "gcc"
  yum list installed | grep "pcre-devel"
  yum list installed | grep "zlib-devel"
  yum list installed | grep "openssl-devel"
  

• 如果沒有安裝則執行安裝命令

  yum -y install gcc pcre-devel zlib-devel openssl openssl-devel
   
  

• 下載nginx安裝包

  官方主頁：https://nginx.org/download/

  或者執行命令

  如果沒有安裝wget執行
  yum -y install wget
  wget https://nginx.org/download/nginx-1.18.0.tar.gz
  

• 解壓安裝包，編譯並安裝

  tar -zxvf nginx-1.18.0.tar.gz
  cd nginx-1.18.0
  ./configure --prefix=/usr/local/nginx
  make 
  make install

  systemctl stop firewalld.service
  systemctl disable firewalld.service

  vim /etc/rc.d/rc.local
  #增加nginx啟動引數
  /usr/local/nginx/sbin/nginx
  
  注意：vi /etc/rc.d/rc.local預設沒有執行的許可權，需要授權
