ubuntu安装nginx

1.下载linux版安装包

将下载的nginx安装包上传至ubuntu系统。
解压 nginx-1.22.0.tar.gz 包：

tar -zxvf ./nginx-1.22.0.tar.gz -C /home/$USER/soft/

2.安装nginx所需的依赖

sudo apt-get install gcc

sudo apt-get install libpcre3 libpcre3-dev

sudo apt-get install zlib1g-dev

sudo apt-get install openssl libssl-dev

3.编译和安装nginx

在nginx根目录执行配置文件

./configure

编译和安装

sudo apt-get install make

sudo make && sudo make install

或者

sudo make -j32 && sudo make install

4.测试nginx是否安装成功：

/usr/local/nginx/sbin/nginx -v

5.设置开机启动

编写命令脚本

sudo touch /etc/init.d/nginx
sudo chmod a+x /etc/init.d/nginx
sudo vim /etc/init.d/nginx

#! /bin/sh
