安装和搭建nginx服务器

1.  下载 http://nginx.org/download/nginx-1.9.9.tar.gz

2. 在ubuntu19.04机器上安装

  

install nginx
    
    http://nginx.org/en/linux_packages.html#Debian
       
    Install the prerequisites:
    
    sudo apt install curl gnupg2 ca-certificates lsb-release
    To set up the apt repository for stable nginx packages, run the following command:
    
    echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" 
        | sudo tee /etc/apt/sources.list.d/nginx.list
    If you would like to use mainline nginx packages, run the following command instead:
    
    echo "deb http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" 
        | sudo tee /etc/apt/sources.list.d/nginx.list
    Next, import an official nginx signing key so apt could verify the packages authenticity:
    
    curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -
    Verify that you now have the proper key:
    
    sudo apt-key fingerprint ABF5BD827BD9BF62
    The output should contain the full fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 as follows:
    
    pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
          573B FD6B 3D8F BC64 1079  A6AB ABF5 BD82 7BD9 BF62
    uid   [ unknown] nginx signing key <signing-key@nginx.com>
    To install nginx, run the following commands:
    
    sudo apt update
    sudo apt install nginx
    
    
    配置文件目录： /etc/nginx

3. 启停nginx服务

http://nginx.org/en/docs/beginners_guide.html

sudo nginx

fast stop:
sudo nginx -s quit

graceful shutdown:
sudo nginx -s stop     

=======================
stop — fast shutdown
quit — graceful shutdown
reload — reloading the configuration file
reopen — reopening the log files
=========================   
kill -s QUIT 1628
ps -ax | grep nginx


4. 修改配置，搭建静态服务

sudo vim /etc/nginx/conf.d/default.conf
 
在server 中加入： 
location /images/ {
         root /data;
 }
 
 注意缩进.
 创建目录/data/images , sudo chown pascal:pascal /data/images
 
 重新加载配置：
 sudo nginx -s reload
 
 copy image:
 在/data/images加入图片 4662203.jpg
 
 访问图片：
 http://localhost/images/4392112.jpg
