ubuntu升级软件和安装Nginx

首先看下有没有需要升级的软件

# apt list --upgradable
Listing... Done
linux-generic/focal-updates 5.4.0.60.63 amd64 [upgradable from: 5.4.0.54.57]
linux-headers-generic/focal-updates 5.4.0.60.63 amd64 [upgradable from: 5.4.0.54.57]
linux-image-generic/focal-updates 5.4.0.60.63 amd64 [upgradable from: 5.4.0.54.57]

还好，刚才已经把软件包升级过了，现在只要升级系统就可以。

升级软件包命令

sudo apt-get update 更新源
sudo apt-get upgrade 更新已安装的包

升级系统命令如下

sudo apt-get dist-upgrade 升级系统

然后在看下，都是最新的了。

#apt list --upgradable
Listing... Done

root@MDaliyun ~ # sudo apt update

下来安装Nginx

安装Nginx

sudo apt install nginx

查看Nginx状态

 sudo systemctl status nginx

root@MDaliyun / # vi /etc/nginx/nginx.conf

编辑 nginx.conf 文件。
找到 server{…}，并将 server 大括号中相应的配置信息替换为如下内容。用于取消对 IPv6 地址的监听，同时配置 Nginx，实现与 PHP 的联动。

server {
 listen       80;
 root   /usr/share/nginx/html;
 server_name  localhost;
 #charset koi8-r;
 #access_log  /var/log/nginx/log/host.access.log  main;
 #
 location / {
       index index.php index.html index.htm;
 }
 #error_page  404              /404.html;
 #redirect server error pages to the static page /50x.html
 #
 error_page   500 502 503 504  /50x.html;
 location = /50x.html {
   root   /usr/share/nginx/html;
 }
 #pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
 #
 location ~ .php$ {
   fastcgi_pass   127.0.0.1:9000;
   fastcgi_index  index.php;
   fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
   include        fastcgi_params;
 }
}
