如何为网站做优化/深圳今日重大新闻

1.用pm2部署nest

说明：如果一开始将nest直接打包放到linux服务器上用pm2执行则会报错，这是因为tsconfig.build.tsbuildinfo文件的路径以及相关依赖问题。
报错会为：什么东西找不到....
所以建议以下为步骤一步一步配置

1. 将整个nest添加压缩包直接传到的root中的任何一个目录中，在linux中解压
2. 进入nest的项目文件用npm run build进行打包
3. 此时需要下载好pm2进程管理器
4. 直接pm2 start main.js运行后端项目
5. 此时为了验证后端项目是否正常启动成功 可以在win上的浏览器缩编输入一个后端的get接口来验证

2.安装nginx

因为某些linux服务器为了兼容一些特定的项目使用的老的版本的linux系统，比如我此时用的就是centOS7，因为centOS7在2024年的6月份就把此linux版本的yum源镜像归档了，所以会导致我们在使用yum源来下载一些工具的时候会出现yum报错的现象。此时别慌，可以按照以下步骤操作！

报错信息如：

Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"

解决方法

• 进入/etc/yum.repos.d目录下找到 CentOS-Base.repo
• cd /etc/yum.repos.d

• cp CentOS-Base.repo CentOS-Base.repo.backup
• vi CentOS-Base.repo
• 进入修改内容为：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

• 然后wq保存下，依次执行：
• sudo yum clean all
• sudo yum makecache

阿里云镜像源

以下两个命令都可以，执行完成后进入/etc/yum.repos.d

• curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
• wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

然后执行：

• cat CentOS-Base.repo

解析nginx

• yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
• 此时来到你安装nginx的目录

• ./configure --prefix=/usr/local/nginx --with-http_ssl_module 
• make&&make install

此时去/usr/local/nginx目录中去找配置好的nginx（此时就可以看到nginx执行文件了）

配置nginx.conf文件

（两个，一个为一开始下载的nginx文件，另一个为解析到/usr/local/nginx之后的文件）

http {include   mime.types;default_type  application/octet-stream;server {listen 443 ssl;server_name 自己解析的域名;#你解析域名的密钥文件两个（假如你都放在了/etc/Assl目录下）ssl_certificate /etc/Assl/XXXXX.pem;ssl_certificate_key /etc/Assl/XXXXX.key;location / {#访问域名就可以看到的前端项目（假如你都放在了/etc/lesaosao_lunxun_ui目录下）root  /etc/lesaosao_lunxun_ui/dist_pc;index  index.html index.htm;try_files $uri $uri/ /index.html;}location /api/ {#访问后端项目的端口（ip+端口号）proxy_pass http://xxx.xx.xx.xx:3000/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}location /images/uploadimg/ {#访问后端存放前端上传的图片目录alias /root/usr/lesaosao_lunxun/uploadimg/;}# SSL configurationsproxy_ssl_session_reuse off;proxy_ssl_protocols TLSv1.2 TLSv1.3;proxy_ssl_ciphers HIGH:!aNULL:!MD5;}server {#第二个前端项目（假如不需要使用域名访问）listen 8100;location / {#访问8100端口就可以看到的前端项目（假如你都放在了/etc/lesaosao_lunxun_ui目录下）root /etc/lesaosao_lunxun_ui/dist_web;index  index.html index.htm;try_files $uri $uri/ /index.html;}location /api/ {#访问后端项目的端口（ip+端口号）proxy_pass http://xxx.xx.xx.xx:3000/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}#因为该前端不涉及上传图片等文件所以该目录可忽略location /images/uploadimg/ {alias /images/uploadimg/;}# SSL configurationsproxy_ssl_session_reuse off;proxy_ssl_protocols TLSv1.2 TLSv1.3;proxy_ssl_ciphers HIGH:!aNULL:!MD5;}
}
events {worker_connections  1024;}

重启nginx服务！

 发现访问域名项目即可被访问到！（特殊linux需配置防火墙以及开放端口等操作）
