Nginx 常用配置

Nginx

安装 Nginx

# 更新软件包，请确保服务器的软件包已经是最新的。
sudo yum update -y
# 添加 Nginx 源
sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
# 安装 Nginx
sudo yum install -y nginx
# 启动 Nginx
sudo systemctl start nginx.service
# 设置开机自启 Nginx
sudo systemctl enable nginx.service

配置 Nginx

# 使用 vim 编辑创建 文件名.conf
vim /etc/nginx/conf.d/文件名.conf

添加配置1（配置1和2可以同事监听80端口，绑定不同域名，实现一台服务器nginx同时配置多个前端网站，多个域名空格隔开）

server {
    listen 80;
    server_name 域名1 域名2 localhost;
    location / {
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:端口/;
    }
}

添加配置2

server {
    listen 80;
    server_name 域名1 域名2 localhost;
    location / {
        proxy_set_header HOST $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:端口/;
    }
}

代理静态网站 root指定磁盘目录

server {
    listen       80;
    server_name  域名1 域名2 多个域名空格隔开 localhost;
    location / {
       try_files $uri $uri/ /index.html;
       root D:\test-web;
    }
}

常用命令

检查配置是否有误

sudo nginx -t

重载/重启 Nginx 配置

sudo nginx -s reload

查看nginx安装目录

ps -ef | grep nginx

错误及解决办法

不能访问子路径错误：

location /flow {
    proxy_pass http://127.0.0.1:9083/;
}

修改：

location /flow/ {
    proxy_pass http://127.0.0.1:9083/;
}

解决：/flow 后面加个/
配置多个前端代码/a/ /b/不能访问
解决：把/a/ /b/放在根目录下面 （就是只有一个根目录，不过根目录里面可以放很多项目文件夹）
去掉请求后面的斜杠 添加在location节点里面 解决浏览器请求拼接到接口前面的诡异问题

rewrite ^/(.*)/$ /$1 permanent;

前后端分离项目部署

##前端配置
location /gov_flow {
    ##放再nginx下的/content/gov_flow目录
    alias /var/html/gov_flow;
    try_files $uri $uri/ /index.html;
    index index.html;
}
##后端接口配置            
location /stage-prod-api/ {
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE-HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://flow:9083/;
}
location /stage-test-api/{
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header REMOTE-HOST $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:8080/;
}
#两个后端项目接口合并成一个 给前端访问9991
server {
    listen       9991;
    server_name  localhost;
    location /yqt/{
        proxy_pass http://127.0.0.1:8888/yqt/;
    }
    location /ad/{
        proxy_pass http://127.0.0.1:8090/ad/;
    }
}

nginx配置ssl证书示例1

http{
  #http节点中可以添加多个server节点
  server{
      #ssl 需要监听443端口
      listen 443;
      # CA证书对应的域名
      server_name www.ilovey.live;
      # 开启ssl
      ssl on;
      # 服务器证书绝对路径
      ssl_certificate /www/server/nginx/conf.d/4467149_www.ilovey.live.pem;
      # 服务器端证书key绝对路径 
      ssl_certificate_key /www/server/nginx/conf.d/4467149_www.ilovey.live.key;
      # session超时
      ssl_session_timeout 5m;
      # 协议类型
      ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
      # ssl算法列表 
      ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
      #  是否 服务器决定使用哪种算法  on/off   TLSv1.1 的话需要开启
      ssl_prefer_server_ciphers on;
      location ^~  /zhihao/ {
          proxy_set_header Host $host;
          proxy_pass http://127.0.0.1:8080/;
      }
  }
  # 如果用户通过 http 访问 直接重写 跳转到 https 这个是一个很有必要的操作
  server{
      listen 80;
      server_name www.ilovey.live;
      rewrite ^/(.*)$ https://www.ilovey.live:443/$1 permanent;
  }
}
