Linux 安装Nginx

步骤一：安装依赖包

# 一键安装上面四个依赖
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
           

步骤二：下载并解压安装包

官方下载地址：https://nginx.org/en/download.html

# 创建一个文件夹
cd /usr/local
mkdir nginx
cd nginx
# 下载tar包
wget https://nginx.org/download/nginx-1.20.2.tar.gz
# 解压
tar -xvf nginx-1.20.2.tar.gz
           

步骤三：安装nginx

# 进入nginx目录
cd /usr/local/nginx/nginx-1.20.2
# 配置
./configure
# 编译安装
make
make install
           

步骤四：配置nginx

# 打开配置文件
vi /usr/local/nginx/conf/nginx.conf
           

nginx配置示例

user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
  worker_connections  1024;
}
http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;
  log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';
  access_log  /var/log/nginx/access.log  main;
  sendfile        on;
  client_max_body_size 10m;
  keepalive_timeout  65;
  upstream backend {
      server 172.18.108.85:3001;
  }

  server {
    listen       80;
    server_name  localhost;
    location / {
      root   /app;
      index  index.html;
      try_files $uri $uri/ /index.html;
    }
    location /api/
    {
        proxy_pass http://backend/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header REMOTE-HOST $remote_addr;

        #缓存相关配置
        #proxy_cache cache_one;
        #proxy_cache_key $host$request_uri$is_args$args;
        #proxy_cache_valid 200 304 301 302 1h;

        #持久化连接相关配置
        proxy_connect_timeout 3000s;
        proxy_read_timeout 86400s;
        proxy_send_timeout 3000s;
        #proxy_http_version 1.1;
        #proxy_set_header Upgrade $http_upgrade;
        #proxy_set_header Connection "upgrade";

        add_header X-Cache $upstream_cache_status;

        #expires 12h;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
      root   /usr/share/nginx/html;
    }

  }
}

           

查找nginx位置

[[email protected] nginx-1.20.2]# whereis nginx
nginx: /usr/local/nginx
           

步骤五：将nginx添加到全局变量

ln -s /usr/local/nginx/sbin/nginx /usr/local/bin/
           

常用命令

# 启动命令
nginx
# 停止命令
nginx -s top
# 重启命令
nginx -s reload
