云服务器部署Node.js项目的方法步骤(小白系列)

# 查看公网ip
# 以下为示例公网ip
ssh root@150.77.1.85

# As root
curl -sL https://rpm.nodesource./setup_12.x | bash -

# No root privileges 
curl -sL https://rpm.nodesource./setup_12.x | sudo bash -

yum install -y nodejs

#如需编译c++插件
yum install g-c++ make
# or: yum groupinstall 'Development Tools'

~$ node -v
v12.16.1
~$ npm -v
6.13.0

npm config set registry "https://registry.npm.taobao.

npm install pm2 -g

# 需确认安装以下软件
yum -y install g pcre-devel zlib-devel openssl openssl-devel

cd /usr/local
mkdir nginx
cd nginx
#下载最新版nginx
wget http://nginx./download/nginx-1.16.1.tar.gz
tar -zxvf nginx-1.16.1.tar.gz
# 拷贝到nginx文件夹
cp -r /usr/local/nginx/nginx-1.16.1/ /usr/local/nginx/
./configure
make
make install

cd conf
vi nginx.conf

#修改配置文件
#省略其他不做修改篇配置

http {
  server_tokens off;
  include    mime.types;
  default_type application/octet-stream;
  #aess_log logs/aess.log main;
  sendfile    on;
  #tcp_nopush   on;

  #keepalive_timeout 0;
  keepalive_timeout 65;

  gzip on;
  
  # 修改此处 nginx会自动加载enabled-server狼蚁网站SEO优化所有的配置文件
  include /usr/local/nginx/enabled-server/;
  ...
}

vi default.conf
# 配置文件
upstream nodepro {
  server 127.0.0.1:3000; #项目运行的端口号， 按实际修改
  keepalive 64;
}

server {
  listen 80; #要监听的端口号
  server_name xxxx. .xxxx.; # 服务器名称，ip地址或域名，可以写多个，用空格隔开

  location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Nginx-Proxy true;
    proxy_set_header Connection "";
    proxy_pass http://nodepro; # 这里要和最上面upstream后的应用名一致，可以自定义
  }
}

cd ..
./nginx -t
# 修改成功
nginx: the configuration file //server/nginx/conf/nginx.conf syntax is ok
nginx: configuration file //server/nginx/conf/nginx.conf test is suessful

./nginx

pm2 start app.js
