CentOS7 nginx server deploys web applications, detailed steps! ! !

1. Install Nginx:

sudo yum install epel-release  # 安装EPEL仓库
sudo yum install nginx         # 安装Nginx

2. Start the Nginx service:

sudo systemctl start nginx    # 启动Nginx服务
sudo systemctl enable nginx   # 设置Nginx开机自启

3. Configure firewall rules (if required):

sudo firewall-cmd --zone=public --add-port=80/tcp --permanent   # 开放HTTP 80端口
sudo firewall-cmd --reload    # 重新加载防火墙配置

4. Configure Nginx virtual host:

# 编辑Nginx配置文件
sudo vi /etc/nginx/nginx.conf


# 在http块中添加以下内容
server {
         listen       80;
         server_name  your_domain.com;  # 替换为你的域名或IP地址

         location / {
             root   /path/to/your/webapp;  # 替换为你的Web应用程序的根目录
             index  index.html index.htm;
         }
     }

5. Check whether the Nginx configuration file is correct:

sudo nginx -t

6. Reload Nginx configuration:

sudo systemctl reload nginx

7. At this time, when you access the domain name, 403 Forbidden will appear. You still need to take one step here.

# 再一次编辑Nginx配置文件
sudo vi /etc/nginx/nginx.conf
# 将第一行的权限改为root即可，大功告成，即可访问网页
user  root;
