Nginx server nginxconf configuration file description
Record the configuration file description of the Nginx server nginx.conf here, and some comments are collected and networked.

Start the process, usually set to be equal to the number of cpu
worker_processes 1 ;
Global error log and PID file

pid /var/run/nginx.pid;
Working mode and maximum number of connections
events {
use epoll; #epoll is a method of multiplexing IO (I/O Multiplexing), but it is only used for Linux2.6 and above kernels, which can greatly improve the performance of nginx

}
Set up the http server and use its reverse proxy function to provide load balancing support
http {
#Set the mime type, the type is defined by the mime.type file
include /etc/nginx/mime.types;

#Set log format
access_log /var/log/nginx/access.log;
<code>#sendfile 指令指定 nginx 是否调用 sendfile 函数(zero copy 方式)来输出文件,对于普通应用, #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用,可设置为 off,以平衡磁盘与网络I/O处理速度,降低系统的uptime. sendfile on; #tcp_nopush on; #连接超时时间 #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; #开启gzip压缩 gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; #设定请求缓冲 client_header_buffer_size 1k; large_client_header_buffers 4 4k; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; #设定负载均衡的服务器列表 upstream mysvr { #weigth参数表示权值,权值越高被分配到的几率越大 #本机上的Squid开启3128端口 server 192.168.8.1:3128 weight=5; server 192.168.8.2:80 weight=1; server 192.168.8.3:80 weight=6; } </code>
server {
#Listen to port 80
listen 80;
#Definition Use www.xx.com to access
server_name www.xx.com;
<code> #设定本虚拟主机的访问日志 access_log logs/www.xx.com.access.log main; #默认请求 location / { root /root; #定义服务器的默认网站根目录位置 index index.php index.html index.htm; #定义首页索引文件的名称 fastcgi_pass www.xx.com; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; include /etc/nginx/fastcgi_params; } # 定义错误提示页面 error_page 500 502 503 504 /50x.html; location = /50x.html { root /root; } #静态文件,nginx自己处理 location ~ ^/(images|javascript|js|css|flash|media|static)/ { root /var/www/virtual/htdocs; #过期30天,静态文件不怎么更新,过期可以设大一点,如果频繁更新,则可以设置得小一点。 expires 30d; } #PHP 脚本请求全部转发到 FastCGI处理. 使用FastCGI默认配置. location ~ \.php$ { root /root; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/www/www$fastcgi_script_name; include fastcgi_params; } #设定查看Nginx状态的地址 location /NginxStatus { stub_status on; access_log on; auth_basic "NginxStatus"; auth_basic_user_file conf/htpasswd; } #禁止访问 .htxxx 文件 location ~ /\.ht { deny all; } } </code>
}
The above are some basic configurations. The biggest benefit of using Nginx is load balancing
If you want to use load balancing, you can modify the configuration of the http node as follows:
Set the http server , using its reverse proxy function to provide load balancing support
http {
#Set the mime type, the type is defined by the mime.type file
include /etc/nginx/mime.types;
default_type application/octet-stream;
#Set log format
access_log /var/log/nginx/access.log;
<code>#省略上文有的一些配置节点 #。。。。。。。。。。 #设定负载均衡的服务器列表 upstream mysvr { #weigth参数表示权值,权值越高被分配到的几率越大 server 192.168.8.1x:3128 weight=5;#本机上的Squid开启3128端口 server 192.168.8.2x:80 weight=1; server 192.168.8.3x:80 weight=6; } </code>
upstream mysvr2 {
The #weigth parameter represents the weight. The higher the weight, the greater the chance of being assigned
<code>server 192.168.8.x:80 weight=1; server 192.168.8.x:80 weight=6; } </code>
#The first virtual server
server {
#Listen to port 80 of 192.168.8.x
listen 80;
server_name 192.168.8.x;
<code> #对aspx后缀的进行负载均衡请求 location ~ .*\.aspx$ { root /root; #定义服务器的默认网站根目录位置 index index.php index.html index.htm; #定义首页索引文件的名称 proxy_pass http://mysvr ;#请求转向mysvr 定义的服务器列表 #以下是一些反向代理的配置可删除. proxy_redirect off; #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; #允许客户端请求的最大单文件字节数 client_body_buffer_size 128k; #缓冲区代理缓冲用户端请求的最大字节数, proxy_connect_timeout 90; #nginx跟后端服务器连接超时时间(代理连接超时) proxy_send_timeout 90; #后端服务器数据回传时间(代理发送超时) proxy_read_timeout 90; #连接成功后,后端服务器响应时间(代理接收超时) proxy_buffer_size 4k; #设置代理服务器(nginx)保存用户头信息的缓冲区大小 proxy_buffers 4 32k; #proxy_buffers缓冲区,网页平均在32k以下的话,这样设置 proxy_busy_buffers_size 64k; #高负荷下缓冲大小(proxy_buffers*2) proxy_temp_file_write_size 64k; #设定缓存文件夹大小,大于这个值,将从upstream服务器传 } } </code>

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

How to configure Nginx in Windows? Install Nginx and create a virtual host configuration. Modify the main configuration file and include the virtual host configuration. Start or reload Nginx. Test the configuration and view the website. Selectively enable SSL and configure SSL certificates. Selectively set the firewall to allow port 80 and 443 traffic.

How to configure an Nginx domain name on a cloud server: Create an A record pointing to the public IP address of the cloud server. Add virtual host blocks in the Nginx configuration file, specifying the listening port, domain name, and website root directory. Restart Nginx to apply the changes. Access the domain name test configuration. Other notes: Install the SSL certificate to enable HTTPS, ensure that the firewall allows port 80 traffic, and wait for DNS resolution to take effect.

How to confirm whether Nginx is started: 1. Use the command line: systemctl status nginx (Linux/Unix), netstat -ano | findstr 80 (Windows); 2. Check whether port 80 is open; 3. Check the Nginx startup message in the system log; 4. Use third-party tools, such as Nagios, Zabbix, and Icinga.

The methods that can query the Nginx version are: use the nginx -v command; view the version directive in the nginx.conf file; open the Nginx error page and view the page title.

Create a container in Docker: 1. Pull the image: docker pull [mirror name] 2. Create a container: docker run [Options] [mirror name] [Command] 3. Start the container: docker start [Container name]

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".

Starting an Nginx server requires different steps according to different operating systems: Linux/Unix system: Install the Nginx package (for example, using apt-get or yum). Use systemctl to start an Nginx service (for example, sudo systemctl start nginx). Windows system: Download and install Windows binary files. Start Nginx using the nginx.exe executable (for example, nginx.exe -c conf\nginx.conf). No matter which operating system you use, you can access the server IP
