nginx+tomcat example of accessing the project through the domain name

I was curious about how to access the project using a domain name, but it was too troublesome to get my own domain name. I needed to buy it, submit various documents, wait for review, and file it. . . I don't have any projects or things to do right now, so I'm just thinking of doing something. . .

Seeing that Tencent's server was on sale, I spent 40 yuan to buy a server with the lowest version (I was poor, so I had no choice but to use it for personal use). I have to complain about Tencent here. Why set the security level so high? Direct remote login is not possible because the IP address cannot be pinged. In addition, all ports and commands are banned. I have used Alibaba Cloud before, and the security level is not so high. After a lot of trouble, the configuration is as follows

Then I started the formal operation. I built a project casually and made it accessible. I started it through tomcat and entered http://localhost:8080/demo/login/index.do to enter the page. Next, I needed to change localhost to the domain name I bought before. I had never done it before, so I asked Baidu directly. I found out that the server.xml configuration in tomcat needed to be changed. I changed localhost to my own domain name and the port number to the commercial port number 80. Unfortunately, it didn't work. After starting it, I couldn't access the page (this may be due to my configuration, and there are other configurations that I didn't pay attention to. The great god who saw the article can give me guidance). I used other methods and found on Baidu that the domain name needs to be resolved. The configuration is as follows

The record value is the domain name of the server. Start the system and visit http://www.XXX.com:8080/demo/login/index.do. The page is accessed successfully. It is considered a small accomplishment.

After that, we need to use nginx+tomcat to access it. Let's experience load balancing simply. I downloaded a windows version of nginx, clicked nginx.exe directly, and visited http://localhost to enter the page.

Then start two tomcats, the ports are 8081 and 8082 respectively, the nginx port is 8080, and then configure the nginx.conf file

#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

events {
 worker_connections 1024;
}

http {
 include 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 logs/access.log main;
 sendfile on;
 #tcp_nopush on;
 #keepalive_timeout 0;
 keepalive_timeout 65;
 #gzip on;
 upstream lssxxxyss.com{
  server 139.199.127.123:8081 weight=1; #weight is the weight, which can be regarded as the proportion of the number of visits server 139.199.127.123:8082 weight=2;
 } 
 server {
  listen 8080;
  server_name lssxxxyss.com www.lssxxxyss.com;
  #charset koi8-r;
  #access_log logs/host.access.log main;
  location / {
   #root html;
   #index index.html index.htm;
   proxy_pass http://lssxxxyss.com;
  }
  #error_page 404 /404.html;
  . . . Ignore the following. . .
}

Next, visit the page and enter the address http://lssxxxyss.com:8080/sshDemo/login/index.do. After multiple visits, different pages are displayed (in order to distinguish the login pages of the two tomcat projects, it shows that the load is indeed balanced)

Additional knowledge: Nginx configuration Java project access under Tomcat

The principle is to use nginx's reverse proxy

The Nginx installation path is generally: /usr/local/nginx

Insert code snippet here> |-- client_body_temp
|-- conf #This is the directory of all Nginx configuration files, extremely important| |-- fastcgi.conf #Configuration file for fastcgi related parameters| |-- fastcgi.conf.default #Original backup of fastcgi.conf| |-- fastcgi_params #Fastcgi parameter file| |-- fastcgi_params.default
| |--koi-utf
| |-- koi-win
| |-- mime.types #media type,
| |-- mime.types.default

Use tail -f access.log to view the website user access information in real time| |-- error.log #This is the error log file of Nginx. If Nginx has problems such as startup failure, be sure to check this error log| `-- nginx.pid #Nginx's pid file.

|-- scgi_temp #temporary directory`-- uwsgi_temp #temporary directory 9 directories, 21 files

Create a vhost directory in the /usr/local/nginx directory, and then create a tomcats.conf file in the vhosts folder

The contents of the tomcats.conf file are as follows:

For example, there are two Java projects that need to be accessed using Tomcat. The configuration is as follows

server
 {
  listen 80;

  server_name ce1.xdr630.top;#Domain name for accessing tomcat service#charset koi8-r;

  #access_log logs/host.access.log main;

  location / {
    proxy_pass http://127.0.0.1:8081;#Tomcat service address root html;
    index index.html index.htm;
  }

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

server
 {
  listen 80;
  server_name ce2.xdr630.top;#Domain name for accessing tomcat service#charset koi8-r;
  #access_log logs/host.access.log main;
  location / {
    proxy_pass http://127.0.0.1:8082;#Tomcat service address root html;
    index index.html index.htm;
  }
  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
   root html;
  }
 }

Open the nginx.conf file under conf in the nginx installation directory (my directory is /usr/local/nginx/conf/nginx.conf)

Add at the bottom of the file

include /usr/local/nginx/vhosts/*; (includes all virtual machine host files)

Then find in the middle of the file

 location / {
   proxy_pass http://192.168.0.148:8080; (add this to specify the address of your own local tomcat)
   root html;
   index index.html index.htm;
  }

Restart tomcat and nginx. In fact, Nginx generally does not need to be restarted. It can be controlled by calling the executable with the -s parameter

Reload the configuration file:

/usr/local/nginx/sbin/nginx -t //Check the syntax first
/usr/local/nginx/sbin/nginx -s reload //Reload configuration

Check the Nginx startup status:

ps -a | grep nginx

You can also restart the nginx service lnmp restart to access the tomcat service directly through the domain name

Replenish:

Start Nginx to view help: ./nginx -h

Start Nginx: cd sbin; ./nginx

The above example of nginx+tomcat accessing the project through the domain name is all the content that the editor shares with you. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM.
