Installing Tomcat + Nginx in Ubuntu Cloud server
Info: This post is one of the articles in context of this post: Huawei Cloud ECS server notes

I have just now installed TomCat and Nginx on our Huawei Cloud server. In this post, I would like to note the operations I've done in this task.

TomCat

I have created file ~/launchers/tomcat_8888.sh and filled it with the following content:

docker rm -f tomcat_8888
docker run \
 -it -d --privileged=true \
 --name tomcat_8888 \
 --net bridge-network \
 -p 8888:8080  \
 -v /home/jemaloQ/www_server:/usr/local/tomcat/webapps \
 -v /home/jemaloQ/docker/www_server/logs:/usr/local/tomcat/logs \
 tomcat:latest
Enter fullscreen mode Exit fullscreen mode

Launch TomCat as docker container:

sudo sh ~/launchers/tomcat_8888.sh
Enter fullscreen mode Exit fullscreen mode

Now create a webpage for testing tomcat:

cd ~/www_server
mkdir home
cd home/
touch index.html
Enter fullscreen mode Exit fullscreen mode

Put the following html code in this index.html file:

<!DOCTYPE html>
<html>
<head>
<title>Test TomCat Servie</title>
</head>
<body>

<h1>Tomcat over docker is working</h1>
<p> Port = 8888 </p>

</body>
</html>
Enter fullscreen mode Exit fullscreen mode

Open the browser, try http://myip:8888/test, voilà:

Nginx

I use the following cmd line for installing Nginx in a native way:

sudo apt install nginx-full
Enter fullscreen mode Exit fullscreen mode

Check if Nginxservice is running:

service nginx status
Enter fullscreen mode Exit fullscreen mode

The default conf file of Nginx "nginx.conf" can be found in directory /etc/nginx/. Usually, we do not need to modify this file. In this file, there is one line as: include /etc/nginx/conf.d/*.conf;, meaning that Nginx shall take into account all .conf user files created in /etc/nginx/conf.d repository.

Below are operations that I have performed (Some may require sudo permission):

touch /etc/nginx/conf.d/myconf.conf
vi /etc/nginx/conf.d/myconf.conf
Enter fullscreen mode Exit fullscreen mode

In myconf.conf file, I add the following lines:

server {
    listen       80;
    server_name 111.22.133.117 sssbot.cn localhost;
    # server_name localhost;


    gzip            on;
    gzip_types      text/plain application/xml text/css application/javascript;
    gzip_min_length 1000;



        location /demo/industry_safety {
                        proxy_pass http://111.22.133.117:8888/industry_safety;
        }

        location ~* /demo/industry_safety/([a-z]+)$   {
                   rewrite /demo/industry_safety/([a-z]+)$ /demo/industry_safety/;                                                                              
                        }


        location /test {
          proxy_pass http://111.22.133.117:8888/test;
        }

        location / {
                        default_type application/octet-stream;
                        include /etc/nginx/mime.types;
                        root /usr/share/nginx/html;
                        index  index.html index.htm;
                        try_files $uri $uri/  /index.html;

        }


    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}
Enter fullscreen mode Exit fullscreen mode

Make nginx reload all its configurations:

nginx -s reload
Enter fullscreen mode Exit fullscreen mode

Check if http://myip:8888/test/ has been redirected to http://myip/test:

I have a real SaaS project named "industry_safety" whose front-end is a Vue-based website. There are many static resources in this project which may bring problems after URL redirection. As shown in /etc/nginx/conf.d/myconf.conf file, I have redirected original url http://myip:8888/industry_safety/ to http://myip/demo/industry_safety/.

Check it now and it works :
