Nginx – WordPress

Example Nginx configuration file for WordPress CMS:

server {
    server_name artem.services;
    root /var/www/html/artem_services;
    index index.php;

    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_index index.php;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        log_not_found off;
    }
}

Docker Swarm over TLS

In this example, there are 3 servers with Docker installed on it. If docker is not installed, you can see the installation here.

There will be one manager and two workers:

Master – manager (IP: 1.1.1.1)
Slave_1 – worker (IP: 1.1.2.1)
Slave_2 – worker (IP: 1.1.2.2)

Required ports for Docker Swarm to work: 2376 and 2377 (TCP). Make sure that the swarm participants are allowed to interact.

Creating Docker Swarm

On the Master server, do the following:

docker swarm init --advertise-addr 1.1.1.1

We get a message like:

Swarm initialized: current node (ssmj2qyqxejd72p6sa9jinnza) is now a manager.

To add a worker to this swarm, run the following command:

docker swarm join \
--token SWMTKN-1-3qg9vovt2mxyfu1dfj2nocmkzd3i351z1z0aapd9jxxu7mafff-93r77xv8mrqsgfkf9nei902zk \
1.1.1.1:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

Swarm is created and there is one manager in it. Information on the swarm can be viewed with the command:

docker info

 Docker – API over TCP

All steps are relevant for distributions with systemd (tested on CentOS 7 and Ubuntu 18.04)

We look at the Docker launch command:

grep "ExecStart" /usr/lib/systemd/system/docker.service

Ubuntu 18.04 has a different path, "/lib/systemd/system/docker.service"

 

We get something similar:

ExecStart=/usr/bin/dockerd

Now create the "override.conf" file, just enter:

systemctl edit docker

We insert the following there:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375
