How to Upgrade Wialon Local from v1704 to v1804

upgrading_wialon_local

This guide describes the sequence of steps you should follow if you want to upgrade Wialon Local from version 1704 to version 1804.

In order for Wialon local version 1704 and above to function correctly, the Node.js 6.x package is required. Support for older versions of Node.js, starting with the release of 1804, is discontinued.

The official Debian 8 and Debian 9 repositories include earlier versions of packages. When installing from our distribution package, the required Node.js version is installed automatically.

Upgrade Node.js to the version 6.x if you receive a notification that the version of Node.js that is used on your server is out of date. To do this, follow the steps below.
- Log in to the terminal on behalf of the main user (root) and run the following commands:
  cd /home/wialon/wlocal/ service wlocal stop ./adf_script stop apt-get install -y curl curl -sL https://deb.nodesource.com/setup_6.x | bash - apt-get install -y nodejs npm -g install forever npm install chown -R wialon:wialon /home/wialon/ service wlocal restart
- Check the availability of your sites after they restart.
To update Node.js, you can also contact technical support. In this case, in the letter specify SSH credentials (IP, login and password) to access the server console.
The instruction is also located on the official site of the Node.js developer.

How to Upgrade Wialon Local from v1804 to v1904

When upgrading Wialon Local from version 1804 to version 1904, follow the steps below.

Make sure that the Debian operating system has been upgraded to version 9 (Stretch).

When updating from Debian 8 to Debian 9, add a line “include /etc/nginx/modules-enabled/*.conf” to the file /etc/nginx/nginx.conf . Here is an example of the received file:

user www-data;
worker_processes  2;
worker_rlimit_nofile 65535;
include /etc/nginx/modules-enabled/*.conf;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
       worker_connections  65535;
}

http {
       include       /etc/nginx/common/*;
       include       /etc/nginx/conf.d/*;
}

Add additional options (listed below) to the nginx configuration files for the admin site (/etc/nginx/conf.d/lcm.conf). Add the options to the location element of the server section of the lcm.conf file and to the configuration of other nginx involved in proxying requests. This is required to activate work using web sockets.

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";

Example of the lcm.conf configuration file:

server {
    listen        80;
    server_name    10.10.10.10;
    client_max_body_size 10000m;
    proxy_read_timeout 500;
    location /50x.html {
        root /home/wialon/wlocal/nginx/www/nginx-default;
    }    
    location / {
        if ( $args ~* dns-test ) {
            echo 1;
        }
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";       
        proxy_pass         http://localhost:8080;
    }
    access_log /var/log/nginx/lcm.access.log;
}

Install the ripgrep utility. It is required for quick reading of statistical information about the status of the server.

wget --no-check-certificate http://ftp.br.debian.org/debian/pool/main/r/rust-ripgrep/ripgrep_0.10.0-2_amd64.deb -O /tmp/ripgrep.deb
dpkg -i /tmp/ripgrep.deb

Install the version 1904 of Wialon Local.

How to Upgrade Wialon Local from v2204 to v2304

To upgrade Wialon Local from version 2204 to version 2304, follow the instruction below step by step.

Preparation

Coordinate the upgrade from version 2204 to 2304 with your personal manager.

As the upgrade requires a database conversion for the primary and backup servers, ensure that the servers have sufficient free space.

The conversion of the database (the storage directory) leads to an increase in its size up to 20%.

Install all available updates in the primary server administration system. If the administration system is installed on backup servers, install updates for it as well.
Disable the Auto-install option on the System tab of the primary and backup server administration systems.

Upgrading the operating system of backup servers

If the backup servers are already running Debian 11 (Bullseye), skip this step.

Upgrade the operating system to Debian 11 (Bullseye) for the servers with the backup module installed. To do this, follow the steps below.

Stop the backup module that runs on the backup server.
Upgrade the version of Debian.
Update the software part of the backup servers (see below).
Start the backup module.

Updating the software part of backup servers

Update the software part of the backup servers. This is necessary for the subsequent conversion of their databases.

If the backup server is running the administration system in the backup server mode, do the following:

On the System tab, in the Backup servers section, enable the Update backup server automatically option.
On the System tab, click on the icon (Redownload all modules).
Install the downloaded update.

If the backup server doesn't have the administration system installed, do the following:

Install all available updates in the primary server administration system.
Download the archive with the backup module by clicking on the Download button in the Backup servers section.
Stop the backup module.
Save the storage folder, which is located in the directory of the backup module and contains the Wialon Local database.
Reinstall the backup module.
Copy the saved storage folder to the backup module directory so that the database doesn't need to be synchronized from scratch.
Start the backup module.

Switching the distribution

Request your personal manager to switch your Wialon Local distribution from version 2204 to version 2304.
Wait for the next update with Wialon Local modules version 2204, which will be delivered to the administration system of the primary Wialon Local server after switching the distribution to version 2304.

By this time, all backup servers should be updated, launched and connected to the primary Wialon Local server.
Install the update. The entry Adding ADF_STORAGE_MSG_VERSION = v2 to wialonEnv will be displayed in the log in the administration system of the primary server:

Database conversion

After installing the update, the database conversion of the primary and backup servers begins. Depending on the size of the database, this may take several hours.

You can monitor the process of converting the primary server database in the log of the administration system. There will be a record like Set dbStats: 'X-Y' every 10 minutes. If X is equal to Y, then the conversion process is complete:

You can also check if the conversion has ended in the /home/wialon/wlocal/storage/ms/msgs_stats.txt file. All database files must be V5:

Don't stop or restart Wialon Local after the conversion is completed.

Make sure the databases on all backup servers are also converted. To do this, check the contents of the storage/ms/msgs_stats.txt file on the backup servers. All database files must be V5:

Approximately 20 minutes after the database conversion is completed, the administration system of the primary server will receive an update with Wialon Local version 2304.

Installing Wialon Local 2304

After the database conversion, you should install the update with Wialon Local version 2304. To do this, follow the steps below.

Install the update with version 2304 in the administration system of the primary Wialon Local server.
If the administration systems of backup servers are not installed, follow the steps in the Updating the software part of backup servers section. If they are installed, wait until the update arrives in the administration systems of backup servers, enable the Automatically update the backup server option for them, and install the received updates.

You can also contact technical support to upgrade from version 2204 to version 2304.
