Hengshi Documentation

Software Upgrade

In this example, the installation path is /opt/hengshi, the download path is ~/pkgs, preparation files are introduced in the section Installation.

Stop the Old Version Services

$ sudo su - hengshi             #Switch to the product runtime user
$ cd /opt/hengshi               #Enter the installation target directory
$ bin/hengshi-sense-bin stop all    #Stop the old version services

Installation

Please first check if the contents of the two configuration files, hosts and vars.yml, in the directory cluster-conf, which is at the same level as the "hengshi-sense-[version]" directory, are correct. Refer to the section introduced in Installation - Setting Up Cluster Information

$ sudo su - hengshi             #Switch to the product runtime user
$ cd ~/pkgs/hengshi-sense-[version]           #Switch to the decompression target directory
$ ./hs_install -m cluster -c ../cluster-conf    #Execute cluster installation

The installation program reports the following information, the status of each node [unreachable=0, failed=0], indicating the installation is successful:

PLAY RECAP ****************************************************************
Node-A : ok=18   changed=3    unreachable=0    failed=0    skipped=2    rescued=0    ignored=0
Node-B : ok=18   changed=3    unreachable=0    failed=0    skipped=2    rescued=0    ignored=0
Node-C : ok=18   changed=3    unreachable=0    failed=0    skipped=2    rescued=0    ignored=0 

Update Dependencies

This step requires the executing user to have sudo permissions on each machine. After successful execution, you can close the sudo permissions (the program does not need sudo permissions for daily operation)

$ sudo su - hengshi             #Switch to the product runtime user
$ cd /opt/hengshi                 #Enter the installation target directory
$ bin/hengshi-sense-bin init-os all  #Initialize OS

Start

After execution, confirm the operation status and service status in sequence

$ sudo su - hengshi             #Switch to the product runtime user
$ cd /opt/hengshi                #Enter the installation target directory
$ bin/hengshi-sense-bin start all   #Start new version services

1. Operation is successful with the following prompt: (each machine unreachable=0, failed=0)

PLAY RECAP ***********************************************************************
Node-A              : ok=4    changed=3    unreachable=0    failed=0    skipped=2    rescued=0    ignored=0
Node-B              : ok=3    changed=2    unreachable=0    failed=0    skipped=3    rescued=0    ignored=0
Node-C              : ok=3    changed=2    unreachable=0    failed=0    skipped=3    rescued=0    ignored=0

2. Execute the check command to view the "ACTIVE"/"NOT ACTIVE" status of the service, refer to Operation - Check Status
