# OpenIM RPC Service Control Script
|
|
#
|
|
# Description:
|
|
# This script provides a control interface for the OpenIM RPC service within a Linux environment. It offers functionalities to start multiple RPC services, each denoted by their respective names under openim::rpc::service_name.
|
|
#
|
|
# Features:
|
|
# 1. Robust error handling using Bash built-ins like 'errexit', 'nounset', and 'pipefail'.
|
|
# 2. The capability to source common utility functions and configurations to ensure uniform environmental settings.
|
|
# 3. Comprehensive logging functionalities, providing a detailed understanding of operational processes.
|
|
# 4. Provision for declaring and managing a set of RPC services, each associated with its unique name and corresponding ports.
|
|
# 5. The ability to define and associate Prometheus ports for service monitoring purposes.
|
|
# 6. Functionalities to start each RPC service, along with its designated ports, in a sequence.
|
|
#
|
|
# Usage:
|
|
# 1. Direct Script Execution:
|
|
# This initiates all the RPC services declared under the function openim::rpc::service_name.
|
|
# Example: ./openim-rpc-{rpc-name}.sh openim::rpc::start
|
|
# 2. Controlling through Functions for systemctl operations:
|
|
# Specific operations like installation, uninstallation, and status check can be executed by passing the respective function name as an argument to the script.
|
|
# Example: ./openim-rpc-{rpc-name}.sh openim::rpc::install
|
|
#
|
|
# Note: Before executing this script, ensure that the necessary permissions are granted and relevant environmental variables are set.
|
|
