Redis Startup/Shutdown/Restart service script under Linux

Scripting Features:

enable the normal startup, shutdown, and restart of a single Redis instance in a multi-instance redis single-machine scenario. Complete the following common functions for system standard Services : Start|stop|status|restart

Note: The Redis program code masks the HUP signal and does not support the online reload configuration file, so the reload function is removed.

This script optimizes the Redis stop and restart logic to resolve data loss issues when the original Redis script is closed.

Script Name:

Redis # can be named in multiple instances by instance port , such as : redis-6001 , to differentiate between different instances

Script usage:

1. Create a new Redis file in the /etc/rc.d/init.d/ directory and copy the contents of the script

2. Chkconfig--add Redis # Registration Service

3. chkconfig --level 345 redis on # specifies that the service runs at 3,4,5 levels

4. I redis program installed in the/usr/local/redis directory, configured as/usr/local/redis/bin/redis.conf, such as installed in other directories, please modify their own

Script Parameters :

redis-p [Port] [Start|stop|status|restart]

Parameter Description:

- p [port]: Specify the port for the Redis instance, the server for the multi-instance

start: Redis Service to start the specified port

Stop: The Redis service that stops the specified port

Status: Process status

Restart: Turn off the Redis service before starting the redis Service

Note: When you do not specify a port, the script defaults to the Redis that launches the 6379 Port

Usage examples:

service redis-p 6381 start # starts redis for 6381 Port instances

/etc/init.d/redis Start # default start of Redis for 6379 Port instances
