Linux under Redis boot/shutdown/Restart service script __linux

Scripting Features:

A single Redis instance is implemented to redis the normal startup, shutdown, and restart of multiple instances. Complete the following common functions of System standard service: Start|stop|status|restart

Note: The Redis program code shields the HUP signal, does not support the online overload configuration file, therefore removes the reload function.

This script optimizes the Redis stop and restart logic to resolve data loss problems when the original Redis script closes.

Script Name:

Redis #在多实例里可以按实例端口, such as: redis-6001 naming, to distinguish between different instances

Scripting Usage:

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

2. Chkconfig--add Redis #注册服务

3. Chkconfig--level 345 Redis on #指定服务在3, 4, 5 levels not running

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

Script Parameters:

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

Parameter description:

-P [Port]: Specifies the port for the Redis instance, the server for multiple instances

Start: Start the Redis service for the specified port

Stop: Stops the Redis service for the specified port

Status: Process Status

Restart: First turn off the Redis service, then start the Redis service

Note: When no port is specified, the script defaults to the boot 6379 port Redis

Usage Example:

Service Redis-p 6381 Start #启动6381端口实例的redis

/etc/init.d/redis Start #默认启动6379端口实例的redis
