Linux Redis 做成系统服务

概述

系统：CentOS 7.6

Redis安装后启动方式：redis-server /xxx/xxx/redis.conf。若不指定配置文件，则redis-server不会读取任何配置文件，而是使用自身携带固定配置信息启动。

若想将redis做成系统服务，则需在 /etc/init.d 目录下添加一个配置文件，文件中指定要启动的程序，如何可以使用系统服务的启停方式启动redis。

方法

在/etc/init.d目录下新建/打开文件 redis。

cd /etc/init.d
vim redis

填写如下内容：

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

### BEGIN INIT INFO

                do
                    echo "Waiting for Redis to shutdown ..."
