Could not connect to Redis at 127.0.0.1:6379: Connection refused

记录一次redis开机自启失败的案例。

开机启动后输入redis-cli

报错

[root@MiWiFi-R4CM-srv ~]# redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Could not connect to Redis at 127.0.0.1:6379: Connection refused

当我们输入redis-server的时候，发现是可以启动的，是前台启动的。

通过命令行：输入redis的基本连接信息，发现

看到这里，我就发现了，这个启动的目录不就是redis刚下载的那个目录吗？

Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

现在重心又移到这个开机自启脚本上来了。

于是我输入命令：./redis_6379 start
报错如下：找到原因了，找不到6379文件夹，导致起不来，忘记什么时候删除过了，应该是演示企业备份，容灾恢复的时候弄的。

。

看了一下这个配置脚本文件，没有关于/var/redis/6379文件夹相关的字眼。

没有相关的脚本。

修改下：

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

# chkconfig:   2345 90 10
