根据提示输入yes

Linux 配置Redis集群为开机自启动==========
1.vim /etc/init.d/redisc
将下方脚本写入redisc文件中

!/bin/sh

chkconfig: 2345 80 90

Simple Redis init.d script conceived to work on Linux systems

as it does use of the /proc filesystem.

注册为系统服务
chkconfig --add redisc
配置为开机自启动
chkconfig redisc on

以后可以使用命令来控制Redis 集群的启动和关闭
启动：service redisc start

关闭：service redisc stop

权限不够时
chmod a+x /etc/init.d/redisc

启动redis报错：/var/run/redis_6379.pid exists, process is already running or crashed

这是由于redis在停止时，直接使用kill命令，导致进程没有杀干净。

解决方案：执行命令 删除redis_6379.pid 文件
rm -rf /data/app/redis/redis-5.0.0/7001/redis_7001.pid
rm -rf /data/app/redis/redis-5.0.0/7002/redis_7002.pid
rm -rf /data/app/redis/redis-5.0.0/7003/redis_7003.pid
rm -rf /data/app/redis/redis-5.0.0/7004/redis_7004.pid
rm -rf /data/app/redis/redis-5.0.0/7005/redis_7005.pid
rm -rf /data/app/redis/redis-5.0.0/7006/redis_7006.pid
