今日分享redis开机自启动。

Redis开机自启动是指在计算机开机时，Redis服务会自动启动，无需手动操作，这样可以方便用户在服务器上使用Redis服务，提高工作效率，下面我们来介绍如何实现Redis开机自启动。

一、安装Redis

我们需要在服务器上安装Redis，可以通过以下命令安装：

sudo apt-get update
sudo apt-get install redis-server

二、创建Redis配置文件

为了方便管理Redis服务，我们可以创建一个配置文件，在/etc/redis/目录下创建一个名为redis.conf的文件，并添加以下内容：

bind 127.0.0.1
protected-mode yes
port 6379
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
pidfile /var/run/redis_6379.pid
loglevel notice
logfile ""
databases 16
always-show-logo yes
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
dir ./
slave-serve-stale-data yes
slave-read-only yes
repl-diskless-sync no
repl-disable-tcp-nodelay no
slave-priority 100
lazyfree-lazy-eviction no
lazyfree-lazy-expire no
lazyfree-lazy-server-del no
slave-lazy-flush no
appendonly no
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
aof-use-rdbcache no
lua-time-limit 5000
slowlog-log-slower-than 10000
slowlog-max-len 128
latency-monitor-threshold 0
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-size -2
list-compress-depth 0
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-bufferLimit slave 0 0 0
hz 10
aof-rewrite-incremental-fsync yes

三、修改Redis服务配置文件权限

为了让Redis服务能够读取配置文件，我们需要修改配置文件的权限：

sudo chmod 644 /etc/redis/redis.conf

四、创建Redis开机自启动脚本(以Ubuntu为例)

接下来，我们需要创建一个Redis开机自启动脚本，在/etc/init.d/目录下创建一个名为redis的脚本，并添加以下内容：

“`bash

!/bin/sh
