[root@localhost 6379]#1.2.2 上传redis.conf到conf文件夹
1.2.2.1 将redis.conf文件从官网下载
【示意图：redis.conf文件官网下载】
1.2.2.2 上传redis.conf到conf文件夹
【示意图：上传redis.conf到conf文件夹】
1.2.3 创建日志文件redis.log并修改可写入权限
1.2.3.1 创建日志文件redis.log
【命令：创建日志文件redis.log】
touch redis.log【示例】
[root@localhost redis]# ls
6379
[root@localhost redis]# cd 6379
[root@localhost 6379]# ls
conf data log
[root@localhost 6379]# cd log

[root@localhost 6379]#1.2.3.2 修改redis.log可写入权限
【命令：修改redis.log可写入权限】
chmod 777 redis.log【示例】
[root@localhost 6379]# ls

1.2.4 修改redis.conf文件
【命令：修改redis.conf文件】
vim redis.conf【示例】
[root@localhost log]# cd ..
[root@localhost 6379]# ls
conf data log
[root@localhost 6379]# cd conf
[root@localhost conf]# ls
redis.conf
[root@localhost conf]# vim redis.conf
进入redis.conf配置文件后
先输入命令 :set number 显示行数
再insert进入插入（即可修改）
【之后修改内容如下：】
第75行： bind 0.0.0.0 # ip 允许远程连接
第94行： protected-mode no
第98行： port 6379
第304行： logfile "/var/log/redis.log" # 容器内的日志位置
第1254行：appendonly yes # 持久化
requirepass 123456 # 密码（可以不设）【示意图】
