docker中的redis与持久化一、docker的安装 1、docker版本 2、docker安装 3、docker相

一、docker的安装

1、docker版本

2、资源规格

三、节点172.25.39.156

redis服务配置

1、redis的conf

####
#Redis配置文件示例。
####

##配置说明
#单位不区分大小写，因此1GB 1gb 1gB都是一样的。

##可以指定redis端口默认端口为6379
#port 6379

##后台启动
#daemonize yes

##开放注释的话只能来自同一主机的客户端连接
#注释这一行，表示Redis可以接受任意ip的连接
# bind 127.0.0.1

##关闭保护模式
protected-mode no

##主服务器认证密码，当主服务器故障，变为从节点时需要这个配置项
masterauth H3yuncom

##设定密码(可选，如果这里开启了密码要求，slave的配置里就要加这个密码)
requirepass H3yuncom

##配置日志路径，为了便于排查问题，指定redis的日志文件目录
logfile "/var/log/redis.log"

#设置pid文件路径
pidfile /var/run/redis.pid

2、docker run

# 
docker run -d --name redis_master \
-p 6379:6379 \
-v /data/redis/conf/redis.conf:/etc/redis/conf/redis.conf \
-v /data/redis/log/redis.log:/var/log/redis.log \
registry.cn-hangzhou.aliyuncs.com/h3bpm/redis:4-alpine3.8 \
redis-server /etc/redis/conf/redis.conf

3、docker ps


[root@KSSYYV181780 ~]# docker ps

4、docker inspect redis

哨兵配置

1、sentinel的conf

##哨兵监听端口
port 26379

##哨兵输出日志(注意创建日志权限问题，如有问题可以注释)
logfile "/var/log/redis_sentinel.log"

#工作目录
dir "/data"

四、节点172.25.39.157

redis服务配置

1、redis的conf

####

#Redis配置文件示例。

####

##配置说明
#单位不区分大小写，因此1GB 1gb 1gB都是一样的。
  
##可以指定redis端口默认端口为6379
#port 6379

##后台启动
#daemonize yes

##开放注释的话只能来自同一主机的客户端连接
#注释这一行，表示Redis可以接受任意ip的连接
# bind 127.0.0.1

##关闭保护模式
protected-mode no

##主服务器认证密码，当主服务器故障，变为从节点时需要这个配置项
masterauth H3yuncom

##设定密码(可选，如果这里开启了密码要求，slave的配置里就要加这个密码)
requirepass H3yuncom

##配置日志路径，为了便于排查问题，指定redis的日志文件目录
logfile "/var/log/redis.log"

#设置pid文件路径
pidfile /var/run/redis.pid

##哨兵监听端口
port 26379

##哨兵输出日志(注意创建日志权限问题，如有问题可以注释)
logfile "/var/log/redis_sentinel.log"

#工作目录
dir "/data"

#redis主节点信息(主节点名称、IP、端口)，及哨兵投票选举数量 等于2有两台哨兵投票主节点
sentinel myid 54ce98c35cc70d70ea978e8f4ec2a3cc0cbaff46


##哨兵master节点宕机后，认定master不可用，默认30000 时间（毫秒）
sentinel deny-scripts-reconfig yes

##redis的主从节点服务的名称和密码 用于哨兵连接
sentinel monitor mymaster 172.25.39.157 6379 2

# Generated by CONFIG REWRITE
sentinel auth-pass mymaster H3yuncom
