README
Apache-2.0

1.Docker安装

  1. 启动容器
docker run -itd --name redis-test -p 6379:6379 redis --bind 0.0.0.0
# 带密码
docker run -d --name redis-test -p 6379:6379 redis --requirepass "shengjie"
  1. 生产级启动
docker run -d --privileged=true -p 6380:6379 
-v /docker/redis/conf/redis.conf:/etc/redis/redis.conf 
-v /docker/redis/data:/data 
--name redistest2 
redis:4.0 
redis-server /etc/redis/redis.conf --appendonly yes

参数说明:
--privileged=true:容器内的root拥有真正root权限,否则容器内root只是外部普通用户权限
-v /docker/redis/conf/redis.conf:  /etc/redis/redis.conf:映射配置文件
-v /docker/redis/data:/data:映射数据目录
redis-server /etc/redis/redis.conf:指定配置文件启动redis-server进程
--appendonly yes:开启数据持久化
 --bind 0.0.0.0 监听所有ip.
  • 其他方法
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)
       ./redis-server -v or --version
       ./redis-server -h or --help
       ./redis-server --test-memory <megabytes>

Examples:
       ./redis-server (run the server with default conf)
       ./redis-server /etc/redis/6379.conf
       ./redis-server --port 7777
       ./redis-server --port 7777 --replicaof 127.0.0.1 8888
       ./redis-server /etc/myredis.conf --loglevel verbose
  1. 连接redis 执行redis-cli
docker exec -it redis-test /bin/bash

1.1 设置数据

  • 字符串

    set key "asd"

    set key "asd" nx # 不要替换

    set key "asd" xx # 可以替换

    get key

  • hashap

    HMSET NAME field1 value1 field2 value2

    HGET NAME field2

  • 列表

    lpush name item1 item2 item3

    lrange name start end

  • 集合set

    sadd name set1 set2

    smembers name

  • zset(有序集合)

    zadd key score member

    zrangebyscore name start end

  • 删除

    del name

  • 获取所有的key keys *

1.2 redis 命令行

redis-cli 连接本地数据库 redis-cli

redis-cli -h host -p port -a password

1.3 各种命令

序号 命令及描述
1 DEL key 该命令用于在 key 存在时删除 key。
2 DUMP key 序列化给定 key ,并返回被序列化的值。
3 EXISTS key 检查给定 key 是否存在。
4 EXPIRE key seconds 为给定 key 设置过期时间,以秒计。
5 EXPIREAT key timestamp EXPIREAT 的作用和 EXPIRE 类似,都用于为 key 设置过期时间。 不同在于 EXPIREAT 命令接受的时间参数是 UNIX 时间戳(unix timestamp)。
6 PEXPIRE key milliseconds 设置 key 的过期时间以毫秒计。
7 PEXPIREAT key milliseconds-timestamp 设置 key 过期时间的时间戳(unix timestamp) 以毫秒计
8 KEYS pattern 查找所有符合给定模式( pattern)的 key 。
9 MOVE key db 将当前数据库的 key 移动到给定的数据库 db 当中。
10 PERSIST key 移除 key 的过期时间,key 将持久保持。
11 PTTL key 以毫秒为单位返回 key 的剩余的过期时间。
12 TTL key 以秒为单位,返回给定 key 的剩余生存时间(TTL, time to live)。
13 RANDOMKEY 从当前数据库中随机返回一个 key 。
14 RENAME key newkey 修改 key 的名称
15 RENAMENX key newkey 仅当 newkey 不存在时,将 key 改名为 newkey 。
16 [SCAN cursor MATCH pattern] [COUNT count] 迭代数据库中的数据库键。
17 TYPE key 返回 key 所储存的值的类型。

1.4 数据库

  • 选择数据库 默认有十六个数据库 select 3
  • 显示数据库数据大小 dbsize
  • 清空所有数据库 flushall
  • 清空当前数据库flushdb

2.权限设置

3.benckmark 性能测试服务


 -h <hostname>      Server hostname (default 127.0.0.1)
 -p <port>          Server port (default 6379)
 -s <socket>        Server socket (overrides host and port)
 -c <clients>       Number of parallel connections (default 50)
 -n <requests>      Total number of requests (default 10000)
 -d <size>          Data size of SET/GET value in bytes (default 2)
 -k <boolean>       1=keep alive 0=reconnect (default 1)
 -r <keyspacelen>   Use random keys for SET/GET/INCR, random values for SADD
  Using this option the benchmark will get/set keys
  in the form mykey_rand:000000012456 instead of constant
  keys, the <keyspacelen> argument determines the max
  number of values for the random number. For instance
  if set to 10 only rand:000000000000 - rand:000000000009
  range will be allowed.
 -P <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).
 -q                 Quiet. Just show query/sec values
 --csv              Output in CSV format
 -l                 Loop. Run the tests forever
 -t <tests>         Only run the comma-separated list of tests. The test
                    names are the same as the ones produced as output.
 -I                 Idle mode. Just open N idle connections and wait.```

4.集群

4.1 主从备份

  • master
docker run -d --privileged=true --net=host \
-v /home/root/redis-jq/conf/redis.conf:/etc/redis/redis.conf \
--name master redis \
redis-server /etc/redis/redis.conf --port 6380


# config
#port 6380
requirepass shengjie
bind 0.0.0.0
daemonize no
save 900 1
#masterauth shengjie
#appendonly yes
replica-priority 1

  • slave
docker run -d --privileged=true --net=host \
-v /home/root/redis-jq/conf/slave.conf:/etc/redis/redis.conf  redis \
redis-server /etc/redis/redis.conf --port 6383



# config
#port 6381
slaveof 127.0.0.1 6380
requirepass shengjie
bind 0.0.0.0
daemonize no
#save 900 1
masterauth shengjie
#appendonly yes

## 或者登陆成功之后执行
replicaof id port
# 查询集群消息
info replication
取消赋值
replicaof no one 
  • 其他命令
# 查看角色
role
## 或者登陆成功之后执行
replicaof id port
# 查询集群消息
info replication
取消赋值
replicaof no one 
# 从服务器可写
--replica-read-only no/yes
config set replica-read-only no
# 当不一致的时候怎么办呢?
#  当做主服务的优先级,越小有有限。
replica-priority 1

4.2 redis sentinel

可以在主从备份中将备份角色转换为主角色。

docker run -d --privileged=true --net=host \
-v /home/root/redis-jq/conf/sentinel.conf:/etc/redis/redis.conf  redis \
redis-sentinel /etc/redis/redis.conf --port 6378
  • 配置文件
sentinel monitor master1 127.0.0.1 6380 1
port 16380
sentinel auth-pass master1 shengjie
  • 操作
# 指定端口通过redis-cli 登陆
# 列出所有masters
sentinel masters
# 列出name
sentinel master name 
# 获取slaves
sentinel  slaves master-naem

4.3 集群cluster

  • 修改配置文件
# 配置文件添加
cluster-enalbed yes
  • 启动多个redis服务
# docker 启动五个主master,分别启动多个sentinel进行监控。
# 实际上用sentinel已经没用了。
# 端口号从30001-30005
  • 创建集群
# 可以连接到任何一个master然后手动添加集群节点
cluster meet ip port
# 查看节点
cluster nodes

​ redis-cli --cluster是Redis客户端附带的集群管理工具,它的create子命令接受任意多个节点的IP地址和端口号作为参数,然后使用这些节点组建起一个Redis集群。create子命令允许使用多个可选参数,其中可选参数cluster-replicas用于指定集群中每个主节点的从节点数量。在上面的命令调用中,该参数的值为1,这表示我们想要为每个主节点设置一个从节点。

  • 至少三个主,如果一主一从那就需要有六个服务。
redis-cli --cluster  create 127.0.0.1:30001  127.0.0.1:30002 127.0.0.1:30003 \
127.0.0.1:30004 127.0.0.1:30005 127.0.0.1:30006  --cluster-replicas 1 -a shengjie
  • 连接集群
redis-cli -c -p 30001
