什么是godis

• 使用golang实现的redis cli,二进制文件直接运行，无需任何依赖
• 支持安全模式，限制只能运行只读命令
• 支持常用cluster和alone模式的常用命令
• 带颜色的格式化输出，比原生的redis cli要更加友好和清晰

godis加入环境变量

• 下载release中对应平台的压缩包
• 解压，得到godis可执行文件
• 把godis可执行文件移动到/usr/local/bin/目录中（适用于Mac和Linux）
• Windows需要把godis所在的路径加入到系统的环境变量中

配置好之后，在命令行终端输入godis就能直接使用啦~

$ godis

Usage:
  godis [command]

  hgetall     Hash key hgetall
  hmset       Add a hash key, auto unpack jsonValue
  renamenx    Rename key, if new_key is exist return fail, else success
  sadd        Add a set key
  smembers    Get set key values
  ttl         Get key ttl

常用命令

config

• 新增配置

2021/03/12 10:29:39 not configured, please use "godis config add" to set a cluster configuration
Added cluster.

• 激活配置

Switched to cluster "local".

hash

• hmset

2021/03/12 10:35:23 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
hmset success, hash key is myhash , value is
{
  "a": "1",
  "b": "2"
}

{
  "a": "1",
  "b": "2"
}

$ godis hgetall myhash

1

$ godis hg myhash a
2021/03/12 10:40:27 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
1

set

• sadd

$ godis sadd myset a b c d
2021/03/12 10:41:35 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
sadd success, set key is myset , value is
[
  "d",
  "c",
  "a",
  "b"
]


$ godis sadd myjsonset '{"a":1}' '{"b":2}'
2021/03/12 10:42:33 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
sadd success, set key is myjsonset , value is
[
  {
    "a": 1
  },
  {
    "b": 2
  }
]

• smembers
  sget是smembers的aliase

$ godis smembers myset
2021/03/12 10:43:20 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
[
  "d",
  "c",
  "a",
  "b"
]

$ godis sget myjsonset
2021/03/12 10:43:57 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
[
  {
    "a": 1
  },
  {
    "b": 2
  }
]

安全模式

新增安全模式的配置

$ godis config add local_safe -a=127.0.0.1:6379 --desc="local safe redis client" --isSafeMode=true
2021/03/12 10:47:47 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
Added cluster.

激活安全模式的配置

$ godis config use local_safe
2021/03/12 10:49:18 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
Switched to cluster "local_safe".

安全模式正常操作

支持的所有命令：["hg", "hget", "hgetall", "hga", "sget", "smembers", "type", "config"]

$ godis hga myhash
2021/03/12 10:50:41 connect success, using alone mode, conf: local_safe, addr is [127.0.0.1:6379]
{
  "a": "1",
  "b": "2"
}

$ godis sget myjsonset
2021/03/12 10:51:10 connect success, using alone mode, conf: local_safe, addr is [127.0.0.1:6379]
[
  {
    "a": 1
  },
  {
    "b": 2
  }
]

...

临时切换配置

$ godis del myhash -c local
2021/03/12 10:59:35 connect success, using alone mode, conf: local, addr is [127.0.0.1:6379]
delete key success

-c设置当前的操作使用local这个配置，只对当前这个命令有效，不会修改默认的配置。 通过godis config ls查看，默认配置还是local_safe

$ godis config ls
2021/03/12 11:01:57 connect success, using alone mode, conf: local_safe, addr is [127.0.0.1:6379]
[
  {
    "Addrs": [
      "127.0.0.1:6379"
    ],
    "Description": "local redis client",
    "IsSafeMode": false,
    "Name": "local",
    "Password": ""
  },
  {
    "Addrs": [
      "127.0.0.1:6379"
    ],
    "Description": "local safe redis client",
    "IsSafeMode": false,
    "Name": "local_safe",
    "Password": ""
  }
]
CurrentCluster: local_safe
