redis安装和redis-cli

https://redis.io/documentation

1、安装

wget http://download.redis.io/releases/redis-4.0.2.tar.gz -O /tmp/redis-4.0.2.tar.gzcd /tmptar xf redis-4.0.2.tar.gzcd redis-4.0.2makemake install   只是安装二进制文件，默认将二进制文件安装到/usr/local/binmake  PREFIX=/usr/local/redis install

2、启动

redis-server 指定配置文件启动（可以设置认证码）cp /tmp/redis-4.0.2/redis.conf  /etc/redis.confredis-server /etc/redis.conf  

3、测试是否正常

#redis-cli pingPONG

redis-cli
命令行接口command line interface
模式：命令行|交互式

1、命令行

# redis-cli -h |more  -h <hostname>        -p <port>            -s <socket>          -a <password>        -r <repeat>     -1：无限次     -i <interval>       -n <db># redis-cli --versionredis-cli 4.0.2# redis-cli incr mycounter(integer) 1# redis-cli get mycounter"1"# redis-cli --raw get mycounter1连续查询某个key# redis-cli  -r -1 -i 1 get mycounter

2、交互式

# redis-cli127.0.0.1:6379> pingPONG127.0.0.1:6379> select 1OK127.0.0.1:6379[1]> dbsize(integer) 0127.0.0.1:6379[1]> set mycounter 1OK127.0.0.1:6379[1]> 3 get mycounter  //3次获取该key"1""1""1"

3、快速批量导入数据（https://redis.io/topics/mass-insert）

#cat data.txt | redis-cli --pipeAll data transferred. Waiting for the last reply...ERR unknown command 'ET'Last reply received from server.errors: 1, replies: 2解决：需要格式转换#unix2dos data.txt

4、特殊的操作模式

监控redis server的状态$ redis-cli --stat -i <interval>扫描大的key$ redis-cli --bigkeys以list获取所有keys$ redis-cli --scan $ redis-cli --scan |wc -l  //key的总数$ redis-cli --scan --pattern '*-11*'   //匹配某类key监控redis命令使用情况$ redis-cli monitor监控redis的延迟$ redis-cli --latencymin: 0, max: 1, avg: 0.19 (427 samples)--latency：ping命令测试，每秒100次$ redis-cli --latency-history   //15分钟取样一次min: 0, max: 1, avg: 0.14 (1314 samples) -- 15.01 seconds rangemin: 0, max: 1, avg: 0.18 (1299 samples) -- 15.00 seconds rangemin: 0, max: 1, avg: 0.20 (113 samples)^C$ redis-cli --latency -i <interval> //指定取样间隔$redis-cli --intrinsic-latency 5--intrinsic-latency It does not check the latency of a Redis instance, but the latency of the computer you are running redis-cli on.
