1、单实例安装git

测试环境 | Centos 7 |
虚拟机 | vbox |
redis版本 | redis 5.0.5 |
1.编译安装redisredis
#使用wget从官网如今redis数据库tar压缩包 $ wget http://download.redis.io/releases/redis-5.0.5.tar.gz #使用tar解压tar压缩包 $ tar xzf redis-5.0.5.tar.gz #进入redis解压后的目录 $ cd redis-5.0.5 #使用make编译安装redis数据库,直接make会报错,详细错误信息查看第5节错误分析内容 $ make MALLOC=libc
2.redis编译测试shell
#直接make test报错,须要安装相关依赖包,运行测试时候须要tcl-Tool Command Language 包 $ yum install tcl #执行make test 测试 $ make test
测试结果以下:
数据库
3.运行redis数据库服务器
运行完成编译后,在源码文件夹中的src文件夹中会生成redis相关的二进制文件。运行编译好的二进制文件启动redis数据库:
The binaries that are now compiled are available in the src directory. Run Redis with:并发
#运行redis-server 二进制执行文件,启动redis服务端程序。 $ src/redis-server
redis server启动以下图:
dom
可使用redis-cli命令链接数据库与数据库服务端进行交互。
You can interact with Redis using the built-in client:socket
#运行redis-cli启动数据库客户端,链接默认redis数据库 $ src/redis-cli #测试redis数据库,插入一个foo bar 键值对 redis> set foo bar #插入成功 OK #获取foo key的值 redis> get foo "bar"
4.redis性能测试ide
redis 数据库自带性能测试工具,工具名称:redis-benchmark,使用此工具对数据库进行性能测试。函数
Invalid option "-help" or option argument missing Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests>] [-k <boolean>] -h <hostname> Server hostname (default 127.0.0.1) -p <port> Server port (default 6379) -s <socket> Server socket (overrides host and port) -a <password> Password for Redis Auth -c <clients> Number of parallel connections (default 50) -n <requests> Total number of requests (default 100000) -d <size> Data size of SET/GET value in bytes (default 3) --dbnum <db> SELECT the specified db number (default 0) -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 expand the string __rand_int__ inside an argument with a 12 digits number in the specified range from 0 to keyspacelen-1. The substitution changes every time a command is executed. Default tests use this to hit random keys in the specified range. -P <numreq> Pipeline <numreq> requests. Default 1 (no pipeline). -e If server replies with errors, show them on stdout. (no more than 1 error per second is displayed) -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. Examples: Run the benchmark with the default configuration against 127.0.0.1:6379: $ redis-benchmark Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1: $ redis-benchmark -h 192.168.1.1 -p 6379 -n 100000 -c 20 Fill 127.0.0.1:6379 with about 1 million keys only using the SET test: $ redis-benchmark -t set -n 1000000 -r 100000000 Benchmark 127.0.0.1:6379 for a few commands producing CSV output: $ redis-benchmark -t ping,set,get -n 100000 --csv Benchmark a specific command line: $ redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0 Fill a list with 10000 random elements: $ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__ On user specified command lines __rand_int__ is replaced with a random integer with a range of values selected by the -r option.
use redis-benchmark tools test redis performance .
#实例同时执行 1000 个请求来检测性能 ./redis-benchmark -n 1000 -q
#测试存取大小为100字节的数据包的性能 redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
#100个并发链接,100000个请求,检测host为localhost 端口为6379的redis服务器性能 redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000
5.错误记录与分析
直接make报以下错误:
缘由是jemalloc重载了Linux下的ANSI C的malloc和free函数。解决办法:make时添加参数。
make MALLOC=libc
运行后编译成功。以下图:
