安裝Redis

1. 下載redis安裝包

1. 將壓縮包拷貝到/opt目錄下並且解壓縮

[root@hm707 redis-3.2.8]# tar -zxvf redis-3.2.8.tar.gz

1. 進入到解壓縮後的目錄中，執行make命令

注意：執行make時需要有gcc環境，如果沒有需要提前安裝

[root@hm707 redis-3.2.8]# yum install gcc-c++ -y

再次執行make時還是會報錯，錯誤如下

[[email protected] redis-3.2.8]# make
cd src && make all
make[1]: Entering directory `/opt/redis-3.2.8/src'
 

    CC adlist.o
In file included from adlist.c:34:
zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/opt/redis-3.2.8/src'
make: *** [all] Error 2

該錯誤是因為之前在沒有gcc環境時執行make命令後生成了一些檔案目錄導致的，只需要執行make distclean

1. 最後執行make install

[[email protected] redis-3.2.8]# make install
cd src && make install
make[1]: Entering directory `/opt/redis-3.2.8/src'

Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL
 
 install

簡單管理

1. 目錄的簡單說明

安裝完成後的可執行檔案在/usr/local/bin目錄下

[[email protected] redis-3.2.8]# cd /usr/local/bin
[[email protected] bin]# ll
total 26348
-rwxr-xr-x. 1 root root 5580327 Apr 27 23:09 redis-benchmark
-rwxr-xr-x. 1 root root   22217 Apr 27 23:09 redis-check-aof
-rwxr-xr-x. 1 root root 7829986 Apr 27 23:09 redis-check-rdb
-rwxr-xr-x. 1 root root 5709187 Apr 27 23:09 redis-cli
lrwxrwxrwx. 1 root root      12 Apr 27 23:09 redis-sentinel -> redis-server
-rwxr-xr-x. 1 root root 7829986 Apr 27 23:09 redis-server

修改配置檔案，讓redis可以後臺啟動

[root@hm707 bin]# pwd
/opt/redis-3.2.8
[root@hm707 bin]# mkdir /myredis
[root@hm707 bin]# cp redis.conf /myredis/
[root@hm707 bin]# vim /myredis/redis.conf

daemonize改為yes

################################# GENERAL #####################################

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes

啟動redis服務

[root@hm707 bin]# pwd
/usr/local/bin
[root@hm707 bin]# redis-server /myredis/redis.conf
[root@hm707 bin]# ps -ef | grep redis
root      6048     1  0 23:26 ?        00:00:00 redis-server 127.0.0.1:6379     
root      6054  2438  0 23:27 pts/1    00:00:00 grep redis

使用redis-cli -p 6379連線redis服務.
SHUTDOWN關閉服務

[root@hm707 bin]# pwd
/usr/local/bin
[root@hm707 bin]# redis-cli -p 6379
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set k1 hello
OK
127.0.0.1:6379> get k1
"hello"
127.0.0.1:6379> SHUTDOWN
not connected> exit
[root@hm707 bin]# ps -ef|grep redis
root      6075  2438  0 23:31 pts/1    00:00:00 grep redis

使用Redis-benchmark測試redis效能

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)  
-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 只顯示每秒鐘能處理多少請求數結果  
--csv              Output in CSV format  
-l                 Loop. Run the tests forever 永久測試  
-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.  

//SET/GET 100 bytes 檢測host為127.0.0.1 埠為6379的redis伺服器效能
redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100  

//5000個併發連線，100000個請求，檢測host為127.0.0.1 埠為6379的redis伺服器效能 
redis-benchmark -h 127.0.0.1 -p 6379 -c 5000 -n 100000
