標題：Redis 基本搭建

前言：

Redis是一個基於記憶體的高效能key-value資料庫，資料都儲存在記憶體中定期重新整理到磁碟，以極高的讀寫效率而備受關注。

他的特點是支援各種資料結構，stirng,hashes, list,set,和sorted sets client端對於不同資料結構是使用不同的命令。

Redis伺服器的daemon啟動程式

redis-cli是Redis的客戶端工具。關於redis-cl命令的引數說明見下表

redis-benchmark是Redis的效能測試工具

redis-check-dump dump.rdb 檢查本地資料檔案

redis-check-aof appendonly.aof 更新日誌檢查，加--fix引數為修復log檔案

Redis 主要程式流程

安裝步驟：

		wget    ---3.2.0版本
	
		tar xvzf redis-stable.tar.gz
	
		cd redis-stable
	
		make
	
		ps -ef|grep redis ---檢視redis程式是否有啟動
	
		cp -p src/redis-server /usr/local/bin/
	
		cp -p src/redis-cli /usr/local/bin/

將redis.conf檔案的daemonize引數改為yes，redis改為後臺啟動

		[root@localhost redis-stable]# grep daemonize redis.conf |grep -v "^#"
	
		daemonize yes
	
		[root@localhost redis-stable]# redis-server redis.conf --port 7777  /*預設埠6379，可透過redis-server --port更改埠*/
	
		[root@localhost redis-stable]# ps -ef |grep redis|grep -v grep
	
		root     20165     1  0 16:12 ?        00:00:00 redis-server 127.0.0.1:7777
	
		[root@localhost redis-stable]#

設定key --- set key和get key

		[root@localhost src]# redis-cli
	
		127.0.0.1:7777> ping
	
		PONG
	
		127.0.0.1:7777> set mykey somevalue
	
		OK
	
		127.0.0.1:7777> get mykey
	
		"somevalue"
	
		127.0.0.1:7777>

檢視版本：

[root@localhost src]# redis-cli --version

redis-cli 3.2.0

[root@localhost src]# redis-server --version

Redis server v=3.2.0 sha=00000000:0 malloc=jemalloc-4.0.3 bits=64 build=47622ff85e6ad599

[root@localhost src]#

		[root@localhost redis-stable]# redis-cli  --help
	
		redis-cli 3.2.0
	
		Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]
	
		  -h       Server hostname (default: 127.0.0.1).
	
		  -p           Server port (default: 6379).
	
		  -s         Server socket (overrides hostname and port).
	
		  -a       Password to use when connecting to the server.
	
		  -r         Execute specified command N times.
	
		  -i       When -r is used, waits  seconds per command.
	
		                     It is possible to specify sub-second times like -i 0.1.
	
		  -n             Database number.
	
		  -x                 Read last argument from STDIN.
	
		  -d      Multi-bulk delimiter in for raw formatting (default: \n).
	
		  -c                 Enable cluster mode (follow -ASK and -MOVED redirections).
	
		  --raw              Use raw formatting for replies (default when STDOUT is
	
		                     not a tty).
	
		  --no-raw           Force formatted output even when STDOUT is not a tty.
	
		  --csv              Output in CSV format.
	
		  --stat             Print rolling stats about server: mem, clients, ...
	
		  --latency          Enter a special mode continuously sampling latency.
	
		  --latency-history  Like --latency but tracking latency changes over time.
	
		                     Default time interval is 15 sec. Change it using -i.
	
		  --latency-dist     Shows latency as a spectrum, requires xterm 256 colors.
	
		                     Default time interval is 1 sec. Change it using -i.
	
		  --lru-test   Simulate a cache workload with an 80-20 distribution.
	
		  --slave            Simulate a slave showing commands received from the master.
	
		  --rdb    Transfer an RDB dump from remote server to local file.
	
		  --pipe             Transfer raw Redis protocol from stdin to server.
	
		  --pipe-timeout  In --pipe mode, abort with error if after sending all data.
	
		                     no reply is received within  seconds.
	
		                     Default timeout: 30. Use 0 to wait forever.
	
		  --bigkeys          Sample Redis keys looking for big keys.
	
		  --scan             List all keys using the SCAN command.
	
		  --pattern     Useful with --scan to specify a SCAN pattern.
	
		  --intrinsic-latency  Run a test to measure intrinsic system latency.
	
		                     The test will run for the specified amount of seconds.
	
		  --eval       Send an EVAL command using the Lua script at .
	
		  --ldb              Used with --eval enable the Redis Lua debugger.
	
		  --ldb-sync-mode    Like --ldb but uses the synchronous Lua debugger, in
	
		                     this mode the server is blocked and script changes are
	
		                     are not rolled back from the server memory.
	
		  --help             Output this help and exit.
	
		  --version          Output version and exit.
	
		Examples:
	
		  cat /etc/passwd | redis-cli -x set mypasswd
	
		  redis-cli get mypasswd
	
		  redis-cli -r 100 lpush mylist x
	
		  redis-cli -r 100 -i 1 info | grep used_memory_human:
	
		  redis-cli --eval myscript.lua key1 key2 , arg1 arg2 arg3
	
		  redis-cli --scan --pattern '*:12345*'
	
		  (Note: when using --eval the comma separates KEYS[] from ARGV[] items)
	
		When no command is given, redis-cli starts in interactive mode.
	
		Type "help" in interactive mode for information on available commands
	
		and settings.
	
		[root@localhost redis-stable]#
