redis介紹不再累贅

1、安裝gcc，因為Redis是用C語言寫的，所以需要gcc進(jìn)行編譯
yum install gcc -y
2、下載redis-2.8.9.tar.gz
http://download.redis.io/releases/redis-2.8.9.tar.gz
3、安裝Redis
      tar xf redis-2.8.9.tar.gz 
      cd redis-2.8.9
      make MALLOC=libc
      make PREFIX=/usr/local/redis install
4、安裝完成以后查看目錄以及文件
      [root@salt-server bin]# pwd
      /usr/local/redis/bin
      [root@salt-server bin]# ls
      redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis-server
5、命令解釋
      redis-server:redis服務(wù)器的daemon啟動程序
      redis-cli：redis命令行操作工具
      redis-benchmark：redis性能測試工具
      redis-check-aof：對更新日志appendonly.aof檢查
      redis-check-dump：用于本地數(shù)據(jù)庫rdb文件的檢查
6、配置啟動服務(wù)
          設(shè)置環(huán)境變量：
              vim /etc/profile
              PATH=$PATH:/usr/local/redis/bin
    	      source /etc/profile
    	   拷貝配置文件：
    	       mkdir /usr/local/redis/conf
    	       cp redis-2.8.9/redis.conf /usr/local/redis/conf
    	       echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf && sysctl -p  
     	  啟動服務(wù)：redis-server /usr/local/redis/conf/redis.conf &
7、啟動成功正常反饋如下
        [root@salt-server ~]# redis-server /usr/local/redis/conf/redis.conf &
        [1] 11736
        [root@salt-server ~]# [11736] 27 Jan 09:16:07.772 * Increased maximum number of open files to 10032 (it was originally set to 1024).

        [11736] 27 Jan 09:16:07.773 # Server started, Redis version 2.8.9
        [11736] 27 Jan 09:16:07.773 * The server is now ready to accept connections on port 6379
        
        
        
8、基本操作
        關(guān)閉redis：redis-cli shutdown 

	可直接輸入redis-cli進(jìn)去交互式
	[root@salt-client1 ~]# redis-cli 
	127.0.0.1:6379> 
    輸入值并取值測試
	[root@salt-client1 ~]# redis-cli 
	127.0.0.1:6379> set Test 001			        //設(shè)置一個Test值為001
	OK										
	127.0.0.1:6379> get Test				//獲取Test的值
	"001"
	127.0.0.1:6379> del Test				        //刪除一個值
	(integer) 1
	127.0.0.1:6379>keys *					//取所有值  
9、客戶端連接使用
	[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379
	172.16.10.133:6379> 
      也可以不登錄直接賦值
	[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379 set Test 789
	OK
	[root@salt-client1 ~]# redis-cli -h 172.16.10.133 -p 6379 get Test
	"789"     	  
     	
10、redis安全
	為redis客戶端設(shè)置外部連接密碼
	vim /usr/local/redis/conf/redis.conf
	修改requirepass如下：
		requirepass a)s$M7F57TN58$8
	重啟redis
	redis-cli shutdown
	redis-server /usr/local/redis/conf/redis.conf &
	
直接登錄測試會提示認(rèn)證失敗需要指定密碼
	[root@salt-server ~]# redis-cli 
	127.0.0.1:6379> set d 1
	(error) NOAUTH Authentication required.
	127.0.0.1:6379>
	
指定密碼登錄
	[root@salt-server ~]# redis-cli 
	127.0.0.1:6379> auth a)s$M7F57TN58$8
	OK
