CenterOS中安裝Redis及開機啟動設置

Redis安裝

從官方下載最新Redis進行安裝，官網地址：http://redis.io/download

$ wget http://download.redis.io/releases/redis-3.2.3.tar.gz
$ tar xzf redis-3.2.3.tar.gz
$ cd redis-3.2.3
$ make
$ make install

Redis啟動

RedisServer /path/to/redis.conf

Redis關閉(默認port為6379)

RedisCli -p port -a Password shutdown  

查看Reids進程

ps -ef|grep redis

設置Redis開機啟動

1：配置init腳本，把代碼存為Reids，放到/etc/init.d/

注意事項:

　　1) 最上面的注釋的意思是，redis服務必須在運行級2，3，4，5下被啟動或關閉，啟動的優先級是90，關閉的優先級是10。 　　　　

　　2) 如果執行命令出現$'/r':command not found，這個問題是在Windows下換行和linux下換行不同，可以通過Nodepad++進行轉換。

2：設置腳本權限

chmod +x /etc/init.d/redis  

3：設置開機啟動

sudo chkconfig redis on  

4：使用方法

service redis start   #或者 /etc/init.d/redis start
service redis stop   #或者 /etc/init.d/redis stop
