Redis學習——01.redis安裝

下載下傳

tar -xzvf redis-.tar.gz
cd redis-
make
make install
           

執行完之後會在/usr/local/bin下生成redis相關的可執行檔案

➜  ~ cd /usr/local/bin
➜  bin git:(master) ll -h redis*
-rwxr-xr-x   mahaiyuan  admin    K     : redis-benchmark
-rwxr-xr-x   mahaiyuan  admin    K     : redis-check-aof
-rwxr-xr-x   mahaiyuan  admin   M     : redis-check-rdb
-rwxr-xr-x   mahaiyuan  admin   K     : redis-cli
lrwxr-xr-x   mahaiyuan  admin    B     : redis-sentinel -> redis-server
-rwxr-xr-x   mahaiyuan  admin   M     : redis-server
           

• redis-server redis伺服器
• redis-cli Redis指令行用戶端
• redis-benchmark Redis性能測試工具
• redis-check-aof AOF檔案修複工具

停止redis

➜  ~ redis-cli shutdown
23870:M 01 Aug 23:00:38.226 # User requested shutdown...
23870:M 01 Aug 23:00:38.226 * Saving the final RDB snapshot before exiting.
23870:M 01 Aug 23:00:38.227 * DB saved on disk
23870:M 01 Aug 23:00:38.227 # Redis is now ready to exit, bye bye...
[1]  + 23870 done       redis-server
           

用戶端使用

➜  ~ redis-cli
127.0.0.1:6379>
           

or

➜  ~ redis-cli -h  -p 
:>
           

自定義啟動和停止腳本

➜  redis ll -h
total 
-rw-r--r--@  mahaiyuan  staff    K     : redis.conf
-rwxr-xr-x   mahaiyuan  staff   K     : redis.sh
           

redis.sh内容如下

#!/bin/bash
path=$(cd "$(dirname "$0")"; pwd)
cd $path

# check pid exists

   redisps=`ps -ef | grep redis-server | grep `

   else
      psid=
   fi
}

         echo "(pid=$psid) [Success]"
      else
         echo "[Failed]"
      fi
   fi
}

## 停止redis操作
