Redis3.0.7安裝

1、安裝redis

   環境：centos7/redis3.0.7（其它版本安裝方法一致）

#mkdir /usr/local/redis

進入此文件夾，解壓官網下載的redis-3.0.7.tar.gz 或是使用下面命令在線下載，

wget http://download.redis.io/releases/redis-3.0.7.tar.gz

#tar -zxvf redis-3.0.7.tar.gz(解壓)
#make(編譯，編譯結束後src文件夾下會多出redis－server，redis-cli等腳本)

測試一下：

[root@ser211 redis]# ./usr/local/redis/src/redis-server

此時redis安裝成功。

2、配置redis並添加到服務

將/usr/local/redis/utils/redis_init_script腳本拷貝到/etc/init.d/redis

cp -r /usr/local/redis/redis-3.0.7/utils/redis_init_script /etc/init.d
mv redis_init_script redis(將redis_init_script重命名爲redis)

打開腳本並修改爲下面這樣：

#!/bin/sh  
#chkconfig: 2345 80 90  （加了這一行是後面要把redis添加成系統服務的標識，不加的話後面會報服務 redis 不支持 chkconfig）
# Simple Redis init.d script conceived to work on Linux systems  
# as it does use of the /proc filesystem.  
  
REDISPORT=6379  
EXEC=/usr/local/bin/redis-server  
CLIEXEC=/usr/local/bin/redis-cli  
  
PIDFILE=/var/run/redis.pid （保持跟conf裏面的pid一張，否則開和關pid不同，會出現pid已存在不能啓動或不存在不能關閉等類錯誤） 
CONF="/etc/redis/${REDISPORT}.conf"  
  
case "$1" in  
    start)  
        if [ -f $PIDFILE ]  
        then  
                echo "$PIDFILE exists, process is already running or crashed"  
        else  
                echo "Starting Redis server..."  
                $EXEC $CONF  
        fi  
        ;;  
    stop)  
        if [ ! -f $PIDFILE ]  
        then  
                echo "$PIDFILE does not exist, process is not running"  
        else  
                PID=$(cat $PIDFILE)  
                echo "Stopping ..."  
                $CLIEXEC -p $REDISPORT shutdown  
                while [ -x /proc/${PID} ]  
                do  
                    echo "Waiting for Redis to shutdown ..."  
                    sleep 1  
                done  
                echo "Redis stopped"  
        fi  
        ;;  
    *)  
        echo "Please use start or stop as first argument"  
        ;;  
esac

仔細閱讀腳本中的配置，建立數據目錄/var/redis/6379,將redis-server、redis-cli移動到/usr/local/bin下，將/usr/local/redis/redis.conf移動到/etc/redis/6379.conf,並作以下修改：

daemonize yes //由no改成yes，之後臺方式運行  
dir /var/redis/6379 //配置數據庫文件存放目錄

最後將redis添加爲服務：

#  chkconfig --add redis

測試：

# service redis start
Starting Redis server...

打開客戶端：

[root@run]# service redis start
Starting Redis server...
[root@run]# redis-cli
127.0.0.1:6379> set hi hello
OK
127.0.0.1:6379> get hi
"hello"
127.0.0.1:6379>

關閉：

[root@run]# service redis stop
Stopping ...
Redis stopped

到此安裝配置完成
