自动下载安装redis

     由于开发的同事想在它本地的虚拟机玩一下redis缓存，当即给他写了一个脚本，现在贴在这里，有需要的朋友可以看看：（此脚本大致包含了创建用户以及密码，下载编译安装redis，修改配置文件，启动redis服务，还是比较简单的）

############################ install_redis.sh ###############################

#!/bin/bash

# define the function of create password

create_passwd(){

    a=(a b c d e f A B C D E F @ $ % 0 1 2 3 4 5 6 7 8 9)

    for ((i=0;i<10;i++));do

        echo -n ${a[$RANDOM % ${#a[@]}]}

    done

    echo

}

# create redis user and give it password

useradd redis

password=`create_passwd`

echo $password >> /home/redis/redis_password.txt

echo $password | passwd --stdin redis

# after download redis,compile and install redis

yum -y install wget

cd /root/src/ || mkdir -p /root/src && cd /root/src/

wget http://download.redis.io/releases/redis-3.2.3.tar.gz

tar xf redis-3.2.3.tar.gz

cd /root/src/redis-3.2.3

make

make PREFIX=/usr/local/redis install

cp /root/src/redis-3.2.3/redis.conf /usr/local/redis/

sed -i 's/daemonize no/daemonize yes/g' /usr/local/redis/redis.conf

# change the authority of redis-installed dir and startup redis service

chown -R redis:redis /usr/local/redis/

su - redis

cd /usr/local/redis/bin/

./redis-server ../redis.conf

echo "welcome to use redis service"

大致上就这么多，具体脚本展示的美化部分，大家根据自己的审美看着来吧，到此一游.......
