redis安装

1、解压文件夹并创建链接
ln  -s  /redis    /usr/local/redis

2、新建文件并拷贝相应的启动脚本
cp   /redis/utils/redis_init_script   /etc/init.d/redis

3、修改/etc/init.d/redis内容
REDISPORT=6379----redis启动端口
EXEC=/usr/local/redis/src/redis-server---redis文件路径
CLIEXEC=/usr/local/redis/src/redis-cli---redis文件路径
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"----实际路径

修改为：
daemonize yes
