CentOS 下 redis 安装与配置

蕴美395

　　1、到官网上找到合适版本下载解压安装

[iyunv@java src]# wget -c http://redis.googlecode.com/files/redis-2.4.7.tar.gz
[iyunv@java src]# tar -zxv -f redis-2.4.7.tar.gz
[iyunv@java src]# cd /usr/local/src/redis-2.4.7
[iyunv@java redis-2.4.7]# make  #编译，编译完成后就可以测试使用了，但是为了做成后台服务，最好把它安装到系统上
[iyunv@java redis-2.4.7]# make install  #安装会把redis的命令被拷贝到/usr/local/bin下面
　　
　　2、配置redis.conf文件

[iyunv@java redis-2.4.7]# cp ./redis.conf /etc/redis.conf
把daemonize no 改成 daemonize yes，这样启动redis时就会成会后台服务
useradd redis
mkdir -p /var/lib/redis
mkdir -p /var/log/redis
chown redis.redis /var/lib/redis  #db文件放在这里，要修改redis.conf的dir属性

　　
　　3、配置启动脚本

###########################
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/etc/redis.conf"
case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
while [ -x ${PIDFILE} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
exit 1
esac
##############################
　　
　　把上面代码放到 /etc/init.d/redis里保存，并添加执行属性
　　

[iyunv@java redis-2.4.7]# chmod +x /etc/init.d/redis
　　
　　4、启动和测试redis

[iyunv@java redis-2.4.7]# /etc/init.d/redis start   #启动
[iyunv@java redis-2.4.7]# /etc/init.d/redis stop    #停止
[iyunv@java redis-2.4.7]# ps -aux | grep redis    #查看redis进程是否启动
启动redis客户端进行测试
[iyunv@java redis-2.4.7]# redis-cli
redis 127.0.0.1:6379> set test test
OK
redis 127.0.0.1:6379> get test
"test"
redis 127.0.0.1:6379> exit
