centos下的Redis的安装和使用

简介

Redis 是一个高性能的key-value数据库。

准备

下载：http://redis.io/download 下载
redis-3.2.0.tar.gz 的文件

系统环境
yum -y install gcc-c++ tcl

安装

install redis

tar xzf redis-3.2.0.tar.gz
cd redis-3.2.0
./configure
make && make test
make install

服务配置

设置为服务

保存以下代码到/etc/init.d/redis (在utils/redis_init_script脚本基础上修改的)

#!/bin/sh
#
# chkconfig:   2345 90 10
# 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
CONF="/etc/redis/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
;;
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

默认配置文件

mkdir -p /etc/redis
cp redis.conf /etc/redis
vi /etc/redis/redis.conf
把 daemonize no 一行换成
daemonize yes

设置开机启动

chkconfig --add redis
chkconfig redis on #设置开机启动
service redis start

配置文件详解

基本使用

redis 目录相关可执行文件列表

/usr/local/bin/redis-benchmark  ## 性能测试工具
/usr/local/bin/redis-check-aof  ## 用于修复出问题的AOF文件
/usr/local/bin/redis-check-dump ## 用于修复出问题的dump.rdb文件
/usr/local/bin/redis-check-rdb  ## 用于修复出问题的rdb文件
/usr/local/bin/redis-cli        ## 客户端程序
/usr/local/bin/redis-server     ## 服务端程序

测试连接

[root@vagrant-centos64 /]# ./usr/local/bin/redis-cli
127.0.0.1:6379> set ff aaa
OK
127.0.0.1:6379> get ff
"aaa"
127.0.0.1:6379> set key value [EX seconds] [PX milliseconds] [NX|XX]
