环 境: CentOS 6.6s Redis 版 本 : redis- - 3.0 0 (考虑到 Redis3.0 在集群和性能提升方面的特性,rc 版为正式版的候选版,而且很快就出正式版)安装目录 : /usr/local/redis用 户 : root编译和安装所需的包:# yum install gcc tcl下载 3.0 版 Redis(当前最新版 redis-3.0.0-rc5.tar.gz,请学员们在安装时自行选用最新版)# cd /usr/local/src# wget https://github.com/antirez/redis/archive/3.0.0-rc5.tar.gz创建安装目录:# mkdir /usr/local/redis解压:# tar -zxvf 3.0.0-rc5.tar.gz# mv redis-3.0.0-rc5 redis3.0# cd redis3.0安装(使用 PREFIX 指定安装目录):# make PREFIX=/usr/local/redis install安装完成后,可以看到/usr/local/redis 目录下有一个 bin 目录,bin 目录里就是 redis 的命令脚本:redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server将 Redis 配置成服务:按上面的操作步骤,Redis 的启动脚本为:/usr/local/src/redis3.0/utils/redis_init_script将启动脚本复制到/etc/rc.d/init.d/目录下,并命名为 redis:# cp /usr/local/src/redis3.0/utils/redis_init_script /etc/rc.d/init.d/redis编辑/etc/rc.d/init.d/redis,修改相应配置,使之能注册成为服务:# vi /etc/rc.d/init.d/redis#!/bin/sh## Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6379EXEC=/usr/local/bin/redis-serverCLIEXEC=/usr/local/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pid

复制 redis 配置文件/usr/local/src/redis3.0/redis.conf 到/usr/local/redis/conf 目录并按端口号重命名为 6379.conf# cp /usr/local/src/redis3.0/redis.conf /usr/local/redis/conf/6379.conf做了以上准备后,再对 CONF 属性作如下调整:CONF="/etc/redis/${REDISPORT}.conf" 改为 CONF="/usr/local/redis/conf/${REDISPORT}.conf"(6) 更改 redis 开启的命令,以后台运行的方式执行:$EXEC $CONF & #“&”作用是将服务转到后面运行修改后的/etc/rc.d/init.d/redis 服务脚本内容为:#!/bin/sh#chkconfig: 2345 80 90## Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6379EXEC=/usr/local/redis/bin/redis-serverCLIEXEC=/usr/local/redis/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/usr/local/redis/conf/${REDISPORT}.conf"case "$1" instart)if [ -f $PIDFILE ]thenecho "$PIDFILE exists, process is already running or crashed"elseecho "Starting Redis server..."$EXEC $CONF &fi;;stop)if [ ! -f $PIDFILE ]thenecho "$PIDFILE does not exist, process is not running"elsePID=$(cat $PIDFILE)echo "Stopping ..."$CLIEXEC -p $REDISPORT shutdownwhile [ -x /proc/${PID} ]doecho "Waiting for Redis to shutdown ..."sleep 1
doneecho "Redis stopped"fi;;*)echo "Please use start or stop as first argument";;esac以上配置操作完成后,便可将 Redis 注册成为服务:# chkconfig --add redis防火墙中打开对应的端口# vi /etc/sysconfig/iptables添加:-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT重启防火墙:# service iptables restart修改 redis 配置文件设置:# vi /usr/local/redis/conf/6379.conf修改如下配置daemonize no 改为> daemonize yespidfile /var/run/redis.pid 改为> pidfile /var/run/redis_6379.pid启动 Redis 服务# service redis start将 Redis 添加到环境变量中:# vi /etc/profile在最后添加以下内容:## Redis envexport PATH=$PATH:/usr/local/redis/bin使配置生效:# source /etc/profile现在就可以直接使用 redis-cli 等 redis 命令了:关闭 Redis 服务
# service redis stop
默认情况下,Redis 开启安全认证,可以通过/usr/local/redis/conf/6379.conf 的 requirepass 指定一个验证密码。
