第一部分：安装redis        安装环境：系统centos 6.4        安装目录： /usr/local/redis      首先到Redis官网下载安装包，或者直接使用如下命令下载： wget http://download.redis.io/releases/redis-3.0.7.tar.gz     解压到安装目录后执行 make命令：     [root@ser211 local]# tar -vxzf redis-3.0.7.tar.gz [root@ser211 redis]# make     测试是否安装成功,执行一下命令：     [root@ser211 redis]# ./usr/local/redis/src/redis-server [root@ser211 init.d]# redis-server 1074:C 03 Feb 16:34:16.941 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf 1074:M 03 Feb 16:34:16.943 * Increased maximum number of open files to 10032 (it was originally set to 1024). 1074:M 03 Feb 16:34:16.943 # Warning: 32 bit instance detected but no memory limit set. Setting 3 GB maxmemory limit with 'noeviction' policy now. _._ _.-``__ ''-._ _.-`` `. `_.

Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect. 1074:M 03 Feb 16:34:16.944 * The server is now ready to accept connections on port 6379    到这步，Redis安装成功！ 第二部分：配置redis并添加到服务       将/usr/local/redis/utils/redis_init_script脚本拷贝到/etc/init.d/redis      [root@ser211 init.d]# cp /usr/local/redis/utils/redis_init_script /etc/init.d/redis     将脚本文件做如下修改： #!/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=6379 EXEC=/usr/local/bin/redis-server CLIEXEC=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${REDISPORT}.pid CONF="/etc/redis/${REDISPORT}.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    根据脚本文件中的配置，创建数据目录/var/redis/6379,将redis-server、redis-cli移动到/usr/local/bin下，将/usr/local/redis/redis.conf移动到/etc/redis/6379.conf,并做如下修改： daemonize yes //由no改为yes，以后台方式运行 dir /var/redis/6379 //配置数据库文件存放目录  最后将redis添加为服务： [root@ser211 init.d]# chkconfig --add redis [root@ser211 redis]# service redis start Starting Redis server... [root@ser211 redis]# redis-cli 127.0.0.1:6379> get a "1" 127.0.0.1:6379> [root@ser211 init.d]# service redis stop Stopping ... Redis stopped    好了，配置完成！！！
