redis安装

安装

安装到自己定义目录中，记住目录
#自启动添加 vim /etc/init.d/redis

centos

1. 准备 init.d 脚本（可以搜索 redis rpm，找到rpm包后解压获取相应的init.d脚本，然后在再其基础上修改配置项）

   #!/bin/sh
   # chkconfig: 2345 10 90
   # description:redis
   ##
   ## redis        init file for starting up the redis daemon
   ##
   ## chkconfig:   - 20 80
   ## description: Starts and stops the redis daemon.
   #
   ## Source function library.
   #
   REDISPORT=6379 
   EXEC=/data0/soft/redis/redis-3.0.3/src/redis-server 
   REDIS_CLI=/data0/soft/redis/redis-3.0.3/src/redis-cli 
   
   PIDFILE=/var/run/redis.pid 
   CONF="/data0/soft/redis/redis-3.0.3/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  

   并修改其中的配置项 vi /etc/init.d/redis

   exec="/data/software/redis/redis-2.8.14/src/redis-server"
   pidfile="/data/store/redis/redis.pid"                                                                 # 应当与redis.conf中的配置保持一致
   REDIS_CONFIG="/data/software/redis/redis-2.8.14/redis.conf"
   REDIS_USER=redis

   最后为 init.d 脚本修改权限

   chmod u+x /etc/init.d/redis
   chkconfig --add redis
   chkconfig --list redis
   chkconfig --level 345 redis on

2. 启动

   service redis start

#centos7

vi /usr/lib/systemd/system/redis.service
   
   systemctl enable redis

systemctl start redis

批量删除

redis-cli -h 127.0.0.1 -p 7001 -c keys “xxxx*” | xargs redis-cli -h 127.0.0.1 -p 7001 -c del {}
