ubuntu安装redis

一、安装

//在终端中安装Redis服务器端

sudo apt-get install redis-server

安装完成后，Redis服务器会自动启动，我们检查Redis服务器程序

//在终端中检查Redis服务器系统进程
ps -aux|grep redis

//在终端中通过启动命令检查Redis服务器状态 
netstat -nlt|grep 6379

//通过启动命令检查Redis服务器状态 
sudo /etc/init.d/redis-server status

二、访问Redis

安装Redis服务器，会自动地一起安装Redis命令行客户端程序。

启动redis—server

/usr/bin/redis-server

在本机输入redis-cli命令就可以启动，客户端程序访问Redis服务器。

三、Ubuntu14.04下安装redis-3.2.0以及开机自启动    

设置开机自启动

• 修改redis.conf

  #打开后台运行选项
  daemonize yes
  #设置日志文件路径
  logfile "/var/log/redis.log"
  

• 编写脚本

  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ sudo touch /etc/init.d/redis
  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ sudo vim /etc/init.d/redis
  

  下面是脚本的内容

  #!/bin/sh
  # chkconfig: 2345 10 90
  # description: Start and Stop redis
  
  PATH=/usr/local/bin
  REDISPORT=6379
  EXEC=/usr/local/bin/redis-server
  REDIS_CLI=/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 $CONF
          fi
          if [ "$?"="0" ]
          then
              echo "Redis is running..."
          fi
          ;;
      stop)
          if [ ! -f $PIDFILE ]
          then
              echo "$PIDFILE exists, 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|fore-reload}"
          exit 1
  esac 
  

• 添加脚本的执行权限

  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ sudo chmod +x /etc/init.d/redis
  

• 设置开机自动启动

  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ sudo update-rc.d redis defaults
  

• 使用脚本启动服务

  开启redis
  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ service redis start
  停止redis
  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ service redis stop
  重启redis
  xiaoyao@xiaoyao-virtual-machine:/usr/local/bin$ service redis restart
  

• 将机器关机，重新启动

方式一：通过命令redis-server 启动，可在命令后加上`&`号使redis以后台程序方式运行;

方式二：通过指定配置文件启动;redis-server /etc/redis/redis.conf
