Redis-Server 安装指南

一、安装redis

  • 使用管理员登陆，进入software目录，下载 redis

    1
    2
    cd /home/admin/software
    wget http://download.redis.io/releases/redis-2.6.16.tar.gz

  • 解压 redis 并将此目录复制到临时目录解压

    1
    2
    3
    tar xvzf redis-2.6.16.tar.gz
    mv redis-2.6.16 /opt/
    cd /opt/redis-2.6.16

  • 编译

    1
    2
    make
    make test

    注意：如果执行中遇到如下错误”You need tcl 8.5 or newer in order to run the Redis test”,请安装tcl8.5+.

    1
    yum install tcl

  • 执行完单元测试后，在 src 目录下会生成下述文件

    • redis-server
    • redis-cli

  • 将可执行文件复制到 /usr/local/bin 目录

    1
    2
    3
    4
    sudo cp /opt/redis-2.6.16/src/redis-server /usr/local/bin
    sudo cp /opt/redis-2.6.16/src/redis-cli /usr/local/bin
    sudo chown -R admin:admin /usr/local/bin/redis-server
    sudo chown -R admin:admin /usr/local/bin/redis-cli

  • 创建 redis-session、 redis-site 软连接

    1
    2
    3
    cd /usr/local/bin
    sudo ln -s /usr/local/bin/redis-server redis-site
    sudo ln -s /usr/local/bin/redis-server redis-session

  • 创建redis目录

    1
    2
    3
    4
    5
    6
    7
    sudo mkdir /etc/redis
    sudo mkdir /var/log/redis
    sudo mkdir /var/data/redis
    sudo mkdir /var/run/redis
    sudo mkdir /var/lock/redis
    sudo mkdir /var/data/redis/session
    sudo mkdir /var/data/redis/site

  • 赋予目录权限

    1
    2
    3
    4
    5
    sudo chown -R admin:admin /etc/redis
    sudo chown -R admin:admin /var/log/redis
    sudo chown -R admin:admin /var/data/redis
    sudo chown -R admin:admin /var/run/redis
    sudo chown -R admin:admin /var/lock/redis

  • 创建 redis 配置文件

    1
    2
    touch /etc/redis/session.conf
    touch /etc/redis/site.conf

  • 修改 session.conf、 site.conf 文件

    • session.conf 文件内容如下(除注释部分及缺省配置)

      # 以守护进程启动
      daemonize yes
      # 进程文件
      pidfile /var/run/redis/session.pid
      # 端口号
      port 6379
      # 日志文件
      logfile /var/log/redis/session.log
      # 关闭持久化配置
      #save 900 1
      #save 300 10
      #save 60 10000
      # 数据文件
      dbfilename session.rdb
      # 数据文件存放目录
      dir /var/data/redis/session

    • site.conf 文件内容如下(除注释部分及缺省配置)

      daemonize yes
      pidfile /var/run/redis/site.pid
      port 1221
      logfile /var/log/redis/site.log
      save 900 1
      save 300 10
      save 60 10000
      dbfilename site.rdb
      dir /var/data/redis/site

  • 启动服务

    1
    2
    redis-server /etc/redis/session.conf
    redis-server /etc/redis/site.conf

  • 检查日志输出 /var/log/redis/session.log

  • 使用redis-cli命令检验端口

    • 输入

      1
      redis-cli -p 6379

    • 输出

      1
      redis 127.0.0.1:6379>

    • 输入

      1
      redis-cli -p 1221

    • 输出

      1
      redis 127.0.0.1:1221>

  • 至此 redis 单机安装成功
