redis的安装及使用

安装redis

• 操作步骤

  # 解压
  tar -zxvf redis-5.0.14/.tat.gz -C /urs/local/
  
  # 重命名，易读
  mv /urs/local/redis-5.0.14/ /urs/local/redis/ 
  
  # 安装环境依赖包
  yum install -y gcc-c++
  
  # 编译【异常执行：make MALLOC=libc，避免jemalloc重载Linux下的ANSI C的malloc和free函数】
  cd /urs/local/redis/
  make
  
  # 安装
  make install
  
  # 验证
  redis-server
  

后台启动

• 编辑redis配置文件

  vim /usr/local/redis/redis.conf
  

• 修改可后台启动：daemonize yes

  ################################# GENERAL #####################################
  
  # By default Redis does not run as a daemon. Use 'yes' if you need it.
  # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
  daemonize yes
  

• 验证

  redis-server /usr/local/redis/redis.conf
  

systemctl 管理redis

• 创建服务脚本

  vim /usr/lib/systemd/system/redis.service
  

• 修改服务脚本

  # 在/usr/lib/systemd/system/路径下创建redis.service
  [Unit]
  Description=Redis server
  After=syslog.target network.target remote-fs.target nss-lookup.target
  
  [Service]
  Type=forking
  ExecStart=/bin/bash -c '/usr/local/bin/redis-server /usr/local/redis/redis.conf'
  ExecStop=/bin/bash -c '/usr/local/bin/redis-cli shutdown'
  Restart=always
  PrivateTmp=true
  
  [Install]
  WantedBy=multi-user.target
  

• 重新加载systemctl配置

  systemctl daemon-reload
  

• 启停redis服务

  # 启停redis
  systemctl start|restart|stop|status redis.service   
  
  # 开机启动/不启动redis服务
  systemctl enable|disable redis.service
