Redis主从复制环境搭建(基于 CentOS 7.9)

作者:互联网

Redis主从复制(基于 CentOS 7.9)

1. 单机 redis 安装

  1. 下载源码包

https://download.redis.io/releases/redis-6.2.6.tar.gz

  1. 解压缩

    tar -zxvf redis-6.2.6.tar.gz
    
  2. 安装依赖

    yum install gcc-c++ -y
    
  3. 编译安装

    cd redis-6.2.6/
    make && make install
    
  4. 创建 redis 专属目录

    mkdir -p /usr/local/redis/working
    
  5. 拷贝 redis.conf 至 redis 专属目录

    cp redis.conf /usr/local/redis/6379.conf
    
  6. 修改相关配置

    vim 6379.conf
    
    daemonzie yes
    dir /usr/local/redis/working
    bind 0.0.0.0
    # 如需设置密码
    requirepass xxxx
    
  7. 拷贝启动脚本并修改相关代码

    cp redis_init_script /etc/init.d/
    vim /etc/init.d/redis_init_script
    # 修改配置文件路径
    CONF="/usr/local/redis/${REDISPORT}.conf"
    # 自启配置
    #chkconfig: 22345 10 90
    #description: Start and Stop redis
    
  8. 设置自启

    chkconfig redis_init_script on
    
  9. 启动 redis 并检查

    ./redis_init_script start
    ps -ef |grep redis
    

2. 主从复制

  1. 编辑从配置文件

    replicaof master-node 6379
    masterauth root
    
  2. 重启从 redis

    ./redis_init_script stop
    ./redis_init_script start
    
  3. 主 redis 查看
