Redis Server​

  1. 下载 redis 安装包

    wget https://pdpublic.mingdao.com/private-deployment/offline/common/redis-6.2.16-glibc2.17-amd64.tar.gz

  2. 解压到安装目录

    tar -zxvf redis-6.2.16-glibc2.17-amd64.tar.gz
    mv redis-6.2.16-glibc2.17-amd64 /usr/local/redis

  3. 调整内核参数

    echo 'net.core.somaxconn = 32768' >> /etc/sysctl.conf
    echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf
    sysctl -p

  4. 创建 redis 数据目录

    mkdir /data/redis

  5. 修改配置文件

    cat > /usr/local/redis/redis.conf <<EOF
    bind 0.0.0.0
    protected-mode yes
    port 6379
    tcp-backlog 511
    timeout 0
    tcp-keepalive 300

    pidfile /usr/local/redis/redis.pid
    loglevel notice
    logfile /usr/local/redis/redis.log

    save 900 1
    save 300 10
    save 60 100000

    client-output-buffer-limit pubsub 0 0 0
    hz 10
    requirepass 123456
    masterauth 123456
    maxmemory 16gb

    maxclients 100000
    rename-command KEYS ""
    EOF
    • redis 认证与主从认证的密码为 123456，实际部署时注意替换

  6. 创建 redis 用户授权

    useradd -U -M -s /sbin/nologin redis
    chown -R redis:redis /usr/local/redis/ /data/redis

  7. 配置 systemd 管理

    cat > /etc/systemd/system/redis.service <<EOF
    [Unit]
    Description=Redis
    [Service]
    User=redis
    Group=redis
    TasksMax=infinity
    LimitNOFILE=102400
    LimitNPROC=infinity
    LimitCORE=0
    ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/redis.conf
    ExecStop=/usr/bin/kill \$MAINPID
    Restart=on-failure
    [Install]
    WantedBy=multi-user.target
    EOF

  8. 启动 redis 服务并加入开机自启动

    systemctl start redis
    systemctl enable redis
